is a dehumidification capillary, and 7 and 8 are valves. A indicates the wind direction of outdoor air, and B indicates the wind direction of indoor air. During cooling operation, valve 7 is closed and valve 8 is opened, and the refrigerant flows as shown by the solid line to cool the inside of the room. During dehumidification operation, valve 7 is opened, valve 8 is closed, and the refrigerant flows as shown by the dotted line to dehumidify the interior of the room.

ものであることもわかつた。 In the above-described refrigeration cycle, a large amount of noise was generated during dehumidifying operation, and the condition was very poor for use as an air conditioner. As a result of investigating the cause of this noise, it was found that it was caused by gas refrigerant being mixed into the liquid refrigerant flowing into the dehumidifying capillary 6. It was also found that this gas refrigerant flowed directly from the cooling capillary 5 due to the pressure loss between the valve 7 and the reheater 3.

調和機に関するものである。 The present invention relates to an air conditioner that prevents the gas refrigerant flowing out of the cooling capillary 5 from directly flowing into the dehumidification capillary 6 during dehumidification operation, thereby eliminating the source of noise generation.

る。 An example of the present invention will be explained below using an embodiment shown in FIG. During dehumidifying operation, the compressor, condenser, reheater, dehumidifying capillary 6, evaporator, and compressor are connected in this order through pipes, one end of which is connected to the middle of the pipe inside the reheater 3, and the other end of the pipe connected to the inside of the reheater 3. A cooling capillary 5 is provided that is connected to a pipe that communicates the condenser and the evaporator. By doing this, the gas refrigerant flowing out of the cooling capillary 5 is liquefied in the reheater 3, and flows into the dehumidifying capillary 6 connected to the pipe at the end of the reheater 3 as a liquid refrigerant. The middle of the pipe inside the reheater to which the cooling capillary 5 is connected is close to the pipe position at the end of the reheater to which the dehumidification capillary 6 is connected, and the gas flowing into the reheater 3 from the cooling capillary 5 It is necessary that the refrigerant is liquefied in the reheater 3. This is because if the cooling capillary 5 and dehumidifying capillary 6 connected to the reheater 3 are separated by a large distance, a problem arises in that the heat exchanger between them does not function sufficiently during cooling operation, resulting in a decrease in cooling capacity.

る。 As described above, in the present invention, the gas refrigerant flowing out from the cooling capillary 5 during the dehumidifying operation is transferred to the dehumidifying capillary 6.
It is possible to prevent the gas refrigerant from directly flowing into the dehumidifying capillary 6, thereby reducing the noise generated in the dehumidifying capillary 6.
