とする空気調和機の除霜装置。 A refrigerant circuit is formed by sequentially connecting a compressor, a four-way valve, an indoor heat exchanger, a capillary, and an outdoor heat exchanger equipped with two upper and lower refrigerant pipe lines,
In the defrosting device for an air conditioner, which defrosts the high-temperature gas on the discharge side of the compressor by flowing into the outdoor heat exchanger using a four-way valve, there is usually an "open" opening in front of the inlet side pipe of the upper refrigerant pipe. The first solenoid valve in the "closed" state is connected to the chamber from between the first solenoid valve and the inlet pipe of the upper refrigerant pipe through the second solenoid valve, which is normally in the "closed" state, and the second capillary. By forming a bypass circuit connected to the inlet side piping of the inner heat exchanger, and closing the first solenoid valve and opening the second solenoid valve during defrosting operation, the inlet side piping of the lower refrigerant pipe is connected to the inlet side piping of the lower refrigerant pipe. A defrosting device for an air conditioner, characterized in that high-temperature gas is caused to flow through the inlet pipe of the upper refrigerant conduit through the bypass circuit to quickly defrost the outdoor heat exchanger.
