How to breathe fresh air in frog weather

1.Do we need fresh air system?

As a professional air purifier and air fan manufacturer，we know air pollution becomes more and more serious, we have to reflect on whether we have a solution to the serious air pollution.

We advocate a healthy lifestyle and we advocate a very green living environment. Only work and live in a good air quality environment ,we can keep a clear mind, make our day more efficient to do things a day. So we have been exploring a way to make our indoor air cleaner, so that the air quality within 24 hours is the standard we monitor every day.

Next, we are going to meet this standard of air quality, and we are going through the new air system to clean the indoor air within 24 hours. The AMX ventilation system is an intelligent purification system that can purify indoor air. It is now being used in the clean air market.

I've seen people who have a room full of plants that soak up polluting gases in order to clean the air inside. This can really make our room green, but we're just having some misconceptions about the fact that the plants don't fully absorb the pollutants in the house. It can be partially improved to some extent, but it also has many limitations, which is that plants can't fully absorb indoor pollutants.

 The fresh air system can absorb pollution gas in 24 hours , which can purify our indoor air more directly. So now with the introduction of the fresh air system, our indoor air can achieve a healthy standard, which has greatly improved our quality of life.With the Guangdong AMX electric appliance co., Ltd’s , it can make you feel like live in the forest and the fresh air around you in every corner.

 　

2. Differences between the fresh air system and the air purifier

First of all, the fresh air system is through purification module to the indoor air purification after delivery to the appropriate space, to increase indoor oxygen content, neutralization and reduce the concentration of harmful gases and particulates; At the same time, high concentration of harmful gas and particulate matter are discharged outside, thus further reducing the concentration of harmful gas and particulate matter.

And the purifier is through the purification module to send the indoor air purification directly to the indoor.The former is the outer loop, the latter is the inner loop; The important thing is that the fresh air system can pump oxygen into the house, reducing the concentration of carbon dioxide in the house by discharging it, while air purifiers can't.

Secondly, air purifiers can only improve the air quality of the space in which they are located, while the fresh air system can improve the air quality of the whole room.

Here, someone might ask, if a fresh air system was installed, would it be possible to replace the air purifier entirely?

The problem is that it needs to be treated differently. For example, a polite purifier is required for frequent smoking or meals, or family pets.

As you can see, the fresh air system is a necessity, while the air purifier is a backup.

As people concerned about their health as well as the influence of noise outdoor, residential environmental protection requirements of energy saving and human privacy protection, fresh air system is increasingly attracting the attention of consumers, believe in the fresh air system will like TV, washing machine will be into the thousands.

  

3. AMX Multi-function Air Purifying ventilator is coming

In order to deal with the difference between fresh air system and air purifier , AMX lunched a new type of air purifier , called AMX Multi-function Air Purifying ventilator. It can install with the ventilation system and purifier the air indoor and exhaust the polluted air indoor.

AMX company is located in Guangdong province and have the experience for improving air quality for more than 20 years.

We believe that the standard of fresh air is not only to reduce the PM2.5,

but making people feel like being in the forest.

It means that the air we breathe must be fresh, pure and rich with oxygen and negative ions,

which is also an important reason explains why people are so desire the nature environment.

  

In fact, there is no need to stay away from the city,

you could just stay at home, the fresh and pure air will be around you.

The ventilator is specially created for the people who love their family.

This is the original intention that our engineers and designers dedicated to create the Multi-function Air Purifying ventilator, A1 series. All their ideas and thoughts are base on the love for family. Based on the advanced AMX Multiflow aerodynamics technology, it can form three-dimensional circulation of the air flow to take care of every corner of the room.

Because of the love for family,

Our innovative engineers and designers developed this fresh air system with the air purifier,creating the Multi-function Air Purifying ventilator.

It has equipped with functions like fresh air, purification, negative ions, heating, intelligent detection and APP control, meanwhile it has a perfect appearance.

There are many different ways to show our loves to our family,

But our way is to create a truly effective Multi-function Air Purifying ventilator for family.

Enjoy fresh air, enjoy life. Everyone wants to live in the good environment and stay away from the polluted air. AMX ventilation can help you achieve this goal.

The simple design for the installation of ventilation system

AMX electric fan suppliers.The ventilation system is based on two systems, one is to deliver the fresh air from outdoor to indoor, the other is reject the polluted air from indoor to outdoor, this forms an air flow field within the sealed house, in order to refresh the air continuously.

The solution would be:

Use the high pressure air flow but with lower power consumption brushless motor to drive the centrifugal fan, this centrifugal fan will blow the fresh air from outdoor to indoor, the other centrifugal fan will also blow the polluted air from indoor to outdoor. During this process, the system will filter, antivirus, oxygenation and preheat the air, moreover, it will also recovery the heat.

Energy Recovery Ventilators

Many HVAC system designers have realized the benefits of using Energy Recovery Ventilation Fan in commercial and institutional buildings. However, as with many newly adopted technologies, questions of how best to apply this product are being raised. One application issue in particular is whether to apply an ERV as a stand alone unit on its own curb, or as a bolt-on accessory to a rooftop air conditioning unit.

What is the difference between the two systems? Although both systems require an exhaust air stream as an energy source to pre-condition outdoor air, the primary difference between the two systems is where the exhaust air is taken from. The drawings at the right illustrate this difference and help visualize how the ERVs tie into the HVAC ventilation system.

Some system designers may show a preference for the bolt-on ERV. This may be because they perceive that the installation cost will be lower, or they prefer having a single point of responsibility for the ERV/rooftop unit.

Combining outdoor air and exhaust air ventilation functions into a single unit help drive an important practice in good HVAC design-building ventilation balance. In layman’s terms: What goes in must come out. Traditionally, the outdoor air needs and the exhaust air needs were calculated in separate thought processes. The designer would specify the minimum outdoor air and exhaust air volumes required by code, but would stop short of comparing the totals to check the ventilation balance. Frequently, this led to over pressurized buildings where doorways were transformed into wind tunnels. In some cases, buildings became negatively pressurized and infiltration made indoor climate control difficult.

Exhaust fans and outdoor air fans are simultaneously energized so the building operates as it was designed. Separate controls, interlocks, and field coordination to maintain a balanced building are eliminated.

The AMX ERV system has many advantages over the bolt-on system. When considering the total ventilation system, the stand alone ERV offers higher efficiencies, provides a more reliable means of controlling ventilation, minimizes installation costs and enables energy recovery and economizer technologies to be combined for maximum energy savings

Boosting Air Conditioner & Ventilation System Efficiency

Change the air filter:

AMX electric fan suppliers 

Air filters perform the important function of removing particulates from the air circulating through your cooling system. When filters get clogged or dirty with accumulated particles, the efficiency and performance of your air conditioner drops significantly. Check the air filter at least monthly, or more often when you use the system more, if you have pets, or if you live in a very dusty environment. Replace the air filter as soon as it gets dirty.

Use fans to improve air circulation and cooling:

Install ceiling fans to increase the air circulation and cooling in particular rooms. You will be able to increase temperature settings on the thermostat by about four degrees and still retain excellent comfort with ceiling fan use. With the more comfortable temperatures in our area, there are days when the fans alone can bring sufficient cooling. By using ceiling fans, and relying less on the HVAC system, you will be able to reduce energy consumption and save more.

Reduce overall AC use:

When the outdoor air is cool enough or ventilation is adequate, shut off the air conditioner and enjoy the natural cooling. Consider installing a zoning system that lets you cool only those rooms and areas that are occupied. Ensure that doors and windows are closed when the air conditioner is in operation. Install a programmable thermostat that will let you control the function of the AC. Programmable models allow you to automatically reduce indoor cooling, for example, when you are not at home.

Schedule regular preventive maintenance:

Professional maintenance is the best way to ensure a long functional life and high levels of performance from your air conditioner. The technician will inspect the entire HVAC system and ductwork, make minor repairs, and adjust the system and its controls as necessary. The visit will also include a complete cleaning of the system to remove any clogs, dirt or debris. Preventive maintenance should be performed at least annually. If you rely extensively on your HVAC system throughout the year, or live in an area that where winters are harsh and summers bring very high temperatures, consider getting maintenance every six months, or sometime during fall and spring. Contact your trusted, local HVAC specialist for a maintenance appointment.

Talk about Air quality: base on two point

AMX air cooler manufacturer
1.How air affected in indoor, when the outdoor air is very bad.

2.What other reasons, the influence of indoor air quality?

First of all to get to the first question:
When it comes to indoor air, we must first understand the air quality standards inside what are focused on atmospheric composition: sulfur dioxide, nitrogen dioxide, carbon monoxide and ozone, PM10 and PM2.5, TSP, NOX, lead, benzopyrene and radon gas.

The impact of outdoor air particles on indoor concentrations was considered. Equilibrium mass balance models indicate that this is a function of the penetration P through the building envelope, the air exchange rate a, and the particle decay rate k. EPA’s PTEAM Study provided an estimate for k of 0.39 h(-1) for fine particles and 1.01 h(-1) for coarse particles. Two studies suggest that P = 1 for PM(10). Using these results, the fraction of outdoor air PM(2.5) and PM(10) particles found indoors at a given air exchange rate can be calculated. The protective effect of reducing air exchange rates during periods of high outdoor particle pollution can thus be quantified.

So Indoor outdoor influence degree to see whether the two size, one is the air flow rate, the other one is particle clearance.The removal of the indoor basically can be measured by observing, can also be enhanced through many physical means, PM2.5 slower, PM10 faster (gravity settling quickly), then control the air flow rate will further strengthen building block rate of air pollution.

How many have air volume still have when though the filter.

Use of personal-indoor-outdoor sulfur concentrations to estimate the infiltration factor and outdoor exposure factor for individual homes and persons

One goal of the study was to estimate the contribution of outdoor PM2.5 to indoor concentrations. This depends on the infiltration factor F-inf, the fraction of outdoor PM2.5 remaining airborne after penetrating indoors. After confirming with our measurements the findings of previous studies that sulfur has few indoor sources, we estimated an average F-inf for each house based on indoor/outdoor sulfur ratios. These estimates ranged from 0.26 to 0.87, with a median value of 0.55. Since these estimates apply only to particles of size similar to that of sulfur particles (0.06-0.5 mu m diameter), and since larger particles (0.5-2.5 mu m) have lower penetration rates and higher deposition rates, these estimates are likely to be higher than the true infiltration factors for PM2.5 as a whole. In summer when air conditioners were in use, the sulfur-based infiltration factor was at its lowest (averaging 0.50) for most homes, whereas the average F-inf for the other three seasons was 0.62-0.63, Using the daily estimated infiltration factor for each house,we calculated the contribution of outdoor PM2.5 to indoor air concentrations.

In addition to air conditioning, the following when decorating, essential items are always affects the indoor air quality:
Wood, wood itself is not toxic, but because of its process using urine aldehyde adhesive, so the form of formaldehyde pollution;Especially palm fiber board, density board and particieboard glue content is larger, which contains a lot of formaldehyde.(the finished board type furniture, cabinets using this board more)

Glue: the main components of the family is decorated in the use of glue for formaldehyde, use glue place such as metope grassroots emulsioni paint putty glue, paste board with white latex, the wallpaper glue paste wallpaper.100 – square – meter use glue in more than 100 kg, the bedroom of the national standard of glue content of 1 g/kg, so the bedroom decorate after basic 100 g formaldehyde, according to the three years preceding the standard conversion may exceed bid more than 3 times, almost covered the whole room make bridal chamber gas Chambers.The glue is decorated in possession of pollution sources pollution is the largest proportion.

Paint: because it contains a lot of heavy benzene, so people to paint the strongest perception;Family is decorated in the paint is applied topically, plus the volatilization of paint is quite fast, three days can volatilize harmful substances by more than 70%.So its not the biggest pollution source.It is recommended to use water-based paint replacement (add water dilute, oily paint with water or banana oil dilution) that day can be avoided.

Emulsioni paint, because use emulsioni paint area is very wide, lots of people generally think of emulsioni paint pollution is very heavy;Water-based latex paint is the main difference of other physical quality performance, within one day after brushing can volatilize harmful substances by more than 90% of them, so it can be usually ignored environmental performance indicators.

Cigarette: cigarette smoke gas and particle phase content contains thousands of chemical substances, including 60 has proved or suspected have carcinogenic effect to human body.Strictly, cigarette material includes chemicals, and combustion after the particulate matter.Journal of Tobacco Control once contrast cigarettes and the contribution rate of automotive diesel engine for PM, get the data as follows:

Diesel engine experiment background concentration: PM10 = 15, PM2.5 = 13, PM1 = 7
After an hour: PM10 = 44, PM2.5 = 31, PM1 = 13

Cigarette experimental background concentration: PM10 = 36, PM2.5 = 28, PM1 = 14
After an hour: PM10 = 343, PM2.5 = 319, PM1 = 168

So the indoor smoking bans how important it is.

Breathing: adult quiet breathing during a time of 6.4 seconds, with each inhalation and exhalation gas volume is about 500 ml, in the process of breathing:

Inhalation: 20.96% oxygen and 0.04% carbon dioxide and other gases by 79%
Exhale: 16.4% oxygen and 4.1% carbon dioxide and other gases by 79.5%

So, a breath of 20.5 ml of carbon dioxide, a year a total of 31536000 seconds, so one year exhaled carbon dioxide 101013.75 L.That is to say, 20 square meters bedroom sleep two people, not a night ventilation and ventilation condition is bad, can cause mild carbon dioxide poisoning after five hours.This is also a lot of people feel dizzy after waking up, the more sleep the more tired.

Almost 80 percent of air pollution involving soot that spreads from China over large areas of East Asia — impacting human health and fostering global warming — comes from city traffic and other forms of fossil-fuel combustion, such as home cooking with coal briquettes. That’s the conclusion of a study in ACS’ journal Environmental Science & Technology, which resolves long-standing questions about sources of air pollution responsible for Asia’s infamous atmospheric brown clouds.

Örjan Gustafsson and colleagues from China, South Korea and the United States point out in their study that nobody has been certain about the exact sources of soot, or “black carbon,” air pollution from the People’s Republic of China. People can inhale these tiny particles deep into the lungs, and estimates implicate soot with 500,000 premature deaths annually in China alone. Black carbon in the atmosphere also absorbs sunlight, and scientists think it is second only to carbon dioxide as a factor in global warming. Gustafsson and his team set out to identify the exact sources of black carbon in China.

They describe using a powerful carbon-14 identification method to trace fully four-fifths of the black carbon emitted in China to incomplete combustion of fossil fuel such as coal briquettes used in home cookstoves and automobile and truck exhaust. “To mitigate near-term climate effects and improve air quality in East Asia, activities such as residential coal combustion and city traffic should be targeted,” they conclude.

How to solve or improve indoor air quality?

Install some exhaust fan inside your house;

1. Install fresh air system, such as our ER (heat exchanger), AJH (Purifying box), DPT-PM ( purifying blower), BPT( ceiling mounted ventilation fan), APC (window mounted ventilation fan), DPT(quiet cabinet fan), and some outlet.
2. Add more air purifier, and so on.

How to maintain the Ventilation System?

The AMX ventilation fan system has a strong effect on the air quality after the interior decoration.Twenty-four hours potent exchange between indoor and outdoor air, can exhaust the interiors gas such as formaldehyde harmful ingredients to outdoor in a short period of time, put the fresh air to the indoor and accelerated air self-purification ability of bridal chamber, let consumer live into the new house at an early date.The AMX fresh air system also has a keen humidifying effect.As we all know, whether winter or summer, long time in indoor air conditioning, the room will become dry and dehydrated, easy to cause a fire.However, the fresh air system has the constant temperature

Fresh air system is an energy saving, healthy, and comfortable ventilation system. It can filter oxygen-enriched air to the indoor air, at the same time, can collect indoor pollution air and discharging it outdoor. Therefore, the ventilation system can real-time control the indoor air pollution and replace indoor and outdoor air during the 24 hours. Filters of ventilation fan can effectively isolate floating in outdoor air pollutants and fog haze, viruses, bacteria, mold, pollen and other harmful substances.

But when we use in a long time. the user is not in a timely manner to replace and cleaning the filter ,the outlet and the filter mesh adsorption the dust in the air, the mosquito, indoor foul gas through the outlet to the outside, outlet adsorption of dust which will inevitably make the discharge to the outdoor air not thoroughly.Besides, some residual foul gas stays indoors which will do harm to the indoor people’s health.Long-term in the past, the usual effect of the fresh air system will seriously decline, even may produce secondary pollution, therefore, fresh air system is necessary for regular maintenance.

If we do not maintain the ventilation system ,the machine will appear the following situation:

1) accumulation of dust inside the filter, air volume is smaller, but power consumption has increased.

2) PM2.5 purification efficiency decreased, from outdoor the PM2.5 concentration is higher and higher, because the screen causes purification efficiency decreases.

3) the noise is more and more big. The wish to turn off to sleep at night.

4) control part is easy to failure because components of formation are affected with damp 5) 5) heat exchange efficiency drops, fresh air inside is more and more hot in summer and the cold air in winter.

6) pipeline not to clean all the year round, fresh air system wall will be deposited, the risk of breeding bacteria causes secondary pollution.

So how to maintain the new air system properly?

(1)Outlet and filter cleaning and screen cleaning

When the extra ventilation system working, the outlet of the vents will absorb the dust of a large amount of air because of static electricity. Dust can cause bacteria and affect beauty and health.A professional central fresh air system should be regularly clean air outlet (generally for every 6 months), when cleaning outlet needs special cleaning agents, and filter, outlet and filter dust clean, in order to avoid jams, affect the supply efficiency.

Check air speed and main wiring

Due to the decrease of air duct dust and the sealing performance of the pipes, it will lead to uneven air volume and poor new air effect.It is recommended that the professional staff regularly (6 months) checks the system and adjusts the air volume, eliminates the hidden trouble and guarantees the new air effect.New air machine wiring inspection. If the new fan terminal is used for a long time, a large amount of dust may be accumulated and the wiring will be loosened due to the vibration of the original fan, resulting in a safety hazard.The central new aid system needs to be regularly (12 months) to check the wiring of the new fan and solve the safety problems in a timely manner.

Check control panel and piping air tightness

New risk control system of switch check: a new system of risk control panel for more precision electrical components, use for a long time due to electrostatic adsorption gathered dust or moisture, easy to cause the failure control panel or element damage, using the inconvenience caused.Air tight inspection of the new air duct: long term use of new fan vibration, etc., can easily lead to the cracking of the new air pipe joints and leakage of air and other phenomena, resulting in the decrease of the usual effect.It is necessary for professional personnel to check the connection of the air duct regularly, repair and improve the effect of new air.

In addition to the performance of the product itself, the energy consumption of the fresh air system is also affected by the late maintenance, which can reduce energy consumption to a certain extent.

Whether it is a new fresh air system without pipes or a fresh new central air system for piping, if the outlet is blocked, the air volume of the machine will be greatly discounted.

In the process of the household knew fresh air system, the problems that arise are unavoidable. We should pay attention to the maintenance and maintenance when, we use them, which is also a college question.Need careful, patient, and superior learning ability, so in order to make it efficient and smooth running, prolong service life, and to provide clean air for our room, to ensure your family’s health.

AMX is a professional manufacturer for fresh air system. And now we will have the new product,which is the wall -mounted ventilation air purifier and integrated ceiling bathroom heater.We find our own R&D department, and can accept all OEM & ODM inquiries.

How to effectively decrease the noise of ventilation system.

During the installation of the ventilation fan system, we often face this situation which is after the installation, the noise and air flow in bedroom and study room are kind of high, for those elderly people or those people who are very sensitive to noise, this will affect their sleep badly. The worse thing is, even you know the noise is unbearable for the ventilation system, but you will still need to open it, so this becomes a very intractable issue, so how to solve the noise from the ventilation system becomes a serious topic, but, eventually, we found the solution.

First, to chose the right and suitable ventilation products.

The ventilation system is using a persistent ventilation mode, the structure inside the ventilation product and the motor selection will ensure the persistent service time, in this case, it can continuously ventilating the air, although it might can’t be the same effects for short terms ventilating comparing with opening the window directly, but this continuous ventilation can reduce the polluted air from outside and can maintain the temperature inside the house. So, to choose the right ventilator, it must be according to the national regulations, no need for a very large air flow, in this case the noise will be lower, however, you could choose the super silent AMX brand ventilators, then you can solve the noise problem once for all, and most importantly, the air flow is also very astonishing. Also, as for AMX Fan, we have been in this business for more than 20 years, what we can provide is not just the products, but also the complete designs and solutions for your house, and everything could be customized.

Second, the rational design for air pipes.

When designing the ventilation systems, the air pipes overall arrangement should be considered in the first place, then the balance between air pressure and air speed from every air outlets, if the air pressure difference is huge, to adjust the air outlet rigidly will only rise the noise, especially in bedroom and study room, or if it is too close to the main ventilator, we suggest to choose circumvent design or sound-muffling pipe to connect the joint.

Third, suitable remediation after installation.

If still can’t sole the noise problem after the ventilation system is installed, and the pipeline is also adjusted, then we will have to work out some remediation, such as.

1.To change the hardware hanging of the main ventilator to spring hanging, to decrease the noise from the main ventilator as lower as we can.

3、To coat another silencer cotton at the ceiling surface, this will decrease the noise echo from the installation area between main ventilator and the ceiling, this will decrease the resonance between them also.

4、To add some silencer cotton at the turning or the air inlets, to add some windage in order to decrease the air flow, and obstruct the noise.

5、To change the pipe material into aluminum flexible pipe in the section with more noise, add the length of the pipe appropriately, and to add some windage at the turning, this will effectively decrease the noise.

With the help of these process, products selection, design and remediation, we could adjust the noise within a normal standard, or if you have more efficient way to decrease the noise, you are most welcomed to share with us.
