Abstract

The present invention relates to a heat pump system having a waste heat recovery structure with 2nd evaporation and, more specifically, to a heat pump system having a waste heat recovery using a secondary evaporator capable of recovering waste heat discharged from a heat pump cycle to the outside using a primary evaporator, and passing a refrigerant, overheated by the recovered heat, through a secondary evaporator to radiate heat, thus providing a function for supplying initially induced air to a condenser in a pre-heated status and saving operational energy and preventing an overload of a compressor, in proportion to the heat energy reused in the condenser. The heat pump system comprises a compressor (110), a condenser (120), an expansion valve (130), a primary evaporator (140) and a secondary evaporator (150). The condenser (120) provides a function for supplying heated air, and the secondary evaporator (150) is positioned at the front end of the condenser (120) to preheat the initially induced air.

Description

technical field [0001] The present invention relates to a heat pump system having a structure for recovering waste heat through two-stage evaporators, and more specifically, relates to recovering waste heat discharged to the outside in a heat pump cycle by using a first-stage evaporator, and then turning it into a superheated steam state by the recovered heat The refrigerant passes through the second-stage evaporator and releases heat, thereby preheating the initially input air and providing air in a preheated state to the condenser. By providing this function, it can be proportional to the heat energy recycled in the condenser Alleviate the overload of the compressor and save the operating energy of the compressor. Background technique [0002] Generally speaking, a heat pump is a cooling and heating device that uses the heating or condensation heat of a refrigerant to conduct a low-temperature heat source to a high temperature or to conduct a high-temperature heat source t...
