  1. (a)

    From 1 July 2016, the seasonal energy performance ratio (SEPR) of process chillers shall not fall below the following values:

    Heat transfer medium at the condensing sideOperating temperatureRated cooling capacityPA Minimum SEPR value
    AirMedium PA ≤ 300 kW2,24
    PA > 300 kW2,80
    Low PA ≤ 200 kW1,48
    PA > 200 kW1,60
    WaterMedium PA ≤ 300 kW2,86
    PA > 300 kW3,80
    Low PA ≤ 200 kW1,82
    PA > 200 kW2,10
  2. (b)

    From 1 July 2018, the seasonal energy performance ratio (SEPR) of process chillers shall not fall below the following values:

    Heat transfer medium at the condensing sideOperating temperatureRated cooling capacityPA Minimum SEPR value
    AirMedium PA ≤ 300 kW2,58
    PA > 300 kW3,22
    Low PA ≤ 200 kW1,70
    PA > 200 kW1,84
    WaterMedium PA ≤ 300 kW3,29
    PA > 300 kW4,37
    Low PA ≤ 200 kW2,09
    PA > 200 kW2,42
  3. (c)

    For process chillers intended to be charged with a refrigerant fluid with a global warming potential lower than 150, SEPR values can be lower than the values indicated in points 1(a) and (b) by a maximum of 10 %.
