Abstract

A computer simulation program called TRNSYS (Transient System Simulation) was used to model two air-conditioning waste heat recovery water heating configurations. The first model is a heat recovery unit (HRU) that utilizes an 80-gallon storage tank in conjunction with a conventional home air-conditioning system. The second model is similar to the first, except that there is an additional 80-gallon preheat storage tank. An attempt was made to compare simulation results with experimental field data. However, due to problems encountered during the field tests, such as equipment and/or instrumentation failure, there were not enough experimental data to make a rigorous comparison. The performance of the simulated systems was studied under different values of parameters influencing energy savings. The primary factor of mismatch between waste heat availability and hot water demand was analyzed and recommendations were made to minimize the mismatch.

The one-tank and two-tank models were compared against each other and the two-tank model was found to be more energy efficient and more economical. This was in agreement with the experimental results. In all cases, energy savings were shown to be higher during periods of large air-conditioning demand.
