た。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an air-cooled heat pump type air conditioner that performs heating in combination with a hot water boiler. In general, an air-cooled heat pump type air conditioner 1, a hot water boiler 2, and a load as shown in FIG. The refrigeration cycle of the air-cooled heat pump type air conditioner 1 used as part of a system consisting of a side unit 3, a pump 4, a gas turbine 5, etc. is configured as shown in Figure tIX2, and the outside air temperature is high and the heat pump efficiency is high. Used in hot water boiler 2
is used when the outside air temperature is low and the heat pump efficiency is poor, and when the air-cooled heat pump type air conditioner 1 is in defrosting operation. 6 is a compressor, 7 is a water side heat exchanger, 8 is an air side heat exchanger, 9 is an accumulator, 11 is a blower, 12 is a strainer, 13 is a circulating water inlet, and 14 is an outlet. The dotted arrow indicates the flow direction of the refrigerant δ In the above configuration, if frost forms on the air side heat exchanger 8, the air conditioner 1 is stopped;
The structure is such that the hot water boiler 2 is operated to cover the load necessary for heating, and at the same time warms the refrigerant with hot water from the water side heat exchanger 7 to melt the frost on the air side heat exchanger 8. Since the heat is generated by the refrigerant through the pressure reducing device 10, which has a large resistance, there is a drawback that the defrosting time is long.

ポンプ式空気調和機の運転時間を良くすることのできる
空冷ヒートポンプ式空気調和様を提供することを目的と
するものである。The present invention has been made in view of the above points, and is an air-cooled heat pump type air conditioner that can shorten the defrosting operation time and improve the operation time of the air-cooled heat pump type air conditioner in terms of high heat pump efficiency. The purpose is to provide the following.
本発明は上記の目的を達成するために、除霜時冷凍サイ
クルの運転を停止し、温水ボイラを運転しているときに
温水によシ温められた冷媒を減圧装置を通さないで直接

ようにした特徴を有するものである。In order to achieve the above object, the present invention stops the operation of the refrigeration cycle during defrosting, and directs the heated refrigerant to the air side without passing it through a pressure reducing device when the hot water boiler is operating. It has the feature that the defrosting time is shortened by sending it into the heat exchanger.
以下、本発明を第３図に示す一実施例によね詳細に説明

The explanation is omitted. 15 is a solenoid valve, 16 is another refrigerant passage, which is connected in parallel with the pressure reducing device 10 and the main refrigerant passage 17 of the strainer 12, and which is connected to the water side heat exchanger 7 and the air side heat exchanger 8. There is.

れる。上記過程においては、電磁弁１５は閉じており、
他の冷媒通路」６には冷媒は流れない。Therefore, by operating the air-cooled heat pump air conditioner 1 during operation, the refrigerant compressed by the compressor 6 flows in the direction of the dotted arrow, and the high-temperature refrigerant flows into the water in the water-side heat exchanger 7. used as a heating heat source. The refrigerant liquid condensed and liquefied in the water side heat exchanger 7 flows through the main refrigerant passage 17, passes through the strainer 12, is decompressed and expanded by the pressure reducing device 10, and then exchanges heat with the outside air and absorbs heat in the air side heat exchanger 8. , and is sucked and compressed again into the compressor 6 via the Akiemulator 9. In the above process, the solenoid valve 15 is closed;
No refrigerant flows into the other refrigerant passages.

抗の大きい減圧装置１０の通路には冷媒は流れない。When frost forms on the air-side heat exchanger 8, the compressor 6 stops operating, and the air-cooled heat pump type air conditioner 1 stops operating. Then, the hot water boiler 2 is operated, and the water side heat exchanger 7
Heat is exchanged between the refrigerant and hot water inside the tank, and the refrigerant is heated. The solenoid valve 15 opens at the same time as the refrigeration cycle stops and the hot water boiler 2 starts, and the high-temperature, high-pressure refrigerant flows into the air-side heat exchanger 8 through another refrigerant passage 16, warming the surface of the heat exchanger and defrosting it. do. By opening the electromagnetic valve 15, the refrigerant does not flow into the passage of the pressure reducing device 10, which has a large resistance.
本発明は上記の如き構成にしたから、温められた冷媒は
