Title:
HEAT PUMP
Document Type and Number:
WIPO Patent Application WO/2023/120960
Kind Code:
A1
Abstract:
A heat pump is disclosed. The heat pump may comprise: a compressor for compressing a refrigerant provided from an accumulator; a water-refrigerant heat exchanger for allowing heat to be exchanged between water and the refrigerant discharged from the compressor; a main expansion valve for expanding the refrigerant having passed through the water-refrigerant heat exchanger; an outdoor heat exchanger which allows heat to be exchanged between outdoor air and the refrigerant having passed through the main expansion valve, and which is connected to the accumulator; a main pipe which connects the water-refrigerant heat exchanger and the outdoor heat exchanger, and at which the main expansion valve is provided; an internal heat exchanger provided at the main pipe between the water-refrigerant heat exchanger and the main expansion valve; an injection pipe which has one end connected to a first point of the main pipe between the internal heat exchanger and the main expansion valve and the other end connected to the compressor, and in which the internal heat exchanger is provided; an injection valve provided at the injection pipe between the first point and the internal heat exchanger; a bypass pipe, which has one end connected to a second point of the main pipe between the water-refrigerant heat exchanger and the internal heat exchanger and the other end connected to a third point of the main pipe between the internal heat exchanger and the first point; and a bypass valve provided at the bypass valve.
