The health degree in border.The quality of indoor air quality, has a significant impact to people’s lives and health, especially in recent years, greatly
Gas pollution aggravation, causes the air that people depend on for existence to be contaminated, therefore, it is necessary to be carried out to being sent into indoor fresh air
Filter, purified treatment, meanwhile, to indoor pollutant concentration (such as:CO2) controlled, it is strong with the health and body that meet people
Health demand.
As the improvement of people's living standards, building energy consumption also steeply rises.According to statistics, China's building energy consumption accounts for about the whole nation
The 20% of total energy consumption, if adding architecture construction energy consumption, the construction in whole building field and operation energy consumption account for the whole society
Primary energy consumption sum-rate is up to 36%.Therefore, building energy conservation is particularly important.Outdoor fresh air is handled, to reach
Indoor temperature and humidity requirement, energy consumption is very big, accounts for about the 20-30% of air conditioning energy consumption, therefore, is carried out to outdoor fresh air using building air draft
Precooling/the pre-heat treatment, can be energy saving, reaches good energy-saving effect.
Current fresh air pretreatment device is broadly divided into two kinds, and one is full heat recovery device, another kind is Exposure degree
Device.The former heat recovery efficiency is relatively high, still, there is new, air draft cross contamination risk;The latter mainly uses the tributary
Heat exchange method based on heat exchange, although being avoided that new, air draft cross contamination danger, heat recovery efficiency is relatively low.
