Abstract

The invention relates to an energy-saving quick defroster comprising a high-pressure gas bypass unit and a defrosting compressor unit. The high-pressure gas bypass unit and the defrosting compressor unit are parallelly connected with the high-pressure side of a refrigerating system and an evaporator. By the use of the energy-saving quick defroster, solved are such problems that during defrosting the refrigerating and heating air conditioner unit takes long time of defrosting, the evaporator side temperature changes sharply and energy consumption is high. Compared with the prior art, the energy-saving quick defroster is energy efficient, high in defrosting speed, low in temperature fluctuation and significant to solving the haze problem.

Description

technical field [0001] The invention relates to the technical field of heat exchange, in particular to a rapid defrosting device which utilizes the saturation property of a refrigerant to shorten the defrosting time of an evaporator of a refrigeration and air-conditioning system, has small temperature fluctuations on the side of the evaporator, and has low energy consumption. Background technique [0002] We know that due to the low thermal conductivity and high thermal resistance of the frost layer, if the evaporator cannot be removed in time after the frost is formed, the energy consumption of the refrigeration system will increase by at least 10-15%. Therefore, after the evaporator of the refrigeration system is frosted, a reasonable defrosting method is very important. [0003] Similarly, for air-source heat pump air-conditioning systems, especially in areas north of the Yangtze River Basin in my country, the ambient humidity is relatively high in winter, and the evapora...
