Description

Technical Field

[0001] The utility model relates to the technical field of heat pumps, in particular to a heat pump that is easy to maintain. Background Art

[0002] The heat pump is mainly composed of four parts: evaporator, compressor, condenser and throttling device. It absorbs and releases heat through the state changes of the medium in the internal pipeline, and the heat pump filter mainly filters the refrigerant medium inside it.

[0003] According to a publicly disclosed heat pump filter that is easy to maintain (announcement number: CN217737597U), two metal reinforcement hoops are provided on the outside of the filter body in the above application, and the metal reinforcement hoops are fixedly connected to the outer wall of the filter body. A number of reinforcing ribs evenly spaced are connected between the two metal reinforcement hoops, and the reinforcing ribs are fixedly connected to the metal reinforcement hoops, which is convenient for the installation and maintenance of the internal filter screen.

[0004] However, in actual use of the above equipment, when installing and inspecting the internal filter, the inlet and outlet valves at both ends need to be closed, and then the bolts are removed to remove the filter in the pipeline. Finally, the filter can be inspected, which greatly increases the overall installation and disassembly time, resulting in the problem of low work efficiency. In view of this, we propose a heat pump that is easy to maintain. Utility Model Content

[0014] 2. The heat pump, which is easy to maintain, is installed by turning the knob to rotate the rotating tooth column.
