Description

Technical Field

[0001] The utility model belongs to the technical field of heat pump pipeline antifreeze, and in particular relates to an air source heat pump antifreeze device. Background Art

[0002] A heat pump is a device that uses a small amount of high-quality energy (such as electricity) to transfer heat from a low-temperature heat source to a high-temperature heat source, just like a pump can transfer water from a low place to a high place. As the name implies, an air source heat pump uses air as a heat source, transferring heat from outdoor air to indoor air in winter and transferring indoor heat to the outdoors in summer. Current products mainly include household air source heat pump air conditioners, commercial air source heat pump air conditioning units, and heat pump hot and cold water systems; however, the pipes used to conduct heat sources in existing air heat source pumps (i.e., the heat source pipe body in this application) are all exposed to the outside, so when in use, that is, when the heat source pipe body is transferring and conducting air heat sources, heat will be lost in the pipe, affecting the effect of heat source conduction.

[0003] The patent with application number 202320861157.8 discloses an air source heat pump antifreeze device, including an air heat source pump main body, a support frame is installed on the outside of the air heat source pump main body, a heat source pipe body is provided on one side of the air heat source pump main body, and an antifreeze mechanism is wrapped on the outside of the heat source pipe body, and the antifreeze mechanism includes a fluff layer that fits the outer wall of the heat source pipe body, the outer surface of the fluff layer is provided with an insulation layer, and the outer surface of the insulation layer is provided with a waterproof layer; the outside of the antifreeze mechanism is provided with a locking clamp for locking the antifreeze mechanism; the waterproof layer can prevent water from entering and damaging the insulation layer and the fluff layer, affecting the use effect of the insulation layer and the fluff layer; and the setting of the locking clamp can fix the antifreeze mechanism to the outside of the heat source pipe body, and can fix both ends of the heat source pipe body, so as to facilitate the installation or disassembly of the antifreeze mechanism.

[0004] The above technical solution clamps the two ends of the antifreeze mechanism by the bolts and nuts on the locking clamp, and presses the opening on the antifreeze mechanism by the pressure plate. Firstly, due to the lack of sealing between the pressure plate and the antifreeze mechanism, the waterproof layer and the fluff layer that are not squeezed by the locking clamp are prone to loosening, resulting in poor thermal insulation effect. Secondly, the bolts and nuts are prone to rust when used outdoors for a long time, which affects the disassembly efficiency of the antifreeze mechanism. Utility Model Content
