Title

An Optimal Control Approach For Determination Of The Heat Loss Coefficient In A Domestic Water Heating System

Abstract

Integral collector storage (ICS) solar domestic water heating systems are an alternative to help meet the hot water energy demands in a household. In order to evaluate the potential benefits and contributions from the system, it is important to be certain that the modeling scheme is as accurate as possible. The overall heat loss coefficient (Uloss) plays an important roll in such a scheme and in the performance prediction methodology of the ICS. This paper presents the results of an investigation of the application of optimal control theory to find how Uloss varies with time, for a particular non-concentrating ICS system. The time-varying Uloss obtained was used in a proposed model, and the resulting simulated ICS performance was compared to the real measured performance and the simulated case when U loss was time-invariant. After comparison, it was determined that the use of a time-varying Uloss in the modeling scheme significantly improves the ICS performance prediction. © 2010 AACC.
