IPLV shows more realistic performance of AC system

It shows seasonal coefficient of performance which is calculated by using 4 different COP under different conditions

IPLV (Integrated Part Load Value)

IPLV comparison according to ARI 550590-98 VRV 10HP air cooled model Chiller performance is cited from Japan Refrigeration Institute air cooled chiller data 13
