Description
冷媒入口ポートＰＩ２から圧縮機１０、凝縮器２０、熱交換器３０の第１通路Ｈ１を経由して冷媒出口ポートＰＯ２に至る第１流路Ｆ１は、負荷装置３の第１膨張弁５０および蒸発器６０が配置される流路とともに、冷媒が循環する循環流路を形成する。以下、この循環流路を冷凍サイクルの「主冷媒回路」とも言う。 The first flow path F1 from the refrigerant inlet port PI2 to the refrigerant outlet port PO2 via the first passage H1 of the compressor 10, the condenser 20, and the heat exchanger 30 is the first expansion valve 50 of the load device 3 and evaporation. Together with the flow path in which the vessel 60 is arranged, a circulation flow path through which the refrigerant circulates is formed. Hereinafter, this circulation flow path is also referred to as a "main refrigerant circuit" of the refrigeration cycle.
室外ユニット２は、循環流路の第１通路Ｈ１の出口と冷媒出口ポートＰＯ２との間の部分から、第２通路Ｈ２の入口に冷媒を流す配管９１，９２，９４と、第２通路Ｈ２の出口から圧縮機１０の中間圧ポートＧ３に冷媒を流す配管９６とをさらに備える。以下において、主冷媒回路から分岐して第２通路Ｈ２を経由して圧縮機１０に冷媒を送る第２流路Ｆ２を、「インジェクション流路」とも言う。 The outdoor unit 2 has pipes 91, 92, 94 for flowing the refrigerant from the portion between the outlet of the first passage H1 and the refrigerant outlet port PO2 of the circulation flow path to the inlet of the second passage H2, and the second passage H2. Further, a pipe 96 for flowing a refrigerant from the outlet to the intermediate pressure port G3 of the compressor 10 is provided. In the following, the second flow path F2 that branches from the main refrigerant circuit and sends the refrigerant to the compressor 10 via the second passage H2 is also referred to as an “injection flow path”.
必ずしも行なわなくても良いが、好ましくは、制御装置１００は、さらにステップＳ４５において圧縮機１０の回転速度を増加させる。これにより、回収が進み凝縮しにくくなった残りの冷媒の回収の時間を短縮することができる。 It is not always necessary, but preferably, the control device 100 further increases the rotation speed of the compressor 10 in step S45 . As a result, it is possible to shorten the time for recovering the remaining refrigerant, which has been recovered and is difficult to condense.
