Hi Taz ,

Thanks for your prompt reply.You explained very well that how can a system fail due to overcharging.But number of times , either chiller or Air Conditioner works when the gas is overcharged up to certain limit.

My question is , how overcharging of refrigerant in the chiller or Air conditioning (window,split,Automobiles) effects their cooling efficiency ?? What change occur in the various parameters that leads to decrease in efficiency of system.

Thanks for your cooperation.Looking forward for your answers.

Cheers

Sumit
