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.
WebJan 14, 2024 · Net refrigeration effect (NRE) is the quantity of heat that each pound of the refrigerant absorbs in the refrigerated space to produce useful cooling. That’s a pretty vague definition. We know that it’s an amount of heat in processes that take place within the evaporator. Still, the phrase “useful cooling” seems rather broad. WebDoes high superheat mean low charge? Low Charge- If refrigerant charge is low, the superheat will be high. The low side pressure will be lower than normal. This indicates the refrigerant absorbed too much heat while traveling through the evaporator. Over Charge- If refrigerant charge is high, the superheat will be low.
