ABSTRACT:
A refrigeration equipment includes a vapor compression type of refrigerant circuit that prevents a decline in refrigeration ability in user side heat exchangers when the refrigerant condensed by a heat source side heat exchanger is reduced in pressure and sent to the user side heat exchangers. An air conditioner includes a refrigerant liquid junction line and a refrigeration gas junction line, a heat source side expansion valve, a cooler, and a first pressure detection mechanism. The heat source side expansion valve reduces the pressure of the refrigerant that is condensed in the heat source side heat exchanger and sent to the user side heat exchangers. The cooler cools the refrigerant that is condensed in the heat source side heat exchanger and sent to the user side heat exchangers. The first pressure detection mechanism detects the pressure of the refrigerant after the pressure thereof has been reduced by the heat source side expansion valve.
