AIR CONDITIONING DEVICE

摘要

An air-conditioning apparatus includes a refrigerant circuit configured to circulate a heat source-side refrigerant, the refrigerant circuit being a refrigerant-side flow path formed by connecting, with refrigerant pipes, a compressor, a refrigerant flow switching device, a heat source-side heat exchanger, a plurality of expansion devices, and a plurality of intermediate heat exchangers that exchange heat between the heat source-side refrigerant and a heat medium different from the refrigerant, a heat medium circuit configured to circulate the heat medium, the heat medium circuit being a heat medium-side flow path formed by connecting, with heat medium pipes, a pump, a plurality of heat medium flow switching devices, a plurality of use-side heat exchangers that act as indoor units, a plurality of heat medium flow control devices, and the intermediate heat exchangers, temperature detecting means for detecting a temperature of the heat medium sent from each of the intermediate heat exchangers to each of the use-side heat exchangers, and a temperature of the heat medium that has exited each of the use-side heat exchangers, opening degree control means for regulating a flow rate of the heat medium through each of the heat medium flow control devices, and computing means for computing a usage capacity of each of the indoor units from a rotation speed of the pump, an opening degree of each of the heat medium flow control devices, a temperature detected by the temperature detecting means, and a power consumption of each of the indoor units itself, and on a basis of the computed usage capacity and a power consumption for a common portion that is common to each of the indoor units, proportionally dividing the power consumption for the common portion among each of the indoor units.
