Description

Technical Field

[0001] This application belongs to the field of air source heat pump technology, specifically a defrosting device for air source heat pumps. Background Technology

[0002] A defrosting device for air-source heat pumps effectively prevents frost formation in low-temperature environments, ensuring normal system operation. In cold weather, water vapor in the air condenses into frost on the evaporator, affecting the heat exchange efficiency of the heat pump. The defrosting device can detect frost formation in real time and automatically initiate the defrosting process, ensuring the heating efficiency of the heat pump remains unaffected. Secondly, this device, through its efficient defrosting method, can quickly remove frost from the evaporator, restoring the heat pump's normal heat exchange capacity and reducing the energy efficiency decline caused by frost. Defrosting devices typically have low energy consumption; with proper control, the energy consumed during the defrosting process is minimal, minimizing the impact on the overall energy efficiency of the heat pump system.

[0003] For example, CN221593237U discloses a defrosting device for air source heat pumps, including a frame. A defrosting fan is installed inside the frame. A protective structure is provided at one end of the frame, and an installation structure is provided at the top end of the frame. The installation structure includes a sliding groove located inside the top end of the frame. An installation piece is provided inside the sliding groove. A limit block is fixed to the bottom end of the installation piece, and a second bolt is provided inside the installation piece. By setting up the installation structure, the installation piece can slide inside the sliding groove through the sliding structure between the installation piece and the sliding groove. The limit block limits the bottom end of the installation piece, allowing it to be limited inside the sliding groove. The second bolt further limits the installation piece, enabling the frame to be installed. The sliding of the installation piece makes the frame more flexible during installation, improving the installation flexibility of the defrosting device for air source heat pumps.

[0004] However, in common applications of this technology, it is inconvenient for operators to adjust the defrosting structure on the side of the air source heat pump during operation, thus making it difficult to adjust and use the equipment according to different defrosting needs and reducing its adaptability.

[0014] In a preferred embodiment, the upper end of the defrosting box is provided with a rectangular slot, a snap-fit ​​plate is snapped into the inside of the slot, and a protective mesh plate is fixedly connected to the middle position of adjacent snap-fit ​​plates.

[0015] By adopting the above technical solution, the rectangular slot facilitates the placement of the card plate, thereby making it easier to install the protective mesh plate and use it for protective filtration operations, ensuring the normal operation of the subsequent fan.

[0016] In a preferred embodiment, the upper end of the snap-fit ​​plate is threaded with a fixing screw, and the other end of the fixing screw passes through the snap-fit ​​plate and is inserted into a threaded hole provided in the rectangular snap-fit ​​slot.

[0017] By adopting the above technical solution, the setting of the fixing screw facilitates the fixing of the snap-fit ​​plate in the rectangular slot, thereby facilitating the fixing of the snap-fit ​​plate and the protective mesh plate in operation. The setting of the fixing screw also facilitates the installation and disassembly operations of the workers.

[0018] In a preferred embodiment, a rectangular plate is fixedly connected inside the defrosting box, and a working fan is provided at the lower end of the rectangular plate.
