Description

Technical Field

[0001] The utility model relates to the technical field of heating and ventilation, and in particular to a novel temperature-controlled water pump station. Background Art

[0002] A mixer is a device that provides constant-temperature hot water and regulates water temperature, economically and conveniently achieving temperature control in heating systems. Mixers are widely used in low-temperature floor heating systems under urban centralized heating systems. For example, in floor heating systems, the mixing and cooling process involves mixing high-temperature supply water with a portion of low-temperature return water, converting hot water with a small flow rate and a low temperature gradient into circulating water with a large flow rate and a low temperature gradient. Its primary function is to improve the safety and comfort of floor heating systems, with energy savings being secondary. Traditional pumping stations can only connect to one terminal and output liquid at a single temperature at any one time. For example, if a room requires simultaneous control of central air conditioning and floor heating, multiple mixers would require significant space and increase equipment procurement costs. Furthermore, existing pump control systems struggle to distribute and control circulation based on the system's media temperature and flow rate, resulting in limited temperature regulation and poor performance.

[0003] To address the shortcomings of existing technologies, researchers have conducted extensive research and proposed various solutions. For example, a Chinese patent document discloses a water hub pump station [CN202221350743.8], which includes a liquid supply main and a liquid return main, a first liquid supply port and a four-way pipe assembly connected to the liquid supply main, a port connected to the four-way pipe assembly, a second liquid supply port and a three-way pipe assembly, and a liquid return port connected to the liquid return main. The liquid return main is connected to the port via a three-way pipe assembly, and the four-way pipe assembly and the three-way pipe assembly are provided with valve assemblies for controlling the flow of liquid.

[0004] The above solution has solved to a certain extent the problem in the existing technology that the traditional pump station connection equipment is single and can only output liquid at a single temperature. However, this solution still has many shortcomings, such as: it is difficult to circulate and control according to the temperature and flow of the system medium, the temperature adjustment is relatively simple, and the use effect is poor.

The water supply pipe 23 is connected to the terminal device 6, and a mixed water supply pressure sensor 24 and a water supply pressure sensor 25 are respectively provided on both sides of the water supply pipe 23.

[0025] The low-temperature or high-temperature water provided by the heat source first passes through the energy storage water tank 5 and then enters the water inlet pipe 21. The water inlet temperature sensor 22 detects the water inlet temperature and sends it to the pump station control box 7.

[0026] Obviously, the mixing flow component 4 includes a mixing flow pipe 41 , a three-way proportional regulating valve 42 is provided on the mixing flow pipe 41 , and the upper end of the mixing flow pipe 41 is connected to the water supply pipe 23 via a variable frequency circulating water pump 43 .

[0028] The pump station control box 7 compares the set mixed water temperature with the detected mixed water temperature sensor, issues a control instruction to the three-way proportional regulating valve 42, and adjusts the flow rate of the return water from the return water component 3 to the mixing pipe 41, so that the mixed water reaches the set water outlet temperature.

[0029] The variable frequency circulating water pump 43 is used to pump the mixed water to the terminal device 6 for cooling or heating.

[0030] Furthermore, the return water assembly 3 includes a return water pipe 31 arranged at the upper end of the three-way external wire pipe 44, and the return water pipe 31 is provided with a mixed water return water temperature sensor 32 and a return water pressure sensor 37. The lower end of the three-way external wire pipe 44 is provided with an outlet pipe 33, and the outlet pipe 33 is connected to the above-mentioned energy storage water tank 5.

[0031] Specifically, a return water temperature sensor 34 is provided on the water outlet pipe 33 .

[0032] The temperature of the mixed water is adjusted by controlling the three-way proportional regulating valve 42 according to the set water supply temperature, water inlet temperature and water outlet temperature.
