Description

Technical Field

[0001] The utility model relates to a test cabin, in particular to a large glass-enclosed test cabin. Background Art

[0002] As people pay more and more attention to air quality, the use of air purification equipment is no longer limited to small environments such as cars and bedrooms, but has extended to large spaces such as large living rooms, offices, and workshops. At this time, high-volume air purification equipment is needed. Conventional environmental test chambers on the market are often small in size and are no longer suitable for testing parameters such as purification efficiency of high-volume air purification equipment. This affects the accuracy of test results and cannot meet the testing needs of large-scale air purification equipment with high air volume or large-space simulated environments. Therefore, there is an urgent need for a large-scale environmental test chamber with a more reasonable design, superior performance, and the ability to simulate larger environments.

[0021] The following is a clear and complete description of the technical solutions in the embodiments of the present invention, in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary persons in this field without creative work are within the scope of protection of the present invention.

[0022] Embodiment: A large glass-enclosed test chamber.

[0023] Reference Figure 1 and Figure 2As shown, a large glass-enclosed test chamber comprises a chamber 1, the frame, top and bottom panels of which are laser-welded from SUS304 stainless steel. The surrounding walls are constructed of high-strength tempered glass, and the glass panels are sealed with environmentally friendly, bottom-release glass glue, resulting in excellent light transmittance, durability, and corrosion resistance. The simulated environmental space within the chamber reaches 81 cubic meters, with a smooth, corner-free interior for easy cleaning and maintenance. A sealed door 2 is installed on the front side of the chamber 1. The door frame is made of stainless steel, and the door panels are made of glass, connected with environmentally friendly glass glue. A silicone rubber sealing strip is installed on the inside of the door frame to ensure good airtightness within the chamber. A sample delivery port 3 is provided on one side of the sealing door 2, a sampling tube 5 is provided on one side of the sample delivery port 3, and operating gloves 4 are provided on one side of the sample delivery port 3 and the sampling tube 5 to facilitate the delivery and sampling of pollutants. A real-time monitoring display screen 6 is installed above the sampling tube 5. A temperature sensor, a humidity sensor, and a pressure sensor are installed in the cabin 1. The temperature sensor, humidity sensor, and pressure sensor are all electrically connected to the real-time monitoring display screen 6 installed on the front side of the cabin 1, so that parameters such as temperature, humidity, and pressure in the cabin 1 can be displayed through the real-time monitoring display screen 6. A clean air-conditioning purification box 7 is installed on the left side of the cabin 1, and the air outlet of the clean air-conditioning purification box 7 is connected to the top of the cabin 1 through the return air duct 10, and the air inlet of the clean air-conditioning purification box 7 is connected to the bottom of the left side of the cabin 1 through the outlet duct 8. A vacuum-tight valve 9 is installed on the outlet duct 8 to facilitate the control of the air volume of the clean air-conditioning purification box. A stirring fan 11 and a circulating fan 12 are installed in the cabin 1, and the air outlet of the circulating fan 12 is connected to the air inlet of the clean air-conditioning purification box 7 through a pipeline. The stirring fan 11 and the circulating fan 12 constitute the air-conditioning internal circulation purification system and air stirring system of this test cabin. After the internal circulation purification makes the air in the cabin meet the requirements, the sealing valve is closed to form a closed clean space. When injecting test standard gas or particulate smoke into the cabin, due to the large space, to ensure uniform concentration within the sealed cabin 1, dual stirring fans 11 and two diagonally arranged axial flow fans are installed. These can quickly stir the temperature, humidity, and air mixing degree within the cabin, shorten the test process time, and improve test accuracy. A pollutant generator 14 and a pollutant concentration detector 13 are installed within the cabin 1. The pollutant generator 14 is used to generate pollutants required for testing, such as cigarette smoke, formaldehyde, TVOC, etc. The device can adjust the type and concentration of pollutants as needed. The pollutant concentration detector 13 is used to monitor the concentration of pollutants within the cabin 1 in real time to ensure the accuracy of the test results. The device can simultaneously detect multiple pollutants and output corresponding data reports. An independent drain pipe is provided on the left side of the cabin 1, and a vacuum-tight valve 9 is installed on the drain pipe. After the test is completed, the air in the cabin can be discharged to the outside through the drain pipe and then re-enter the cabin.

[0024] In this embodiment, during the specific operation, the air purifier to be tested is first placed into the cabin 1 through the sealed door 2, and then the sealed door 2 is closed. Then, the temperature, humidity and air cleanliness in the cabin 1 are adjusted through the real-time monitoring display screen 6, and the mixing degree in the cabin 1 is made to meet the standard through the stirring fan 11 and the circulating fan 12 to simulate the required test environment. Then, the pollutants required for the test are generated by the pollutant generator 14, and the concentration of the pollutants in the cabin is monitored in real time by the pollutant concentration detector 13. At the same time, the various environmental parameters in the cabin are monitored in real time through the real-time monitoring display screen 6, and the data during the test process is recorded. If additional pollutants need to be tested, the sample delivery port 3 is opened on the side, and the pollutants are placed on the pollutant generator 14 and tested again. Finally, the performance of the air purifier is evaluated and optimized based on the test data and report.

[0025] This large, glass-enclosed test chamber accurately simulates real-world environments, precisely controls test conditions, and monitors test data in real time, providing reliable support for large-space simulated environmental testing. Furthermore, it can simulate large spaces: the chamber 1 is spacious, effectively simulating large spaces such as offices and large reception rooms. It also saves test time: for consecutive tests, instead of opening the sealed door 2 to place samples, simply open the sample delivery port 3 and place the sample on the pollutant generator 14, saving time and ensuring the safety of the tester. It also accurately simulates the environment: the air conditioning internal circulation purification system and air agitation system accurately simulate different operating environments, providing a realistic and reliable test environment for air purifier performance testing. Furthermore, it accurately controls test conditions: the pollutant generator 14, the air conditioning internal circulation purification system, and the air agitation system enable precise control of test conditions, ensuring the accuracy and comparability of test results. Furthermore, it enables real-time data monitoring: the pollutant concentration detector 13 and the real-time monitoring system enable real-time monitoring of test data, enabling timely detection and resolution of abnormalities, thereby improving test efficiency and accuracy. And it is easy to maintain and clean: the interior of the cabin 1 is smooth without dead corners, easy to clean and maintain, reducing maintenance costs and difficulty.
