[0019] See Figures 1-2A constant temperature and humidity test chamber with a turbulence fan includes a housing 1 and an electrical control cabinet 6. The housing 1 has a sealed door 2. The electrical control cabinet 6 is located on the side of the housing 1 and has an operating panel 7 electrically connected to it. Inside the housing 1 is a test area 28 containing multiple test benches 24. Temperature and humidity probes 25, electrically connected to the electrical control cabinet 6, are installed at the bottom of each test bench 24. Ultrasonic humidifiers 23, electrically connected to the electrical control cabinet 6, are installed on both side walls of the test area 28. A rotary dehumidifier 26 and a refrigeration dehumidifier 27, electrically connected to the electrical control cabinet 6, are located at the bottom of the test area 28. An air supply ceiling 22 is installed at the top of the test area 28. A turbulence fan 16 is installed at the bottom of the plate 22 via the ceiling fastener 10. The top of the air supply ceiling 22 is connected to the buffer chamber 21. The buffer chamber 21 is connected to the constant temperature and humidity air conditioner 15 via the air duct 20. The constant temperature and humidity air conditioner 15 is connected to the fresh air handling unit 13 via the secondary electric heater 14. The fresh air handling unit 13 is connected to the fresh air pretreatment unit 11 via the primary electric heater 12. The fresh air pretreatment unit 11 is connected to the outside air via the fresh air inlet 8. An anti-backflow air vent 19 is provided near the bottom of the test area 28. The anti-backflow air vent 19 is connected to the exhaust hood 18 located on the side of the box 1 via the exhaust fan 17.

[0020] See Figure 1 The chamber 1 and the sealed door 2 are connected by a sealing hinge 5 on one side. A safety lock 4 is installed on the other side of the sealed door 2. An observation window 3 is installed on the sealed door 2 and is fixedly and sealed to the sealed door 2. This setting helps to ensure the airtightness of the test area 28 and avoids external air interference with the internal temperature and humidity. It ensures that the humidity and temperature inside the test area 28 are controllable and stable. The staff can observe the internal test process through the observation window 3.

[0021] See Figure 2 An advanced filter 9 is installed between the fresh air inlet 8 and the primary electric heater 12. The advanced filter 9 is detachably fixed to the housing 1 by bolts. This arrangement facilitates the use of the advanced filter 9 to filter the incoming fresh air and prevent dust and large particulate impurities in the fresh air from clogging the internal pipes.

[0022] See Figure 2 The ceiling fastener 10 and the air supply ceiling 22 are detachably fixed together by bolts. This arrangement makes it convenient to remove the air supply ceiling 22 in the required area for inspection and maintenance when the ceiling fastener 10, the turbulence fan 16 and the air supply ceiling 22 need to be inspected and maintained.

[0023] See Figure 3The ceiling fastener 10 includes a mounting base 1001 for installing the turbulence fan 16. The mounting base 1001 is fixedly installed on the air supply ceiling 22 by fixing bolts 1002. The mounting base 1001 has four mounting slots 1003 around its perimeter. This arrangement allows the ceiling fastener 10 to be fixed by the fixing bolts 1002. At the same time, the mounting slots 1003 can be used to install individual panels of the air supply ceiling 23.

[0024] See Figure 2 The constant temperature and humidity air conditioner 15, the fresh air handling unit 13, the primary electric heater 12, and the secondary electric heater 14 are all electrically connected to the electrical control cabinet 6. This arrangement facilitates real-time monitoring, feedback, and adjustment of the working process of the constant temperature and humidity air conditioner 15, the fresh air handling unit 13, the primary electric heater 12, and the secondary electric heater 14 using the electrical control cabinet 6, thereby controlling the temperature and humidity in the test chamber and improving the accuracy of temperature and humidity control in the test chamber.

[0025] Working Principle: When using this device, place the test equipment and apparatus on the test bench 24, then close the sealing door 2. Personnel can conduct tests inside the chamber 1. Under the negative pressure of the fresh air pretreatment unit 11, external air is drawn in through the fresh air inlet 8 and pretreated by the fresh air pretreatment unit 11. The pretreated hot air is further heated by the primary electric heater 12 and then sent to the fresh air handling unit 13 for secondary treatment. After secondary treatment, the fresh air is reheated by the secondary electric heater 14 and sent to the constant temperature and humidity air conditioner 15 for temperature and humidity control. Then, the fresh air with suitable temperature and humidity is sent to the buffer chamber 21 through the air duct 20, and finally delivered to the test area 28 through the air supply ceiling 22. During this process, the turbulence fan 16 can provide mixing... This improves the uniformity of airflow, resulting in better temperature and humidity balance within the test chamber and providing a constant temperature environment for the experiment. Simultaneously, the rotary dehumidifier 26 and the refrigeration dehumidifier 27 can work with multiple ultrasonic humidifiers 23. Under the control of the operating commands input into the control panel 7, the electrical control cabinet 6 performs unified regulation, thereby controlling the humidity within the test area 28. Temperature and humidity probes 25 monitor the temperature and humidity information within the test area 28 in real time and feed it back to the electrical control cabinet 6 for processing. Based on the feedback data and the operating commands input from the control panel 7, the electrical control cabinet 6 provides real-time feedback and adjusts the operating parameters of each electrical device, thus maintaining a suitable temperature and humidity environment within the test area 28. The temperature and humidity information within the test area 28 is also displayed on the control panel 7 for convenient viewing and adjustment by staff.
