In the context of indoor building temperature regulation, a controller calculates the inputs for the HVAC system that result in appropriate thermal comfort conditions. Additionally, if electricity prices are time dependent, these control actions will also impact economic expenditures. To improve economic performance, Thermal Energy Storage (TES) is typically used in conjunction with HVAC to tim...

Traditional fossil fuels lead to environmental problems and are also depleting. A significant portion of global energy consumption is due to building’s air conditioning. Nowadays there is a great attention toward renewable and sustainable energy sources to support the buildings energy requirements. In this study, a solar cooling machine was designed for a three-floor residential building under ...

Abstract In this study the first and second laws of thermodynamics are evaluated for a single effect absorption chiller. Entropy generation COP selected as objective functions their variations studied by varying generator temperature various condensing temperatures. For purpose, enthalpy entropy data super-heated steam, saturated steam water formulated in mathematical equations. Also to provide...
