Bus Con consists of a compressor, condenser, receiver-dryer, expansion valve, evaporator, and blower. Copper (or aluminum) tubes and high-pressure rubber hoses connect these components to form a closed system. When the refrigeration system is operating, refrigerant circulates within this closed system in different states. Each cycle involves four basic processes:
1. Compression: The compressor draws in low-temperature, low-pressure refrigerant gas from the evaporator outlet, compresses it into high-temperature, high-pressure gas, and discharges it from the compressor.
2. Heat Dissipation: The high-temperature, high-pressure superheated refrigerant gas enters the condenser. Due to the drop in pressure and temperature, the refrigerant gas condenses into liquid, releasing a large amount of heat.
3. Throttling: The high-temperature and high-pressure refrigerant liquid expands in volume after passing through the expansion device, causing its pressure and temperature to drop sharply, and then exits the expansion device as a mist (fine droplets).
4. Heat Absorption: The mist refrigerant liquid enters the evaporator. Since the boiling point of the refrigerant is much lower than the temperature inside the evaporator, the refrigerant liquid evaporates into gas. During the evaporation process, a large amount of heat is released... The automotive air conditioning refrigeration system consists of a compressor, condenser, receiver-dryer, expansion valve, evaporator, and blower.

The Bus Con refrigeration cycle has four basic processes:
1. Compression: The compressor draws in low-temperature, low-pressure refrigerant gas from the evaporator outlet, compresses it into high-temperature, high-pressure gas, and discharges it from the compressor.
2. Heat Dissipation: The high-temperature, high-pressure superheated refrigerant gas enters the condenser. Due to the decrease in pressure and temperature, the refrigerant gas condenses into liquid, releasing a large amount of heat.
3. Throttling: The high-temperature and high-pressure refrigerant liquid expands in volume after passing through the expansion device, causing its pressure and temperature to drop sharply, and then exits the expansion device as a mist (fine droplets).
4. Heat Absorption: The mist refrigerant liquid enters the evaporator. Since the boiling point of the refrigerant is much lower than the temperature inside the evaporator, the refrigerant liquid evaporates into gas. During the evaporation process, the refrigerant absorbs a large amount of ambient heat, and the low-temperature, low-pressure refrigerant vapor then enters the compressor.
The compressor cannot press out water. The water produced by the Bus Con during cooling occurs because the condenser surface temperature is much lower than the ambient temperature during operation. Water vapor in the air condenses on the condenser surface. To prevent this water from flowing into the room, air conditioners use a hose to direct the condensed water outdoors.
