Designing energy plants the smart way

摘要

A critical review of the expected spectrum of operating loads, including the maximum design, average, low, and minimum loads, is necessary to develop a generating plant design. Low-load control is essential for efficient operation of heating and cooling plants and providing comfort during low-load and changeover conditions between heating and cooling. Complaints from occupants to maintenance personnel often peak during times of low load. Generally, low-load and changeover conditions occur for many hours during a year, many more times than high and low design loads. Low-load and changeover occurs when the outside temperature is between 45 and 75 F.
