Description

Technical Field

[0001] This utility model relates to the field of air conditioning heat pump technology, and in particular to an antifreeze air conditioning heat pump unit. Background Technology

[0002] When the outdoor temperature is too low, existing air conditioning heat pump units experience several problems. First, the media inside the unit (such as refrigerant and antifreeze) are prone to freezing in low temperatures, leading to blockages in the circulation system. This not only affects the normal operation of the unit but may also cause irreversible damage to the equipment. Second, frost easily forms on the evaporator surface. The presence of frost severely hinders the heat exchange process, significantly reduces the evaporator's efficiency, increases the unit's energy consumption, and may even force the unit to frequently shut down for defrosting, greatly affecting the continuity and stability of heating. Furthermore, frequent operation in harsh low-temperature environments accelerates the aging of internal components and shortens the overall service life of the unit. Utility Model Content

[0003] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide an anti-freeze air conditioning heat pump unit. When the outdoor temperature is too low, the outer shell of the unit can be sealed by a closing mechanism to isolate it from the external environment. At the same time, some of the hot air in the heating pipe is guided back to the outer shell for heating. This prevents the medium inside the unit from freezing due to low temperature and prevents the evaporator from reducing its working efficiency due to frost. This extends the working life of the unit and improves its stability during operation.

The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0024] Reference Figure 1-6 This utility model discloses an anti-freezing air conditioning heat pump unit, comprising: an indoor shell 18, a condenser 4, a compressor 6, and a throttling valve 3 fixedly connected to the inner wall of the indoor shell 18; an inlet pipe 20 fixedly connected to the inner wall of the throttling valve 3; an evaporator 10 fixedly connected to the outer surface of the inlet pipe 20; an outer shell 1 fixedly connected to the outer surface of the evaporator 10; an outlet pipe 19 fixedly connected to the inner wall of the evaporator 10; an outlet pipe 19 fixedly connected to the inner wall of the compressor 6; a warming pipe 5 fixedly connected to the inner wall of the condenser 4; a warming pipe 5 fixedly connected to the inner wall of the compressor 6; and a cold outlet pipe 2 fixedly connected to the inner wall of the condenser 4, which is fixedly connected to the inner wall of the throttling valve 3. The above mechanism enables the medium to absorb heat through evaporation in the evaporator 10 and release heat through condensation in the condenser 4.

[0025] When the heat pump is working, the medium absorbs heat by boiling at low pressure in the evaporator 10, and enters the compressor 6 through the outlet pipe 19. In the compressor 6, the medium is boosted in energy, and then enters the condenser 4 through the warm pipe 5. In the condenser 4, the medium condenses and releases heat, which raises the temperature of the structure where the condenser 4 is located. After condensation, the medium enters the throttling valve 3 through the cold outlet pipe 2 for pressure and temperature reduction. Then, the medium enters the evaporator 10 through the inlet pipe 20 for the next round of operation.

[0026] A defrost pipe 8 is fixedly connected to the inner wall of the heating pipe 5. The defrost pipe 8 is fixedly connected to the inner wall of the outer shell 1. A defrost pump 7 is fixedly connected to the inner wall of the inner shell 18. The above mechanisms are used to pump heating air into the outer shell 1. Several closing mechanisms 9 are rotatably connected to the inner wall of the outer shell 1. The closing mechanism 9 consists of a hinge 14, a drive wheel 12, and a rotating shaft 21, and is used to close the outer shell 1. The rotating shaft 21 is rotatably connected to the inner wall of the outer shell 1. The hinge 14 is fixedly connected to the outer surface of the rotating shaft 21, and the drive wheel 12 is fixedly connected to the outer surface of the rotating shaft 21. The above mechanisms work together to open the hinge 14. The mechanism is used to transmit and synchronize the movement of the drive wheels 12; a belt 13 is fixedly connected to the outer surface of the drive wheel 12, and several drive wheels 12 are connected by the belt 13; a closed motor 15 is fixedly connected to the inner wall of the chamber shell 1, a drive wheel 16 is fixedly connected to the outer surface of the output end of the closed motor 15, and a driven wheel 17 is fixedly connected to the outer surface of the rotating shaft 21; the drive wheel 16 and the driven wheel 17 are connected by transmission; the mechanism is used to drive the hinge 14 to move; a temperature sensor 11 is fixedly connected to the outer surface of the evaporator 10 to detect the temperature inside the chamber shell 1.

[0027] Temperature sensor 11 detects the temperature inside the outer casing 1. When the temperature is too low, defrost pump 7 operates, pumping the high-temperature gas output from compressor 6 to the heating pipe 5 into the interior of outer casing 1 through defrost pipe 8. Simultaneously, motor 15 is activated, driving drive wheel 16 to rotate. Driven wheel 16 drives driven wheel 17 to rotate, driven wheel 17 drives shaft 21 to rotate, shaft 21 drives hinge 14 and drive wheel 12 to rotate, drive wheel 12 drives belt 13 to move, belt 13 then drives another drive wheel 12 to rotate, which in turn drives another hinge 14 to rotate synchronously. After several hinges 14 rotate, they cooperate to seal outer casing 1, reducing the impact of outdoor temperature on evaporator 10. At the same time, the hot gas introduced by defrost pipe 8 heats the interior of outer casing 1, ensuring the temperature of the medium and performing defrosting.

[0028] Working principle: When the heat pump is working, the medium absorbs heat by boiling at low pressure in the evaporator 10, and then enters the compressor 6 through the outlet pipe 19. In the compressor 6, the medium undergoes energy enhancement, and then enters the condenser 4 through the warm pipe 5. In the condenser 4, the medium condenses and releases heat, thus raising the temperature of the structure where the condenser 4 is located. The condensed medium enters the throttling valve 3 through the cold outlet pipe 2 for pressure and temperature reduction, and then enters the evaporator 10 through the inlet pipe 20 for the next cycle of operation. At the same time, the temperature sensor 11 detects the temperature inside the outer casing 1. When the temperature is too low, defrosting is initiated. Pump 7 operates, pumping the high-temperature gas output from compressor 6 into the heating pipe 5 through defrost pipe 8 into the interior of the outer casing 1. Simultaneously, motor 15 is closed, driving drive wheel 16 to rotate, which in turn drives hinge 14 and drive wheel 12 to rotate. Drive wheel 12 drives belt 13 to move, which in turn drives other hinges 14 to rotate synchronously. After several hinges 14 rotate, they work together to seal the outer casing 1, reducing the impact of outdoor temperature on evaporator 10. At the same time, the hot gas introduced by defrost pipe 8 heats the interior of outer casing 1, ensuring the temperature of the medium and performing defrosting.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
