5 Parts Of Working principle of automobile air conditioning compressor
The air conditioning compressor in a vehicle is responsible for circulating refrigerant throughout the AC system, compressing it to increase its pressure and temperature. This process enables the refrigerant to release heat in the condenser and then cool down in the evaporator, drawing heat from the vehicle's cabin. The compressor is controlled by various components to ensure efficient operation and maintain desired cabin temperature.
1.Compression Process:
- The compressor draws in low-temperature, low-pressure refrigerant vapor from the evaporator outlet.
- It compresses this vapor into high-temperature, high-pressure refrigerant vapor and discharges it from the compressor.
2.Components and Their Functions:
- Evaporator: Located in the indoor unit, it absorbs heat from the room, causing the liquid refrigerant within its pipes to evaporate into gas.
- Compressor: Acts as the main engine driving the air conditioner, located in the outdoor unit. It is responsible for compressing the refrigerant.
- Condenser: Reduces the temperature of the high-pressure, hot refrigerant vapor from the compressor. Heat is released, turning the hot vapor back into a liquid.
- Expansion Valve: Located between the evaporator and the condenser, it controls the amount of refrigerant flowing towards the evaporator.
3.Control Mechanisms:
- Pressure Control: Pressure sensors monitor the refrigerant pressure at various points in the system. If pressure becomes too high or too low, the AC control module activates or deactivates the compressor accordingly.
- Temperature Control: Temperature sensors measure the cabin temperature and compare it to a set point. When the cabin temperature exceeds the set point, the AC control module engages the compressor to cool the air.
4.Types of Compressors:
- Fixed Displacement Compressor (CC): The displacement of the compressor increases proportionally with the increase in engine speed. It cannot automatically change its power output based on cooling demands and can significantly affect engine fuel consumption.
- Variable Displacement Compressor (VD): Adjusts its displacement to match cooling demands. This allows the AC system to optimize efficiency and prevent over-cooling or overheating.
5.Working Cycle:
- The refrigerant cycle begins with the evaporator, where the liquid refrigerant absorbs heat and evaporates.
- The hot refrigerant gas is then compressed by the compressor, increasing its pressure and temperature.
- This high-pressure, hot gas enters the condenser, where it releases heat and condenses back into a liquid.
- The liquid refrigerant then flows through the expansion valve, reducing its pressure and temperature, before returning to the evaporator to start the cycle anew.
In summary, the car air conditioning compressor is a crucial component that drives the refrigerant cycle, enabling efficient heating and cooling within the vehicle's cabin. Its performance is tightly controlled by various sensors and modules to maintain desired conditions.
