Claim:
1. An air-conditioning apparatus, comprising: a refrigerant circuit including, a controller configured to control operations of the compressor, the expansion valve, and an indoor fan provided in each of the indoor units; an opening and closing valve configured to open and close a refrigerant passage; and an expansion mechanism having porous bodies capable of passing a refrigerant therethrough, wherein the opening and closing valve and the expansion mechanism are connected in series, while the serially connected opening and closing valve and the expansion mechanism are connected in parallel with the expansion valve, in a heating mode in which the refrigerant of high-temperature from the compressor is supplied to the indoor heat exchanger, in a case where the controller stops an operation of at least one of the plurality of indoor units and causes at least one of the indoor units to operate, the controller closes the expansion valve and opens the opening and closing valve of the stopped indoor unit, respectively, and the controller opens the opening and closing valve when the opening degree of the expansion valve is greater than a fully-closed state and is smaller than a specific opening degree, and closes the opening and closing valve when the opening degree of the expansion valve is equal to or greater than the specific opening degree.
