Dynamic simulation of a complete solar assisted conditioning system in an office building using TRNSYS

To minimize environmental impact and CO2 production associated with air-conditioning system operation, it is reasonable to evaluate the prospects of a clean energy source. Solar energy can drive an absorption chiller in order to satisfy the cooling needs of buildings. The objective of this work is to build a simulation environment that can evaluate accurately the energy consumption of an air conditioning system including a solar driven absorption chiller. This environment includes the absorption chiller itself, the rejection system, solar panels field, heater, storage devices, pumps, heatingcooling networks, emission system and building. TRNSYS software modular approach (Crawley, 2008).provides the possibility to model and simulate this complete system. Different strategies are proposed to minimize consumption for airconditioning. Primary energy consumption for the whole building is presented by field (lighting, appliances, …)
