Compressor is hot due to gas compression, and the gas then cooled in condenser. AC installed in tropical climate. Why compressor have insulation barrier?
$\begingroup$ Stop ambient heat entering...? Or noise reduction? $\endgroup$– Solar MikeMay 4, 2018 at 11:08
$\begingroup$ Ambient heat cannot entering since compressor temperature must be higher than ambient. This is also happened to be R-32 refrigerant (higher condenser temperature). $\endgroup$– RainerJMay 4, 2018 at 14:21
$\begingroup$ But heat can go back to the environment which you are trying to cool... As pointed out by Olin... $\endgroup$– Solar MikeMay 4, 2018 at 14:26
$\begingroup$ You mean, heat go to outlet of condenser. That's can make sense, but should be the outlet condenser tubing to be insulated. I'm thinking why don't we air cooled the compressor also. This discussion might lead to some system improvements. $\endgroup$– RainerJMay 4, 2018 at 14:29
$\begingroup$ No, that unit is trying to cool the space it is in.. if the heat from the compressor gets back into that space then it is wasted work, so i sulate the compressor so the heat is taken away by the fluid to the condensor... $\endgroup$– Solar MikeMay 4, 2018 at 14:32
Knowledgeable service man said it was for noise reduction.
Just guessing, but some possibilities:
- To reduce noise.
- To reduce heat exchange in places other than where it is wanted/used.
