Optimizing TES (thermal energy storage system) chiller management.

Summary

The advantages to controlling chillers in this way are as follows: it provides exact control of leaving water temperature without losing any chiller capacity under all operating conditions; loss of normal capacity will be apparent immediately allowing correction of operating problems before they become severe; because the chiller is operated at maximum capacity, the chiller and auxiliary equipment operate fewer hours per season to obtain the same cooling production; most chillers will operate with less noise and vibration when operated at full load thereby causing less wear and tear on the equipment; using modulating valves and a recirculating line, a "bumpless" startup and shutdown of chillers, and unloading chillers before shutdown is possible.
