HYBRID HEAT PUMP TYPE HEAT AND COOLING SYSTEM

摘要

A hybrid heat pump system is provided to improve hot water supply efficiency by using four connection pipes in which the refrigerant gas circulates and two four-way valves. A hybrid heat pump system comprises four refrigerant pipes(100) connecting an outdoor unit(2) and an indoor unit(3), two four-way valves(110,120) converting a refrigerant circuit, and a water boiling heat exchanger(200) in which the refrigerant gas discharged from a compressor circulates. The refrigerant pipes include a first refrigerant pipe(101) inducing the refrigerant gas discharged from the compressor to the water boiling heat exchanger, a second refrigerant pipe(102) circulating the refrigerant gas induced to the water boiling heat exchanger toward the outdoor unit, a third refrigerant pipe(103) circulating the refrigerant gas circulating to the outdoor unit toward the indoor heat exchanger, and a fourth refrigerant pipe(104) circulating the refrigerant gas circulating to the indoor heat exchanger toward the outdoor heat exchanger.
