Description

Constant temperature and humidity clean air conditioner energy conserving system
Technical field
The present invention relates to constant temperature and humidity clean air conditioner energy conserving system.
Background technology
Current making rapid progress along with science and technology, especially the sci-tech product such as military affairs, space flight, aviation, electronics, biomedicine is produced, processing all be unable to do without constant-temperature constant-humidity air-conditioner, air-conditioning system workshop, toilet, its lustration class is all between 100 grades of (ISO5)-10000 grade (ISO7), it is 22 ℃ ± 2 ℃ that temperature is controlled, and relative humidity controls 55% ± 5%.Because constant-temperature constant-humidity air-conditioner, toilet's air conditioning energy consumption are very surprising, therefore the energy-conservation of toilet can not be ignored.Its energy consumption is 10-15 times of common air-conditioning workshop.Take 12 " it is example that LCD produces, and Energy Consumption in China is higher by 40% than the U.S., (U.S. 1.28-1.63kw/m2 toilet,, Chinese 1.68-2.13 kw/m2 toilet).The design of traditional constant temperature and humidity clean air conditioner unit generally all adopts surface cooler by the dehumidifying that cools after return air and new wind mixing, reach dew-point temperature following (surface cooler leaving air temp is conventionally at 8-12 ℃), because temperature control in workshop is 22 ℃ ± 2 ℃, therefore have to, adopt electric heater (or steam, hot water) that surface cooler air-out dew-point temperature is heated to ventilation state point and blow, after mixing with the air in room, reach workshop moisture temperature requirement.In the process of this air-treatment, unavoidably there is the process of the energy offset of a larger cooling, intensification, i.e. the surface cooler cooling heater antagonism of heating, has wasted a large amount of energy in vain, and this is to perplex HVAC industry problem for many years.AHU air-conditioning is after once indoor return air C mixes with new wind A, enters the master meter cooler S dehumidifying (be dew-point temperature below) that cools, and airborne moisture is condensed outside discharge chamber, thereby reaches effect on moisture extraction.But because air is after master meter cooler S is cooling, air themperature is generally reduced to below 12 ℃, then it is temperature required through electric heater T, to be heated to workshop, and by blower fan, I sends in clean room.Therefore this traditional constant temperature and humidity, toilet's air conditioning energy consumption are very surprising.
