How AC is affected by Outside temperature


Recommended Posts

Very interesting topic.

Generally people face problem in the AC specially when its summer. The compressor of the AC gets overheated because of the hot temperature which results in the level of refrigerant going down. So it is always advised to maintain the level of refrigerant in the car by proper maintenance of your car.

Its not the compressor which is getting hotter in summer and u face less cooling. It is because in high temperature you can not shift heat easily from inside of the car to out side of the car via condensor (heat exchanger). Many models have super design and this heat is not a problem , but some make and models really perform bad in summer. Properly cleaning the fins can increase the cooling better. Regards

Hmm, this is really interesting to know that to fix this borderline cooling issue we need to upgrade the condenser and not the compressor.....! Am I right?

Generally speaking yes. even condensor can be converted to water cool for better cooling. 

But there are other things to tackle.

Mechanical fitting of new condensor

High air flow for bigger condensor

Matching of peessure losses

That is the reason i said some car designs are superb as they properly maintain super heat and sub cooling. while other cars just maintain fuel ratio only.

Same bad car will give u superb cooling in winter with the same compresor because it can reject heat easily in  winter time.

With kind regards.
