When the air valve module 2 is opened, the rotary dehumidification module is closed, and the airflow flows through the air valve module 2. When the air valve module 2 is closed, the airflow flows through the rotary dehumidification module 3; the rotary dehumidification module 3 is used to dehumidify the airflow.

[0026] In some embodiments, the environmental temperature and humidity control system of the present application further includes a return air mixing module 5. The return air mixing module 5 is provided with a return air mixing chamber 501, and the return air mixing chamber 501 is connected to the controlled environment through a return air duct 502; the exhaust gas in the controlled environment is partially discharged, and part is sent to the return air mixing chamber 501 through the return air duct 502 to mix the fresh air and the return air. Furthermore, the heat exchanger unit module 1 includes a first heat exchanger 101, a second heat exchanger 102 and a third heat exchanger 103. The first heat exchanger 101, the second heat exchanger 102 and the third heat exchanger 103 are arranged in series in sequence, the air valve module 2 and the rotary dehumidification module 3 are arranged between the first heat exchanger 101 and the second heat exchanger 102, and the return air mixing chamber 501 is arranged at the rear end of the air valve module 2 and the rotary dehumidification module 3.

[0027] Furthermore, the ambient temperature and humidity control system of the present application also includes a detection and feedback module and a data processing module. The detection and feedback module includes an internal sensor group and an external sensor group. The internal sensor group includes a first temperature sensor 601, a second temperature sensor 602, and a third temperature sensor 603. The first temperature sensor 601 is located at the front end of the first heat exchanger 101. The first temperature sensor 601 is used to detect the temperature of the airflow entering the first heat exchanger 101. The detected temperature is fed back to the data processing module, and the data processing module changes the operating power of the first heat exchanger according to the temperature of the external airflow; the second temperature sensor 602 is located at the rear end of the first heat exchanger 101 and is used to detect the temperature of the airflow after passing through the first heat exchanger 101; the third temperature sensor 603 is located at the rear end of the second heat exchanger 102 and is used to detect the temperature of the airflow after passing through the second heat exchanger 102.

Each module in the system, including the heat exchanger module 1, the air valve module 2, and the rotary dehumidification module 3, can be adjusted through the data detected and fed back by the detection feedback module to achieve temperature and humidity adjustment within a certain range.

[0028] Furthermore, the data processing module is used to receive and process signals fed back by the detection and feedback module. The data processing module is signal-connected to the heat exchanger module 1, the damper module 2, the rotary dehumidification module 3, and the fan module 4. After processing the data, the data processing module changes the operating states of other modules based on the data, thereby adjusting the temperature and humidity of the controlled environment.

[0029] In some embodiments, the first heat exchanger 101, the second heat exchanger 102, and the third heat exchanger 103 are each provided with a return pipe, each equipped with an electric regulating valve 1a. The electric regulating valve 1a is electrically connected to the data processing module. After receiving data from the detection and feedback module, the data processing module issues a regulating signal to the electric regulating valve 1a based on the data, adjusting the flow rate in the return pipe and thereby changing the operating state of the heat exchanger module 1.

[0030] Furthermore, the ambient temperature and humidity control system of the present application also includes a humidification module 7, which is disposed between the heat exchanger module 1 and the fan module 4.

The dehumidification side is connected in parallel with the damper module 2 and then in series with the heat exchanger module 1. When the rotary dehumidification module 3 is in operation, the regeneration fan 301 is turned on, sending the regeneration airflow to the regeneration heater 302. After being heated by the regeneration heater 302, it is blown into the regeneration side of the dehumidification rotor 303. Simultaneously, the airflow from the ambient temperature and humidity control system passes through the dehumidification side, where the dehumidification material absorbs moisture from the airflow. After the dehumidification material absorbs moisture, the dehumidification rotor 303 rotates, sending the dehumidified material to the regeneration side, where it is dried by the heated regeneration airflow.

[0032] When the ambient temperature and humidity control system of the embodiment of the present application is working, the air flow first enters the first heat exchanger 101, is heated or cooled and dehumidified by the first heat exchanger 101, and is further dehumidified by passing through the air valve module 2 or the rotary dehumidification module 3, and then enters the return air mixing chamber 501 to mix with the return air, and then passes through the second heat exchanger 102 and the third heat exchanger 103, and then passes through the humidification module 7 and is sent to the controlled environment by the fan module 4.

[0033] See also Figure 2 , the embodiment of the present application also provides an ambient temperature adjustment method, which specifically includes the following steps:

[0034] S1: Select the first air treatment mode or the second air treatment mode according to the temperature and humidity requirements of the season or the controlled environment.

[0035] S2A: If it is the first air treatment mode, the fresh air flow is heated and humidified, and then sent to the controlled environment.

[0036] S2B: If it is the second air treatment mode, the humidity content of the system air supply outlet and the humidity content at the rear end of the second heat exchanger are compared and tested. If the humidity content at the system air supply outlet is higher, the first humidity air treatment mode is selected; if the humidity content at the rear end of the second heat exchanger is higher, the second humidity air treatment mode is selected.

Furthermore, when the ambient temperature and humidity are low, the first air treatment mode is selected, and when the ambient temperature and humidity are high, the second air treatment mode is selected.

[0043] S2B1: Determine the controlled environment temperature Tset and relative humidity Rhset; calculate the moisture content dset of the air in the controlled environment based on the controlled environment temperature Tset and relative humidity RHset; calculate the moisture content doset of the air outlet of the ambient temperature and humidity control system based on the designed wet load D in the controlled environment and the air supply volume Gs of the fan module 4; doset = dset-D / Gs.

[0044] S2B2: The fresh air W is passed through the fully opened first heat exchanger 101 and the second heat exchanger 102, and the temperature T2 at the rear end of the second heat exchanger 102 is detected.

[0045] S2B3: Set the relative humidity R2 at the rear end of the second heat exchanger to 95%, calculate the outlet moisture content d2 at the rear end of the second heat exchanger based on T2 and R2, and compare d2 with doset; if d2≤doset, select the first humidity air treatment mode; if d2>doset, select the second humidity air treatment mode.

[0046] Generally, when d2≤doset, the humidity in the air is high; when d2>doset, the humidity in the air is low.

[0047] See also Figure 4 Furthermore, step S3C specifically includes: allowing the fresh air W to pass through the first heat exchanger 101 to cool and dehumidify into airflow W1, airflow W1 passes through the air valve module and flows into the return air mixing chamber 501 to mix with the return air N to form airflow C, airflow C passes through the second heat exchanger 102 to cool and dehumidify into airflow L, airflow L passes through the third heat exchanger 103 to heat and return to form airflow L1, and airflow L1 is sent to the controlled environment by the fan module 4.

[0048] Furthermore, step S3C of the ambient temperature regulation method of the embodiment of the present application also includes: detecting the temperature T1 at the rear end of the first heat exchanger 101, setting the first system target temperature T1set, and using T1 and T1set to adjust the cooling amount of the first heat exchanger 101 through the proportional integral method; detecting the humidity R0 in the controlled environment, setting the first target humidity Rhset0, and using R0 and Rhset0 to adjust the cooling and dehumidification amount of the second heat exchanger 102 through the proportional integral method; detecting the temperature T0 in the controlled environment, setting the first environmental target temperature T0set, and using T0 and T0set to adjust the heating amount of the third heat exchanger 103 through the proportional integral method.

[0049] See also Figure 5Furthermore, step S3D specifically includes: allowing the fresh air W to pass through the first heat exchanger 101 to cool and dehumidify into airflow W1, after the airflow W1 passes through the rotary dehumidification module 3 to dehumidify into airflow W2, it flows into the return air mixing chamber 501 and mixes with the return air N to form airflow C, the airflow C passes through the second heat exchanger 102 to cool and dehumidify into airflow L, and the airflow L is sent to the controlled environment by the fan module 4.

[0050] Furthermore, step S3D of the ambient temperature regulation method of the embodiment of the present application also includes: detecting the temperature T1 at the rear end of the first heat exchanger 101, setting the first system target temperature T1set, and using T1 and T1set to adjust the cooling amount of the first heat exchanger 101 through the proportional integral method; detecting the temperature T0 in the controlled environment, setting the first ambient target temperature T0set, and using T0 and T0set to adjust the cooling amount of the second heat exchanger 102 through the proportional integral method; detecting the humidity R0 in the controlled environment, setting the first target humidity Rhset0, and using R0 and Rhset0 to adjust the heating amount of the regeneration heater 302 of the rotary dehumidification module 3 through the proportional integral method.

[0051] The environmental temperature and humidity control system and environmental temperature control method of the embodiments of the present application can select different air treatment modes according to different environmental conditions and temperature and humidity requirements, thereby achieving energy-saving effects. When the air humidity in the controlled environment is high, double cooling dehumidification is used to dehumidify the air; due to the high air humidity, the temperature of the air is reduced significantly during the cooling and dehumidification process, so the third heat exchanger 103 is used to reheat the air. When the air humidity in the controlled environment is low, a combination of double cooling dehumidification and rotary dehumidification is used to dehumidify the air; at this time, the cooling dehumidification only cools the air to the set target temperature value, and the rotary dehumidification is used to control the dehumidification amount of the air; at this time, there is no need to reheat the air, which can reduce energy consumption.

[0052] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous modifications and improvements without departing from the concept of the present invention, and the present invention is intended to encompass such modifications and variations.
