Patent attributes
An air conditioner is configured to be switchable between a heating mode and a cooling mode. In the cooling mode, a high-temperature heat medium circulates between a high-pressure side refrigerant-heat medium heat exchanger and a high-temperature heat medium-outside air heat exchanger in a state where a refrigerant circulates in an air-cooling heat exchanger. In the heating mode, the high-temperature heat medium circulates between the high-pressure side refrigerant-heat medium heat exchanger and an air-heating heat exchanger, while a low-temperature heat medium circulates between a low-pressure side refrigerant-heat medium heat exchanger and a low-temperature heat medium-outside air heat exchanger, in a state where the refrigerant circulates in the low-pressure side refrigerant-heat medium heat exchanger.
