(1994) Tennakoon, Susila MalkanthiThesisThe work documented in this thesis is concerned with the modelling of the largest solar installation in Australia at the Yulara Resort at Ayers Rock. This solar system was designed to supply the domestic hot water and space heating for the large tourist accommodation complex at Ayers Rock. An energy audit performed in 1991 showed that the solar system was not operating effectively and that during summer the collectors were overheating. A model of the system was developed to study the system and to recommend ways of improving the performance of the system and to avoid operational problems. The thesis also includes a detailed description of the development of a program to simulate the combined solar, heat pump and ice-on-coil type ice storage system used at the Yulara resort. The space heating system at Yulara consists of an ice-on-coil type ice storage system. In this study the solar thermal software package, TRNSYS (transient process simulation program) was used to model the system. Since there was no component subroutine to model the heat pump and ice storage system in TRNSYS, a subroutine was developed to model the time variable performance of an ice storage and heat pump system for this installation. Studies of the system using model results are presented. The system was reconfigured to study ways of improving the performance. The results showed that the system could be improved by using a gas boiler rather than the heat pump ice storage system, lowering the thermostats that control the solar input to the domestic hot water system and keeping the set temperatures of the domestic hot water system at a higher level. The results also showed that overheating of the collectors in summer could be avoided by storing excess solar energy during the day and dumping it to the atmosphere during the night.
