Abstract
A heat pump system includes a compressor, a first heat exchanger, a second heat exchanger, and a valve device. The valve device includes a first connecting port connected to an exhaust port of the compressor, a second connecting port connected to a first port of the second heat exchanger, a third connecting port connected to an air suction port of the compressor, a fourth connecting port connected to a first port of the first heat exchanger, and a fifth connecting port connected to a fourth port of the first heat exchanger. In a refrigeration mode, the valve device fluidly couples the third connecting port to the air suction port, and the first heat exchanger operates as a falling film evaporator. In a heating mode, the valve device fluidly couples the first connecting port to the exhaust port, and the first heat exchanger operates as a condenser.
