PPC - Power Process Controller

Increasing the efficiency of a central cooling facility

The controller determines the actual cooling load for multistage and separated cooling machines running in parallel.

This cooling load is compared to the available performance of the cooling machine and is released based on the shortest running time and highest efficiency.

The PPC takes into consideration the back cooling temperature as limitation of the performance in case of high outside temperatures. It also includes the actual availability of possible malfunctioning cooling machines.

Only the combination which provides the highest efficiency of the actual load condition is switched on.
