Description

Technical Field

[0001] The utility model relates to the technical field of heat pump units, in particular to a hot water engineering heat pump unit with a noise reduction protection mechanism. Background Art

[0002] Hot water heat pump units mainly use air, groundwater, surface water, etc. as low-temperature heat sources, and extract the heat from these low-temperature heat sources through heat pump technology and convert them into hot water for people to use. This technology is not only energy-saving and environmentally friendly, but also can effectively utilize low-grade thermal energy to achieve energy-saving purposes. The working principle of hot water heat pump units is based on heat pump technology, that is, by consuming a small amount of high-grade energy, heat is caused to flow from low-temperature objects to high-temperature objects, thereby achieving heat transfer and improvement.

[0003] The hot water project heat pump unit will generate a lot of noise when working. Currently, most of the heat pump units are installed in an exposed manner or with a simple assumed protective frame, and their protection performance is low. At the same time, the noise generated cannot be reduced in time, and their use is subject to certain restrictions. In this regard, we design a hot water project heat pump unit with a noise reduction protection mechanism. Utility Model Content
