3.5 Summary of Chapter 3This chapter described the micro-trigeneration system, the basis of ESP-r plantcomponents and networks, plant network design and the implementation of control:the strategies used to control the indoor temperature of each individual apartment inboth the 3 household and the 6 household building were also presented and explained.The core of this chapter outlined the development of a new generic model for asingle-effect lithium bromide-water absorption chiller which, in contrast to mostdynamic models that rely on complex modelling and calibration of the internalcharacteristics of the chiller, was developed in such a way as to enable its calibrationas a single unit. Furthermore, whereas many other models require re-calibration ofthe internal components in order to represent different chiller types, the modelpresented in this research can be calibrated simply by measured data of the inlet andoutlet temperatures of the three water circuits flowing in and out of the chiller. Themodel is therefore flexible and adaptable for calibration with other chiller data.Verification of the model indicated that the model provided a good approximation tothe measured performance of the real chiller and its performance was very similar tothat of another model. Finally, the integration of the model into an ESP-rtrigeneration model and its variants was described.132
