초록 ▼

A refrigerant circulation system of the present invention includes a compressor, a condenser, a evaporator, a throttle device and a control unit. The control unit controls a composition of a refrigerant circulating in the refrigerant circulation system based on a temperature and pressure of the refrigerant of an inlet and outlet portion of the compressor, condenser, evaporator and throttle device. The control unit controls to open and close the throttle device to change the composition of the refrigerant circulating in the refrigerant circulation system.

대표청구항 ▼

[ What is claimed is:] [1.] A refrigerant circulating system using a refrigerant made of a nonazeotropic mixture including a plurality of types of refrigerants; comprisinga refrigerant circuit having a compressor for compressing the refrigerant, a first heat exchanger for condensing the refrigerant during a cooling operation and evaporating the refrigerant during a heating operation, a main throttle device for changing pressure of the refrigerant flowing therethrough and a second heat exchanger for evaporating the refrigerant during a cooling operation and condensing the refrigerant during a heating operation, which are connected in order;a low pressure receiver for storing a liquid refrigerant therein, said low pressure receiver being connected to said compressor;a four-way valve which is disposed between said compressor and said first heat exchanger, said four-way valve being directly connected to said low pressure receiver and being connected to said second heat exchanger;a high pressure receiver for storing a liquid refrigerant therein which are disposed between said first heat exchanger and said main throttle device;a bypass piping which connects a bottom portion of said high pressure receiver with said low pressure receiver;an auxiliary throttle device for changing pressure of the refrigerant therethrough;a third throttle devise disposed on said bypass piping;a super cooling heat exchanger which performs a heat exchange between said bypass piping and a main piping from said main throttle device to said auxiliary throttle device;wherein said refrigerant flows in the direction from said first heat exchanger to said second heat exchanger during the cooling operation, and said refrigerant flows in the direction from said second heat exchanger to said first heat exchanger during the heating operation.
