ApplyJOEO thermal test chamber is composed of high temperature test area (preheating area), low temperature test area (pre-cooling) and test area (RT). The transmission of hot and cold air test area by independent air channel switching should ensure that the high and low temperature are rapid, and the test sample should not be moved during the test. The JOEO thermal test chamber is suitable for the inspection of complete sets of products, PCBS, components, parts and materials for rapid temperature changes. Thermal cycling ovens are used to evaluate the thermal expansion and contraction of test samples due to chemical or sical damage and changes in the material industry in the shortest possible time. If you need more information about the models of our testing equipment, please refer to our chamber-testing (.) comControl system of thermal shock test chamber:The main controller adopts Korean high precision LCD touch key temperature controller. The controller adopts LCD display touch screen, which can display setting parameters, test curve, running time, heater working state, PID parameter self-tuning function. The control program adopts the man-machine dialogue mode, and the automatic operation function of the refrigerator can be realized only by setting the temperature. The control system has a perfect detection device to automatically display detailed faults. Alarm, configure 485 communication interface and run software. Setting accuracy: Temperature: 0.1℃ Time: Is user program capacity: 10×99 segments. Operation mode: program operation, constant operation. Individual overtemperature protection instrument. Device working time accumulator timer. The conversion time between low temperature zone and high temperature zone is less than or equal to 15 seconds. The temperature recovery time is less than or equal to 5 minutes.Introduction to the refrigeration system of the thermal shock test chamber:Refrigeration system and compressor: In order to ensure the cooling rate of the test chamber and the minimum temperature requirements, a set of imported French fully enclosed compressor composed of binary cascade air cooling refrigeration system. The cascade cooling system consists of a high temperature refrigeration cycle and a low temperature refrigeration cycle, and the connected container is an evaporative condenser, which also plays the role of energy transfer, transferring the heat energy in the working room through the two-stage refrigeration system to achieve the purpose of long temperature. The application of energy regulation technology in the design of the refrigeration system can not only ensure the normal operation of the refrigeration unit, but also effectively adjust 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.
