Adopts intelligent energy-saving control method, according to the temperature demand in the box, PID controls the solenoid valve switch to output cooling capacity or PID controls the heating wire; it is equipped with an evaporating pressure regulator, which can accurately control the temperature of the evaporator and prevent the evaporator from freezing when the humidity is increased; Equipped with independent return air and exhaust temperature control circuits; a series of energy-saving and emission-reduction processes such as oxygen-free copper tube gas shielded welding.

During the application process of solar modules, they will withstand various severe weather tests. Among them, the performance of components such as the ability to withstand high temperature, high humidity, and long-term moisture penetration needs to be evaluated. DH environmental simulation test can verify and evaluate the reliability of components or materials, and through thermal fatigue induced failure mode, to make an early identification of manufacturing defects.

With the continuous power supply developed by Millennial, according to the current curve in the legend to simulate the working conditions at different temperatures during the day and night, it can perfectly present the performance of the components at each temperature, and bring good data reference for the research and quality inspection work.
