Abstract
In a heat pump apparatus of the invention, a refrigerant is circulated through a compressor, a radiator, a first throttle apparatus, a heat exchanger, a second throttle apparatusand an evaporatorin this order. The heat exchangercan be utilized as both a radiator and an evaporator by operating the first throttle apparatusand the second throttle apparatus. Therefore, even if the outside air temperature is high, discharge pressure and suction pressure of the compressor do not rise, the heat pump apparatus can be operated in a stable refrigeration cycle, and energy can be saved.
