Efficiency control
DVM CHILLER's water outlet temperature is controlled according to the water outlet
temperature average value of all units which operates by pumps in a module. However,
if you set "Use" for an external water temperature sensor, it controls the water outlet
tmeperature according to a temperature value from the sensor.
Only one unit with the highest priority operates, and if the unit operates with the
optimum efficiency, a unit with the following priority will operate.
When all units reach efficient operating condition, each unit operates at capacity
between efficient operating condition and the maximum capacity condition.
When all units reach efficient operating condition and the water outlet tmeperature
reaches close to the set temperature, the unit with the lowest priority controls descent of
compressor operating capacity.
