Description

Technical Field

[0001] This utility model relates to the field of air source heat pump technology, specifically to an air source heat pump antifreeze device. Background Technology

[0002] An air source heat pump is a device that uses heat energy from the air for heating and cooling. It transfers heat from a low-temperature heat source to a high-temperature heat source through physical or chemical processes, thereby providing functions such as indoor heating, cooling, and hot water supply. An antifreeze device is a device or technology used to protect the air source heat pump system from damage or performance degradation caused by icing or coolant freezing in cold weather conditions.

[0003] A search revealed, for example, a Chinese utility model patent publication number CN219390138U provides an air heat source pump antifreeze device. This device, by setting a locking clamp, can fix the antifreeze mechanism to the outside of the heat source pipe body, and can fix both ends of the heat source pipe body, facilitating the installation or removal of the antifreeze mechanism. It also offers high stability after installation. However, this device has certain drawbacks; it can only protect the heat source pipe from the cold and cannot protect the air heat source pump as a whole. This may cause the evaporator and other components inside the air heat source pump to have their service life affected by cold weather. Therefore, an air heat source pump antifreeze device is proposed to solve the above problems. Utility Model Content

[0006] The antifreeze assembly includes an insulation box, which is fixedly installed on the front surface of the insulation frame. A heating box is fixedly installed on the inner bottom wall of the insulation box. A blower is fixedly installed on the top of the heating box. An air inlet pipe is fixedly installed on the right side of the blower. An air inlet plate is fixedly installed at the other end of the air inlet pipe.

[0008] Furthermore, an air duct is fixedly installed on the front wall of the heating box, and the air duct passes through the front wall of the insulation box and extends to the outside of the insulation box.

[0009] Furthermore, the air inlet plate is fixedly installed on the inner right wall of the insulation frame, and the circulating liquid pump is connected to the liquid storage tank through a pipeline.

[0010] Furthermore, the liquid storage tank is internally equipped with three sets of spiral resistance wires, and the circulating heat conduction pipe has a coiled structure and is attached to the rear surface of the heat conduction wire mesh.

[0011] Furthermore, a return pipe is fixedly installed at the end of the circulating heat conduction pipe away from the liquid outlet pipe, and the end of the return pipe away from the circulating heat conduction pipe penetrates the inner wall of the liquid storage tank and extends into the interior of the liquid storage tank.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 An air source heat pump antifreeze device in this embodiment includes a base 1, an insulation frame 2 fixedly installed on the top of the base 1, an air source heat pump body 3 disposed inside the insulation frame 2, and antifreeze components 4 disposed on the inner and outer sides of the insulation frame 2.

[0023] The antifreeze component 4 includes an insulation box 401, which is fixedly installed on the front surface of the insulation frame 2. A heating box 402 is fixedly installed on the inner bottom wall of the insulation box 401. A blower 404 is fixedly installed on the top of the heating box 402. An air inlet pipe 405 is fixedly installed on the right side of the blower 404. An air inlet plate 406 is fixedly installed at the other end of the air inlet pipe 405. Several air masks 4 are fixedly installed on the side of the air inlet plate 406 near the air heat source pump body 3. 07. A liquid storage tank 408 is fixedly installed on the top of the heating box 402. A circulating liquid pump 409 is fixedly installed on the top of the liquid storage tank 408. An inlet pipe 410 is fixedly installed on the top of the circulating liquid pump 409. An outlet pipe 411 is fixedly installed on the side of the inlet pipe 410 away from the circulating liquid pump 409. A circulating heat conduction pipe 412 is fixedly installed on the side of the outlet pipe 411 away from the inlet pipe 410. A heat conduction wire mesh 414 is provided on the rear surface of the air heat source pump body 3.

[0024] like Figure 1 As shown, a heating tube 403 is installed, and an external power supply is used to power the heating tube 403, which in turn heats the air inside the heating chamber 402.

[0025] like Figure 1As shown, by setting up an air duct, when the blower 404 is started, the outside air can be drawn into the heating box 402 for heating. The blower 404 then draws the heated air into the air inlet pipe 405 through the pipe.

[0026] like Figure 2 As shown, by setting a spiral resistance wire, powering the spiral resistance wire with an external power source, and heating the antifreeze inside the storage tank 408 through the spiral resistance wire, and by setting a coiled circulating heat-conducting pipe 412 and a heat-conducting wire mesh 414, the air heat source pump body 3 can be heated evenly, thereby maximizing the antifreeze effect.

[0027] like Figure 3 As shown, by setting the return pipe 413, the antifreeze inside the circulating heat pipe 412 can flow into the storage tank 408, so that the antifreeze inside the storage tank 408 can be recycled.

[0028] like Figure 3 As shown, by setting a temperature detector and installing a temperature sensing probe at the bottom of the temperature detector, the temperature detector is connected to the control panel of the external power supply. The temperature value monitored by the temperature sensing probe in real time can be displayed on the control panel, which is convenient for operating the control panel to control the heating temperature. By setting the insulation cover 5, the space inside the insulation frame 2 is sealed, which improves the insulation and antifreeze effect.

[0029] When implementing this procedure, please follow these steps:

[0030] 1) First, start the blower 404 to draw outside air into the heating chamber 402;

[0031] 2) Then, the heated air is delivered to the air inlet plate 406 through the air inlet pipe 405 by the blower 404 and sprayed out through the air mask 407, thereby heating the air inside the insulation frame 2 and achieving the effect of preventing the air heat source pump body 3 from freezing.

[0032] 3) Restart the circulating liquid pump 409 to extract the antifreeze heated by the resistance wire inside the liquid storage tank 408, and send it to the inside of the circulating heat conduction pipe 412 through the cooperation of the liquid inlet pipe 410 and the liquid outlet pipe 411. Through the action of the heat conduction wire mesh 414, the surface of the air heat source pump body 3 is heated, so that the temperature rises and the antifreeze effect is achieved.

[0033] 4) Finally, the antifreeze flows through the return pipe 413 into the interior of the storage tank 408, achieving a circulating heating effect.

[0034] In summary, this air source heat pump antifreeze device, through the installation of antifreeze component 4, and the cooperation of liquid storage tank 408 and circulating liquid pump, enables the heat-conducting wire mesh 414 to uniformly conduct heat to the air source heat pump body 3. Furthermore, through the cooperation of heating box 402 and heating pipe 403, it can heat the outside air and deliver it into the insulation frame 2, further assisting in heat conduction to the air source heat pump body 3. Through these features, the air source heat pump body 3 can be kept warm, ensuring that it can maintain normal operation even in cold weather and will not malfunction due to weather conditions.
