Abstract
A heat pump equipped with an extraction heat exchanger includes a compressor sucking low-temperature-and-low-pressure liquid refrigerant, and compressing and discharging the low-temperature-and-low-pressure liquid refrigerant into high-temperature-and-high-pressure liquid refrigerant, a condenser in which air passing therethrough absorbs heat from the liquid refrigerant to liquefy the liquid refrigerant, an evaporator in which refrigerant absorbs heat from indoor air and is evaporated to cool indoor air, a main electronic expansion valve connected between the condenser and the evaporator to decompress the liquid refrigerant liquefied in the condenser such that the decompressed refrigerant is easily evaporated in the evaporator and flows at a predetermined flow rate; and the extraction heat exchanger branching a part of the high-temperature-and-high-pressure liquid refrigerant, and performing and bypassing heat exchange between high-temperature-and-high-pressure super-cooled liquid refrigerant and high-temperature-and-high-pressure refrigerant passing through a heat exchanging refrigerant tube between the condenser and the main electronic expansion valve to an accumulator.
