• Phase 1: Refrigerant Compression: The compressor increases the pressure and temperature of the refrigerant (in gaseous form). This hot gas is then pushed to the condenser. Here, the refrigerant releases heat to the surrounding environment and condenses back into liquid form under high pressure.
• Phase 2: Throttle and pressure reduction: The liquid refrigerant passes through the expansion valve. This process reduces the pressure and temperature of the refrigerant to extremely low levels before entering the main cooling unit.
• Phase 3: Evaporation and heat absorption: The refrigerant at low temperature is introduced. industrial refrigeration (Evaporator). Here, a forced-air fan blows air through the evaporator, and the refrigerant absorbs all the heat energy from the goods and the space inside the container, causing the ambient temperature to drop to the set level.
• Phase 4: The cycle repeats: After absorbing heat, the refrigerant reverts to a gaseous state and is drawn back into the compressor to begin a new cycle. This process occurs continuously and automatically to maintain the ideal temperature range.
