Description
Technical field
The utility model relates to a kind of new full heat exchange purifier of wind, and the utility model is applicable to the full heat exchange facility of all new wind.
Background technology
In recent years, people have been not limited only to temperature, humidity, wind speed etc. and comfortable relevant condition to the requirement of indoor air environment, and rise to for pernicious gas (CO in room air
2, VOCs etc.) attention of concentration, dust etc. and the closely-related IAQ of health (IAQ:Indoor Air Quality).Comfortable and health becomes the two principal themes that modern air conditioning is pursued.But due to improving constantly of building energy conservation requirement, building level, the air-tightness of building is become better and better.Therefore,, from health and healthy requirement, must there be a certain amount of fresh-air ventilation in room, improves the integrated quality of air-conditioning room air to guarantee increasing to greatest extent new wind.According to GB " IAQ standard " GB/T18883-2002, for house, office building, its resh air requirement should be not less than 30m
3/ h people.And for the intensive public building of some personnel or the indoor industrial building that has pollution sources, its rate of ventilation can be up to 6h-1.Larger ventilation volume, will inevitably cause larger heat (cold) loss of energy, causes air conditioner load to increase.So, ensure that IAQ and air conditioner energy saving form conflict, solving this contradiction is the new problem that air-conditioning man author faces.Total-heat exchanger can reclaim the airborne sensible heat of air conditioning system return air and latent heat simultaneously, and as the energy-saving equipment of building air-conditioner ventilation air interchange system, its penetration and promotion more and more comes into one's own.
After precipitate from one, mainly to pass through air route infection SARS outburst; make people have to pay much attention to the integrated quality of air-conditioning room air; although people have recognized the crisis that energy shortage brings, the environmental requirement that people pursue healthiness can not be stopped.Thereby how just can accomplish that saving to greatest extent energy resource consumption improves rate of heat exchange when increasing resh air requirement in air-conditioning system, avoid cross pollution is the primary study direction of industry simultaneously.
The main cause of at present traditional total-heat exchanger generation cross pollution has two:
(1) when total-heat exchanger enters Xin Fengqu by return air district, a fraction of return air can be entrained to Xin Fengqu, cause cross pollution to occur;
(2) hygroscopic material that existing total-heat exchanger uses is porous adsorbent.Because adsorbent micropore not only has suction-operated to airborne steam, to having taste, pernicious gas, volatile organic matter (VOCs) etc. also has suction-operated.Even be considered to the places such as taste, the infrequent office building of pernicious gas, hotel, senior house building, because various construction materials, interior decoration material and furniture etc. can discharge lentamente as the volatile organic matter such as formaldehyde, acetone, or due to smoking, perspiring etc. produce the gas such as ammonia, nicotine.When these harmful unpleasant gases pass through total-heat exchanger along with return air, understand some and adsorbed by porous adsorbent, and be accumulated in total-heat exchanger.When total-heat exchanger (more than at least 1 year) after longer service time, when humidity, the temperature etc. that runs into outdoor air has larger abrupt change, what these were accumulated has taste, pernicious gas to discharge from heat exchanger runner, and the new wind of quilt brings back to indoor, occurs so-called cross pollution.
