Description

Technical Field

[0001] This utility model relates to the field of ground source heat pump technology, and in particular to an auxiliary water supply device for ground source heat pumps. Background Technology

[0002] Ground source heat pumps are a type of high-efficiency and energy-saving air conditioning system. They use the earth as a heat source or heat sink and transfer heat from the soil to the room for heating in winter through underground buried pipe heat exchangers. In summer, they release heat from the room into the soil to achieve cooling. This system utilizes shallow underground geothermal resources, which have a relatively stable temperature, making ground source heat pumps highly efficient, more energy-saving than traditional air conditioning systems, and reducing environmental pollution.

[0003] If a closed-loop ground source heat pump leaks, it will threaten the stable operation of the system. Once a leak is discovered, the leak point must be located and repaired as soon as possible. After that, water should be added to maintain the normal operation of the system. The water replenishment operation usually uses an expansion tank to inject water into the system. However, the current expansion tank has a design shortcoming: it lacks a structure for accurately calculating the amount of water to be added. This makes it impossible to accurately control the amount of water to be added. Once too much water is added, it will cause the ground source heat pump system to have excessive pressure, or even cause the circulating water to overflow, affecting the system performance and safety.

[0004] Therefore, in response to the above problems, a new ground source heat pump auxiliary water supply device is proposed. Utility Model Content

[0007] Furthermore, the filtration mechanism includes a positioning seat, a filter seat, and a first filter screen; A positioning seat is connected to the water outlet pipe, and a filter seat is slidably connected inside the positioning seat. The filter seat is U-shaped, and the lower surface of the filter seat is in contact with the inner wall of the water outlet pipe. A first filter screen is bolted to one side of the filter seat.

[0008] Furthermore, a rubber strip that contacts the surface of the filter seat is fixedly connected to the inner wall of the positioning seat.

[0009] Furthermore, a drive seat is fixedly connected to the lower surface of the water outlet pipe, and an electric telescopic rod is symmetrically fixedly installed inside the drive seat. The moving end of the electric telescopic rod is fixedly connected to the filter seat.

[0011] Furthermore, the pore diameter of the second filter screen is larger than that of the first filter screen.

[0012] Furthermore, a rectifier cylinder is fixedly connected to the inner wall of the water outlet pipe, and honeycomb holes are equidistantly opened inside the rectifier cylinder.

[0013] The technical solution provided by this utility model can include the following beneficial effects: In this example, by installing an electromagnetic flow meter and a filtration mechanism, the expansion tank body discharges water from the outlet pipe, the filter seat enters the positioning seat, the lower surface of the filter seat is attached to the inner wall of the outlet pipe, the water passes through the first filter screen to filter impurities, and the filtered water enters the ground source heat pump through the electromagnetic flow meter, the water delivery volume is recorded, and the ground source heat pump is precisely replenished.
