Overview
The NBC-80B Thermal Shock Test Chamber is mainly used to test the resistance of materials to extremely high temperature or extremely low temperature, simulating the situation of discontinuous high temperature or low temperature environment. The device can complete the test in the shortest time, and detect the chemical changes or physical damage caused by thermal expansion and contraction of materials through thermal shock. The PID system is used to realize full digital automatic control, which is easy to operate and ensures reliable test results. The products are divided into two-box and three-box, which are suitable for metal, plastic, rubber, electronics and other industries.

8. Dual-Box test function, in line with test specifications
9, the use of new PWM cold control technology implementation of low temperature energy-saving operation, in low temperature conditions can reduce 40% energy consumption
Principle
The Thermal Shock Test Chamber uses a cascade refrigeration system, including high-temperature and low-temperature refrigeration cycles. Energy is transferred through evaporative condenser, and the thermal energy in the studio is transferred through a two-stage refrigeration system to achieve cooling. The refrigeration Working Principle is based on an inverse carrot cycle, which consists of two isothermal processes and two adiabatic processes: the refrigerant is adiabatic and compressed by the Compressor, and then the temperature rises, and then the heat is transferred to the surrounding medium through the isothermal heat exchange of the condenser, and then the adiabatic expansion of the expansion valve cools down. Finally, the temperature of the object being chilled down is reduced by the isothermal absorption of the evaporator. This cycle is repeated to achieve the purpose
