Title: Performance and Greenhouse Gas Analysis of a Solar Adsorption Chiller for Canadian Residential Applications
Abstract: Space cooling makes up a significant portion of the peak electrical demand worldwide. A large electrical peak on the grid can cause fossil fuel and other non-sustainable power facilities to ramp up or turn on which produces excessive amounts of carbon dioxide. One way to reduce the cooling demand on the electrical grid is to use solar cooling technologies such as an adsorption chiller. Recent developments have allowed adsorption chillers to provide higher cooling power at lower hot water temperatures, allowing the technology to pair well with a flat plate solar collector. A performance map was generated from an experimental setup with a 16-kW silica-gel adsorption chiller and is used in a TRNSYS model to linearly determine the performance of the chiller at given inlet conditions. The adsorption chiller model was implemented into a full system model and the performance was compared among various cities in Canada. It was found that in Toronto, an adsorption system with a flat plate collector can reduce electrical consumption, annual cost of electricity, and greenhouse gas emissions from space conditioning by 40%, 49%, and 46% respectively, when compared to a system using a water to water heat pump. The adsorption system was found to be plausible in residential applications in Canada. Some future work is planned for optimizing the heat transfer to the hot water tanks from the solar collectors and chilled water storage.
