DETAILED DESCRIPTION

[0017] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0018] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0019] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0020] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0021] Please refer to Figure 1 and 2 As described above, the dual water temperature high-efficiency mixed water control integrated system of the present invention can flexibly adapt to the three working modes of air conditioning, heating and radiation, and realizes the precise control and efficient transmission of hot and cold water through the coordinated operation of the air conditioning host 10, the water tank module 30, the three-way pipe 32, the radiation heat transfer system 40 and the water-to-air heat exchange terminal 20. The air conditioning host 10 prepares high-temperature water or low-temperature water according to actual needs. These waters enter the water tank module 30 through the three-way pipe 32. The three-way pipe 32 plays a decoupling role in the system, effectively isolating the direct coupling between the host and the terminal load, making the system operation more stable. Under the heating demand, the air conditioning host 10 generates high-temperature water, which is regulated by the three-way pipe 32 and transported to the water-to-air heat exchange terminal 20 (such as a floor heating system) or the radiation heat transfer system 40 to provide a stable heating effect for the room. When in cooling demand, the host generates low-temperature water, which is transported to the water-to-air heat exchange terminal 20 or the radiation heat transfer system 40 through the three-way pipe 32 for indoor cooling and dehumidification.

[0022] The interior of the box body 31 is rationally divided into a water storage space 310 and an equipment installation space 311, realizing an organic combination of function and structure. In the water storage space 310, high-temperature water and low-temperature water can be accommodated, and the optimized interlayer design reduces the transfer and confusion of heat, thereby ensuring the stability of the water temperature. The equipment installation space 311 is used to arrange key components such as water pumps, sensors, and controllers to ensure that these devices can be installed and operated compactly and efficiently. This partition design not only improves the utilization rate of the internal space of the box body 31, but also realizes the physical isolation of water storage and equipment operation, avoiding the impact of water vapor or temperature fluctuations on equipment performance during equipment operation. At the same time, the square structure design facilitates the connection and installation of the box body 31 with external equipment, reducing the complexity of engineering construction.

[0023] The air conditioner host 10 is connected to the water storage space 310 through the air conditioner host 10 connecting pipe 1 and the air conditioner host 10 connecting pipe 2, respectively, for the input and return of cold and hot water. The water-air heat exchange terminal 20 is connected to the water storage space 310 through the water-air heat exchange terminal 20 connecting pipe 1 and the water-air heat exchange terminal 20 connecting pipe 2, to achieve the output and return of cold and hot water. The radiation heat transfer system 40 is connected to the water storage space 310 through the radiation heat transfer system connecting pipe 1 55 and the radiation heat transfer system connecting pipe 2 56, and is responsible for the efficient radiation heat exchange of cold and hot water. The design of the entire pipeline assembly 50 is closely combined with the functional requirements of the water storage space 310, which not only ensures the efficient connection between the modules, but also reduces the interference and temperature loss between cold and hot water through scientific pipeline distribution and independent pipeline paths. Through this multi-module, multi-path separate connection method, the system can achieve stable transportation and efficient operation of cold and hot water in each working mode, ensuring the reliability and energy-saving effect of the system.

[0024] The water tank module 30 of the present invention realizes precise control and efficient operation of the water flow inside the system through the scientific arrangement of the first pump body 33, the second pump body 34, the third pump body 35, the water valve 36 and the constant temperature mixing valve 37. The air-conditioning host 10 connection pipe 1 is directly connected to the end connection pipe 1 through the three-way pipe 32. High-temperature water or low-temperature water can be directly transported to the terminal equipment such as the water-to-air heat exchange terminal 20 without the need for mixing water in the water storage space 310. This design reduces heat loss and temperature instability by simplifying the water flow path, significantly improving the overall efficiency of the system. The three-way pipe 32 is arranged in the water storage space 310, which plays a core decoupling role, isolating the air-conditioning host 10 from the end load, making the host operation more stable and not affected by load fluctuations.

[0025] The first pump body 33 is arranged between the terminal connecting pipe 1 and the three-way pipe 32, and is used to drive the water flow to the terminal device to ensure the stability of the water flow under load fluctuations. The second pump body 34 is arranged on the connecting pipe 2 of the air-conditioning host 10, and is used to regulate the water flow loop between the air-conditioning host 10 and the water storage space 310, so as to optimize the operating load of the host and improve the circulation efficiency of hot and cold water. The connecting pipe 2 of the water-air heat exchange terminal 20 is connected to the pipe in the water storage space 310 of the connecting pipe 2 of the air-conditioning host 10, forming an efficient water circulation loop. Specifically, when the cold water or hot water releases cold or heat through the water-air heat exchange terminal 20, the return water is transported to the pipe in the water storage space 310 through the connecting pipe 2 of the water-air heat exchange terminal 20, and further flows to the connecting pipe 2 of the air-conditioning host 10, and then returns to the air-conditioning host 10 for re-cooling or heating. This design optimizes the return water path through the pipes in the water storage space 310, so that the return water of the water-to-air heat exchange terminal 20 can be quickly and efficiently returned to the air-conditioning host 10, avoiding the energy loss and response delay that may be caused by the long return water path in the traditional system.

[0026] The radiation heat transfer system connecting pipe 1 55 and the radiation heat transfer system connecting pipe 2 56 ensure the efficient operation of the radiation heat transfer system 40 through the scientific layout and configuration of functional components. The radiation heat transfer system connecting pipe 1 55 is installed with a third pump body 35 and a constant temperature mixing valve 37, and extends to the water storage space 310, and is connected with the three-way pipe 32, forming a complete hot and cold water supply and reflux system. The third pump body 35 is used to drive the cold and hot water from the water storage space 310 to the radiation heat transfer system 40, providing stable flow support. The constant temperature mixing valve 37 adjusts the water temperature in real time to ensure that the water temperature delivered to the radiation heat transfer system 40 meets the cooling or heating requirements. The radiation heat transfer system connecting pipe 1 55 is also provided with an extension pipe 1 60, through which the extension pipe 1 60 can be directly connected to the water storage space 310, further enhancing the flexibility and regulation ability of the water flow. The radiation heat transfer system connecting pipe 2 56 is connected to the radiation heat transfer system connecting pipe 1 55 through the constant temperature mixing valve 37, forming a return water control loop. The return water after the use of the radiation heat transfer system 40 enters the radiation heat transfer system connecting pipe 2 56, and a part of the hot water enters the constant temperature mixing valve 37 and is temperature-adjusted with the cold water flowing from the extension pipe 2 70 to achieve recycling, and the other part of the hot water returns to the water storage space 310. The constant temperature mixing valve 37 dynamically adjusts the ratio of the return water to the water flow in the water storage space 310, accurately controls the water temperature fluctuation in the radiation heat transfer system 40, and further improves the operating stability of the system.

[0027] The working principle of the present invention realizes efficient management and flexible regulation of hot and cold water through the coordinated operation of air-conditioning mode, floor heating mode and radiation mode.

[0028] In the air-conditioning mode, the present invention realizes efficient operation of summer cooling and winter heating through the coordinated action of the air-conditioning host 10, the water-air heat exchange terminal 20, the three-way pipe 32, the water storage space 310 and various pipes and components. In summer, the air-conditioning host 10 prepares low-temperature cold water and directly transports it to the water-air heat exchange terminal 20 connecting pipe 1 through the air-conditioning host 10 connecting pipe 1 and the three-way pipe 32, and finally reaches the water-air heat exchange terminal 20 for indoor cooling. After the water-air heat exchange terminal 20 absorbs indoor heat with cold water, the cooled water flows into the air-conditioning host 10 connecting pipe 2 through the water-air heat exchange terminal 20 connecting pipe 2, and then flows back to the air-conditioning host 10 to complete the cooling cycle. In this mode, the role of the three-way pipe 32 is crucial. It realizes the decoupling of the host and the terminal equipment, avoiding the direct impact of load fluctuations on the stability of the host operation. At the same time, the three-way pipe 32 is also responsible for introducing excess cold water into the water storage space 310 for temperature buffering, ensuring that the system can quickly respond to terminal demand when the cold load fluctuates greatly. The first pump body 33 is installed between the water-to-air heat exchange terminal 20 connecting pipe 1 and the three-way pipe 32 to provide stable water flow power and ensure that cold water can be quickly and stably delivered to the water-to-air heat exchange terminal 20. The second pump body 34 is installed on the air-conditioning host 10 connecting pipe 2, which is responsible for delivering the return water of the water storage space 310 back to the host to maintain the efficient operation of the entire circulation system. During winter heating, the air-conditioning host 10 prepares high-temperature hot water and delivers it to the water-to-air heat exchange terminal 20 through the air-conditioning host 10 connecting pipe 1 for indoor heating. Similar to the summer mode, after the high-temperature water releases heat in the water-to-air heat exchange terminal 20, it flows back to the air-conditioning host 10 connecting pipe 2 through the water-to-air heat exchange terminal 20 connecting pipe 2, and returns to the air-conditioning host 10 for reheating.

[0029] The warm mode is designed for winter heating. Through the close cooperation of the air-conditioning main unit 10, the floor heating pipe, the three-way pipe 32, the water storage space 310 and various components, the efficient operation of the floor heating system is ensured. In this mode, the air-conditioning main unit 10 prepares high-temperature water through the air-conditioning main unit 10 connecting pipe one, and the high-temperature water is transported to the radiation heat transfer system connecting pipe one 55 through the three-way pipe 32, and enters the floor heating pipe for indoor heating. The high-temperature water in the floor heating pipe releases heat through radiation heat exchange, so that the indoor temperature rises evenly, providing a comfortable heating effect. The return water after releasing heat enters the water storage space 310 through the radiation heat transfer system connecting pipe two 56, and the water storage space 310 buffers and adjusts the temperature of the return water. The return water passing through the water storage space 310 returns to the air-conditioning main unit 10 through the air-conditioning main unit 10 connecting pipe two for reheating to complete the cycle. The second pump body 34 is responsible for maintaining the water flow circulation between the water storage space 310 and the main unit to ensure the continuous delivery of high-temperature water.

[0030] The radiation mode combines cooling and dehumidification functions, and provides users with a flexible and efficient temperature control experience through the linkage operation of the air conditioner main unit 10, the water storage space 310, the radiation heat transfer system 40, the three-way pipe 32 and multiple pipes. In the radiation mode, the air conditioner main unit 10 prepares cold water through the air conditioner main unit 10 connecting pipe 1, and the cold water is transported to the water storage space 310 through the three-way pipe 32 to cool the water in the water storage space 310. At the same time, under the power of the second pump body 34, the water in the water storage space 310 is returned to the air conditioner main unit 10 through the air conditioner main unit 10 connecting pipe 2 for reuse; in addition, after the cold water in the radiation heat transfer system 40 absorbs heat and heats up, part of the hot water flows back to the water storage space 310 through the radiation heat transfer system connecting pipe 2 56, and part of the hot water is mixed with the cold water in the storage space flowing through the constant temperature mixing valve 37 and the extension pipe 2 70, and the hot water mixed into the set temperature is then transported to the radiation heat transfer system 40 through the radiation heat transfer system connecting pipe 1 55 for heat exchange. In addition, the air conditioning mode can be turned on to dehumidify the indoor air.
