The temperature shock test chamber is a common test equipment in the fields of aviation, automobile, household appliances, scientific research, etc., used to test and determine the parameters and performance of electrical, electronic and other products and materials after the temperature environment impact changes during the temperature tests. A single air-cooled refrigeration system composed of semi-closed compressors is adopted. A low temperature refrigeration cycle, its connecting container is an evaporative condenser, which also plays the role of energy transfer. It transfers the thermal energy in the chamber through the single-stage refrigeration system to achieve the purpose of cooling. The design of the refrigeration system applies energy regulation technology. An effective treatment method can not only ensure the normal operation of the refrigeration unit, but also effectively regulate the energy consumption and cooling capacity of the refrigeration system, so that the operating cost and failure rate of the refrigeration system can be reduced to a more economical state.
Function of temperature shock test chamber:
1. The temperature change of the temperature shock test chamber is to complete the transition of temperature shock within five minutes. Moreover, the temperature shock is completed under the condition of nonlinearity.
2. The temperature change is to complete the cooling and heating within the specified time, which is non-linear and linear. For example, for a device with a temperature range of - 40 ℃ to 80 ℃, it takes 24 minutes from 80 ℃ to - 40 ℃ under linear cooling, which is much faster than the general high and low temperature testing machine, because the standard high and low temperature test chamber is non-linear at 1 ℃ /min. Of course, the equipment at 10 ℃, 20 ℃ and 30 ℃ per minute can also complete heating and cooling in a very short time. The purpose of the test is to quickly raise and lower the temperature, so it is also called a fast temperature rise and lower test chamber.
