Abstract

PURPOSE: To set a cooling or a heating mode at an individual indoor equipment by a method wherein it is selected whether high pressure refrigerant gas is fed to a heat source and a heat exchanger on the utilization side or low pressure refrigerant gas is taken out therefrom, and high pressure refrigerant liquid is heat-exchanged on the inlet side of a second expansion valve with low pressure refrigerant gas.
CONSTITUTION: With regard to an indoor air conditioned device in a cooling mode, high pressure refrigerant gas from a compressor 1 is converted into high pressure refrigerant liquid through an accumulator 3 and a solenoid valve 8 by means of a heater exchanger 2 on the heat source side. The high pressure refrigerant liquid is vaporized through 8 first expansion valve 5, an accumulator 3, a pipe 23, and a heat exchanger 12, and a second expansion valve 6 by means of a heat exchanger 4 on the utilization side. The low pressure refrigerant gas is returned to the compressor 1 through a solenoid valve 11, a heat exchenger 12, a pipe 22, and the accumulator 3. with regard to an indoor air conditioning device in a heating mode, high pressure refrigerant gas fed through a solenoid valve 9 and a pipe 21 is converted into high pressure refrigerant liquid through a solenoid valve 10 by means of the heat exchanger 4 on the utilization side and is fed to a pipe 23 through the second expansion valve 6 and the heat exchanger 12, and further fed through the pipe 23 to the indoor air conditioning device in a cooling mode.
