WebSep 15, 2024 · The Evaporator. The evaporator does the exact opposite of the condenser. Instead of turning the refrigerant from gas to liquid, it turns the refrigerant from liquid to gas (thus the name “evaporator”). Instead of expelling heat, it absorbs heat and turns the air cold around it. This is where the “conditioning” of the air occurs. WebFeb 1, 2024 · The method uses the temperature differences between the calculation and measurement to update the liquid mass flow rate. Thus, the method can predict the liquid refrigerant inlet mass flow rate in each flow path, i.e., each microchannel tube. The outlet pressures of each path are assumed to be uniform.

WebDec 14, 2024 · Standard 15 classifies variable refrigerant flow systems as “direct systems” and “high-probability systems.” This means the VRF indoor unit evaporator coils are in direct contact with the conditioned air stream and have a high potential to leak refrigerant into the occupied space.
