Air conditioning is indispensable in our lives Electric central air-conditioning manufacturers, we often there are some errors in the use of air conditioning during use: Myth one: the refrigerant needs to be changed once a year Myth: air conditioning for a long time do not matter Myth: air-conditioned room no need to replace the air Myth: just washed clean air filter 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%, when the relative humidity is too large, such as central air conditioning installed in more than 90%, central air conditioning production even if the temperature in the comfort zone, people still feel poor. 3. The heat pump heating and electric air conditioner has a heating function. Heating capacity with the outdoor ambient temperature decreases progressively smaller, 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 offer, Xi'an Hao Electrical and Mechanical Services (certification), Tongchuan central air conditioning provided by the Xi'an Hao Electrical and Mechanical Technology Limited.
