The ventilation system usually is opened 24 hours a day with active dweller inside the house, a lot of people will think that this will cost a lot of electricity, but, actually, if we don’t consider the windage and windage loss, the ventilation system is just like one ventilation fan with a bit large power, usually for a 120 square meters ordinary homes, the ventilation system will not larger than 100w, power consumption will be 2 degrees for 24 hours, daily average cost will be only 1 RMB.
The maintenance cost for ventilation system.
The first thing that need to change is the filter, this is the main part and the most important part, usually the filter is separate with electrostatic precipitation type and physical filtration type.
We don’t need to change electrostatic precipitation filter, just regular maintenance, and this won’t cost that much. But, consider the effect of the electrostatic precipitation filter, it’s not that efficient actually, and with the electrostatic effect, the oxygen will turns to ozone, this will harm peoples health.
The physical filtration filter usually have three different levels, pre-filter, activated carbon filter and high efficient filter, the pre-filter will mainly decrease the large size substance such as dust, hair and other substances. The activated carbon filter will mainly adsorb the hazardous substance in air. The high efficient filter is accurately decrease the germs, virus, PM2.5 and PM0.3, this is why the cost for high efficient filter is also kind of expensive.
Usually the high efficient filter can use the filter with H13 and HEPA type, this can decrease 99.97% of the PM0.3, it usually cost 200-300RMB per piece, in winter, it will need to change more frequently, but, averagely, to change the filter for ventilation system, it usually won’t cost over 1000 RMB per year.
In China, most of the area belongs to temperate climate, so we must consider the installation of the heat exchanger and replacement of its filter. In the market, the filter usually has two types, aluminum made heat exchange core and paper made heat exchange core, the aluminum made heat exchange core can be cleaned directly, the paper made heat exchange core can’t be cleaned, but only to exchange it, usually 2-3 years, relatively speaking the cost for heat exchange core is not that expensive. If it is ductless ventilation system, the maintenance cost will be lesser.
But the maintenance is very necessary, because this will remains the high efficient of the ventilation system, and this will also enlarge its service life, as for the ventilation system, beside the high efficient function, nothing is more important than the service life, so since you have already spend some money on the ventilation system, you may as well paying some attentions on the maintenance, if its function can’t be ensured, then why bother purchase it anyway.
