As a large-scale environmental simulation device, the walk-in high-low temperature test room, with its spacious interior and multifunctional composite environmental simulation capabilities, has become a core platform for batch verification of the weather
In the high-low temperature test chamber, refrigerant leakage is one of the key issues affecting the stable operation of the equipment during low-temperature testing.
When placing or removing samples, the opening time of the chamber door should be minimized, and frequent opening and closing of the door should be avoided to reduce the entry of humid air from the outside.
The core prerequisite for this process is that the high-temperature aging test equipment must possess excellent temperature uniformity—that is, temperature deviations at various points within the working chamber must be controlled within an extremely smal
The control system is calibrated annually by professional engineers to ensure that the PID parameters match the actual operating conditions of the equipment.
Traditional PID control algorithms are prone to overshoot or oscillation in scenarios with rapid temperature changes, affecting recovery time.
