[0002] At present, the condensation test of windows generally needs to be carried out at professional large-scale test stations, which involves many problems such as transportation. It is very inconvenient to complete a condensation test. In the process of window research and development, condensation test is an indispensable test link. Research and development itself is a process of discovering deficiencies and gradually improving, so it is necessary to control the condensation situation in real time. At present, the test can only be completed in large-scale test stations. Data acquisition is not timely, and information timeliness is not enough, which affects the quality and progress of product research and development. The detection equipment of large-scale test stations has a complex structure, large volume, and very high cost. For door and window production units, it will only be frequently used during product development and idle at other times, so it is very wasteful and not suitable for separate purchase. Therefore, some people have developed some small condensation test boxes for enterprises to purchase and use, but these existing small condensation test boxes can only test single windows, and cannot fully reflect the condensation situation of the entire window.

The bracket includes four support frames 14, the two outer support frames 14 are integrally structured with the lower end of the vertical frame 5, and the two inner support frames 14 are retracted and fixed on the lower horizontal frame 4, and the retracted width can accommodate at least one inverted U-shaped support frame 18. A circle of reinforcing ribs 15 is fixed between the four support frames 14. Preferably, a layer of decorative plate 9 is fixed on the outside of the upper insulation board, a layer of decorative plate 9 is fixed on the outside of the left and right insulation boards and the two support frames 14, and a layer of decorative plate 9 is also fixed on the outside of the two support frames 14 at the lower end of the observation glass 6. An evaporator 21 and a temperature sensor 22 extending to the middle of the box body are installed on the upper insulation board in the cold box 1. The evaporator 21 is connected to the refrigeration unit 7 (preferably a refrigeration lock unit) through a pipeline. A temperature control meter 23 is installed on the decorative plate 9 at the lower end of the cold box 1. A heater 24 is installed at the upper and lower ends of the left and right insulation plates in the hot box 3, and a humidifier 25 is installed at one end of the lower insulation plate, a dehumidifier 26 is installed at the other end, and a temperature and humidity sensor 28 is installed on the upper insulation plate, which extends to the middle of the box; a temperature and humidity control meter 29 is installed on the decorative plate 9 at the lower end of the hot box 3. The signal output end of the temperature and humidity sensor 28 is connected to the signal input end of the temperature and humidity control table 29, and the signal output end of the temperature and humidity control table 29 is connected to the signal input ends of the heater 24, the humidifier 25 and the dehumidifier 26; the temperature and humidity sensor 28 outputs the signal to the temperature and humidity control table 29, and the temperature and humidity control table 29 controls the operation of the heater 24, the humidifier 25 and the dehumidifier 26 after processing; the lower ends of the four support frames 14 are hinged with universal wheels 8 with locking and height adjustment mechanisms.

[0022] The window placement frame 2 comprises a rectangular placement frame composed of two vertical frames 17 and two horizontal frames 16, which is exactly the same size as the front or rear of the rectangular frame 13 of the cold box 1 or the hot box 3, and two inverted U-shaped support frames 18 fixed at the left and right ends of the lower ends of the two vertical frames 17. The lower ends of the two inverted U-shaped support frames 18 are hinged with universal wheels 8 with locking and height adjustment mechanisms.

[0023] During the inspection, the inspected window 20 is sealed and placed in the window placement frame 2. Preferably, the inspected window 20 and the window placement frame 2 are sealed with foam glue. Then, the cold box 1 and the hot box 3 are respectively attached to the two sides of the window placement frame 2, and the inverted U-shaped support frame 18 of the window placement frame 2 is respectively inserted into the indentation of the cold box 1 and the hot box 3.

[0026] Start the test: Use the refrigeration unit 7 to lower the temperature of the cold box to 0℃-20℃ to simulate the outdoor environment in severe cold areas and cold areas in winter. Start the heater 24 and humidifier 25 in the north to increase the temperature of the hot box 3 to 18℃ and the humidity to 50% to simulate the indoor environment suitable for human habitation in the area. Set the temperature hysteresis 1 and humidity hysteresis 5% on the temperature and humidity control table 29. When the temperature and humidity sensed by the temperature and humidity sensor 28 exceed the hysteresis range, the temperature and humidity control table 29 will take effect, controlling the heater 24, humidifier 25 and dehumidifier 26 to coordinate and adjust the temperature and humidity of the hot box to keep it roughly constant temperature and humidity. The temperature control in the cold box 1 is completed by the temperature control table 23, temperature sensor 22, evaporator 21 and refrigeration unit 7 in the cold box 1.

[0027] Conduct observations: After maintaining the above state for a certain period of time, observe the condensation situation of the tested window 20 indoors and analyze the condensation nodes.
