AIR CONDITIONING APPARATUS

摘要

In this air conditioning apparatus, at least a single-circuit heat medium conveyor (202), a heat medium flow rate adjuster (201), and a heat medium flow rate control device (250) are provided as a heat medium system capable of adjusting the flow rate of a heat medium supplied to a heat source device-side heat exchanger (103) for performing heat exchange between a refrigerant and the heat medium. The air conditioning apparatus switches each of a plurality of usage-side heat exchangers (105) to cooling operation or heating operation in accordance with a control command, to perform simultaneous cooling and heating operations. The air conditioning apparatus is configured such that: in the heat source device-side heat exchanger (103), the refrigerant flows in accordance with the ratio of the total heating capacity to the total cooling capacity of the plurality of usage-side heat exchangers (105); and the heat medium flow rate control device (250) controls the flow rate of the heat medium supplied to the heat source device-side heat exchanger, on the basis of the total operating capacity of the heat source device-side heat exchanger and the difference between the total heating capacity and the total cooling capacity of the plurality of usage-side heat exchangers.
