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

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.

SPOTLIGHT ON INDOOR AIR QUALITY PRODUCTS

A tightly-sealed home prevents excess strain on your HVAC system, but such a sealed environment can negatively impact your indoor air quality. The quality of your indoor air affects not only the function and efficiency of your HVAC system, but your health and comfort while at home as well. Central heating and cooling systems utilize an air filter to screen particles out of incoming air, such as dust, pollen, animal dander, and other airborne pollutants. However, these filters are only the most basic tool in your arsenal to fight poor-quality indoor air. There are a number of additional air quality products you can add to your home’s HVAC system for cleaner, healthier indoor air throughout the year.

ElectronicAir Cleaners

Electronic air cleaners are designed to fit into your HVAC system as a permanent addition. These air cleaners function using the same basic principles as a standard air filter to screen particles from the air, but utilize one added feature: electrostatic charge. By creating an electrostatic charge and running it across its filter medium, electronic air cleaners attract dirt, dust, and other charged particulates to the filter, where they effectively become stuck to the filter medium. This medium is reusable—every so often, you’ll need to remove the filter medium and wash it, then you can simply replace it and restart your electronic air cleaner for continued operation.

UV Lamps

Ultraviolet (UV) light is comprised of energetic photons. Since 1903, scientists have known that exposing bacteria and viruses to concentrated UV light will kill them, and UV lights have been used to sanitize hospital and health care facility air for decades. Today, you can gain the same benefits at home by installing a UV lamp in your HVAC system—all that’s required is a small hole cut in your duct work above the air handler, through which the lamp is fitted so it can illuminate air as it moves through your HVAC system and into your duct work for distribution to the living areas of your home. UV lamp maintenance is minimal, with most bulbs lasting an average of one full year before requiring replacement.

Humidifiers

Not all indoor air quality products focus on cleansing your indoor air. While clean air is important, factors such as humidity can also affect your health and comfort, as well as the longevity of your belongings and even the finishes in your home. Air that is too dry can cause static electricity to build up, as well as irritate the eyes, nose, mouth, and throat. Dry air can also damage your home’s finishes over time, causing them to crack or peel. Whole-home humidifiers are installed as part of your home’s heating system, adding humidity to the air after your furnace heats it. During the summer, you should turn off the power and water to your humidifier to keep it in good shape. Additionally, the humidifier’s evaporative pad should be changed periodically to ensure it stays clean and mold-free to keep your home’s air clean as well.

Your Columbus-area HVAC service can help you make the right choice when it comes to purchasing, installing, and maintaining products to improve your indoor air quality. Please look through our websiteto learn more about the products and services we offer, or take a look at our blog for more home heating, cooling, and air quality tips.

What is Heat Exchanger

When the Heat Exchanger is running, vitiated air from indoor and fresh air from outdoor goes through the heat exchanger to exchange the temperature and humidity,so as to achieve ventilation and keep indoor temperature and humidity stability.

When the heat exchanger running in summer, fresh air gets the cooling capacity from vitiated air, and the temperature was lowered and dry.

When the heat exchanger running in winter, fresh air gets the heating capacity from vitiated air, and the temperature increased and humidity.

Suggestion:

1. We have 3 kind of duct size: 100/150/200 mm of fresh air Inlet and vitiated air outlet, please confirm the duct size according to the model No. To keep low noise and keep the air volume, static pressure, please make the branch duct size smaller.

2. In order to prevent the condensed water please add some thermal barrier connect to the air inlet and outlet duct.

3. Try to reduce the number of the connector, to avoid duct sharp turns, twists, turns and variable diameter, etc.

4. During duct connection process, please keep the duct sealed to avoid air leakage.

5.It should be more than 1 meter between fresh air inlet and vitiated air outlet of outdoor.

6. Do not use the wall hole as the transition joins.

7. You can choose our company other ventilation fan to work for your whole set of house. Such as BPT ceiling mounted ventilation fan, AJH Purifier box, DPT quiet cabinet fan, etc.
