Technical Field

[0001] The utility model relates to the technical field of heating, ventilation and air conditioning and water supply equipment, in particular to an integrated double-tank hydraulic module with a heat storage function. Background Art

[0002] With the development of the national economy and the improvement of people's living standards, the application of water system air conditioning has become more and more common. However, there are also many pain points. For example, the hydraulic module structure between the heat pump and the user side is designed to cope with the different hot and cold demands of the user side. Its pipelines are complex, there are many valves and valve parts, the installation occupies a large area and the layout is messy. Such integrated equipment is limited by cost and has not been popular in the past ten years. In view of this actual situation, we plan to develop a hydraulic module that can integrate various pipelines, valves and valve parts and other water components to meet market demand.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] See also Figure 1 The utility model discloses an integrated double-tank hydraulic module with heat storage function. As shown in the figure: it includes a water supply tank 102, an automatic exhaust valve 103, a safety valve 105, a return water tank 110 and a pressure difference bypass valve 114;

[0022] The lower end of the water supply tank 102 is connected to the primary side inlet 100, and a drain port 101 is connected between the water supply tank 102 and the primary side inlet 100; the upper end of the water supply tank 102 is connected to the secondary side outlet 106; the upper end of the return water tank 110 is connected to the secondary side inlet 113, and the lower end of the return water tank 110 is connected to the primary side outlet 107; one end of the pressure difference bypass valve 114 is connected to the water supply tank 102, and the other end is connected to the return water tank 110 (this part can adjust its water flow rate through the pressure difference value of the pressure difference bypass valve 114, so as to protect the water pump and the main unit from insufficient flow); the safety valve 105 is connected to the water supply tank 102 (this part is the automatic overpressure protection function of the system. When the system is over-pressured, the safety valve 105 will automatically open and drain water to protect the equipment on the waterway); the automatic exhaust valve 103 is also connected to the water supply tank 102 (when there is residual gas in the tank body, the automatic exhaust valve 103 will automatically open and exhaust, and will automatically close after the exhaust is completed).

[0023] In the utility model, the pressure difference bypass valve 114 can adopt ACOL, PN10 / DN25 / (0.5-2.5bar); the safety valve 105 can adopt Caleffi, DN15, 5bar; the automatic exhaust valve 103 can adopt German Fieso, DN15.

[0024] In the present invention, one end of the pressure difference bypass valve 114 is connected to the water supply tank 102 through the secondary side outlet 106 , and the other end is connected to the return water tank 110 through the secondary side inlet 113 .

[0025] In the utility model, the water supply tank 102 and the return water tank 110 are connected together by a mounting bracket and further fixed to the wall. In particular, the mounting bracket includes an upper mounting bracket 111 and a lower mounting bracket 108; the main connection method is welding. Due to this structure, the main body part forms an inseparable whole, which serves as the main functional component for water storage. In addition, the water supply tank 102 and the return water tank 110 are also connected with a fixing plate 109 and / or a nameplate frame, which are also further formed into a detachable whole by welding, which serves as the main functional component for water storage.

[0026] In the present invention, a water supply temperature and pressure gauge 104 is provided on the water supply tank 102 , and a return water temperature and pressure gauge 112 is provided on the return water tank 110 .

[0027] The utility model also includes an insulation box made of EPP material and arranged outside the integrated double-tank hydraulic module to prevent the loss of cold and heat and also to prevent freezing in winter.

[0028] When the utility model is used, the running direction of the waterway is as follows:

[0029] like Figure 2The hot and cold water from the heat pump enters the device from the primary side inlet 100, flows through the water supply tank 102, and then flows out from the secondary side outlet 106 to the user side. After the hot and cold water is heat exchanged, it returns from the user side, enters the secondary side inlet 113, flows through the return water tank 110, and then flows back to the heat pump host from the primary side outlet 107, completing a cycle.

[0030] like Figure 3 When the user side has a small demand for cooling and heating, the flow rate decreases and the system supply and return water pressure difference increases, which will cause the pressure difference bypass valve 114 to open automatically, so that part of the fluid flows directly from the water supply tank 102 through the pressure difference bypass valve 114 and flows back to the return water tank 110, forming a short circuit, ensuring the basic flow rate on the primary side, and also protecting the water pump and the main unit from insufficient flow.

[0031] During normal operation, the device also has the functions of an automatic exhaust valve 103 and a safety valve 105. The pressure and temperature of the system operation can be directly read through the water supply temperature pressure gauge 104 and the return water temperature pressure gauge 112.

[0032] When the equipment is installed on site, there is also an EPP insulation box on the outside to prevent the loss of heat and cold and also to prevent freezing in winter.

[0033] When the utility model is used, the integrated double-tank hydraulic module can store at least 30L of water. Sufficient water can protect the heat pump from frequent start and stop, and can also well reduce the risk of ice and cracking of the heat pump plate in the event of a fault.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
