PURPOSE: A heat pump is provided to easily enhance heating performance by further coupling a booster module to a freezing cycle unit. CONSTITUTION: A heat pump comprise a freezing cycle unit(1) and a booster module(2). The freezing cycle unit comprises a compressor(10), a first heat exchanger, an expansion unit(16), and a second heat exchanger(18). The first heat exchanger condenses refrigerant, which has been compressed by the compressor. The expansion unit expands refrigerant, which has been condensed by the first heat exchanger. The second heat exchanger evaporates refrigerant, which has been expanded by the expansion unit. The booster module is connected to the freezing cycle unit, separates and compresses vapor refrigerant from refrigerant, which flows from the first heat exchanger to the expansion unit, and then sends it to between the compressor and the first heat exchanger.
