Abstract:
1. An air conditioner including a high-pressure gas connection pipe, a low-pressure gas connection pipe, a liquid connection pipe, and a plurality of utilization side heat exchangers, one end of each of the utilization side heat exchangers being connected through a liquid pipe of a switching mechanism and an expansion mechanism to the liquid connection pipe, the other end of each of the utilization side heat exchangers being connected through the switching mechanism to the high-pressure gas connection pipe and the low-pressure gas connection pipe to be switchable between both the gas connection pipes, each of the utilization side heat exchangers being capable of performing a cooling operation and a heating operation individually, wherein each of the switching mechanisms comprises: the switching mechanism connected to a first of the utilization side heat exchangers, performing a heating operation, is configured so that the opening of the supercooling control valve is adjusted according to the air conditioning load of a second of the utilization side heat exchangers, performing a cooling operation, downstream of the liquid connection pipe connected to the first of the utilization side heat exchangers.
