[0002] In modern building heating, ventilation and air conditioning technology, the ceiling water and floor water temperature control system has the advantages of constant temperature and humidity. Due to its comfort and high energy efficiency, the system is widely used in residential, commercial buildings and industrial environments. Such a system uses high-temperature water for winter heating and low-temperature water for summer cooling and dehumidification to meet the needs of different seasons. Generally, the system includes a refrigeration host, heating equipment, a water tank, a mixing valve, and terminal equipment (such as a dehumidifier and coils), etc.

Moreover, the power of the air compressor is about 300W, with high energy consumption, which has an adverse impact on the experience of indoor users. At the same time, the economy also needs to be improved. Summary of the Invention

For those of ordinary skill in the art, the specific meanings of the above terms can be understood according to specific circumstances.

[0032] As Figure 1 - Figure 4 As shown, the heat pump temperature control system of the present invention includes a heat pump main unit 1, a mixing assembly, a three-way pipe 32, a floor heating coiled pipe 4 and a dehumidifier 2. Through the coordinated operation of the above-mentioned modules, precise control and efficient transmission of cold and hot water are achieved.

[0033] The heat pump host 1 prepares high-temperature water or low-temperature water according to actual needs, and the water enters the water mixing component through the three-way pipe 32.

[0034] When heating is required, the heat pump host 1 generates high-temperature water, which is regulated by the three-way pipe 32 and then transported to the dehumidifier 2 or the floor heating coil 4 to provide a stable heating effect for the room. When cooling is required, the host generates low-temperature water, which is transported to the dehumidifier 2 or the floor heating coil 4 through the three-way pipe 32 for indoor cooling, dehumidification and defrosting.

[0035] The interior of the box 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 heat transfer and confusion are reduced through the optimized interlayer design, thereby ensuring the stability of the water temperature.

[0036] The equipment installation space 311 is used to arrange key components such as water pumps, sensors, controllers, etc., 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 31, but also achieves physical isolation between water storage and equipment operation, avoiding the impact of water vapor or temperature fluctuations on equipment performance during equipment operation.

[0037] The heat pump main unit 1 is connected to the water storage space 310 through the heat pump main unit 1 connecting pipe 1 and the heat pump return pipe 11 respectively, for the input and return of cold and hot water.

[0038] The dehumidifier 2 is connected to the water storage space 310 through a dehumidification water inlet pipe 20 and a dehumidification water return pipe 21 to achieve output and return of cold and hot water.

[0039] The floor heating coil 4 is arranged in several rooms to be used, and is connected to the water storage space 310 through the coil water inlet pipe 40 and the coil water return pipe 400, and is responsible for the efficient radiation heat exchange of hot and cold water.

[0040] This technical solution uses low-temperature water source for dehumidification, separates a water path in the mixed component, and uses the cold water (such as 8 degrees Celsius) introduced by the heat pump host 1 to act on the heat exchanger of the dehumidifier 2 in each room for defrosting, eliminating the need to set up an air compressor for defrosting. Since there is no air compressor inside, energy consumption and noise are reduced, and it is more economical. In addition, the dehumidifier 2 is equipped with a filter screen to achieve the effect of constant temperature, constant humidity and constant cleanliness.

[0041] Among them, the water mixing valve 5 includes a valve body 50, which has a mixing liquid channel 51 and a liquid inlet channel 52, and a sealing member 53 is arranged between the mixing liquid channel 51 and the liquid inlet channel 52. A top rod 54 that can move relative to the valve body 50 is connected to the top of the valve body 50, and a sealing head 55 that can cooperate with the sealing member 53 is arranged at the front end of the top rod 54.

[0042] The valve body 50 is provided with a water outlet end 56 and a water inlet end 57 that are respectively communicated with the liquid mixing channel 51 and the liquid inlet channel 52. According to needs, the relatively high-temperature cold water introduced into the coil inlet pipe 40 can be mixed with the water liquid to be introduced into the dehumidifier 2 before, so that the temperature of the water liquid coming out of the water outlet end 56 rises a little for defrosting use. The adopted water mixing valve 5 controls the moving amount of the ejector rod 54 to change the flow rates of the water liquids at two different water temperatures, so as to achieve the purpose of the expected water temperature.

[0043] Among them, the cross section of the seal 53 is V-shaped.

[0044] The valve body 50 is provided with a water outlet end and a water inlet end that are respectively communicated with the liquid mixing channel 51 and the liquid inlet channel 52.

[0045] By setting the seal 53 with a V-shaped cross section, the seal 53 is pressed tightly in the valve body 50 by the ejector rod 54, and the fit between the sealing head 55 and the seal 53 is closer. The deformation during the cooperation with the sealing head 55 is different from the structure of the ordinary seal 53, avoiding the adverse effects caused by irregular twisting, enhancing the sealing reliability, and not easily damaging each sealing accessory. This design not only has a stable sealing effect but also is durable.

[0046] In addition, the upper part of the ejector rod 54 has a rotating head for adjusting the up and down movement of the ejector rod 54. A connecting part 540 with an I-shaped cross section is arranged between the rotating head and the ejector rod 54. A pin is inserted into the rotating head and extends into the connecting part 540 to form an integral body. After turning the upper rotating head, the movement of the ejector rod 54 is realized.

[0047] The entire pipeline assembly design is closely combined with the functional requirements of the water storage space 310, not only ensuring the efficient connection between modules, but also reducing the interference and temperature loss between cold and hot water through scientific pipeline distribution and independent pipeline paths. Through this multi-module and multi-path separated 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.

[0048] The mixing water component realizes the precise control and efficient operation of the internal water flow of the system through the scientifically arranged first pump body 41, second pump body 42, third pump body 43, water valve and mixing water valve 5. The heat pump outlet pipe 10 is directly connected to the first end-use connection pipe through the three-way pipe 32, and high-temperature water or low-temperature water can be directly transported to end devices such as the dehumidifier 2 without passing through the mixing treatment of the water storage space 310. This design simplifies the water flow path, reduces heat loss and temperature instability problems, and significantly improves the overall efficiency of the system. The three-way pipe 32 is arranged in the water storage space 310, playing a core decoupling role, isolating the heat pump main unit 1 from the end load, making the main unit operate more stably and not affected by load fluctuations.

[0049] The first pump body 41 is arranged between the dehumidification inlet pipe 20 and the three-way pipe 32, used to drive the water flow to be transported to the end device, ensuring the stability of the water flow under load fluctuations.

[0050] The second pump body 42 is arranged on the heat pump return pipe 11, used to regulate the water flow circuit between the heat pump main unit 1 and the water storage space 310, thereby optimizing the operating load of the main unit and improving the circulation efficiency of cold and hot water.

[0051] The first dehumidification return pipe 21 is connected to the pipe of the heat pump return pipe 11 in the water storage space 310, forming an efficient water circulation loop.

[0052] When cold water or hot water releases cold or heat through the dehumidifier 2, the return water is transported through the first dehumidification return pipe 21 to the pipe in the water storage space 310, and further flows to the heat pump return pipe 11, and then returns to the heat pump main unit 1 for re-cooling or heat treatment. This design optimizes the return water path through the pipe in the water storage space 310, enabling the return water of the dehumidifier 2 to quickly and efficiently return to the heat pump main unit 1, avoiding the energy loss and response lag that may be caused by the long return water path in the traditional system.

[0053] The third pump body 43 and the mixing water valve 5 are installed on the coil inlet pipe 40, and it extends to the water storage space 310 and is connected to the three-way pipe 32, forming a complete cold and hot water supply and return system. The third pump body 43 is used to drive the cold and hot water to be transported from the water storage space 310 to the floor heating coil 4, providing stable flow support. The mixing water valve 5 adjusts the water temperature in real time to ensure that the water temperature transported to the floor heating coil 4 meets the cooling or heating requirements.

[0054] The first extension pipe 44 is also arranged on the coil inlet pipe 40. Through this first extension pipe 44, the first extension pipe 44 can be directly connected to the water storage space 310, further enhancing the flexibility and regulation ability of the water flow. The coil return pipe 400 is connected to the coil inlet pipe 40 through the mixing water valve 5, forming a return water regulation loop.

[0055] The return water after the floor heating coil 4 is used enters the coil return water pipe 400. A part of the hot water enters the mixing valve 5 to be temperature-adjusted with the cold water flowing from the second extension pipe 45, realizing circular use, and another part of the hot water returns to the water storage space 310.

[0056] The mixing valve 5 precisely controls the water temperature fluctuation in the floor heating coil 4 by dynamically adjusting the ratio of the return water to the water flow in the water storage space 310, further improving the operation stability of the system.

[0057] In the air-conditioning mode of the present invention, through the cooperative action of the heat pump main unit 1, the dehumidifier 2, the three-way pipe 32, the water storage space 310, and various pipelines and components, the efficient operation of summer refrigeration and winter heating is achieved.

[0058] In summer, the heat pump main unit 1 prepares low-temperature cold water and directly transports it to the dehumidification water inlet pipe 20 through the first connecting pipe of the heat pump main unit 1 and the three-way pipe 32, and finally reaches the dehumidifier 2 for indoor cooling or dehumidification.

[0059] After the dehumidifier 2 absorbs the indoor heat with the cold water, the cooled water flows into the heat pump return water pipe 11 through the first dehumidification return water pipe 21 and then flows back to the heat pump main unit 1 to complete the cooling cycle. In this mode, the role of the three-way pipe 32 is crucial. It realizes the decoupling of the heat pump main unit 1 and the terminal equipment, avoiding directly affecting the operation stability of the main unit due to load fluctuations. At the same time, the three-way pipe 32 is also responsible for introducing the excess cold water into the water storage space 310 for temperature buffering to ensure that the system can quickly respond to the terminal demand when the cooling load fluctuates greatly.

[0060] The first pump body 41 is installed between the dehumidification water inlet pipe 20 and the three-way pipe 32 to provide stable water flow power to ensure that the cold water can be quickly and stably transported to the dehumidifier 2.

[0061] The second pump body 42 is installed on the heat pump return water pipe 11 and is responsible for transporting the return water of the water storage space 310 back to the main unit to maintain the efficient operation of the entire circulation system.

[0062] When heating in winter, the heat pump main unit 1 prepares high-temperature hot water and transports it to the dehumidifier 2 through the heat pump outlet pipe 10 for indoor heating. Similar to the summer mode, after the high-temperature water releases heat in the dehumidifier 2, it flows back into the heat pump return water pipe 11 through the first dehumidification return water pipe 21 and returns to the heat pump main unit 1 for reheating.

[0063] The heating mode is specially designed for winter heating. Through the close cooperation of the heat pump main unit 1, the floor heating pipeline, the three-way pipe 32, the water storage space 310, and each component, the efficient operation of the floor heating system is ensured. In this mode, the heat pump main unit 1 prepares high-temperature water through the heat pump outlet pipe 10, and the high-temperature water is transported to the coil inlet pipe 40 through the three-way pipe 32 and enters the floor heating pipeline for indoor heating.

[0064] The high-temperature water in the floor heating pipes releases heat through radiation heat transfer, causing the indoor temperature to rise evenly and providing a comfortable heating effect. The return water after releasing heat enters the water storage space 310 through the coil return pipe 400, and the water storage space 310 buffers and regulates the temperature of the return water. The return water passing through the water storage space 310 returns to the heat pump main unit 1 through the heat pump return pipe 11 for reheating to complete the cycle.

[0065] The second pump body 42 is responsible for maintaining the water flow circulation between the water storage space 310 and the main unit, ensuring the continuous delivery of high-temperature water.

[0066] The radiation mode integrates cooling and dehumidification functions. Through the coordinated operation of the heat pump main unit 1, the water storage space 310, the floor heating coil 4, the three-way pipe 32 and various pipes, it provides users with a flexible and efficient temperature control experience.

[0067] In the radiation mode, the heat pump main unit 1 prepares cold water through the heat pump outlet pipe 10. 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 action of the second pump body 42, the water in the water storage space 310 is returned to the heat pump main unit 1 through the heat pump return pipe 11 for reuse;

[0068] In addition, after the cold water passing through the floor heating coil 4 absorbs heat and warms up, a part of the hot water returns to the water storage space 310 through the coil return pipe 400. A part of the hot water is mixed with the cold water in the storage space flowing through the mixing valve 5 and the extension pipe two 45. The mixed hot water with a set temperature is then transported to the floor heating coil 4 through the coil inlet pipe 40 for heat exchange. In addition, the air conditioning mode can be turned on at the same time to dehumidify the indoor air.

[0069] The refrigeration functions of the dehumidifier 2 and the heat pump main unit 1 cooperate to adjust the temperature and dehumidify, playing a synergistic effect, being energy-saving, simple in structure and convenient to install; it has a good effect on ensuring indoor comfort in case of low-temperature and high-humidity climates such as the return of south wind and plum rain days.

[0070] The number of dehumidifiers 2 is multiple, and they are respectively arranged in the same or different rooms.

[0071] The dehumidifier 2 also has a filter screen and a water receiving tray. By setting the filter screen, impurities in the air in the room can be filtered, so that the entire temperature control system achieves the purpose of constant temperature, constant quietness and constant cleanliness. The water liquid melted after the dehumidifier 2 defrosts is led to the water receiving tray through a specially designed pipe, which is convenient for subsequent centralized dumping treatment. The water receiving tray adopts a pull-out connection method. Condensate can also be drained to the sewer through a dedicated drain pipe.

[0072] In addition, by using a water separator to replace the above-mentioned water mixing component, part of the cold water from the heat pump main unit 1 can be directed to the dehumidifier 2, and the water liquid after defrosting is further directed to the floor heating coil 4, without flowing back into the box body 31 through the dehumidification return pipe 21. Through the above-mentioned water separator, the water liquid is directly introduced into each room.

[0073] It should be noted that the dehumidifier 2 not only has the function of dehumidification, but mainly functions to lower the temperature. Only the air compressor is removed, and other functions are retained.

[0074] The placement position of the dehumidifier 2 can be adjusted specifically according to room and construction requirements. The placement position shown in the figure is an example and is not specifically limited here.

[0075] As Figure 4 shown, in this embodiment, each room can also be configured in the form of double coils. The water liquid separately led out by the water mixing component or the water separator is used to defrost the dehumidifier 2, and is introduced into the newly configured floor heating coil through the dehumidification return pipe 21, and then flows back to the water mixing component or the water separator through the dehumidification return pipe 210, while the inlet / return path of the pipeline of the other group of floor heating coils 4 remains unchanged.

[0076] For example, if the water temperature coming out of the water mixing component or the water separator is between 10 degrees and 15 degrees, after entering the dehumidifier 2, it defrosts and cools down. The water liquid coming out of the dehumidifier 2 is about 15 degrees to 20 degrees, and then this water liquid is led to the newly configured floor heating coil 4 to assist in cooling the room again, and jointly cools the room with the original floor heating coil 4. The above configuration method can play an auxiliary cooling role and has the effect of reducing energy consumption.

[0077] In addition, it should be noted that in this system, it is necessary to insulate each pipeline to reduce energy consumption. The insulation materials for wrapping the pipeline and the construction methods are conventional technologies in this field and will not be elaborated here.

[0078] The above are only embodiments of the present invention. Common knowledge such as specific structures and characteristics known to the public in the solution is not described in detail here. Those of ordinary skill in the art know all the common technical knowledge in the technical field to which the invention belongs before the application date or the priority date, can know all the existing technologies in this field, and have the ability to apply the conventional experimental means before this date. Those of ordinary skill in the art can, under the inspiration given in this application, combine their own abilities to improve and implement this solution. Some typical well-known structures or well-known methods should not become an obstacle for those of ordinary skill in the art to implement this application. It should be pointed out that for those skilled in the art, without departing from the structure of the present invention, several deformations and improvements can still be made, and these should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicality of the patent.
