مبدأ العمل (Step-by-Step)
- خطوة 1: Cooling water absorbs heat from the laser device and transfers it to the refrigerant through the evaporator.
- خطوة 2: The refrigerant vapor is compressed by the compressor into a high-pressure, high-temperature gas.
- خطوة 3: The hot refrigerant releases heat to the surrounding air or external water system through the condenser and condenses into liquid.
- خطوة 4: يمر سائل التبريد عبر صمام التمدد, reducing pressure and returning to the evaporator to complete the cycle. Sensors and controllers maintain closed-loop temperature control.
