Claim Text:
1. An air-conditioning apparatus comprising: a refrigeration cycle device connecting a compressor that compresses a refrigerant, a refrigerant flow path switching device that switches a circulation path of the refrigerant, a heat source side heat exchanger that exchanges heat of the refrigerant, an expansion device that regulates a pressure of the refrigerant, and intermediate heat exchangers by piping to constitute a refrigeration cycle; a heat medium circulation circuit including, a control device that selects a use side heat exchanger absorbing heat into the heat medium and a use side heat exchanger emitting heat from the heat medium and controls to circulate the heat medium through both of the absorbing use side heat exchanger and the emitting use side heat exchanger, when determining that the heat medium cannot exchange heat in the intermediate heat exchanger, the control device controlling the switching by the flow path switching devices, wherein at least one of the use side heat exchangers is arranged in another circulation path that does not include the use side heat exchanger absorbing heat, and emits heat from the heat medium to air which is a heat exchange target, and the control device switches the flow path switching devices so that the flow of the heat medium related to the other circulation path circulates in the use side heat exchanger absorbing heat, when at least one temperature sensor senses that a temperature of the heat medium circulating in the circulation path including the use side heat exchanger absorbing heat is higher than a temperature of the heat medium related to the other circulation path when it is determined that the heat medium cannot exchange heat in the intermediate heat exchanger.
