Description

Technical Field

[0001] The utility model relates to the technical field of liquid-cooled variable-frequency air-source heat pumps, in particular to a liquid-cooled variable-frequency air-source heat pump system. Background Art

[0002] With the rapid development of society and economy, air source heat pump is an energy-saving device that uses high-level energy to transfer heat from low-level heat source air to high-level heat source. It is a form of heat pump. As the name suggests, heat pump is like a pump, which can convert low-level heat energy that cannot be directly used into high-level heat energy that can be used, thereby achieving the purpose of saving some high-level energy.

[0003] A liquid-cooled variable-frequency air-source heat pump system, patented as CN202222902585.9, is disclosed. This system includes a compressor, a condenser, a throttling element, and an evaporator, interconnected by pipes to form a refrigerant circulation system. During summer cooling, the system operates according to the cooling mode. High-pressure steam discharged from the compressor passes through a four-way valve into the condenser. The refrigerant vapor is condensed into liquid, then passes through the throttling element into the evaporator, where it absorbs heat and cools the indoor air. The evaporated refrigerant vapor then passes through the four-way valve and is drawn into the compressor, repeating the cycle. During winter heating, the four-way valve is first turned to the heat pump operating position. High-pressure refrigerant vapor discharged from the compressor flows through the four-way valve into the indoor evaporator. The latent heat released by the cold refrigerant vapor heats the indoor air, achieving indoor heating. The condensed liquid refrigerant then flows back through the throttling element into the condenser, absorbing external heat and evaporating. The evaporated vapor then passes through the four-way valve and is drawn into the compressor, completing the heating cycle.

[0004] However, when the heat pump in this technology is used in winter, the outside temperature is low, which may cause the heat of the heat pump to dissipate easily, resulting in a lower temperature of the water that finally flows out; when the heat pump in this technology is used in summer, its heat dissipation performance is poor, which may cause the heat pump to generate too much heat. Excessive heat will lead to a shorter service life of the heat pump and motor. Therefore, it does not meet existing needs. In this regard, we propose a liquid-cooled variable frequency air source heat pump system. Utility Model Content

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

The movable fastener 14 slides in the long waist hole 4, and the four insulation boards 2 are respectively movable vertically on the four end faces of the system outer frame 1, which enables the insulation board 2 to block the front ends of the air-permeable board 5 and the fixed board 6.

[0022] A fixing plate 6 is fixedly connected to the front end of the lower side of the system outer frame 1, wherein a fan bracket 7 is provided in the middle of the front end of the fixing plate 6, and air-permeable plates 5 are provided at both ends and the rear side of the lower side of the system outer frame 1. The setting of the air-permeable plates 5 improves the heat dissipation effect inside the bottom end of the system outer frame 1.

[0023] The upper side of the inner part of the above-mentioned system outer frame 1 is provided with a liquid-cooled variable frequency air source system body, and the lower side of the liquid-cooled variable frequency air source system body is connected to a heat pump 8. A dual-axis motor 9 is provided on one side of the heat pump 8. A fan 10 is connected to the output shaft at one end of the dual-axis motor 9 through a coupling, and the fan 10 rotates in the fan bracket 7.

[0024] Among them, after the overall dual-axis motor 9 is running, the output shaft at one end of the dual-axis motor 9 drives the heat pump 8 to operate, and at the same time, the output shaft at the other end of the dual-axis motor 9 drives the fan 10 inside the fan bracket 7 to rotate. The rotation of the fan 10 blows air to the bottom end of the system outer frame 1. This setting can perform air cooling on various electrical equipment at the bottom end of the system outer frame 1, which enables the dual-axis motor 9 to drive the heat pump 8 to operate while driving the fan 10 on one side to rotate.

[0026] When in use, the spring 17 connected to one end of the internal cavity of the fixed frame 11 has an elastic force of extension. This elastic force causes the spring 17 to push the movable column 16, which causes the movable column 16 to drive the pin 12 at one end to move horizontally, and finally causes one end of the pin 12 to be inserted into the socket 13 on the movable block 14. The insertion and cooperation between the pin 12 and the socket 13 mounts the entire movable block 14. The mounting of the movable block 14 causes the entire insulation board 2 to be located on the upper side of the breathable board 5 and the fixed board 6.

This arrangement allows the operation of the fan 10 to dissipate heat inside the bottom end of the system outer frame 1. In summary, the mode in which the thermal insulation plate 2 is located on the upper side of the breathable plate 5 and the fixed plate 6 is suitable for the overall liquid-cooled variable-frequency air source heat pump system to perform air-cooling treatment in summer, thereby reducing the temperature of the overall system when used in summer.
