[0021] The specific implementation methods of the present disclosure are further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present disclosure, but are not used to limit the scope of the present disclosure.

[0022] Figure 1 FIG. 1 is a schematic diagram of the functional modules of the temperature and humidity control system for clean fresh air according to an embodiment of the present disclosure. Figure 1 As shown, the temperature and humidity control system 100 includes a first dehumidification clean air unit, a second dehumidification clean air unit, a temperature and humidity judgment module, a plurality of variable air volume modules and a plurality of temperature-adjusting clean air units.

[0023] The first dehumidification clean air unit is used to generate the first dehumidification clean fresh air.

[0024] The second dehumidification clean air unit is used to generate the second dehumidification clean fresh air.

[0025] The temperature and humidity judgment module is used to confirm whether the real-time temperature of each accommodation space in the multiple accommodation spaces meets the preset temperature threshold, and whether the real-time humidity of each accommodation space meets the preset humidity threshold, and output the temperature confirmation result and humidity confirmation result of each accommodation space.

[0026] A plurality of variable air volume modules are used to adjust the ratio of the first dehumidified clean fresh air and the second dehumidified clean fresh air delivered to the corresponding accommodating space according to the humidity confirmation result, so as to output the target dehumidified clean fresh air to each accommodating space.

[0027] A plurality of temperature-adjustable clean air units are used to adjust the temperature of the target wet clean fresh air corresponding to each accommodating space according to the temperature confirmation result.

[0028] It can be understood that the number of temperature-adjusting clean air units, variable air volume modules, and accommodating spaces in the temperature and humidity control system 100 provided in the embodiment of the present disclosure is the same and is connected to each other in a one-to-one correspondence. For example, the number of temperature-adjusting clean air units and variable air volume modules is determined according to the number of accommodating spaces, and the embodiment of the present disclosure does not limit this.

[0029] For example, Figure 1 As shown, the multiple variable air volume modules can be variable air volume module 1, variable air volume module 2, ..., variable air volume module N. Correspondingly, the multiple temperature-adjusting clean air units can be temperature-adjusting clean air unit 1, temperature-adjusting clean air unit 2, ..., temperature-adjusting clean air unit N. N is an integer greater than or equal to 2.

[0030] Among them, the temperature-adjusting clean air unit 1, the temperature-adjusting clean air unit 2, ..., and the temperature-adjusting clean air unit N are respectively arranged in the accommodating space 1, the accommodating space 2, ..., and the accommodating space N.

[0031] In the disclosed embodiment, the accommodating space may be various departments of a hospital, clean wards, operating rooms, special departments, etc.

[0032] In the disclosed embodiment, the humidity of the first dehumidified clean fresh air is different from the humidity of the second dehumidified clean fresh air, and the total amount of the first dehumidified clean fresh air and the second dehumidified clean fresh air is a certain value.

[0033] For example, the total amount of the first dehumidified clean fresh air and the second dehumidified clean fresh air input to each accommodation space may be 1000m 3 It can be understood that the total amount of the first dehumidified clean fresh air and the second dehumidified clean fresh air is only for illustration and can be adjusted according to actual application requirements.

[0034] For example, to meet the dehumidification requirements of each accommodation space in different scenarios, the humidity of the second dehumidified clean fresh air is lower than that of the first dehumidified clean fresh air. The ratio of the second dehumidified clean fresh air to the first dehumidified clean fresh air in the clean air duct is adjusted through the variable air volume module, so that the target dehumidified clean fresh air finally output to the accommodation space is different, thereby achieving the purpose of dehumidifying the accommodation space.

[0035] For example, when the humidity confirmation result indicates that the humidity in a plurality of storage spaces is too low, the amount of second dehumidified clean fresh air delivered by the second dehumidified clean air unit to the storage space with too high humidity is reduced, and at the same time, the amount of first dehumidified clean fresh air output by the first dehumidified clean air unit corresponding to the storage space is increased to increase the humidity in the storage space with too low humidity.

[0036] For example, when the humidity confirmation result indicates that the humidity in multiple accommodating spaces is too high, the amount of dehumidified clean fresh air delivered by the second dehumidification clean air unit to the operating room with too high humidity is increased, and the amount of clean fresh air output by the first dehumidification clean air unit corresponding to the operating room is reduced to reduce the humidity in the operating room with too high humidity.

[0037] More specifically, the first dehumidified clean air unit outputs the first dehumidified clean fresh air that has been filtered, cooled and dehumidified and has been initially temperature-adjusted. At the same time, the second dehumidified clean air unit outputs the second dehumidified clean fresh air that has been filtered and dehumidified. Both the first dehumidified clean fresh air and the second dehumidified clean fresh air are transported to each accommodation space through the clean air duct.

[0038] In the embodiment of the present disclosure, in order to meet the actual usage requirements of the fresh air humidity of each accommodating space, the supply volume ratio of two clean fresh air with different dehumidification degrees (i.e., the first dehumidified clean fresh air and the second dehumidified clean fresh air) delivered to each accommodating space is adjusted respectively through a variable air volume module that matches each accommodating space one by one, so as to realize independent adjustment of the humidity of each accommodating space.

[0039] Since the first dehumidified clean fresh air is pre-temperatured during the dehumidification stage, in order to meet the actual usage requirements of the fresh air temperature in the accommodating space, only a small degree of temperature adjustment is required during the subsequent temperature adjustment stage through the temperature-adjusting clean air unit, which can reduce the overall energy consumption of the system and improve the temperature and humidity control accuracy.

[0040] According to the embodiments of the present disclosure, the temperature and humidity can be controlled separately to meet the individual needs of each operating room, and the lower temperature and humidity requirements of the operating room can be met. The present disclosure takes energy saving as a highlight, and can flexibly and independently adjust the temperature and humidity of the clean fresh air in each accommodation space, thus building a new purification air conditioning ecology.

[0041] As a preferred embodiment, the first dehumidified clean air unit can adopt a water-cooled surface cooler structure. For example, the first dehumidified clean air unit adopts a first-stage cooling dehumidification. When the first dehumidified clean air unit is used as an air treatment unit for dry condition temperature adjustment, according to the designed fresh air volume configuration, the first dehumidified clean air unit has a surplus of cold capacity. No matter what the designed value is, the humidity in the accommodation space may be too high in summer. Therefore, in order to meet the use requirements of different actual scenarios, a second dehumidified clean air unit needs to be configured at the same time to adjust the humidity of the clean fresh air when the indoor humidity does not meet the use requirements, so as to ensure the humidity requirements of the air in the operating room.

[0042] As a preferred embodiment, the second dehumidification clean air unit can adopt a low-temperature regenerative rotor structure. For example, the regeneration temperature of the low-temperature regenerative rotor dehumidification only needs 50℃~70℃, and the regeneration heat source can be completely replaced by the condensation heat of the medium-temperature heat pump or preheating of various heat recovery processes, which requires steam heating or electric heating, which consumes the most energy in the conventional rotor dehumidification system, and can greatly reduce the operating energy consumption of the rotor dehumidification.

[0043] In the disclosed embodiment, the low-temperature regenerative rotor structure utilizes low-temperature regenerative rotor dehumidification technology to adsorb and desorb water molecules in the second dehumidified clean fresh air output by the second dehumidified clean air unit through hydrophilic absorption particles, thereby achieving better dehumidification efficiency and energy-saving performance.

[0044] After completing the humidity adjustment, the temperature of the target wet clean fresh air is further adjusted and purified through the temperature-adjusting clean air units corresponding to each accommodating space, and finally the clean fresh air with temperature and humidity that meet the requirements is output.

[0045] For example, the temperature-adjustable clean air units corresponding to each accommodating space may be clean air conditioning units specially used in operating rooms.

[0046] In the disclosed embodiment, the system further includes: a temperature and humidity monitoring module, which is electrically connected to the temperature and humidity judgment module and is used to obtain the real-time temperature and real-time humidity of each of the multiple operating rooms.

[0047] It can be understood that the temperature and humidity monitoring module can be set in each operating room, and the temperature and humidity monitoring module includes at least a temperature sensor and a humidity sensor to detect the real-time temperature and real-time humidity of the corresponding operating room.

[0048] According to an embodiment of the present disclosure, the preset temperature threshold and the preset humidity threshold may be set according to the season. The preset temperature threshold and the preset humidity threshold may be different in different seasons.

[0049] For example, the first season mode and the second season mode are preset according to the temperature and humidity characteristics of different seasons, the first temperature threshold and the first humidity threshold are set to match the first season mode, and the second temperature threshold and the second humidity threshold are set to match the second season mode.

[0050] In the embodiment of the present disclosure, the temperature and humidity judgment module is used to confirm the corresponding season mode according to the current time, and according to the season mode, call the preset temperature threshold and preset humidity threshold corresponding to the season mode to confirm whether the temperature and humidity of each storage space in different seasons meet the actual usage requirements.

[0051] Figure 2 FIG. 1 is a schematic diagram of the structure of the temperature and humidity judgment module according to an embodiment of the present disclosure. Figure 2 As shown, the temperature and humidity judgment module 200 includes a humidity judgment submodule 210 , a temperature judgment submodule 220 and a season confirmation submodule 230 .

[0052] The humidity determination submodule 210 is used to compare the real-time humidity of each of the multiple accommodation spaces with the preset humidity threshold, and obtain a humidity confirmation result that matches each of the multiple accommodation spaces one by one. The humidity confirmation result is one of too low humidity, normal humidity, and too high humidity.

[0053] The temperature determination submodule 220 is used to compare the real-time temperature of each of the multiple accommodation spaces with the preset temperature threshold, and obtain a temperature confirmation result that matches each of the multiple accommodation spaces one by one. The temperature confirmation result is one of the temperature being too low, the temperature being normal, and the temperature being too high.

[0054] The season confirmation submodule 230 is used to confirm the working modes of the multiple temperature-adjusting clean air units according to the current time, and the working modes of the multiple temperature-adjusting clean air units include a first season mode and a second season mode.

[0055] In the embodiment of the present disclosure, the preset temperature threshold indicates a normal temperature range. The preset humidity threshold indicates a normal humidity range.

[0056] For example, in a certain implementation scenario, the preset temperature threshold may be set to 21° C. to 25° C. The preset humidity threshold may be set to 30% to 60%.

[0057] For example, the temperature confirmation result may include normal temperature, too low temperature (lower than 21° C.), or too high temperature (higher than 25° C.).

[0058] For example, the humidity confirmation result may include normal humidity, too low humidity (lower than 30%), or too high humidity (higher than 60%).

[0059] It should be noted that the preset temperature threshold, preset humidity threshold, temperature confirmation result and specific numerical values ​​in the humidity confirmation result shown in the embodiment of the present disclosure are only exemplary, and these parameters can be set according to actual needs.

[0060] In the embodiment of the present disclosure, when the season confirmation submodule confirms that the working mode of the multiple temperature-adjusting clean air units is the first season mode, the first temperature threshold is called as the preset temperature threshold, and the first humidity threshold is called as the preset humidity threshold. And, when the season confirmation submodule confirms that the working mode of the multiple temperature-adjusting clean air units is the second season mode, the second temperature threshold is called as the preset temperature threshold, and the second humidity threshold is called as the preset humidity threshold. Wherein, the first temperature threshold is lower than the second temperature threshold, and the first humidity threshold is higher than the second humidity threshold.

[0061] For example, the first season mode may be defaulted to the summer mode, and the second season mode may be defaulted to the winter mode. Due to seasonal differences in temperature and humidity, the preset temperature threshold and preset humidity threshold of the summer mode and the winter mode may be different. For example, the preset temperature threshold of the summer mode may be lower, and the humidity may not be higher than 65%, while the preset temperature threshold of the winter mode may be higher, and the humidity may not be lower than 30%.

[0062] Figure 3 Schematic diagram of application scenario of temperature and humidity control system for clean fresh air according to an embodiment of the present disclosure. Figure 3 In the illustrated embodiment, an example is given in which the number of variable air volume modules, temperature-controlled clean air fans, and accommodating spaces is 3. It can be understood that in other practical application scenarios, the number of variable air volume modules, temperature-controlled clean air fans, and accommodating spaces can be 4, 5, 6, or other numbers, and the embodiments of the present disclosure are not limited to this.

[0063] like Figure 3 As shown, the temperature and humidity control system of the clean fresh air includes a first dehumidification clean air unit 1, a second dehumidification clean air unit 2, three temperature-adjusting clean air units 3, three variable air volume modules 4, and a temperature and humidity judgment module (not shown in the figure).

[0064] The first dehumidification clean air unit 1 is used to generate the first dehumidification clean fresh air.

[0065] The second dehumidification clean air unit 2 is used to generate second dehumidification clean fresh air.

[0066] The temperature and humidity judgment module is used to confirm whether the real-time temperature of each of the three operating rooms (operating room 1, operating room 2 and operating room 3) meets the preset temperature threshold, and whether the real-time humidity of each operating room meets the preset humidity threshold, and output the temperature confirmation result and humidity confirmation result of each operating room.

[0067] The three temperature-adjusting clean air units 3 are used to adjust the temperature of the target wet clean fresh air corresponding to each operating room according to the temperature confirmation result. Among them, the three temperature-adjusting clean air units 3 are respectively arranged in operating room 1, operating room 2 and operating room 3, and are used to adjust the temperature of the target wet clean fresh air in operating room 1, operating room 2 and operating room 3.

[0068] A plurality of variable air volume modules 4 are used to adjust the ratio of the first dehumidified clean fresh air and the second dehumidified clean fresh air delivered to the corresponding operating room according to the humidity confirmation result, so as to output the target dehumidified clean fresh air to each operating room.

[0069] In the disclosed embodiment, the first dehumidification clean air unit 1 may be a clean fresh air unit dedicated to an operating room, used to deliver clean fresh air to each operating room. The clean fresh air is pre-temperature-adjusted clean fresh air.

[0070] In the disclosed embodiment, the second dehumidification clean air unit 2 can adopt a low temperature regeneration rotor structure, such as a low temperature regeneration rotor dehumidification clean fresh air unit. It can be understood that the dehumidification principle of the low temperature regeneration rotor dehumidification clean fresh air unit is as shown in the above embodiment, and for the sake of simplicity, it will not be repeated here.

[0071] It should be noted that the structures of the first dehumidification clean air unit 1 and the second dehumidification clean air unit 2 in the disclosed embodiment are interchangeable, and the clean fresh air output is also interchanged accordingly. In the above example, the humidity of the second dehumidification clean fresh air is lower than the humidity of the first dehumidification clean fresh air, and the following embodiments are used as examples. In the case where the structures of the first dehumidification clean air unit 1 and the second dehumidification clean air unit 2 are interchangeable, the humidity of the first dehumidification clean fresh air is lower than the humidity of the second dehumidification clean fresh air.

[0072] exist Figure 3 In the illustrated embodiment, the system also includes a temperature and humidity monitoring module (not shown in the figure), which is electrically connected to the temperature and humidity judgment module, and is used to obtain the real-time temperature and real-time humidity of operating room 1, the real-time temperature and real-time humidity of operating room 2, and the real-time temperature and real-time humidity of operating room 3.

[0073] It can be understood that the temperature and humidity monitoring modules can be respectively arranged in operating room 1, operating room 2 and operating room 3. Each temperature and humidity monitoring module includes at least a temperature sensor and a humidity sensor to detect the real-time temperature and real-time humidity of the corresponding operating room.

[0074] The temperature and humidity judgment module is used to confirm whether the real-time temperature of operating room 1, operating room 2 and operating room 3 meets the preset temperature threshold, and whether the real-time humidity of operating room 1, operating room 2 and operating room 3 meets the preset humidity threshold, and output the temperature confirmation result and humidity confirmation result of each operating room.

[0075] For example, the temperature and humidity judgment module is used to compare the real-time temperature of operating room 1 obtained by the temperature and humidity monitoring module with a preset temperature threshold, and to compare the real-time humidity of operating room 1 with a preset humidity threshold, to obtain a temperature confirmation result and a humidity confirmation result corresponding to operating room 1. It can be understood that the temperature and humidity comparison process of operating room 2 and operating room 3 is the same as that of operating room 1, and for the sake of simplicity, it will not be repeated here.

[0076] In the disclosed embodiment, three variable air volume modules 4 correspond one-to-one to operating room 1, operating room 2 and operating room 3, and are used to adjust the ratio of the first dehumidified clean fresh air to the second dehumidified clean fresh air delivered to each operating room, and to keep the total amount of target dehumidified clean fresh air input to each operating room at a certain value.

[0077] It is understood that the total amount of target dehumidified clean fresh air is set according to actual needs. For example, the total amount can be 1000m 3 / h.

[0078] For example, when the humidity confirmation result indicates that the humidity in the operating room 1 is too high, the variable air volume module corresponding to the operating room 1 increases the second dehumidified clean fresh air supply volume input to the operating room 1, and reduces the first dehumidified clean fresh air supply volume input to the operating room 1, so as to reduce the humidity of the clean fresh air in the operating room 1.

[0079] For example, when the humidity confirmation result indicates that the humidity in the operating room 1 is too low, the variable air volume module corresponding to the operating room 1 increases the first dehumidified clean fresh air supply volume input to the operating room 1, and reduces the second dehumidified clean fresh air supply volume input to the operating room 1, so as to increase the humidity of the clean fresh air in the operating room 1.

[0080] For example, when the humidity confirmation result indicates that the humidity of the operating room 1 is normal, the air supply volume of each dehumidified clean fresh air currently input to the operating room 1 is kept unchanged.

[0081] It can be understood that the regulation principle of the clean fresh air input into operating room 2 and operating room 3 is the same as that of operating room 1. For the sake of simplicity, it will not be repeated here.

[0082] According to the embodiment of the present disclosure, three variable air volume modules 4 matched one by one with operating room 1, operating room 2 and operating room 3 respectively adjust the air supply ratio of the first dehumidified clean fresh air and the second dehumidified clean fresh air delivered to operating room 1, operating room 2 and operating room 3, so that the humidity of the target clean fresh air of operating room 1, operating room 2 and operating room 3 can meet different actual use requirements. This process can realize independent humidity adjustment of operating room 1, operating room 2 and operating room 3 to ensure efficient and rapid dehumidification work.

[0083] In the disclosed embodiment, by providing corresponding variable air volume modules on the clean air duct branches of each operating room, the humidity in each operating room can be independently controlled to improve the user experience.

[0084] In addition, since the first dehumidified clean fresh air is pre-temperature-adjusted during the dehumidification stage, the clean fresh air temperature of each operating room can meet different actual usage requirements. The subsequent temperature adjustment stage through the three temperature-adjusting clean air units 3 only requires a small re-temperature adjustment, which can reduce the overall energy consumption of the system and improve the temperature and humidity control accuracy. Through the separate control of temperature and humidity, the personalized needs of operating room 1, operating room 2 and operating room 3 can be met, and the requirements for lower temperature and humidity in the operating room can be met. The present disclosure takes energy saving as a highlight, and can flexibly and independently adjust the temperature and humidity of the clean fresh air in each operating room, building a new purification air conditioning ecology.

[0085] According to the embodiment of the present disclosure, three temperature-adjusting clean air units 3 correspond to operating room 1, operating room 2 and operating room 3 one by one, and are respectively arranged in operating room 1, operating room 2 and operating room 3. The temperature-adjusting clean air unit is used to adjust the temperature of the target wet clean fresh air corresponding to each operating room according to the temperature confirmation result.

[0086] For example, when the temperature confirmation result indicates that the temperature of the target wet clean fresh air in the operating room 1 is too high, the temperature of the target wet clean fresh air is lowered by the temperature-adjusting clean air unit 3 in the operating room 1 so that the actual required temperature is reached in the operating room 1.

[0087] For example, when the temperature confirmation result indicates that the temperature of the target wet clean fresh air in the operating room 1 is too low, the temperature of the target wet clean fresh air is increased by the temperature-adjusting clean air unit 3 in the operating room 1 to reach the actual required temperature in the operating room 1.
