建国以来我国空气调节事业获得了很大的发展,今后必将得到更大的发展。但是空调是一耗能较多的领域,例如,对旅馆空调,每平方米客房面积的总冷负荷约为100千卡/时;而对工业空调,它耗能更多,比如对有净化要求的空调系统,每平方米空调面积的总冷负荷可高达500～600千卡/时。所以在民用空调中,它的耗电量通常成为整个建筑物的主要耗电量;而在工业空调中,空调耗电量一般也在整个生产耗电量中占相当的比重,有时甚至占一半以
Since the founding of our country, the air-conditioning business has gained great development and will surely get even greater development in the future. However, air-conditioning is a more energy-consuming areas, for example, the hotel air-conditioning, the total cooling load per square meter of room area is about 100 kcal /; and for industrial air conditioning, it consumes more energy, Air conditioning system, the total cooling load per square meter area of air conditioning up to 500 ~ 600 kcal / h. Therefore, in residential air conditioners, its power consumption usually becomes the main power consumption of the whole building. In industrial air conditioners, the power consumption of air conditioners generally accounts for a considerable proportion of the total power consumption of production, sometimes even half To
