摘要： Disclosed is a cooling and heating air conditioner capable of performing heating more stably, preventing frost formation on coils of an outdoor unit even at subzero temperature in winter by using first and second heat exchangers and an auxiliary expansion valve. The air conditioner according to the present invention comprises an electronic control valve opened when the outside temperature is less than a preset value, a first heat exchanger performing heat exchange between high temperature liquid coolant and coolant passed through the outdoor unit and an auxiliary expansion valve, and a second heat exchanger disposed in front of the outdoor unit to induct thereinto the high temperature coolant. Since the second heat exchanger heats up the outside air through heat exchange before supplying the air to the outdoor unit, evaporation of the coolant can be stably performed in the outdoor unit, while preventing frost formation. Accordingly, heating can be performed constantly.
摘要翻译：公开了一种能够更加稳定地进行加热的冷却和加热空气调节器，即使在第二和第二热交换器和辅助膨胀阀中，即使在冬季的零下温度也能防止户外单元的线圈上的结霜。根据本发明的空调器包括当外部温度低于预设值时打开的电子控制阀，在高温液体冷却剂和通过室外单元的冷却剂之间进行热交换的第一热交换器和辅助膨胀阀，以及第二热交换器，其设置在室外单元的前面，以将高温冷却剂引入其中。由于第二热交换器在向室外机供给空气之前通过热交换来加热外部空气，因此可以在室外单元中稳定地进行冷却剂的蒸发，同时防止结霜。因此，可以不间断地进行加热。
