- Abstract
- The Natiomal Bureau of Standards is presently reviewing the Definitive Performance Criteria for Residential Solar Heating, Cooling and Hot Water Systems. In support of that effort, this report describes a study designed to quantify the effect of daily domestic hot water loads and system design on the performance of multi-family solar domestic hot water systems. Two multi-family solar domestic hot water systems judged representative of the systems funded by the HUD Residential Solar Demonstration Program, along with possible modifications to these systems, are modeled using the TRNSYS simulation computer program. The effects of collector array efficiency, storage capacity, and distribution heat losses were studied over a range of daily domestic hot water loads from 11 to 190 L/day-unit.
