What is the role of central air conditioning? 1. Functional cooling in the design and manufacture of air conditioners, generally allows to control the temperature between 16 ~ 32 ℃. When should the temperature setting is too low, on the one hand an unnecessary power consumption, on the other hand cause the indoor and outdoor temperature difference is too large, it is out of the room can not quickly adjust to temperature changes, susceptible to colds. 2. The dehumidifying air-conditioning with the air conditioner in the dehumidification cooling process. People feel comfortable ambient relative humidity should be around 40 to 60% central air-conditioning manufacturers, the relative humidity is too large as more than 90%, even if the temperature in the comfort range, people still feel bad when. 3. The heat pump heating and electric air conditioner has a heating function. Heating capacity with the outdoor ambient temperature decreases progressively smaller central air conditioning installation, can hardly meet the heating requirements if the temperature at -5 ℃. 4. Clean air in the air with a certain amount of harmful gases such as NH3, SO2, etc., and a variety of sweat, body odor and the bathroom smelly odor and so on. Air conditioner purification methods are: renewal wind, filtration, or the use of activated carbon adsorption and absorption photocatalyst. A, renewal wind: the use of the indoor fan system moist air to outdoor volleyball, indoor a certain degree of negative pressure, fresh air into the room from all around the door, Chuang Feng, improve indoor air quality. B, photocatalyst:? In the light irradiation can be regenerated, adsorption (income) of ammonia, nicotine, acetic acid, hydrogen sulfide and other harmful substances freed, re-use central air-conditioning is installed and by whom the home central air conditioning installation It is important central air conditioning, central air saying "one-third quality, seven installation" and air-conditioning installation points each are different brands of central air conditioning Which is good, so try to make the brand select resellers and installation team to installation, because they are trained in various brands of specialized training, installation capacity by brand manufacturers recognized.
