TWIN ROTARY COMPRESSOR AND HEAT PUMP HAVING THE SAME

摘要

A heat pump of the present invention includes: a twin rotary compressor including an intermediate plate disposed between a first compression chamber and a second compression chamber, sucking and compressing a refrigerant in the first compression chamber and the second compression chamber, and the discharging the refrigerant; an outdoor heat exchanger condensing or evaporating a refrigerant; an indoor heat exchanger evaporating or condensing a refrigerant; an expansion device expanding a refrigerant between the outdoor heat exchanger and the indoor heat exchanger; and an injection channel through which a refrigerant is injected into the twin rotor compressor, between the outdoor heat exchanger and the indoor heat exchanger, in which the twin rotary compressor includes: an intermediate plate connection channel guiding a refrigerant guided to the injection channel to the intermediate plate; and an intermediate plate injection channel through which a refrigerant guided to the intermediate plate connection channel is injected into the first compression chamber and the second compression chamber after passing through the intermediate plate, such that a refrigerant can be injected into both of the first and second compression chambers by a simple structure using the intermediate plate without injection pipes for injecting the refrigerant into the first and second compression chambers.
