Xuzhou 圣尔达 Refrigeration Electrical Services Limited (a) performance parameters: ☆ refrigeration air conditioner for cooling operation, the sum of the heat removed from the unit of time in a confined space, room or area, is a measure of the performance of the main indicators of air conditioning one, in units of watts (W) or kilowatts (KW). ☆ air conditioner cooling power consumption make Xuzhou price of second-hand air conditioning cooling operation, the total power consumed per unit: W. ☆ energy efficiency ratio (EER) at rated conditions and specified conditions, air conditioner for cooling operation when used with air conditioning, cooling capacity and the effective input power ratio, is one of the key performance indicators to measure the air conditioning, the value is expressed in W / W. ☆ heat capacity heat pump air conditioner heating operation, the unit of time into the confined space, the room is the sum of the heat within the region or, one of the main indicators to measure the performance of air conditioning, in units of watts (W) or kilowatts (KW) . ☆ coefficient of performance (COP) at rated conditions (high temperature) and specified conditions, air conditioner heat pump heating operation, the heat capacity and the effective input power ratio, its value is expressed in W / W. ☆ circulating air volume air conditioner vent door is completely closed the door and exhaust and cooling operation at rated conditions, confined space within the unit time, room or area into the wind, unit: m3 / h. Xuzhou 圣尔达 Refrigeration Electrical Services Limited 1. What is energy-saving air? The concept of energy-saving air-conditioning energy efficiency rating system by the national enforcement leads. According to the national energy efficiency requirements identity management approach, the fixed-frequency air safety level of energy efficiency energy efficiency rating is divided into five, namely 1,2,3,4,5 level, meaning each level as follows: 1) a future market for the main push for energy efficiency 2) 2 for the energy level, energy-saving products on behalf threshold (the minimum life cycle cost) Xuzhou hand air conditioning accessories, can apply for energy-saving product certification 3) two representatives of the average 4) 3,4,5-class energy efficiency is the lowest value products, but also out of the product (except inverter air conditioner) Therefore, the above two are known as energy-saving air-conditioning, air-conditioned and non air-conditioned two more in 2010 have all been eliminated. Used Xuzhou refrigeration, air conditioning repair _ Sheng Erda (certified) _ Used air conditioning provided by Xuzhou 圣尔达 Refrigeration Electrical Services Limited.
