Cooling production has application in a considerable number of fields in human life, such as: food processing, air-conditioning, pharmaceuticals, etc. The conventional refrigeration system driven by the vapour compression cycle in general inhibits sustainable development due to it's association with high electricity consumption as well as global warming. Tri-generation can address this problem as it produces electricity, heating and cooling from a single fuel source, and it also uses an environmentally friendly working fluid. This thesis describes in detail the development of a residential tri-generation system based on ClimateWell® technology and a gas fired co-generation unit. Detailed design of a tri-generation system and a multi-tank cascade storage system has been developed. Based on the design, a residential tri-generation system has been installed and commissioned at the House-B of the TRCA, located in Vaughan, Ontario. The installed tri-generation system is instrumented with over 30 different sensors and the experimental data collected were analyzed to evaluate the performance of the system. It has been found that the multi-tank system is capable of preheating the incoming water main cold water by 6-7°C by utilizing the rejected heat of the tri-generation system. Experimental data show that the co-generation system has a thermal efficiency of 71% and the COP of the ClimateWell® system is 0.365. A TRNSYS model of the tri-generation system and the multi-tank storage system has also been developed and the models were validated with the experimental data. The models were also used to simulate the performance of the integrated system for different input conditions.
