In this short podcast, Bryan explains what the heat of compression is and why we should care about it as HVAC/R professionals.

More heat is rejected in the condenser than absorbed in the evaporator coil, and that's because the compressor adds heat. That added heat is called "heat of compression." That heat does NOT contribute to the net refrigeration effect (NRE), as it doesn't contribute to cooling.

When we compress something, we increase the system entropy during that process. Entropy is the waste and disorder associated with work. There is some inefficiency, which we see in the form of…
