Various materials, electromechanical parts and complete machine products are influenced by various environmental stresses (such as temperature, humidity, air pressure, solar radiation, wind, rain, snow, mold, salt fog and the like) in the production, storage and use processes of the materials, the electromechanical parts and the complete machine products; the environmental test chamber (hereinafter referred to simply as test chamber) includes: the test box is necessary test equipment for carrying out various environmental stress tests, detecting and verifying the environmental adaptability of products and evaluating the quality and reliability of the products.
Generally, the temperature in the temperature and humidity test box has a wide variation range and a high variation rate, the high temperature limit is close to 200 ℃, the low temperature needs to reach about-70 ℃, and the rapid temperature change test usually requires a temperature variation rate of more than 5 ℃/min.
For a test box with a low-temperature test function, when the temperature in the test box is reduced to a certain degree, the phenomenon of condensation on the outer wall surface of the test box and the outer side surface of a door or window can occur; the general method for solving the dewing is that resistive heating wires are arranged on the outer wall of a test box, a box door and a glass observation window, and when the temperature in the test box is reduced to a certain temperature value, the resistive heating wires are electrified to heat, so that the aim of preventing dewing is fulfilled; the temperature in the box for controlling the resistance electric heating wire to be electrified is about-10 ℃ to 10 ℃, is generally factory set by a test box manufacturer, and can also be selected and set by a user; to ensure that condensation does not occur, this temperature value is usually set relatively high, even above 10 ℃.

firstly, energy conservation is not facilitated; as long as the temperature in the environment test equipment is lower than a set value, the resistive heating wire is electrified, and the resistive heating wire consumes energy with the maximum power.
Secondly, a situation of poor anti-condensation effect may occur; if the temperature value for controlling the resistance heating wire to be electrified is low, condensation possibly occurs on the outer wall surface of the environment test equipment and the outer side surface of the door and the window, but the resistance heating wire does not start to be electrified to generate heat.
Thirdly, the performance of the environmental test equipment is influenced; as long as the temperature in the environmental test equipment is lower than a set value, the resistive heating wire is electrified and works with the maximum power, which means that a heating source is artificially introduced at the periphery of the working area of the environmental test equipment, so that technical indexes such as temperature fluctuation, temperature uniformity, temperature change rate and the like of the environmental test equipment are inevitably negatively influenced to a certain degree.
