Selection Procedures
To rate the performance of the mini chiller at different conditions, the System Performance Table
which provided in the following pages should be referred to. The performance data is based
on ambient temperature and leaving water temperature. To select a mini chiller, the following
information is request:
1. Cooling or Heating load
2. Leaving water temperature
3. Entering water temperature

By knowing the above data, the suitable unit can be selected though System Performance table.
The water pressure drop can be found in the Pump Curve. For glycol application, correct the
capacity from Correction Factor (Glycol) table.
Example:
System load = 20 kW cooling capacity. Entering water temperature 12°C and leaving water
temperature is 7°C. Ambient temperature is 30°C. Model: cooling only split type mini chiller, and
single phase power supply.
1. Select the appropriate performance table based on mini chiller to be used. Read the “Total”
