WebSep 15, 2024 · 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.

"WebASHRAE Journal.3 This analysis showed that designing a chilled-water system for a higher ΔT reduced first costs—due to smaller valves, piping, and pumps—and also reduced overall system energy cost. The results showed that the increase in fan energy due to the added coil surface was more than offset by the pump energy savings. " - Condenser evaporator system ashrae
