20140290294 | AIR HEATING UNIT OF THE AIR-CONDITIONING - The present invention relates to an air heating unit of the air-conditioning including a compressor, a thermal compensation device and an air cooled condenser connected sequentially with one another by pipeline to define a refrigeration cycle. A high-temperature gaseous refrigerant flowing in inner and outer tubes of the thermal compensation device performs transfers heat with an intermediate-temperature liquid refrigerant flowing in mid tube, so that temperature of a liquid refrigerant flowing in a capillary gap between mid and inner tubes is increased to achieve liquid expand and flow restrained effects. The capillary gap can block bubbles of super heat from entering and suppress the liquid refrigerant from flowing through. Thus, a limited amount of liquid refrigerant can be sucked into the compressor at a low pressure without having lubricating oil to be turned cold.
