Description

Technical Field

[0001] The utility model relates to the field of air conditioning systems, in particular to a room-based temperature and humidity control system. Background Art

[0002] In the design of hospital air conditioning, there are usually some small compartments. Due to odor, infectiousness, process requirements, etc., a fresh air direct current system or a full air system is used. Because each small compartment may have inconsistent heat generation, inconsistent usage time, and different user perceptions of room temperature and humidity, independent rooms are required to be switchable and temperature adjustable. To solve the above problems, some projects even set up dual air conditioning systems, one fresh air system to meet the room air supply and cleanliness requirements, and a circulating air conditioning system for independent room temperature control, which not only increases investment, but also the airflow of the indoor unit interferes with the orderly airflow organization in the room.

[0003] Through literature research, it is found that in the field of comfort air conditioning, the room temperature and humidity can be adjusted by changing the air supply volume in the room. In the prior art, the invention patent "A non-powered variable air volume module" (CN218379837U) discloses a non-powered variable air volume module, which can accurately control the air volume of the system; the invention patent "A variable air volume module for a fresh air system" (CN213454051U) discloses a variable air volume module for a fresh air system, which has a simple structure and reasonable arrangement, is suitable for fresh air systems of different sizes, and can adjust the air volume of the fresh air system according to different needs; the invention patent "Floor air conditioner VAV constant temperature variable air volume modification system" (CN114413450A) discloses a floor air conditioner VAV constant temperature variable air volume modification system, which can automatically adjust the terminal temperature according to the self-temperature sensing conditions, solving the problems of large air volume, high noise and low energy saving in some offices. The above three patents are applicable to conventional comfort air-conditioning areas or areas with no requirements for air supply volume. For hospital clean areas, laboratories or isolation wards, there are strict regulatory requirements for air supply and ventilation times, and the air supply volume is usually a constant value. Therefore, it has no reference significance for achieving variable temperature and humidity control with constant air supply volume in this case.

[0004] In view of this, this application is hereby filed. Utility Model Content

[0041] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0042] In the description of the present invention, it should be noted that the terms "first", "second", "third", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0043] Example

[0044] like Figure 1-2As shown, the embodiment of the utility model provides a compartment temperature control and humidity control system, which is characterized by comprising: an air conditioning component 1, which is configured to perform a cooling operation on air, and waste heat will be generated in the cooling operation (conversely, when the air is heated, waste cold will be generated in the heating operation); an air supply pipe 2, which is connected to the air conditioning component 1, and transports the cooled or heated air to multiple independent spaces; a variable temperature and humidity control component 3, which is arranged on the air supply pipe 2, and the number is multiple, and the specific number can be adjusted according to actual conditions, each variable temperature and humidity control component 3 is used to independently adjust the temperature of the air received in a single predetermined environment, and the humidity is slightly adjusted by temperature adjustment; the variable temperature and humidity control component 3 can use the waste heat generated by the air conditioning component 1 to heat the cooled air (conversely, the air conditioning component 1 can generate waste cold to cool the heated air), that is, the waste heat or waste cold of the air conditioning component 1 can be transferred to the variable temperature and humidity control component 3 by heat conduction, and the cooled or heated air will exchange heat with the waste heat or waste cold in the variable temperature and humidity control component 3, thereby achieving temperature adjustment of each independent space.

[0045] For example, Figure 1 and Figure 3As shown, in Example 1, the variable temperature and humidity control component 3 includes a module box 4, a fluorine coil 5 is arranged in the module box 4, a refrigerant interface 6 is arranged on the module box 4, one end of the refrigerant interface 6 is connected to the refrigerant pipe 7, the refrigerant pipe 7 is connected to the air conditioning component 1, and the refrigerant interface 6 is used to transfer the waste heat or waste cold generated by the air conditioning component 1 to the fluorine coil 5 through the refrigerant pipe 7; the module box 4 is also provided with an interface flange 8, and the interface flange 8 is used to connect the variable temperature and humidity control component 3 to the air supply pipe 2; the refrigerant is arranged in the refrigerant pipe 7. Specifically, the module box 4 is the outer supporting structure of the entire variable temperature and humidity control component 3, which is connected to the air supply pipe 2 through the interface flange 8, so as to ensure the circulation of the air treated by the air conditioner, that is, before the air treated by the air conditioner enters the corresponding independent space, it will pass through the module box 4 and perform heat exchange with the fluorine coil 5 in the module box 4, so as to achieve temperature regulation. For the heat source or cold source of the fluorine coil 5, the refrigerant is circulated and transferred in the fluorine coil 5 and the refrigerant pipe 7 to achieve. More specifically, the refrigerant medium can circulate in the fluorine coil 5 and the refrigerant pipe 7, and the circulation process can be realized by using the compressor compression in the prior art. Since the refrigerant pipe 7 is connected to the air conditioning assembly 1, the waste heat or waste cold generated by the air conditioning assembly 1 will be transferred to the refrigerant (heat transfer) through the refrigerant pipe 7, and the heated refrigerant will be transported to the fluorine coil 5 during the circulation process, and the heat will be transferred to the fluorine coil 5. At this time, the air passing through the module box 4 will exchange heat with the fluorine coil 5, and will be heated or cooled before entering the independent space to achieve temperature regulation. The operator can achieve independent temperature regulation of each independent space by adjusting the working state of the compressor, the refrigerant flow, etc. The system is not only simple to operate and practical, but also utilizes the waste heat or waste cold generated by the air conditioning assembly 1, and has the effect of energy saving and emission reduction. Of course, in other embodiments, the circulating medium can be replaced, and there is no restriction here, as long as the purpose of realizing the circulation of the medium and the heat exchange of the cycle can be achieved.

[0046] For example, in Example 2, Figure 2 and Figure 4As shown, the variable temperature and humidification component 3 includes a module box 4, a water coil 9 is arranged in the module box 4, the water coil 9 is connected to a water pipe 10, the water pipe 10 and the water flow in the water coil 9 can circulate, the water pipe 10 is connected to the air-conditioning component 1, and the waste heat or waste cold generated in the air-conditioning system can be transferred to the water coil 9 through the water flow in the water pipe 10; an interface flange 8 is also arranged on the module box 4, and the interface flange 8 is used to connect the variable temperature and humidification component 3 to the air supply pipe 2. Specifically, the main difference between this embodiment and embodiment 1 is that the fluorine coil 5 is replaced by a water coil 9, the refrigerant pipe 7 is replaced by a water pipe 10, and the medium refrigerant is replaced by water. Similarly, under the action of a water pump, the water flow can be driven to circulate in the water coil 9 and the water pipe 10. Since the water pipe 10 is connected to the air conditioning component 1, the waste heat or waste cold generated in the air conditioning system will be transferred to the water medium through the water pipe 10. The heated water medium circulates under the action of the compressor. When it flows into the water coil 9, the heat will be transferred to the water coil. At this time, the air entering the module box 4 will fully contact the water coil 9, thereby realizing heat exchange and achieving the purpose of regulating the temperature. After the water in the water coil 9 is heat exchanged, it will continue to circulate and continue to absorb the waste heat or waste cold generated in the air conditioning system. It should be noted that the fluorine coil 5 and the water coil 9 provided in embodiment 1 and embodiment 2 are both disc-shaped curved structures, which can increase the contact area between the fluorine coil 5 or the water coil 9 and the cooling air, thereby achieving the purpose of efficient heat transfer and temperature regulation.

[0047] Further, on the basis of Example 1, the air supply pipe 2 includes a main pipe 11 and a plurality of branch pipes 12, the main pipe 11 is connected to the air conditioning assembly 1, and each branch pipe 12 is provided with a variable temperature and humidity control component 3; each variable temperature and humidity control component 3 is connected to a refrigerant branch pipe 13, and each refrigerant branch pipe 13 is connected to the refrigerant pipe 7. Specifically, the main pipe 11 is directly connected to the air conditioning assembly 1, and is responsible for conveying the air treated by the air conditioning to each branch pipe 12, each branch pipe 12 leads to a specific independent space, and each branch pipe 12 is provided with a variable temperature and humidity control component 3 to provide independent air conveyance. Each variable temperature and humidity control component 3 is connected to its own refrigerant branch pipe 13, which is responsible for conveying the refrigerant from the refrigerant pipe 7 to the corresponding variable temperature and humidity control component 3. The refrigerant pipe 7 is the main channel for the flow of refrigerant in the entire system, which conveys the heated or cooled refrigerant to each refrigerant branch pipe 13, and then reaches each variable temperature and humidity control component 3, and then conveys the cooled refrigerant to absorb the waste heat or waste cold generated by the air conditioning assembly 1. In the embodiment of the utility model, each variable temperature and humidity control element 3 can be independently controlled, allowing for more accurate temperature regulation for each independent space. In other embodiments, the system design can increase or decrease the branch pipe 12 and the variable temperature and humidity control element 3 as needed to adapt to different space layouts and regulation requirements. The system is suitable for buildings that need to provide different temperature and humidity conditions for multiple independent spaces, such as hospital clean areas, laboratories or isolation wards, etc. By accurately controlling the air conditions of each space, the overall comfort and energy efficiency can be improved.

[0048] As a preferred embodiment of the utility model, a first control valve 14 is provided on the refrigerant pipe 7 beside the air conditioning assembly 1, and a second control valve 15 is provided on each refrigerant branch pipe 13. The first control valve 14 can control the flow of the refrigerant after absorbing waste heat or waste cold, and adjust the cooling or heating capacity of the entire system. Specifically, according to the needs of the system and the set temperature, the first control valve 14 can be fully opened, partially opened or closed to adjust the flow of the refrigerant. The second control valve 15 controls the flow of the refrigerant flowing to each variable temperature and humidity control component 3 to achieve accurate temperature regulation of each independent space. The second control valve 15 can be independently adjusted according to the needs of each branch pipe 12, allowing customized temperature control for each space. The first control valve 14 and the second control valve 15 are usually automatically managed by the control system, and are adjusted according to the feedback of the temperature sensor and the user's settings. The control system monitors the temperature of each space and adjusts the opening of the first control valve 14 and the second control valve 15 as needed to maintain the required temperature. By accurately controlling the flow of the refrigerant, excessive heating or cooling can be avoided, thereby improving the energy efficiency and energy saving of the system. Of course, a heat exchange mechanism 16 can also be connected to the refrigerant pipe 7. The heat exchange mechanism 16 is configured to dissipate the waste heat or waste cold that does not pass through the first control valve 14. The heat exchange mechanism 16 is used to process the waste heat or waste cold carried by the refrigerant that does not pass through the first control valve 14. It should be noted that the heat exchange mechanism 16 may include a condenser, which transfers the heat of the refrigerant to the surrounding environment through heat exchange, so that the refrigerant is transformed from a high-pressure hot vapor state to a high-pressure liquid state (conversely, the heat exchange mechanism 16 can be an evaporator, which transfers the cold of the refrigerant to the surrounding environment through heat exchange). Of course, a radiator can also be used to further dissipate heat, especially when additional heat dissipation capacity is required. I will not elaborate on this here. It can be achieved by using existing technologies, and it can be specifically set according to actual needs.

[0049] Furthermore, on the basis of Example 2, the water pipe 10 includes a main pipe 17 and a plurality of branch pipes 18, each branch pipe 18 includes an inlet pipe 19 and an outlet pipe 20, one end of the inlet pipe 19 is connected to the main pipe 17, and the other end is connected to one side of the water coil 9, one end of the outlet pipe 20 is connected to the main pipe 17, and the other end is connected to the other side of the water coil 9; the liquid in each water coil 9 can form a closed reflux with the branch pipe 18 and the main pipe 17 connected thereto. Specifically, the main pipe 17 is the main channel of the entire water circulation system, which is responsible for transporting water to each branch pipe 18 and recovering water from the branch pipe 18. The branch pipe 18 branches out from the main pipe 17 and is connected to each water coil 9, which is used to transport water to the water coil 9 for heat exchange. Each branch pipe 18 includes an inlet pipe 19 and an outlet pipe 20 to ensure the unidirectional flow of water. One end of the inlet pipe 19 is connected to the main pipe 17, and the other end is connected to one side of the water coil 9, which is responsible for transporting water from the main pipe 17 to the water coil 9. One end of the outlet pipe 20 is connected to the main pipe 17, and the other end is connected to the other side of the water coil 9, which is responsible for transporting water from the water coil 9 back to the main pipe 17. The water coil 9 is a part of the heat exchanger, which is installed in the module box 4 and is used to exchange heat with air treated by air conditioning. The water in the water coil 9 adjusts the temperature of the air through heat exchange with the air. Each branch pipe 18 forms a closed loop with the water coil 9 and the main pipe 17 to ensure that water circulates in the system, which can ensure the continuous flow of water and the efficiency of heat exchange. Of course, a water pump, a temperature sensor and a control system can be set in the whole system to monitor and adjust the flow and temperature of water. The control system can adjust the operation of the water pump as needed to ensure the efficiency of water circulation and heat exchange. The closed-loop water circulation system can improve the energy efficiency of the system, reduce energy waste, and achieve accurate regulation of air temperature by accurately controlling the flow and temperature of water.

[0050] As a preferred embodiment of the utility model, each outlet pipe 20 is provided with a third control valve 21, and the third control valve 21 can control the water flow rate returning from the water coil 9 to the main pipe 17. Specifically, the third control valve 21 can adjust the water flow rate according to the heat exchange requirements of the water coil 9 to adapt to different cold and hot loads. The third control valve 21 can be managed by a centralized control system, which will automatically adjust the valve opening according to the feedback of the temperature sensor and the user's settings. The water flow rate can be accurately controlled to avoid overheating or cooling, thereby improving the energy efficiency of the system. More preferably, a fourth control valve 22 is provided at the inlet end of the main pipe 17, and a fifth control valve 23 is provided at the outlet end of the main pipe 17. The fourth control valve 22 controls the water flow rate of the main pipe 17 after absorbing waste heat or waste cold, and adjusts the water flow rate and pressure of the entire system. The fifth control valve 23 controls the water flow rate flowing out of the main pipe 17, and can be used to adjust the return water pressure and flow rate of the system. The fourth and fifth control valves 23 can be coordinated by the same control system to automatically adjust the valve opening according to the system demand and feedback. These control valves provide system flexibility and allow rapid response to changes in system load, such as weather changes or changes in user demand. Of course, a water supply system 24 can be connected to the main pipe 17, and the water supply system 24 can provide water or supplement water for the main pipe 17.

[0051] It should be noted that, in order to ensure that the variable temperature and humidity control element 3 has sufficient heat to regulate the cooling air, the utility model embodiment provides an embodiment 3. The difference between the embodiment 3 and the embodiments 1 and 2 is that an electric heater 27 is arranged in the module box 4. The electric heater 27 can be connected to the wire 26, and the power supply is connected through the wire 26, so as to realize the heat source supplement of the electric heating type. Figure 5 and Figure 6 As shown, this structure can be used alone or in combination with Example 1 and Example 2. When used in combination with Example 1 and Example 2, the electric heater 27 serves as a backup heat source for the variable temperature and humidity control element 3, providing a larger adjustment range for the entire system and improving the flexibility of the entire system.

[0052] For example, Figure 3 The figure shows a variable temperature and humidity control component 3 of a fluorine coil 5 type, a refrigerant interface 6 is connected to a refrigerant pipe 7, and the refrigerant pipe 7 is connected to the fluorine coil 5. The fluorine coil 5 is wrapped by a module box 4 and connected to the air supply pipe 2 or the fresh air pipe through an interface flange 8. The airflow in the air pipe is sent out after the temperature and humidity are adjusted by the variable temperature and humidity control component 3. Figure 4 The figure shows a variable temperature and humidity control component 3 of a water coil 9 type, the water inlet interface is connected to the inlet pipe 19, the water outlet interface is connected to the outlet pipe 20, the inlet and outlet water flow into the water coil 9, the water coil 9 is wrapped by the module box 4, and is connected to the air supply pipe 2 or the fresh air pipe through the interface flange 8. The airflow in the air pipe is sent out after the temperature and humidity are adjusted by the variable temperature and humidity control component 3.

[0053] like Figure 1 As shown, when the direct expansion air-conditioning unit is in cooling mode, the air is sent to each room through the air supply pipe 2 after being cooled, and then sent into the room through the air supply port 25. A part of the condensation waste heat generated by the direct expansion air-conditioning unit in cooling mode is dissipated through the refrigerant pipe 7 and the refrigerant branch pipe 13 to the variable temperature and humidity control component 3 (fluorine coil type 5) in each room, and a part of it is dissipated through the refrigerant pipe 7 to the direct expansion outdoor unit. The heat dissipated through the variable temperature and humidity control component 3 (fluorine coil type 5) is adjusted according to the room temperature and humidity requirements by controlling the refrigerant flow rate through the first control valve 14.

[0054] like Figure 2 As shown, when the four-pipe air conditioning unit is in cooling mode, the air is cooled by the cold water supply pipe 10 and the cold water return pipe 10, and then the air is temperature-adjusted by the hot water supply pipe 10 and the hot water return pipe 10, and then the air is sent to each room through the air supply pipe 2. Due to the different temperature requirements of each room, the air is temperature-adjusted and humidity-adjusted by the variable temperature and humidity control components 3 (water coil 9 type) installed on the branch pipe 12 of each room, and then sent into the room through the air supply port 25. The flow balance of the branch pipe 12 section of the variable temperature and humidity control component 3 (water coil 9 type) is preliminarily adjusted by the fourth regulating valve, and the dynamic flow balance of the water system is adjusted in real time by the fifth regulating valve. The flow through each variable temperature and humidity control component 3 (water coil 9 type) is adjusted by the electric regulating valve (third control valve 21) according to the room temperature and humidity requirements. It should be noted that the module box 4 can be made of color-coated steel plates, galvanized steel plates, aluminum alloys, zinc-aluminum plates, stainless steel plates, fiberglass, plastics and other materials according to the requirements of the use site. The variable temperature and humidity control component 3 can be equipped with a temperature control panel. The temperature control panel has an RS485 networking interface (MODBUS and other standard protocols) and can be connected to the building control system to achieve local or remote centralized management.

[0055] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model. It should be noted that the structures or components illustrated in the drawings are not necessarily drawn to scale, and the utility model omits the description of known components and processing technologies and processes to avoid unnecessary limitations on the utility model.
