Description

Technical Field

[0001] This utility model belongs to the field of HVAC equipment technology, specifically relating to a five-constant system wall-mounted distribution pump station. Background Technology

[0002] As people's demands for living comfort continue to increase, the five constant systems (constant temperature, constant humidity, constant temperature, constant temperature) have been widely used in modern buildings. The distribution pump station, as the core power and regulation unit of the five constant systems, directly determines the overall system effect and user experience. However, traditional manifolds and mixing components often lack effective insulation or have incomplete insulation. On the one hand, this results in significant heat loss and reduced system energy efficiency during heating; on the other hand, during cooling, condensation easily forms on the surface of the low-temperature water pipes, causing energy loss and increasing energy consumption. Summary of the Invention

[0003] The purpose of this utility model is to address the above-mentioned problems by providing a five-constant system wall-mounted distribution pump station.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a five-constant system wall-mounted distribution pump station, comprising an open-structure pump station outer casing, a mixing component provided on the inner side of the middle of the pump station outer casing, a distribution component connected to both ends of the mixing component, the mixing component comprising a mixing water pump group, and the distribution component comprising a manifold body, the manifold body being connected to both ends of the mixing water pump group, the mixing water pump group being connected to the pump station outer casing through a pump fixing structure, and a distribution station insulation mechanism provided on the outer side of both the mixing water pump group and the outer side of the manifold body.

[0005] In the aforementioned five-constant system wall-mounted distribution pump station, the pump station's outer casing has side plates at both ends, a back plate located between the two side plates on one side, and an opening on the side of the outer casing away from the back plate. An external water receiving tray is located below the outer casing, with one end connected to one of the side plates, and a corresponding water collection inlet located at the lower end of the side plate closest to the external water receiving tray. This open structure and opening greatly facilitate the installation, commissioning, and subsequent maintenance of all internal components without disassembling the entire casing. The external water receiving tray and water collection inlet are important safety features, collecting potential leaks and guiding them out through the water collection inlet, effectively preventing water damage to equipment or walls and improving the system's reliability and safety.

[0006] In the aforementioned five-constant system wall-mounted distribution pump station, the mixing pump unit includes a circulating water pump, which is a variable frequency circulating water pump. One end of the circulating water pump is connected to a three-way proportional regulating valve, and a bypass valve is connected to the lower side of the three-way proportional regulating valve. Temperature sensors, pressure sensors, and flow sensors are connected to the mixing assembly. Compared to traditional fixed frequency pumps, the variable frequency circulating water pump offers significant energy savings. It can steplessly adjust the speed and flow rate according to the actual needs of the system, avoiding energy waste. It also operates more smoothly and with lower noise. The three-way proportional regulating valve, as the core regulating component, can accurately mix high-temperature primary water and low-temperature return water, providing secondary water supply at the set temperature. The bypass valve serves as a system protection and flow regulation valve. When the secondary load decreases suddenly, it provides a bypass path to prevent pump stalling, protect the pump, and stabilize system pressure. The temperature, pressure, and flow sensors provide real-time data feedback for intelligent control, forming the basis for achieving automated and efficient system operation.

[0007] In the aforementioned five-constant system wall-mounted distribution pump station, the circulating water pump has pump connection parts at both ends near the back plate. The pump fixing structure includes a pump fixing plate disposed between the circulating water pump and the back plate. A pump fixing metal part is provided on the outer circumference of the pump connection part and fixedly connected to the end of the pump fixing plate. A back plate connection part is provided at both ends of the pump fixing plate. Several plastic insulating parts are provided between the back plate connection part and the back plate, and the back plate connection part is connected to the back plate by several fixing bolts. The pump fixing plate and the pump fixing metal part provide robust and stable mechanical support, ensuring that the pump will not experience excessive displacement or vibration during operation. The plastic insulating parts are a key design feature for vibration reduction and noise reduction. They form a flexible connection between the pump fixing plate and the back plate, effectively isolating the vibration and noise generated by the pump operation from the wall, avoiding structural sound transmission, and greatly improving the user experience.

[0008] In the aforementioned five-constant system wall-mounted water distribution pump station, the main body of the water distribution manifold at one end of the mixing pump set is the primary water distribution manifold, and the main body of the water distribution manifold at the other end is the secondary water distribution manifold. The end of the three-way proportional regulating valve away from the circulating water pump is connected to the primary water distribution manifold, and the end of the circulating water pump away from the three-way proportional regulating valve is connected to the secondary water distribution manifold. One end of the bypass valve is connected to the primary water distribution manifold, and the other end is connected to the secondary water distribution manifold. A drain and air vent valve is provided below the primary water distribution manifold and near the side plate. The number of primary and secondary water distribution manifolds in the distribution station can be adjusted and matched according to requirements. Furthermore, the installation orientation of the distribution station can be rotated 90° according to site requirements.

[0009] In the aforementioned five-constant system wall-mounted distribution pump station, the insulation mechanism of the distribution station includes a main insulation component installed on the outside of the manifold body and a mixing insulation component installed on the outside of the mixing pump group. Comprehensive insulation is achieved by insulating both the manifold and the mixing component, the two main heat dissipation components. This is crucial for energy saving and condensation prevention, effectively reducing heat loss during hot water transportation and distribution, improving system energy efficiency, and preventing condensation in low-temperature circulation or high-humidity environments. The insulation layer ensures that the surface temperature of the components does not fall below the dew point temperature, preventing condensation and thus preventing dripping, corrosion, and equipment short circuits.

[0010] In the aforementioned five-constant system wall-mounted water distribution pump station, both the primary and secondary water distribution bodies have several axially arranged single-channel water distribution bodies arranged sequentially. These single-channel water distribution bodies are connected sequentially by metal tie rods. Each single-channel water distribution body located above the main body of the water distribution unit is equipped with a manual actuator, while each single-channel water distribution body located below the main body of the water distribution unit is equipped with an automatic actuator. This design allows for flexible adjustment of the number of water channels in the water distribution unit to adapt to different scale requirements, offering strong versatility. The metal tie rods ensure the mechanical strength and sealing of the overall structure.

[0011] In the aforementioned five-constant system wall-mounted distribution pump station, the main insulation component includes several main insulation parts arranged on the outer periphery of the single-channel water distribution body. The primary water distribution body has a main pipe joint insulation part at the end furthest from the mixing pump group, and the secondary water distribution body has a sealing insulation part at the end furthest from the mixing pump group. The segmented main insulation parts match the modular water distributor, allowing for flexible and convenient installation. The main pipe joint insulation part provides specialized insulation for the main pipe interface where heat loss is greatest, paying attention to detail and reducing energy leakage points. The sealing insulation part insulates the ends, demonstrating the integrity and tightness of the insulation, with no dead corners.

[0012] In the aforementioned five-constant system wall-mounted distribution pump station, the mixing and insulation component includes a mixing and insulation inner shell disposed on the side of the mixing pump unit near the back plate, and a mixing and insulation outer shell disposed on the side of the mixing pump unit away from the back plate, which is fitted together with the mixing and insulation inner shell. A mixing and insulation top cover is provided at the upper end of the mixing and insulation outer shell. The mixing and insulation inner shell, the mixing and insulation outer shell, and the mixing and insulation top cover completely enclose the mixing component, resulting in excellent insulation performance.

[0013] In the aforementioned five-constant system wall-mounted distribution pump station, a pump slot corresponding to the circulating water pump is located between the mixing water insulation cover and the mixing water insulation shell, and one end of the pump slot is equipped with a regulating valve slot corresponding to the three-way proportional regulating valve. This demonstrates the precision of the insulation component design, ensuring that the insulation component can perfectly fit with the internal equipment, guaranteeing the insulation effect without affecting the normal operation of the equipment.

[0014] Compared with existing technologies, the advantages of this utility model are: 1. The device provides full-coverage, no-dead-angle insulation for the distribution and mixing components, greatly reducing heat loss during the transmission process, improving the overall system's thermal efficiency, and directly reducing heating costs. At the same time, it ensures that no condensation occurs on the surface of low-temperature components during summer cooling or high humidity conditions, avoiding the risk of water dripping damaging the decoration and causing equipment corrosion, thus ensuring equipment safety.

[0015] 2. Through the design of the water pump fixing structure, the device achieves vibration isolation, effectively isolating the vibration generated by the water pump during operation from propagating through the wall, avoiding annoying low-frequency noise, perfectly meeting the constant and quiet requirements of the five constant systems, and also reducing the potential damage to the building walls caused by long-term vibration.

[0016] 3. This device utilizes a drip tray to provide better hydrophobicity, collects accidentally leaked liquids, and discharges them through the collection port, protecting walls and floors. It is an important safety protection measure and can also protect against potential leaks at pipe connections.

[0017] 4. This device integrates the mixing and distribution components into a single wall-mounted pump station enclosure, making installation and maintenance convenient. The wall-mounted installation method greatly reduces the difficulty of on-site construction and also facilitates subsequent maintenance work. Attached Figure Description

A flow sensor 25, a pressure sensor 27, and a temperature sensor 28 are connected to the mixing assembly 2. Compared with traditional fixed frequency pumps, the variable frequency circulating water pump has significant energy-saving effects. It can steplessly adjust the speed and flow rate according to the actual needs of the system, avoiding energy waste. It also operates more smoothly and with lower noise. The three-way proportional regulating valve 23 is the core regulating component, which can accurately mix the high-temperature primary side and the low-temperature return water, providing secondary side water supply at the set temperature.

The pump fixing plate 41 and the pump fixing metal parts 42 provide robust and stable mechanical support, ensuring that the pump will not experience excessive displacement or vibration during operation. The plastic insulating parts 44 are a key design feature for vibration reduction and noise reduction. They form a flexible connection between the pump fixing plate 41 and the back plate 12, effectively isolating the vibration and noise generated by the pump operation from being transmitted to the wall, avoiding structural sound transmission, and greatly improving the user experience.

At the same time, the installation orientation of the distribution station can be rotated 90° according to the site requirements.

[0032] Combination Figure 5 and Figure 6 As shown, the insulation mechanism 5 of the distribution station includes a main insulation component 51 installed on the outside of the manifold body 31 and a mixing water pump assembly 21 installed on the outside of the mixing water pump assembly 21. Comprehensive insulation is achieved by insulating both the manifold and the mixing water assembly 2, the two main heat dissipation components. This is crucial for energy saving and condensation prevention, effectively reducing heat loss during hot water transportation and distribution, improving system energy efficiency, and preventing condensation in low-temperature circulation or high-humidity environments. The insulation layer ensures that the surface temperature of the components is not lower than the dew point temperature, preventing condensation and thus preventing dripping, corrosion, and equipment short circuits.

[0033] like Figure 7 As shown, both the primary water distribution body 32 and the secondary water distribution body 33 have several axially arranged single-channel water distribution bodies 35. These single-channel water distribution bodies 35 are connected sequentially by metal tie rods 36. Each single-channel water distribution body 35 located above the main body 31 is equipped with a manual actuator 37, while each single-channel water distribution body 35 located below the main body 31 is equipped with an automatic actuator 38. This design allows for flexible adjustment of the number of channels in the water distribution system to adapt to different scales of needs, offering strong versatility.
