Xuzhou 圣尔达 Refrigeration Electrical Services Ltd First, the basic concept of an air conditioner, air conditioning, air conditioner stands for, generally refers to in a particular space temperature, humidity, cleanliness and adjust the flow rate, and meet the standards process requirements and can meet the needs of human comfort appliances. 2, with three basic functions: cooling, heating, dehumidifying 3, ambient temperature heating and type of -7 ℃ -43 ℃ (National Standards) 4, refrigeration 18 ℃ (indoor) ~ 43 ℃ (outdoor), dehumidification 18 ℃ below (room temperature) 5, air conditioning noise national standards: cooling capacity 2500W-4500W machine ≤48 dB, outside the machine ≤58 dB; cooling capacity 4500W-7500W machine ≤52 dB, outside the machine ≤62 dB. 6, when most of the air conditioning heat pump heating system, it has the advantage of high energy efficiency, is also using the auxiliary heating function, an increase in indoor heating pipe, it has the advantage of fast heating at low temperatures, but the disadvantage is that the electricity consumption higher when purchasing power electric heating air conditioning to take into account his meter capacity and 220V or 380V. Xuzhou Sheng Erda Refrigeration Electrical Services Limited five, the indoor temperature does not drop down. Be the first to try his hand in the air conditioner and the air temperature has an exception, if normal, then the air conditioner without failure. The cause may be due to many people indoors, excessive heat, Xuzhou brand air conditioning prices, the higher the outdoor temperature air moves in Xuzhou, Xuzhou room windows not shutting fluoride air conditioning, curtains did not pull the strict air-conditioning, heat source near the air conditioning, the room door switches and frequent. Six cooling operation, the indoor unit and poor ventilation, the wind is not too cold. New air conditioners generally use three filters, namely, nylon mesh, electrostatic filter layer, activated carbon filter layer, high filtration efficiency, strong purification ability to capture dust particles small diameter air, but the filter cleaning cycle shorter. If not cleaned, there will be poor access when the mesh is blocked, slow cooling air flow to reduce the phenomenon. Xuzhou central air conditioning installation _ Sheng Erda refrigeration (certified) _ Air conditioning is provided by Xuzhou 圣尔达 Refrigeration Electrical Services Limited. Xuzhou Sheng Erda Refrigeration Electrical Services Limited (xzktw.com) Xuzhou, Jiangsu, heat, refrigeration and air conditioning equipment leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customers needs.
