Evaporator Approach: —

Formula used:

Approach = TLCW − Tevap sat

Explanation: Evaporator approach tells you the temperature difference between the leaving chilled water and the evaporator saturated refrigerant temperature. It is useful for reviewing evaporator heat-transfer performance, but the result should be interpreted with chiller type, load, flow, and measurement accuracy in mind.

Want to compare this result to last month, document changes, or hand this to a customer? That requires a structured log.
