The Refrigeration Cycle
1. A high-pressure liquid refrigerant is pressurized, converted into a vapour and forced into a condenser.
2. The condenser initiates a cooling process to cool down the gas, which condenses into a liquid.
3. From there, it enters the expansion valves, rapidly reducing pressure and temperature, causing it to turn into a low-pressure, low-temperature liquid.
4. It then enters the evaporator, where it absorbs heat, allowing the refrigerant to evaporate back into the compressor to start the vapour compression cycle all over again.
