Low-voltage high-temperature special type air source heat pump

The invention relates to a low-pressure high temperature special wind source heat pump. A refrigerating circulation loop is connected in series with a compressor, a first-stage condenser, a second-stage condenser, a third-stage condenser and a wind source evaporator in sequence. A water evaporator is connected between an outlet end of the refrigerating circulation loop of the third-stage condenser and an outlet end of the refrigerating circulation loop of the wind source evaporator. A water inlet of a water jacket of the water evaporator is communicated with a water outlet of a water jacket of the third-stage condenser and a chilled water loop is formed between the water jacket of the water evaporator and the water jacket of the third-stage condenser. By a hot water pipeline and a heating circulation pump, the connection between the water jacket of the second condenser and the water jacket of the first condense forms an indoor water system. A storage pump is connected with the first-stage condenser and an accumulator to form energy storage and supplying for loop. The device has the function of providing water with outlet temperature higher than 70 DEG C which cannot be realized by the normal temperature wind source heat pump and the normal temperature water source heat pump, and needs no water source but has the COP value superior to that of the ground source heat pump and can replace oil fired boilers and gas fired boilers.
