Abstract
A heat pump cycle includes a compressor having a suction port and a discharge port, a heating heat exchanger which heats air, a gas-liquid separator, and a cooling heat exchanger which cools air upstream of the heating heat exchanger in an air flow direction. The heat pump cycle further includes an intermediate pressure passage which guides gas refrigerant from the gas-liquid separator to the suction port. A variable open-close portion opens the intermediate pressure passage and decompresses the gas refrigerant in the intermediate pressure passage, so that the gas refrigerant is introduced into the suction port when a bypass dehumidifying-heating mode is selected as a dehumidifying-heating mode in which the air having been heated in the heating heat exchanger becomes equal to or higher than air in an air-conditioning target space in temperature.
