Article: Field testing of a supervisory optimal controller for an air-conditioning system.(Technical report)

INTRODUCTION

As the global warming issue becomes more serious, there is a growing demand for an air-Conditioning system that works more efficiently, trimming energy consumption in operation. In countries where an air-Conditioning system is operated under varying cooling loads throughout the year, a control system that can manage the air-Conditioning system, keeping optimal efficiency of the whole system for such a varying cooling load, is greatly needed. We have worked at achieving energy savings in individual equipment such as chillers, fans, and pumps, applying inverters and/or other local control devices. However, to achieve further energy savings, as already ...
