Title:
空気調和機
Document Type and Number:
Japanese Patent JP7398617
Kind Code:
B2
Abstract:
To provide an air conditioner capable of being operated to maintain comfortable temperature by continuing cooling operation.SOLUTION: An air conditioner includes a refrigeration cycle configured by connecting a compressor, a four-way valve, an indoor heat exchanger, an expansion valve and an outdoor heat exchanger so that a refrigerant flows in an order of the compressor, the four-way valve, the indoor heat exchanger, the outdoor heat exchanger and the four-way valve in a heating operation, room temperature detection means detecting a room temperature and target temperature setting means setting a target temperature, and controls air condition so that the room temperature becomes a target temperature. Between a suction pipe of the compressor and the four-way valve, a refrigerant flow passage switching device, a bypass circuit connected to a suction port of the compressor from the flow passage switching device, and a pressure reducing part are further provided. When such a condition that the room temperature becomes lower than the target temperature continues for a predetermined period of time, the flow passage switching device is operated to switch a flow passage.SELECTED DRAWING: Figure 3
