低減されるものとなる。Due to the above configuration, the refrigerator uses a VM cycle, and by adopting an external heating method that forcibly heats the working gas in the high temperature side heat exchanger, The high-temperature medium that has passed through the first switching valve is guided to the indoor heat exchanger during heating and to the outdoor heat exchanger during cooling, and the low-temperature medium that has passed through the low-temperature heat exchanger is connected to the first switching valve. The second switching valve allows the medium to be guided to the outdoor heat exchanger during heating and to the indoor heat exchanger during cooling. The medium is the third
The medium that has passed through the outdoor heat exchanger during heating and the medium that has passed through the indoor heat exchanger during cooling is guided to the medium temperature side heat exchanger by the switching valve, and the medium that has passed through the indoor heat exchanger during cooling is guided to the fourth switching valve attached to the third switching valve. It is guided to the low temperature side heat exchanger. In other words, the three-way valves are divided into two blocks and the actuator for operating the valves is shared to guide the low-temperature and high-temperature medium to the indoor heat exchanger and the outdoor heat exchanger. Since the medium and the high-temperature medium do not flow at the same time, heat loss inside the valve is reduced.
