Description

Technical Field

[0001] This utility model relates to the field of air source heat pump technology, and in particular to an integrated ultra-low noise air source heat pump unit with evaporation and condensation. Background Technology

[0002] In the context of dual carbon emissions, air source heat pumps have become one of the main pathways for energy conservation and carbon reduction. Ordinary air source heat pumps are generally only suitable for environments with temperatures above -5°C. They suffer from severe heat loss and low heating efficiency below -5°C, and cannot operate normally below -10°C. While ordinary air source heat pumps can provide cooling in summer, their energy efficiency ratio (EER) is low, typically around 3.2. Cooling and heating air source heat pumps are effective in southern regions but less suitable for cold and frigid northern regions. In recent years, vapor injection enthalpy-enhancing air source heat pumps have solved the heating problem in low-temperature environments, but they still suffer from low cooling efficiency. Against the backdrop of vigorously promoting the use of renewable energy, ordinary air source heat pumps, compared to ground source heat pumps and traditional chillers, exhibit lower cooling efficiency and poorer operational economy.

[0003] This invention overcomes the shortcomings of traditional air source heat pumps, such as unstable operation in low-temperature winter environments, low heating efficiency, and low cooling efficiency in high-temperature summer environments. It can achieve a COP>3.0 for heating at 0℃, high-efficiency heating at -20℃, and EER>5 for cooling in summer. At the same time, the unit adopts an integrated structure, which has the advantages of simple system, convenient construction, small footprint, and low investment.

[0004] Traditional air source heat pumps are very noisy during operation, often exceeding 75dB, which significantly impacts the living and working environments of surrounding users, limiting their application in urban centers. Utility Model Content

[0016] The heating cycle, subcooling cycle and refrigeration cycle three sets of circulation pipelines and equipment are combined into one structure. The heating cycle pipeline and the refrigeration cycle pipeline are connected in parallel. The outdoor air evaporator 6 is placed above the base 21, and the outdoor evaporative condenser 9 is placed on the side of the base 21.

The integrated ultra-low noise air source heat pump unit with evaporation and condensation operates the heating pipeline system when the temperature is high in winter, and operates the heating pipeline and subcooling pipeline system when the temperature is low to ensure efficient heating in winter. In summer, it operates the cooling pipeline system, and the heating pipeline system and the cooling pipeline system serve as backups for each other during summer cooling. Working Principle: This utility model operates in three modes: low-temperature heating in winter, ultra-low-temperature heating in winter, and cooling in summer. In the low-temperature heating mode, the third shut-off valve 17, the fourth shut-off valve 18, the fifth shut-off valve 19, and the sixth shut-off valve 20 are closed, while the first shut-off valve 15 and the second shut-off valve 16 are opened, operating only the heating circulation pipeline. When the system starts, the low-pressure refrigerant vapor is first compressed by the vapor injection enthalpy-increasing compressor 1 into high-temperature, high-pressure vapor. Then, it passes through the four-way reversing valve 2 and undergoes condensation and heat release in the indoor heat exchanger 3, becoming a high-pressure, low-temperature liquid. It then enters the intermediate heat exchanger 4 and undergoes throttling and expansion through the heating expansion valve 5, becoming a low-pressure, low-temperature liquid. Finally, it enters the outdoor evaporator 6 to absorb residual heat from the outdoor air, becoming a low-temperature, low-pressure gas. This gas then re-enters the vapor injection enthalpy-increasing compressor 1 for compression, becoming high-temperature, high-pressure refrigerant vapor, and so on. The refrigerant absorbs residual heat from the low-temperature outdoor air through state changes and releases it to the energy-consuming buildings through the indoor heat exchanger. During ultra-low temperature heating in winter, close the fifth shut-off valve 19 and the sixth shut-off valve 20, and open the first shut-off valve 15, the second shut-off valve 16, the third shut-off valve 17, and the fourth shut-off valve 18 to operate the heating circulation pipeline and the subcooling circulation pipeline. When the system starts, the low-pressure refrigerant vapor is first compressed by the jet enthalpy-increasing compressor 1 and becomes high-temperature and high-pressure vapor. Then, after passing through the four-way reversing valve 2, it is condensed and released heat by the indoor heat exchanger 3, and the refrigerant becomes a high-pressure low-temperature liquid. It is then divided into two paths. One path passes through the cold expansion valve 7 and becomes a low-temperature and low-pressure liquid, which then enters the intermediate heat exchanger to absorb the heat of the other high-pressure low-temperature liquid, further cooling the other high-pressure low-temperature liquid and achieving subcooling. After absorbing heat, the steam in one path becomes low-temperature, low-pressure steam and then enters the vapor injection compressor 1. The other path, high-pressure, low-temperature liquid, enters the intermediate heat exchanger, where its temperature further decreases before entering the heating expansion valve 5 for throttling and expansion. It also becomes a low-pressure, low-temperature liquid before entering the outdoor evaporator 6 to absorb residual heat from the outdoor air, becoming a low-temperature, low-pressure gas. This gas then passes through the four-way reversing valve 2 and enters the vapor injection compressor 1, where it mixes with the other low-temperature, low-pressure steam and is compressed together by the vapor injection compressor 1, becoming high-temperature, high-pressure refrigerant vapor. This cycle continues. The refrigerant absorbs residual heat from the low-temperature outdoor air through a state change and then releases it to the energy-consuming buildings through the indoor heat exchanger. Because the refrigerant is subcooled, it can achieve heat absorption and heating in ultra-low temperature environments. During summer heating operation, the first shut-off valve 15, the second shut-off valve 16, the third shut-off valve 17, and the fourth shut-off valve 18 are closed, while the fifth shut-off valve 19 and the sixth shut-off valve 20 are opened to operate the refrigeration cycle pipeline. When the system starts, the low-pressure refrigerant vapor is first compressed by the vapor injection enthalpy-increasing compressor 1 into high-temperature, high-pressure vapor. Then, it passes through the four-way reversing valve 2 and undergoes evaporation and condensation in the outdoor evaporative condenser 9, releasing heat and becoming a high-pressure, low-temperature liquid. It then enters the refrigeration expansion valve 8 for throttling and expansion, becoming a low-pressure, low-temperature liquid before entering the indoor heat exchanger 3 to absorb residual heat from the building, becoming a low-temperature, low-pressure gas. This gas then passes through the four-way reversing valve 2 and enters the vapor injection enthalpy-increasing compressor 1 for compression, becoming high-temperature, high-pressure refrigerant vapor. This cycle repeats. By changing its state, the refrigerant absorbs residual heat from the building and releases it to the outdoor air through the outdoor evaporative condenser 9, thus achieving heat absorption and cooling in a high-temperature environment. In the outdoor evaporative condenser 9, the building's waste heat is released to the circulating water through the heat exchange coil 11. The circulating water is pressurized and circulated by the circulating water pump 10 to absorb heat from the heat exchange coil 11 through evaporation, and the water vapor is released into the surrounding air through the top fan 14.

[0017] The upper ends of the external air evaporator 6 and the outdoor evaporative condenser 9 are provided with closed sound-absorbing louvered boxes 22 that are matched with them. This arrangement can effectively eliminate the noise of the fan operation and ensure the ultra-low noise operation of the unit.

[0018] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
