a) The volume of the test product (WD × H) shall not exceed (20 ~ 35)% of the effective working space of the test box (20% recommended). It is recommended to use no more than 10% for products that generate heat during the test.
b) The ratio of the windward area of ​​the test product to the total area of ​​the test chamber on the section is not more than (35 to 50)% (35% is recommended).
c) The distance between the outer surface of the test product and the wall of the test chamber shall be at least 100~150mm (150mm is recommended).
The above three points are actually interdependent and unified. Taking a 1 cubic meter cube box as an example, the area ratio is 1: (0.35 to 0.5), which corresponds to a volume ratio of 1: (0.207 to 0.354). The ratio of the volume to the volume of 100 to 150 mm from the wall of the tank is 1: (0.343 to 0.512).
In summary, the above three points stipulate that the working chamber volume of the climatic environment test chamber should be at least 3 to 5 times the outer volume of the tested product. The reasons for this regulation are as follows: 1) The test piece is placed in the box and squeezes the smooth passage. The narrowing of the passage will result in an increase in the flow rate of the air flow. Accelerate the heat exchange between the gas stream and the test piece. This is inconsistent with the reproduction of environmental conditions, because in the relevant standards, the temperature flow around the test specimens in the test chamber should not exceed 1.7 m/s, so as to prevent the test specimens and the surrounding atmosphere from being produced. Heat transfer. When the average wind speed in the test chamber is vacant at 0.6-0.8 m/s and does not exceed 1 m/s, the wind speed of the flow field may increase when the space and area ratio specified by the two requirements of a) and b) are met. ～100)%, the average zui high wind speed is (1 to 1.7) m/s. Meet the requirements of the standard. If the volume of the test piece or the wind-breaking area is increased without restriction in the test, the airflow velocity will increase to exceed the high wind speed specified in the test standard during the actual test, and the validity of the test results will be suspected.
2) The environmental parameters of the climate chamber working chamber (such as temperature, humidity, salt spray sedimentation rate, etc.) are the results of the test under no-load conditions. Once the test piece is placed, the working environment of the test chamber is The uniformity of the parameters will have an effect, and the greater the space occupied by the test piece, the more serious this effect will be. The measured test data shows that the temperature difference between the windward and leeward sides in the flow field can reach 3-8 °C, and in severe cases it can be as large as 10 °C. Therefore, the two requirements a) and b) must be met as much as possible to ensure the uniformity of the environmental parameters around the product under test.
3) According to the principle of heat conduction, the temperature of the airflow near the tank wall is usually 2 to 3 °C from the center temperature of the flow field, and may reach 5 °C at the upper and lower limits of the high and low temperature. The temperature of the tank wall is different from the temperature of the flow field near the tank wall by 2~3 °C (depending on the structure and material of the tank wall). The greater the difference between the test temperature and the external atmospheric environment, the greater the above temperature difference, therefore, the distance from the tank wall The space within the distance (100 to 150 mm) is an unusable space.

The choice of constant temperature and humidity chamber volume has those requirements
The constant temperature and humidity chamber is suitable for the adaptability test of electric and electronic appliances, household appliances, automobiles, instrumentation, electronic chemicals, parts, raw materials and coatings, and coatings in temperature and humidity. Imported digital display instrument temperature control, humidity control, temperature and humidity visual display. The constant temperature and humidity chamber puts the tested product (components, components, components or complete machine) into the climatic environment box for testing, in order to ensure that the atmosphere around the tested product can meet the environmental test conditions specified in the test specification, the working size of the climate chamber The following points should be observed between the dimensions of the product to be tested:
