Chiller’s water outlet temperature is controlled based on the average temperature of all units in the module
▪
The module with the highest priority starts first. When the module reaches full load, the next module with the next priority starts
▪
When the module with the lowest priority operates at minimum capacity and the water outlet temperature approaches set temperature,
compressors stop
