NOTE:
1. Capacity: Cooling Capacity (kW)
Input: Compressor Input Power (kW)
EER: Capacity/Input (kW/kW)
2. Operating Conditions:
Chilled Water Outlet Temperature: 7°C
Water Flow Rate: Constant
3. Above Table shows the percentage of Capacity, input and EER based on the standard condition.
Therefore, each value can be calculated as below example:
Example: Model RCUE100 CLG2
Standard Condition
Condensing Temperature 40 °C,
Capacity 80%
Capacity: 290 kW Capacity: 290 × 0.8 = 232 kW
Input: 84.8 kW Input: 84.8 × 0.66 = 56.0 kW
EER: 3.42 EER: 3.42 × 1.21 = 4.14
4. Control marked (*) is available by the optional selection switch DSW7-3 / ON: Minimum Load Extension.
