Description

Technical Field

[0001] The utility model relates to the technical field of heat pump defrosting, in particular to a jumping defrosting device. Background Art

[0002] When the heat pump or air conditioner enters the defrost state, the evaporator fan stops working, and the high-temperature and high-pressure refrigerant from the compressor enters the evaporator, causing the frost layer to gradually dissolve. After the frost on the upper part of the evaporator is melted, the temperature will gradually rise, and the condensed water will flow from top to bottom. The lower evaporator will take away a large amount of heat due to the condensed water, causing the temperature at the bottom of the evaporator to rise slowly, resulting in uneven temperature distribution on the evaporator. Since the temperature at the bottom of the evaporator is difficult to rise, the defrost effect is affected. Utility Model Content
