Original Abstract Submitted
a heat pump may include a compressor configured to compress a refrigerant; an accumulator configured to supply the refrigerant to the compressor; a receiver connected to the accumulator; a fluid-refrigerant heat exchanger configured to exchange heat between a fluid, such as water, and the refrigerant; an outdoor heat exchanger configured to exchange heat between outdoor air and the refrigerant; a 4-way valve configured to guide the refrigerant, discharged from the compressor, to flow into the fluid-refrigerant heat exchanger or the outdoor heat exchanger; at least one expansion valve disposed between the fluid-refrigerant heat exchanger and the outdoor heat exchanger; a first valve disposed between the fluid-refrigerant heat exchanger and the receiver; a second valve disposed between the compressor and the receiver; and a third valve disposed between the receiver and the accumulator.
