Description

Technical Field

[0002] The existing technology, Chinese patent 202022763261.2, describes an assembled noise reduction cover for an air source heat pump, comprising an air source heat pump body, a front noise reduction plate, a left noise reduction plate, a rear noise reduction plate, a right noise reduction plate, a top cover, and an upper noise reduction plate. The top surface of the base of the air source heat pump body has vertically upward-facing front, left, rear, and right noise reduction plates. These plates are sequentially overlapped to form a noise reduction frame surrounding the air source heat pump body. The end face of the noise reduction frame has an air inlet corresponding to the air inlet of the air source heat pump body. The top surface of the noise reduction frame has a top cover, which is a cavity structure with an open bottom. The upper noise reduction plate is located inside the top cover, and its end face has an exhaust hole corresponding to the air outlet of the air source heat pump body. The top surface of the top cover has symmetrical through holes. The problem is that the noise reduction plates are separate from the heat pump body, resulting in a large volume.

[0003] Water source heat pump units generate broadband noise during operation, primarily from sources such as mechanical vibration noise from the compressor, turbulence noise from fluid flow in pipes, noise generated by the water pump, and high-frequency whistling from the motor. This noise affects the living environment through both airborne and structural propagation, and is particularly noticeable during nighttime operation. Utility Model Content
