Description

Technical Field

[0001] This utility model relates to the technical field of air temperature regulation equipment, and in particular to a winter air supply air conditioner antifreeze device. Background Technology

[0002] Traditional air conditioning systems often fail to adequately consider the mixing of hot and cold air during design. During operation, the airflow organization inside the outdoor unit is not optimal, allowing cold air from the bottom to blow directly onto the coils. This causes a sharp drop in temperature in certain areas of the coils, creating localized low-temperature zones. Even if the overall ambient temperature monitored by the air conditioning system meets the preset standard, the existence of these localized low-temperature zones still exposes the coils to a high risk of freezing.

[0003] In addition, the external environment of the air conditioner's outdoor unit coil is harsh when the temperature is low in winter. Water vapor in the outdoor air easily condenses into frost when it encounters the low-temperature coil. Over time, the frost layer accumulates and eventually develops into ice. At the same time, in heating mode, the outdoor unit coil acts as an evaporator, and the refrigerant inside absorbs heat to evaporate. This further lowers the surface temperature of the coil, exacerbating the frost and ice formation. Once the coil freezes, it will not only affect the heating efficiency of the air conditioner and increase energy consumption, but may also damage the air conditioning equipment in severe cases.

Detailed Implementation

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figures 1-6 As shown, the present invention provides a winter air-conditioning antifreeze device, including a heating circulator 1 and a heat dissipation copper pipe 2. The heating circulator 1 is fixedly installed inside the outdoor unit housing of the air conditioner, and the heat dissipation copper pipe 2 is coiled in multiple heat dissipation fins inside the outdoor unit housing of the air conditioner. The heating circulator 1 also includes a protective shell 3. A main controller 4 is fixedly installed on the outside of the protective shell 3. A thermostat 5 is also fixedly installed on the protective shell 3 above the main controller 4, and the thermostat 5 is electrically connected to the main controller 4 through a connecting wire. A heating cover 6 is fixedly installed inside the protective shell 3. A circulation pump 7 is also fixedly installed inside the protective shell 3 above the heating cover 6, and the circulation pump 7 is electrically connected to the main controller 4 through a connecting wire. An inner pipe 8 is fixedly installed inside the heat dissipation copper pipe 2.

[0024] like Figures 3-4As shown, a heating resistance wire 10 is fixedly installed on the outside of the heating cover 6, and the heating resistance wire 10 is wound around the outer contour of the heating cover 6. The two ends of the heating resistance wire 10 are electrically connected to the main control board inside the temperature controller 5. One end of the circulation pump 7 is fixedly installed with a liquid inlet 11. A heating tube 13 is inserted inside the heating cover 6, and the outer surface of the heating tube 13 is coated with thermal conductive silicone grease. One end of the heating tube 13 is fixedly connected to one end of the circulation pump 7, and the other end of the heating tube 13 is fixedly installed with a liquid outlet 12. The heating tube 13 is positioned and installed inside the heating cover 6. Through the cooperation of the temperature controller 5 and the heating resistance wire 10, the medium flowing through the heating tube 13 can be rapidly heated. Two connecting pipes 9 are fixedly installed on the outside of the heat dissipation copper tube 2, and the connecting pipes 9 are connected to the inner cavity of the heat dissipation copper tube 2. One end of one connecting pipe 9 is fixedly connected to the liquid inlet 11, and the other end of the connecting pipe 9 is fixedly connected to the liquid outlet 12.

[0025] like Figure 2 , Figures 5-6 As shown, multiple first partitions 14 are fixedly connected between the inner tube 8 and the heat dissipation copper tube 2. Multiple second partitions 15 are fixedly connected between the inner tube 8 and the heat dissipation copper tube 2 located between the two connecting pipes 9. Sealing rings 16 are fixedly connected to both ends of the multiple second partitions 15 and the inner tube 8. The inner tube 8 is set inside the heat dissipation copper tube 2, and the refrigerant of the air conditioner can be circulated normally in the inner tube 8 through the second partitions 15 and the sealing rings 16. The cavity between the inner tube 8 and the heat dissipation copper tube 2 is separated by the second partitions 15 and the sealing rings 16, and the heating medium is circulated by the cooperation of the two connecting pipes 9 and the heating circulator 1. The cavity between the heat dissipation copper tube 2 and the inner tube 8, as well as the connecting pipes 9 and the heating pipe 13, are filled with heating medium.

[0026] It should be noted that this utility model is a winter-cooled air conditioner antifreeze device. When the air conditioner is running in winter and the outdoor temperature is low, causing frost to form on the heat dissipation copper pipe 2 of the outdoor unit and some of the refrigerant inside to freeze, the main controller 4 monitors the ambient temperature and refrigerant circulation. If the ambient temperature is too low and the refrigerant inside the heat dissipation copper pipe 2 may freeze, the main controller 4 will activate the thermostat 5. The heating resistance wire 10 wrapped around the outside of the heating cover 6 will be energized and heated under the control of the thermostat 5 to heat the heating tube 13 inside the heating cover 6. Furthermore, since the outer surface of the heating tube 13 is coated with thermally conductive silicone grease, it can absorb heat more efficiently. Then, the circulation pump 7 starts and extracts the heating medium from the cavity between the heat dissipation copper pipe 2 and the inner tube 8 through the liquid inlet 11. After being heated by the heating tube 13, it is sent back to the cavity between the heat dissipation copper pipe 2 and the inner tube 8 from the liquid outlet 12 and circulates. During this process, the heating medium continuously transfers heat to the heat dissipation copper pipe 2, keeping the heat dissipation copper pipe 2 at a certain temperature and preventing the refrigerant from freezing.
