Abstract
Use side heat exchangers, an intermediate heat exchanger that heats a heat medium flowing to the use side heat exchangers, an intermediate heat exchanger that cools the heat medium flowing to the use side heat exchangers, three-way valves that switch between a flow path connecting the intermediate heat exchanger to the use side heat exchangers and a flow path connecting the intermediate heat exchanger to the use side heat exchangers, and three-way valves and bypasses that control the flow rate of the heat medium flowing into the use side heat exchangers are included. When at least one of the use side heat exchangers is switched from a stop state to an operation state or switched to another operation mode, the flow rate of the heat medium flowing into this use side heat exchanger is suppressed, and a change in air output temperature in the use side heat exchangers other than this use side heat exchanger is suppressed.
