[0024] The water tank module 30 of the utility model realizes precise control and efficient operation of water flow in 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 water mixing valve 37. The air conditioner host 10 connection pipeline one is directly connected to the use terminal connection pipeline one through the three-way pipe 32, and high-temperature water or low-temperature water can be directly delivered to terminal devices such as the water-air heat exchange type terminal 20, without the need for water mixing treatment of the water storage space 310. This design simplifies the water flow path, reduces heat loss and temperature instability, and significantly improves 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, isolates the air conditioner host 10 from the terminal load, and makes the host run more stably and is not affected by load fluctuations.

The second pump body 34 is arranged on the air conditioner main machine 10 connecting pipeline two, and is used for regulating and controlling the water flow circuit between the air conditioner main machine 10 and the water storage space 310, so that the operation load of the main machine is optimized, and the circulating efficiency of the cold and hot water is improved. The water-air heat exchange type end 20 connecting pipeline two is communicated with the pipeline in the water storage space 310 of the air conditioner main machine 10 connecting pipeline two, and forms an efficient water circulation circuit. Specifically, after the cold water or the hot water releases cold or heat through the water-air heat exchange type end 20, the backwater is delivered to the pipeline in the water storage space 310 through the water-air heat exchange type end 20 connecting pipeline two, and is further delivered to the air conditioner main machine 10 connecting pipeline two, and then is returned to the air conditioner main machine 10 for re-refrigeration or heating treatment.

The third pump body 35 is used for driving the cold and hot water to be delivered from the water storage space 310 to the radiation heat transfer system 40, and provides stable flow support. The constant temperature water mixing valve 37 adjusts the water temperature in real time, so as to ensure that the water temperature delivered to the radiation heat transfer system 40 meets the refrigeration or heating demand. The extension pipeline one 60 is further arranged on the radiation heat transfer system connecting pipeline one 55, and through the extension pipeline one 60, the extension pipeline one 60 can be directly communicated with the water storage space 310, so as to further enhance the flexibility and adjustment capacity of the water flow. The radiation heat transfer system connecting pipeline two 56 is communicated with the radiation heat transfer system connecting pipeline one 55 through the constant temperature water mixing valve 37, so as to form a backwater regulation and control circuit. The backflow water after use of the radiation heat transfer system 40 enters the radiation heat transfer system connecting pipeline two 56, a part of the hot water enters the constant temperature water mixing valve 37 and the cold water flowing through the extension pipeline two 70 to be tempered, so as to realize cyclic use, and the other part of the hot water returns to the water storage space 310. The constant temperature water mixing valve 37 dynamically adjusts the proportion of the backflow water and 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 operation stability of the system.

[0027] The working principle of the utility model realizes efficient management and flexible regulation and control of cold and hot water through the collaborative operation of the air conditioning mode, the floor heating mode and the radiation mode.

In summer, air conditioning host computer 10 prepares low temperature cold water through air conditioning host computer 10 connecting pipeline one, three -way pipe 32 directly to water and air heat exchange type end 20 connecting pipeline one and finally reaches water and air heat exchange type end 20, for indoor cooling. Water and air heat exchange type end 20 utilize cold water to absorb indoor heat, and after cooling, the water flows into air conditioning host computer 10 connecting pipeline two through water and air heat exchange type end 20 connecting pipeline two again, and then flows back to air conditioning host computer 10 to complete the cooling cycle. In this mode, the role of three -way pipe 32 is crucial. It realizes the decoupling of host and end equipment, avoids the direct influence of load fluctuation on the stability of host operation. At the same time, three -way pipe 32 is also responsible for introducing the excess cold water into water storage space 310 for temperature buffering, ensuring that the system can quickly respond to the end demand when the cold load fluctuation is large. The first pump body 33 is installed between water and air heat exchange type end 20 connecting pipeline one and three -way pipe 32, provides stable water flow power, ensures that the cold water can be quickly and stably delivered to water and air heat exchange type end 20. The second pump body 34 is installed on air conditioning host computer 10 connecting pipeline two, responsible for delivering the backflow water of water storage space 310 back to the host, maintaining the efficient operation of the entire circulating system. When heating in winter, air conditioning host computer 10 prepares high temperature hot water, which is delivered to water and air heat exchange type end 20 through air conditioning host computer 10 connecting pipeline one for indoor heating. Similar to the summer mode, after the high temperature water releases heat in water and air heat exchange type end 20, it flows back to air conditioning host computer 10 connecting pipeline two through water and air heat exchange type end 20 connecting pipeline two, and then returns to air conditioning host computer 10 for reheating.

[0029] The warm mode is designed for winter heating, and through the close cooperation of air conditioning host computer 10, floor heating pipeline, three -way pipe 32, water storage space 310 and various components, the efficient operation of the floor heating system is ensured. In this mode, air conditioning host computer 10 prepares high temperature water through air conditioning host computer 10 connecting pipeline one, and the high temperature water is delivered to radiant heat transfer system connecting pipeline one 55 through three -way pipe 32, enters the floor heating pipeline for indoor heating. The high temperature water in the floor heating pipeline releases heat by radiation heat exchange, causing the indoor temperature to rise uniformly and providing comfortable heating effect. The backflow water after releasing heat enters water storage space 310 through radiant heat transfer system connecting pipeline two 56, and water storage space 310 buffers and adjusts the temperature of the backflow water. The backflow water through water storage space 310 returns to air conditioning host computer 10 through air conditioning host computer 10 connecting pipeline two for reheating, completing the cycle. The second pump body 34 is responsible for maintaining the water flow circulation between water storage space 310 and the host, ensuring the continuous delivery of high temperature water.

[0030] The radiation mode fuses the cooling and dehumidification functions, and through linkage operation of the air conditioner host 10, the water storage space 310, the radiation heat transfer system 40, the three-way pipe 32 and various pipes, a flexible and efficient temperature control experience is provided for the user. In the radiation mode, the air conditioner host 10 prepares cold water through the air conditioner host 10 connecting pipe one, 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, and at the same time, the water in the water storage space 310 is returned to the air conditioner host 10 through the air conditioner host 10 connecting pipe two under the power action of the second pump body 34 for repeated use; in addition, after the cold water passing through the radiation heat transfer system 40 absorbs heat and is warmed up, part of the hot water is returned to the water storage space 310 through the radiation heat transfer system connecting pipe two 56, and part of the hot water mixes with the cold water in the storage space through the constant temperature water mixing valve 37 and the extension pipe two 70, and the mixed hot water at the set temperature is transported to the radiation heat transfer system 40 through the radiation heat transfer system connecting pipe one 55 for heat exchange.
