Cooling System | ||
| After the liquid refrigerant absorbs the heat of the cooled object in the evaporator, it is vaporized into low-temperature and low-pressure steam, sucked by the compressor, compressed into high-pressure high-temperature steam, discharged into the condenser, and radiated to the cooling medium in the condenser, condensed into a high-pressure liquid, throttling through a throttle valve into a low-pressure low-temperature refrigerant, and again entering the evaporator to absorb heat and vaporize, to achieve the purposeof cycle refrigeration.In this way, the refrigerant completes a refrigeration cycle through four basicprocesses of evaporation, compression, condensation, and throttling in thesystem. | |
Air Circulation | ||
| The centrifugal fan is installed at the rear of the chamber body, and the air is uniformly distributed through the air outlet. Air circulation adopts air outlet at top and air return at bottom, and the wind speed and pressure are in compliance with the test standard, and the temperature is stabilized at the moment of switching. The high-quality centrifugal fan is used to strongly supply air circulation, making the temperature distribution in the test area uniform. | |
Controller System | ||
| The PID controller as the main control unit to command, operate, detect and redistribute the various components of the equipment to achieve maximum effective use. The temperature control adopts P.I.D. S.S.R. system synchronous coordinated control, which can improve the stability and life of the control components and interface. Screen display function: LCD display, which can display test conditions (including temperature section, cycle number, running time and remaining time, etc.). | |
Temperature Sensor | ||
| PT-100 Class A sensor, real-time accurate detection and display of temperature changes at 0.001 degrees. | |
Wiring System | ||
| Voltage 380V 50Hz 3 phase. L1, L2, L3, PE, N, grounding protection. Standard 2m long cable | |
