[0002] An air source heat pump is an energy-saving device that uses high-level energy to make heat flow from low-level heat source air to high-level heat source. It is a form of heat pump. As the name implies, a heat pump is like a pump, which can convert low-level heat energy that cannot be directly used (such as heat contained in air, soil, and water) into high-level heat energy that can be used, thereby achieving the purpose of saving some high-level energy (such as coal, gas, oil, electricity, etc.). The air source heat pump unit includes a main unit and a water tank. The main unit and the water tank are separately set. The main unit mainly contains compressors, heat exchangers, cooling fans and other components. The main unit is usually directly installed on a cement floor or steel frame, which causes the vibration generated when the main unit is running to be directly transmitted to the hard cement floor or steel frame, thereby generating a lot of noise. In addition, the compressor inside the main unit will generate a lot of noise when running, further increasing the noise generated by the main unit unit. Utility Model Content
