Practical Experiences from the USE of a Method for Active Functional Tests and Optimization of Coil Energy Recovery Loop Systems in AHUs
Abstract
A method, based on simulation models, for active functional tests and
optimization of coil energy recovery loop systems in Air Handling Units
(AHUs) have been developed and a first version implemented in the
program Engineering Equation Solver (EES). The heat recovery in this
kind of systems is often much lower than expected. The main reason for
the poor efficiency is faulty fluid flow in the recovery loop. The efficiency
can in many cases be raised by tenths of units of percentage. This paper
describes experiences from one example of use of the EES based tool in
practice, to determine the correct fluid flow. Also, there is a discussion
about the measurements in respect of needed accuracy and other related
questions.
