DETAILED DESCRIPTION

[0016] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0017] like Figure 1-2 As shown, a buffer water tank for a central air-conditioning water system includes a box body 1, a water storage tank 2 is arranged inside the box body 1, a water outlet pipe 3 and an exhaust valve 4 are arranged at the upper end of the water storage tank 2, an expansion tank 5, a sewage outlet 6, a water supply valve group 7, a pressure differential bypass valve 8 and a return pipe 9 are arranged at the lower end of the water storage tank 2, the water outlet pipe 3, the exhaust valve 4, the expansion tank 5, the sewage outlet 6, the water supply valve group 7, the pressure differential bypass valve 8 and the return pipe 9 are all connected with the water storage tank 2, and also include an intermediate pipe 10, a water collection tray 11 is provided at the inner bottom of the box body 1, and an external interface 12 is provided at the lower end of the water collection tray 11.

[0018] The buffer water tank is used in a central air conditioning water system. The intermediate pipe 10 has an upper port and a lower port. The outlet pipe 3 and the upper port of the intermediate pipe 10 are respectively connected to the water inlet and the water outlet in the indoor unit water system pipeline. The lower end of the intermediate pipe 10 and the return pipe 9 are respectively connected to the water inlet and the water outlet in the outdoor host water system pipeline. The water tank 2 and each pipeline connected thereto are filled with water. The outdoor host heats the water in the water system pipeline passing through it. The heated water enters the water tank 2 through the return pipe 9. The heated water in the water tank 2 passes through the outlet pipe 3. The water enters the water system pipeline of the indoor unit, and the fan contained in the indoor unit blows air to the pipeline, so that the blown air is warm air, achieving the purpose of heating the room with warm air. The water that has been cooled by the blowing enters the intermediate pipe 10 through the upper end of the intermediate pipe 10, and is then transmitted to the water system pipeline of the outdoor host through the lower end of the intermediate pipe 10. This part of water is heated again by the outdoor host so that the heated water can continue to be discharged into the water storage tank 2 through the return pipe 9. The flow of water in the water circulation system is controlled by the corresponding pump, and the pump is set in the water system pipeline of the indoor unit or the outdoor unit.

[0019] The exhaust valve 4 is used to quickly discharge the gas in the water tank 2 to protect the equipment; the expansion tank 5 plays the role of accommodating expanded water, balancing the water volume and pressure, avoiding frequent water replenishment by the automatic water replenishment valve, and also plays the role of protecting the equipment; the sewage outlet 6, the sewage outlet 6 is used to discharge the sewage in the water tank 2, including scale and sewage after cleaning, etc.; the water replenishment valve group 7, the water replenishment valve group 7 is connected to an external water source, which is convenient for timely replenishing water into the water tank 2; the pressure differential bypass valve 8, which relies on the pressure of the pipeline network itself to work, keeps the pressure difference at both ends of the valve relatively constant, and protects the equipment from damage; the water accumulation tray 11, the water accumulation tray 11 is used to receive the sewage discharged from the sewage outlet 6, and the external interface 12 at the lower end of the water accumulation tray 11 is connected to the external sewage pipe so that the sewage in the water accumulation tray 11 can be discharged in time. At the same time, the water accumulation tray 11 is also used to receive condensed water that may be generated on the pipe wall above it.

[0020] Since the exhaust valve 4, the expansion tank 5, the water supply valve group 7, and the pressure differential bypass valve 8 are all conventional and commonly used components in the air conditioning water system, their specific principles and structures are not described in detail here.

[0021] Furthermore, a partition 13 is provided inside the box body 1, and the water tank 2 is located above the partition 13. The expansion tank 5, the sewage outlet 6, the water supply valve group 7, the pressure differential bypass valve 8 and the return pipe 9 all pass through and extend to the bottom of the partition 13. The partition 13 is used to support the water tank 2, so that the expansion tank 5, the water supply valve group 7, the pressure differential bypass valve 8 and other components can be installed below the water tank 2.

[0022] Furthermore, the outer surface of the water tank 2 is provided with a heat-insulating layer 14 to keep the water in the water tank 2 warm. The heat-insulating layer 14 may be heat-insulating cotton or heat-insulating foam material.

[0023] Furthermore, the intermediate pipe 10 passes through the water tank 2. Since the intermediate pipe 10 directly passes through the water tank 2, it can reduce space occupation, facilitate reducing the thickness of the box body 1, and facilitate subsequent installation.

[0024] Furthermore, a hanging plate 15 with a through hole is symmetrically provided on the upper end of the box body 1, and a hook is preset on the wall. The buffer water tank is hung on the wall through the cooperation between the hanging plate 15 and the hook.

[0025] Furthermore, a detachable panel 16 is provided on one side of the box body 1, which is beneficial to protecting the components in the box body 1 and improving the aesthetics of the device.

[0026] This type of buffer water tank can integrate multiple valves, pipes and other components into a box body 1, thereby improving the integration of the buffer water tank and avoiding the trouble of on-site installation due to complicated parts. It has the advantages of simple installation, ease of use and time saving. At the same time, the buffer water tank has the characteristics of pressure stabilization, exhaust, sewage discharge, pressure relief and sufficient water replenishment, and through the pressure differential bypass valve 8, it can reduce the frequent start-up of the main unit and achieve the effect of efficient defrosting of the main unit.

[0027] In the description of this utility model, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.
