Résumé

The authors describe an experimental investigation of the effect of low charge level of R22 on the performance of a 3-ton residential air conditioning system. The results are presented and discussed. They show that if a system is undercharged to 90% then the effect is small - a 3.5% reduction in cooling capacity and a 2% decrease in the COP. However, the system performance suffers serious deterioration if the level of charge drops below 80%. Economic analysis showed that the cost of properly charging an undercharged system at 85% charge level, can pay for itself in savings in 3-4 months.
