Title: Air-cooled heat pump type air conditioner
Inventor: ENDO TAKESHI
IPC: F25B47/02
Filed: 1990-11-30
Abstract: PURPOSE:To prevent a reduction in performance caused by a returning of oil in a compressor and avoid a dangerous condition of breakage by a method wherein a liquid refrigerant tank for use in absorbing surplus liquid refrigerant having a solenoid valve at its inlet port and a flowing resistance pipe is disposed between an indoor heat exchanger and an expansion valve and its outlet port is connected to a gas-liquid separator through a solenoid valve. CONSTITUTION:A control panel 4 transmits a defrosting operation request signal to a frequency control circuit 3 when an outdoor heat exchanger 18 is frosted during its heating operation. The frequency control circuit 3 opens a solenoid valve 11 and then liquid refrigerant is gradually absorbed into a liquid refrigerant tank 13 through a capillary tube 12. Since the refrigerant returning to the gas-liquid separator 7 is apt to be dried, the liquid refrigerant in the gas-liquid separator 7 evaporates and it discharged into a cycle. An over-heating degree of discharged refrigerant of a compressor 5 under an operation of a pressure and temperature sensor 8 reaches its predetermined value, the control panel 4 closes the solenoid valve 11, increases the number of rotation of the compressor 5, opens a solenoid valve 16, sends hot gaseous refrigerant to the outdoor heat exchanger 18 and defrosts the frosted state. Since the surplus liquid refrigerant within the gas-liquid separator 7 is moved into the liquid refrigerant tank 13 before a rotation of the compressor 5 is increased, a liquid returning phenomenon accompanied by the increased rotation of the compressor 5 can be prevented.
