Description

Technical Field

[0001] This utility model relates to the field of water filtration technology, specifically a ground source heat pump with water purification function. Background Technology

[0002] Geothermal heat pump systems, also known as ground source heat pumps, use ground energy as a cooling source for summer cooling and a low-temperature heat source for winter heating. They are systems that provide heating, cooling, and domestic hot water.

[0003] Chinese patent disclosure CN217340485U discloses a water purification device for a ground source heat pump system, comprising a purification box; the left wall of the purification box is connected to the output end of a circulating water pump; an upper drainage pump is located above the purification box, and the purification box is connected to the input end of the upper drainage pump; and a purification chamber is located inside the purification box on the right side. It has a pre-filtration sedimentation and water stratification mechanism. By performing preliminary water treatment, it can reduce the participation of heavier sediments and lighter floating matter in the filtration process, thereby improving the service life of the filter plates and extending the maintenance and cleaning time of the equipment. This solves the problem that current traditional ground source heat pump purification devices have simple purification mechanisms, purify water directly through the filter plates without prior treatment, which easily reduces the service life of the filter plates, affects the purification effect, and increases purification costs.

[0004] However, it still has the following drawbacks: the device uses a purification filter plate to filter the water and a sedimentation plate to collect the settled impurities. However, during water flow, it is difficult for the water to settle in the sedimentation plate. The device must be shut down for a period of time to clean the inside of the sedimentation chamber, and the cleaning process affects the normal operation of the device. To address this problem, we propose a ground source heat pump with water purification function. Utility Model Content
