The air source heat pump air-supplying and enthalpy-increasing cooling and heating machine shown in fig. 1 comprises a compressor 1, a four-way valve 2, a first electromagnetic valve 3, a hydrothermal heat exchanger 7, a throttle valve 8 and a second heat exchanger 9 which are sequentially connected, and further comprises a heat storage pipe 10 connected with the four-way valve 2, a second electromagnetic valve 11 connected to the heat storage pipe 10, an expansion valve 12 and an air-supplying and enthalpy-increasing heat exchanger 13. The first electromagnetic valve 3 is connected with an interface A of the four-way valve 2, the second heat exchanger 9 is connected with an interface B of the four-way valve 2, the heat storage pipe 10 is connected with the hydrothermal heat exchanger 7 in parallel, one end of the expansion valve 12 is connected to the second electromagnetic valve 11, the other end of the expansion valve 12 is connected to the air-supplying enthalpy-increasing heat exchanger 13, and the air-supplying enthalpy-increasing heat exchanger 13 is connected between the expansion valve 12 and the compressor 1.
The hydrothermal heat exchanger 7 comprises a first heat exchanger 4, a water tank 6 and a heat storage layer 5, wherein a phase-change material is filled in the heat storage layer 5, the first heat exchanger 4 is connected to the first electromagnetic valve 3, and a phase-change material is also filled in the heat storage pipe 10. The phase-change material is one or more of metal alloy phase-change material, paraffin, PCM or n-dodecane, and paraffin is preferred in the embodiment.
The heating working principle is as follows: the refrigerant is compressed by the compressor 1 to become high-level high-pressure gas, enters the first heat exchanger 4 through the four-way valve 2, is changed into medium-temperature high-pressure liquid after heat release of the first heat exchanger 4, is changed into low-temperature low-pressure liquid after passing through the throttle valve 8, is changed into low-temperature low-pressure gas after absorbing heat through the second heat exchanger 9, and then enters the compressor 1 through the four-way valve 2 to continue circulation. In winter, along with the reduction of the ambient temperature, the evaporation capacity of the cooling liquid in the second heat exchanger 9 is reduced, the compression ratio of the compressor 1 is increased, the exhaust temperature of the compressor 1 is easily increased, when the temperature is increased to be the set temperature, the liquid passing through the hydrothermal heat exchanger 7 enters the expansion valve 12, the liquid supply capacity is increased, the cooling liquid enters the compressor 1 through the air-supplementing enthalpy-increasing heat exchanger 13, the enthalpy and moisture content of the compressor 1 are improved, the exhaust temperature is reduced, and the normal work of the compressor 1 is ensured.
The heat storage layer 5 in the hydrothermal heat exchanger 7 is filled with paraffin materials, absorbs the heat of the first heat exchanger 4, heats the water in the water tank 6, and keeps the hot water supply, and even after the heat pump system is stopped, the heat stored in the heat storage layer 5 can also ensure the uninterrupted supply of the hot water in the water tank 6.

A security filter can be connected to the water inlet 62 of the water tank 6 to remove impurities in water, reduce scale generation and influence heat transfer effect. When the second heat exchanger 9 frosts, the heat storage pipe 10 and the second electromagnetic valve 11 can be opened to defrost, the temperature required by defrosting is provided by the heat storage pipe 10, an electric heating defrosting system does not need to be arranged independently, and energy consumption is saved.
During refrigeration, the working principle of the cooling and heating machine of the embodiment is as follows: the refrigerant is changed into high-temperature high-pressure gas after passing through the compressor 1, enters the second heat exchanger 9, is changed into medium-temperature high-pressure liquid after releasing heat, is changed into low-temperature low-pressure liquid after passing through the throttle valve 8, is subjected to heat absorption and cooling by the first heat exchanger 4, returns into the compressor 1 through the four-way valve 2, and continues to circularly work. The temperature is higher in summer, along with the temperature rising, the coolant liquid in the second heat exchanger 9 can not get the complete condensation, causes compressor 1 exhaust temperature to rise easily, and when exhaust temperature rose to the settlement temperature, the liquid that the second heat exchanger 9 came out increased the liquid supply volume through expansion valve 12, and the heat exchanger 13 gets into compressor 1 through tonifying qi enthalpy again, improves compressor 1 suction enthalpy moisture content, reduces exhaust temperature, guarantees that compressor 1 normally works.
The heat storage layer 5 in the hydrothermal heat exchanger 7 is filled with paraffin materials, so that when the first heat exchanger 4 absorbs heat, the temperature of water in the water tank 6 is reduced, and the indoor refrigeration effect can be realized through the floor heating system.
