Advances in chiller design significantly improve efficiency. However, keeping chillers operating efficiently is still very much in the hands of contractors and service representatives. “High-tech” chillers are built with narrower tolerances; service and upkeep are more crucial than ever to keep efficient chillers operating at peak conditions.
Your first step toward maintaining an efficiently run high-tech system is the daily log. Old-fashioned as it may seem, this log allows you to build a history of operating conditions including temperatures, pressures, fluid levels, and flow rates. True, microprocessor controls are increasingly given the responsibility for recording these statistics. But there is still no substitute for a daily read of controls in the chiller room.
