AIR-CONDITIONING APPARATUS

摘要

An air-conditioning apparatus includes a compressor, an indoor heat exchanger configured to function as a condenser or an evaporator, indoor heat exchanges each configured to function as a condenser or an evaporator, a plurality of expansion valves each provided for a corresponding one of the indoor heat exchangers each configured to adjust a flow rate of a refrigerant that flows through the corresponding indoor heat exchanger and a controller configured to control an operation capacity of the compressor and opening degrees of a plurality of expansion devices. When increasing heat exchange performance of the indoor heat exchanger, the controller increases the operation capacity of the compressor and controls the opening degree of the expansion valve corresponding to the indoor heat exchanger to decrease the flow rate of the refrigerant that flows through the indoor heat exchanger.

1. An air-conditioning apparatus comprising: a compressor; a heat source side heat exchanger configured to function as a condenser or an evaporator; a plurality of use side heat exchangers each configured to function as a condenser or an evaporator; a plurality of expansion devices each provided for a corresponding one of the use side heat exchangers, and each configured to adjust a flow rate of a refrigerant that flows through the corresponding use side heat exchanger; and a controller configured to control an operation capacity of the compressor and opening degrees of the plurality of expansion devices, wherein
when increasing heat exchange performance of a first use side heat exchanger that is at least one, but not all, of the plurality of use side heat exchangers, the controller increases the operation capacity of the compressor, and controls the opening degree of the expansion device corresponding to a second use side heat exchanger that is at least one of the use side heat exchangers that perform a function identical to a function of the first use side heat exchanger, to decrease a flow rate of the refrigerant that flows through the second use side heat exchanger, the second use side heat exchanger being different from the first use side heat exchanger.
