Claim:
1. An air-conditioning apparatus, comprising: a refrigeration cycle that connects, a heat medium circulation circuit that connects, heating of said heat medium by said intermediate heat exchanger to heat said heat medium and cooling of said heat medium by said intermediate heat exchanger to cool said heat medium are simultaneously performed, said heat medium flow path switching apparatuses enable to perform simultaneous cooling and heating operations by making said heated heat medium pass through said use side heat exchanger that performs heating and making said cooled heat medium pass through said use side heat exchanger that performs cooling, said heat source side heat exchanger, said intermediate heat exchanger, and said plurality of use side heat exchangers are formed in separate housings respectively, the air-conditioning apparatus further includes: wherein the relay unit side controller is configured to transmit a control signal containing data on adjustment values of a control target value of a condensing temperature of the refrigerant passing through the intermediate heat exchanger that heats said heat medium and/or an evaporating temperature of the refrigerant passing through the intermediate heat exchanger that cools said heat medium to said outdoor unit side controller, and said outdoor unit side controller updates a control target value of said condensing temperature and/or evaporating temperature held by said outdoor unit side controller by increasing or decreasing said control target value of said condensing temperature of the refrigerant passing through the intermediate heat exchanger that heats said heat medium and/or an evaporating temperature of the refrigerant passing through the intermediate heat exchanger that cools said heat medium in accordance with the data on adjustment values transmitted by said relay unit side controller to said outdoor unit side controller.
