AC cooling dies when car stops

I have Corolla 98 running on CNG. 3 months back got its A/C serviced and filled the gas as well. A/C cooling is extra ordinary when the car is running, but when the car stops in hot conditions on signal or in traffic jams, the A/C colling gradually becomes negligible and if car is stopped for a longer time, compressor also stops as i feel a sudden drop in the race/RPM. I got compressor and gas also checked, but these are OK.

Can someone suggest what could be the problem as I don't want the mechanics to do experiments with the A/C.
Thanks.

When idle you need 2 things for strong cooling as far as i know.

1 - Compressor that is working good on low rpm.

2 - The condensor should be clean the condensor fan should be running at good rpm and if you dont than put multi aisle condensor that will not only remove any load on your car also increase cooling by 30%. Most of the new cars have multi aisle not sure about yours.
