Effect of Evaporator Pressure on Volumetric Efficiency of AC Compressor

Volumetric efficiency is the ratio of actual volume of refrigerant gas drawn into the compressor cylinder to the swept volume of the cylinder. It is an important parameter for evaluating the performance of AC compressor as it determines the amount of refrigerant gas that can be compressed in a given time.

Effect of Evaporator Pressure on Volumetric Efficiency

When the evaporator pressure increases, the volumetric efficiency of the AC compressor increases. This is because the mass flow rate of refrigerant gas drawn into the compressor cylinder increases with the increase in evaporator pressure. This results in more refrigerant gas being compressed and delivered to the condenser in a given time, thereby increasing the cooling capacity of the AC system.

Explanation

The evaporator pressure is a key parameter that affects the volumetric efficiency of the AC compressor. The evaporator pressure is the pressure at which the refrigerant gas is absorbed by the evaporator from the surrounding air. When the evaporator pressure increases, the pressure difference between the evaporator and compressor cylinder increases. This results in an increase in the mass flow rate of refrigerant gas drawn into the compressor cylinder during the suction stroke.

As a result, more refrigerant gas is compressed and delivered to the condenser during the compression stroke. This increases the cooling capacity of the AC system, as more heat is removed from the surrounding air. Therefore, the volumetric efficiency of the AC compressor increases with the increase in evaporator pressure.

Conclusion

In conclusion, the volumetric efficiency of the AC compressor increases with the increase in evaporator pressure. This is due to the increase in mass flow rate of refrigerant gas drawn into the compressor cylinder during the suction stroke. This results in more refrigerant gas being compressed and delivered to the condenser, thereby increasing the cooling capacity of the AC system.
