Energy-saving air-conditioner, namely evaporative air conditioners. Energy-saving air-conditioner is absorbed in the air quantity of heat to evaporate cooling purposes, according to the natural phenomena of ＂water evaporation efficiency＂ this principle: when the hot air through practical heat water evaporation area of 100 times, when the damp curtain of hot air will be absorbed, so as to realize the air cooling process. With traditional compressor air conditioning in the working principle and structure of different, in the cooling speed, health and economic, environmental protection, installation and maintenance etc have prominent advantages. Energy-saving air-conditioner is absorbed in the air quantity of heat to evaporate cooling purposes, according to the natural phenomena of ＂water evaporation efficiency＂ this principle: when the hot air through practical heat water evaporation area of 100 times, when the damp curtain of hot air will be absorbed, so as to realize the process of cooling air conditioning, compared with the traditional maximum characteristic is not compressor, so he energy-saving, environmental protection, and a fresh, clean air, for you to create a more healthy and comfortable working environment. Compared with the conventional air conditioning, the operation mode, the conventional air conditioning is required to keep indoor temperature closed the door, such cause indoor air quality greatly reduced, stale air, smelly, make the person produces headache, nausea and so-called ＂KongDiaoBing＂, for some harmful gas workshop, if not necessary ventilation equipment, can cause poisoning, and energy efficient air conditioning can solve the problems in the operation is needed, the open door window, air conditioning, hot air continuously into excluded, always keep the air fresh, natural environment. The traditional investment need only half of the air conditioning compressor, middle power operation needs only traditional air-conditioning [/ b] 1/8 [/ b] [/ b] 1-10 [/ b], maintenance cost is low. Energy-saving [/ b] [/ b] above 85% cooling rapidly. Directional positions, more economical and practical. No freon, low noise, vibration, no heat. But for cooling equipment, equipment operation is more stable, prolong service life. For staff to create a good environment, saving production cost, improve enterprise competitiveness.
