Description
Technical Field
The invention relates to the technical field of heat pumps, in particular to a heating device combining an air source and a water source.
Background
The heat pump water heater, also called air energy water heater, absorbs low temperature heat in the air, gasifies through fluorine medium, then pressurizes and heats up after compressing through a compressor, and then converts the water into heat through a heat exchanger, and the compressed high temperature heat energy heats up the water temperature. The heat pump water heater overcomes the defects that the solar water heater relies on sunlight to collect heat and is inconvenient to install. Because the air energy water heater works through medium heat exchange, the air energy water heater does not need an electric heating element to be in direct contact with water, avoids the danger of electric leakage of the electric water heater, also prevents the danger of possible explosion and poisoning of the gas water heater, and more effectively controls air pollution caused by exhaust gas discharged by the gas water heater.
However, the heat exchange efficiency of the existing heat pump water heater is low due to the limitation of the structure, and in order to improve the heat exchange efficiency, the applicant proposes a cascade heat pump comprising: the system comprises a first-stage compression circulation pipeline provided with a first heat exchanger, a second heat exchanger connected between the first-stage compression circulation pipeline and the second-stage compression circulation pipeline, and a water storage tank arranged in the second-stage compression circulation pipeline, wherein water is stored in the second heat exchanger, and the system is used for transmitting heat absorbed from the first-stage compression circulation pipeline to the second-stage compression circulation pipeline when the first-stage compression circulation pipeline and the second-stage compression circulation pipeline work simultaneously so as to heat the water in the water storage tank. The water in the water storage tank is heated by the refrigerant in the secondary compression circulation pipeline, and the temperature of the hot water output from the water storage tank is limited due to the unavoidable loss of heat in the transmission process, so that the use requirement of people on hot water with higher temperature cannot be met.

In addition, the technical features of the different embodiments of the present invention described below may be combined with each other as long as they do not collide with each other.
An embodiment of the air source and water source combined heating device shown in fig. 1 comprises a primary compression circulation pipeline 1 and a secondary compression circulation pipeline 2, wherein a first heat exchanger 3 and a second heat exchanger 4 are respectively arranged in the primary compression circulation pipeline 1 and the secondary compression circulation pipeline 2. The refrigerant in each stage of compression circulation pipeline is converted from low-temperature low-pressure refrigerant gas into high-temperature high-pressure refrigerant gas after compression treatment, so that heat is obtained, and the heat is used for exchanging heat with equipment in the circulation pipeline, and the refrigerant suitable for low-temperature environment and high-temperature environment is respectively selected in the primary compression circulation pipeline 1 and the secondary compression circulation pipeline 2. And the third heat exchanger 5 is connected between the primary compression circulation pipeline 1 and the secondary compression circulation pipeline 2. And the water inlet and outlet pipeline 6 is sequentially connected with the third heat exchanger 5 and the second heat exchanger 4 and is used for respectively absorbing heat in the primary compression circulation pipeline 1 and the secondary compression circulation pipeline 2 and discharging hot water for heating of a user.

The flowing direction of water in the water inlet and outlet pipeline 6 is opposite to the moving direction of the refrigerants in the primary compression circulation pipeline 1 and the secondary compression circulation pipeline 2. That is, the water of the water inlet pipeline 61 enters from the lower right end of the third heat exchanger 5, flows out from the upper left end of the third heat exchanger 5 to the middle pipeline 63, and at this time, the water absorbs the heat released by the refrigerant in the primary compression circulation pipeline 1, and the temperature is raised to a certain degree; then water in the middle pipeline 63 enters from the lower left end of the second heat exchanger 4, flows out from the upper right end of the second heat exchanger 4 into the water outlet pipeline 62, and absorbs heat released by the refrigerant in the secondary compression circulation pipeline 2 again, so that the temperature is further increased, and the water in the water inlet and outlet pipeline 6 always has the opposite flow direction with the refrigerant in the flowing process, thereby maintaining reverse heat exchange and improving the heat exchange efficiency.
The third heat exchanger 5 comprises two fluorine paths and a water path, wherein the two fluorine paths are arranged in the third heat exchanger, one fluorine path is communicated with the primary compression circulation pipeline 1, the other fluorine path is communicated with the secondary compression circulation pipeline 2, and two ends of the water path are respectively communicated with the water inlet pipeline 61 and the middle pipeline 63.

The primary compressor 7 and the secondary compressor 20 are used for converting the refrigerant in the circulating pipeline from low-temperature low-pressure gas into high-temperature high-pressure gas; the first liquid reservoir 8 and the second liquid reservoir 30 are used for storing the liquid condensed by the refrigerant after heat exchange with the third heat exchanger 5 or the second heat exchanger 4; the first throttle valve 9 and the second throttle valve 40 are used for cooling the gas in the refrigerant to form a low-temperature low-pressure gas-liquid mixture; the first heat exchanger 3 is used for exchanging heat between the low-temperature low-pressure gas-liquid mixture in the circulating pipeline and the external air so as to absorb heat in the external air, and the low-temperature low-pressure gas is obtained after evaporation; the first vapor-liquid separator 10 and the second vapor-liquid separator 50 are used for separating a small amount of liquid in the evaporated gas and then respectively delivering the separated liquid to the primary compressor 7 and the secondary compressor 20 for compression, thereby completing one cycle.

The refrigerant after heat release by the second heat exchanger 4 enters the second liquid storage device 30 to store condensed liquid, then is converted into a low-temperature low-pressure gas-liquid mixture through the second throttle valve 40, then enters the third heat exchanger 5 to absorb the residual heat in the first-stage compression circulation pipeline 1, enters the second gas-liquid separator 50 to separate gas and liquid, and finally returns to the second-stage compressor 20 to form circulation.
