在冬季气温较低的日子里,空调的制热效果往往很差,尤其早晨甚至连开都开不起来。这是因为空调制热的原理是利用热泵将室外环境中的热量传入室内的。一般情况下,当气温低于零下5℃,制热效果就开始明显变差。气温越低,制热效果则越差。当冬季室外温度过低时,室外机就很难再从室外空气里吸取热量传导到室内,这时空调即使能够运转,制 In low winter temperatures, air conditioners often have poor heating effects, especially in the morning and even in the open. This is because the principle of air conditioning heating is the use of heat pump to the heat in the outdoor environment into the room. Under normal circumstances, when the temperature below minus 5 ℃, the heating effect began to significantly worse. The lower the temperature, the worse the heating effect. When the winter outdoor temperature is too low, the outdoor unit is difficult to draw heat from the outdoor air conduction to the room, then even if the air conditioning can run, the system
