Superheat for most systems should be approximately 10F measured at the evaporator; 20 ° F to 25 ° F near the compressor. Superheating. In thermodynamics, superheating (sometimes referred to as boiling retardation, or boiling delay) is the phenomenon in which a liquid is heated to a temperature higher than its boiling point, without boiling. This is a so-called metastable state or metastate, where boiling might occur at any time, induced by external or internal ... The first benefit is the ability to maintain the minimum stable superheat within the evaporator. Here's a quick break down. When an evaporator is "under-filled" with refrigerant, the superheat signal is high and very stable at the outlet of the evaporator. Only a small area of the evaporator is utilized, resulting in degraded performance.
