refrigeration systemEquipment implementation -196 ℃ ultra-low temperature dependenceCascade refrigeration cycleBy working together with different environmentally friendly refrigerants (such as R23 and R404A) through two-stage compressors, the first stage system cools the second stage refrigerant, and the evaporator absorbs the heat inside the box to achieve deep cooling. The fluorine free refrigerant scheme used in the high and low temperature test chamber reduces greenhouse effect by more than 60% compared to traditional refrigerants.
Temperature control centerThe AI adaptive PID control system is the precision core, which collects temperature signals in real time through platinum resistance (Pt100) sensors, and dynamically adjusts the cooling/heating power by combining proportional (P), integral (I), and derivative (D) algorithms to avoid temperature overshoot and oscillation. This is also the technical basis for its ± 0.2 ℃ fluctuation accuracy.
Uniformity guarantee of temperature fieldEquipped with a built-in centrifugal fan and optimized air duct design (such as upward and downward circulation), forced airflow circulation, and aerospace grade insulation materials, the temperature difference inside the box is controlled within ± 1.2 ℃, far exceeding the ± 2 ℃ level of conventional equipment.
