In order to investigate the feasibility of a combined heating, cooling, and power generation system in the residential sector, an integrated system was designed and installed at the Archetype Sustainable House (ASH) of the Toronto and Region Conservation Authority (TRCA). A Stirling engine based cogeneration unit was used to produce the thermal energy for a thermally driven chiller. The engine supplies hot water up to 95°C. The overall efficiency of up to 90% is determined for the cogeneration system. A thermo-chemical accumulator provided by the ClimateWell AB, was installed and connected to the cogeneration unit. The experimental coefficient of performance (COP) of this chiller during the test period was less than 0.4. Since the ClimateWell chiller rejects heat during both charging and discharging processes, a heat recovery system using three cascade tanks and an outdoor fan coil was designed and installed to utilize the waste heat, for domestic hot water production. A complete TRNSYS model of the tri-generation system was used to verify the experimental results.

Power Generation System

A 1 kW proton exchange membrane (PEM) fuel cell power system with heat and water recovery was successfully integrated. This power generation system is designed for the stationary application. The waste heat can be recovered into hot water, which store in a tank with temperature higher than 60°C. This hot water may be suitable for bath and kitchen use in a small family. The adjustment for the power generation system is now on going and promoting. Now 38% in the electrical efficiency (AC110V output) for the system is achieved. With waste heat recovery involved, the system will potentially have overall energy efficiency more than 70%. In order to optimize the system, some technologies should be studied and pre-tested before integration work, which mainly included water management for the fuel cell stack, water and thermal conditions on the performance of fuel cell, air and water pumping power needed for the fitting of optimum system performance.

Integration Strategies

Solar aided coal-fired power generation system (SACFPGS) combines solar energy and traditional coal-fired units in a particular way. This study mainly improves the solar thermal storage system. Genetic algorithm is used to optimize the SACFPGS. The best integration approach of the system, the collector area, and the corresponding thermal storage capacity to replace each high-pressure extraction are obtained when the amount of coal saving in unit solar investment per hour is at its largest. System performance before and after the improvement is compared. Results show that the improvement of the thermal storage system effectively increases the economic benefit of the integrated system.
