Energy conservation projects for General Instrument of Taiwan

Abstract

High energy costs are providing an incentive for industry in Taiwan to conserve fuel. A major consideration is to reduce energy consumption used in heating, cooling, and illumination of the workplace.

This report consists of three different projects concerning energy conservation opportunities for one industrial plant. Project I describes the installation of a Heat Recovery Wheel in order to recover cooled exhaust air. Project II describes the installation of water coils for recovering the waste heat of furnaces to preheat hot water. Project III depicts the modification of fluorescent lighting so as to improve the illumination level and also reduce the energy consumption in lighting and in air conditioning.

It is very important to evaluate each project on its economic merits. This energy conservation opportunity analysis includes a construction or implementation cost estimate and an estimate of potential energy savings. With those two values, the most convenient economic analysis is the simple payback relation of costs and savings.
