Description

Technical Field

[0001] This application belongs to the technical field of type, specifically a high-efficiency variable frequency heat pump unit. Background Technology

[0002] A heat pump unit is a device that uses the reverse Carnot cycle principle to transfer heat from a low-temperature heat source to a high-temperature heat source with a small amount of electrical energy. The refrigerant absorbs heat from the low-temperature heat source and evaporates in the evaporator. After being compressed by the compressor, it becomes a high-temperature, high-pressure gas, which releases heat to the high-temperature heat source in the condenser. Then, after being throttled and depressurized by the expansion valve, it re-enters the evaporator for the next cycle.

[0003] For example, patent CN219607426U discloses a high-efficiency air-cooled heat pump unit, including a base, a slide rail mounted on the upper surface of the base, an installation component slidably connected to the upper surface of the slide rail, an organism mounted on the upper surface of the installation component, an exhaust pipe mounted on the upper surface of the organism, fan blades installed inside the exhaust pipe, a connecting rod mounted at one end of the installation component, the installation component connected via the connecting rod, a rack mounted in the middle of the connecting rod, a base column mounted at the bottom of the base, and a rotating shaft rotatably connected inside the base, with a gear mounted in the middle of the rotating shaft. This device, by installing the gear, rack, and installation component inside the base, facilitates the movement of the organism's position, making debugging and adding components to the organism convenient. In use, rotating the rotating shaft causes the gear to move the rack, which in turn causes the installation component to slide on the upper surface of the slide rail, allowing for fine-tuning of the device.

[0004] However, the device does not have a component installed to facilitate maintenance of the fan assembly. When the fan assembly needs maintenance, it cannot be lifted out of the device for maintenance, which causes inconvenience in maintaining the fan assembly. Utility Model Content

An electric telescopic rod drives the connecting plate to move the mounting bracket up and down, allowing the fan assembly to be removed from the device for easy maintenance. A protective net prevents foreign objects from falling into the fan assembly and damaging it. The device employs a combination of a servo motor and fan blades.

[0030] Example:

[0031] Reference Figures 1-3The system includes an outer frame 1, which contains two parts: a frame and an outer shell. The frame serves as the mounting base for the entire device, supporting the equipment installed inside. The outer shell provides a physical protective barrier for the internal components, preventing damage from external objects. A ventilation duct 2 directs external air out of the system and provides a position and support for the fan assembly installed inside the heat pump. A combination of an electric telescopic rod 3 and a connecting plate 4 is used. The electric telescopic rod 3 maintains the main part of the fan assembly and can raise and lower the connecting plate 4 on its upper surface. A cavity area is provided inside the mounting bracket 5 to facilitate airflow within the heat pump, and the outer surface of the mounting bracket 5 provides a position for the fan assembly. The connecting plate 4 is driven by the electric telescopic rod 3. The up-and-down movement of the fixed frame 5 allows the fan assembly to be brought out of the device for easy maintenance.
