REFRIGERATION CYCLE SYSTEM WITH MULTI HEAT EXCHANGER

摘要

The present invention provides a multi heat exchange refrigeration cycle system formed to remarkably reduce defrosting time and optimally maintaining the state of a refrigerant flowing into an evaporator. The multi heat exchange refrigeration cycle system includes: a compressor discharging a refrigerant of a gas state by compressing the refrigerant at a high temperature and a high pressure; a four-way valve connected to the compressor by a refrigerant flow path; a first heat exchanger connected to the four-way valve by the refrigerant flow path and exchanging the heat between the refrigerator and a heat source of the outside; a second heat exchanger connected to the first heat exchanger and the four-way valve by the refrigerant flow path and exchanging the heat between the refrigerant and the heat source of the outside; and a multi heat exchange unit installed on the refrigerant flow path connecting the first heat exchanger and the second heat exchanger and exchanging the heat between the refrigerants multiple times. The multi heat exchange unit exchanges the heat between the refrigerant flowing the refrigerant flow path connecting from the first heat exchanger to the second heat exchanger and the refrigerant discharged from the second heat exchanger and exchanges the heat between the refrigerant flowing in the refrigerant flow path connecting from the first heat exchanger to the second heat exchanger and the refrigerant flowing an eco flow path which is formed as the refrigerant connecting the first heat exchanger and the multi heat exchange unit flow path is diverged.
