Giving 5 ...May 15, 2017 · Excessive or high superheat is an indication of insufficient refrigerant in the evaporator coil for the heat load present. This could mean that not enough refrigerant is entering the coil or this could also indicate an excessive amount of heat load on the evaporator coil. R410A compressor is known to have a high pressure-ratio and uses polyolester (POE) lubricants. R290 is suitable for POE lubricants [7]. Based on our literature survey, only a few studies have analyzed the energy and exergy of ACs utilizing R410A instead of R290. Therefore, this study focused on analyzing the energy and exergy of …Superheat should be checked after the compressor has run continually for at least ten minutes to allow the system refrigerant and oil to settle. ...
