چکیده
The main objective of this investigation was to design and investigate a radiant panel cooling system on small scale building type (office) under the central Sudan climatic conditions so as to explore the benefits of radiant cooling systems over conventional air conditioning systems (Variable air volume systems). Transient heat conduction of building (finite difference method) was used to evaluate the simulation model. The computer program (Matlab) was used to calculate transient heat flow through the walls and ceiling (variable loads) of the conditioned space. Other heat loads of the conditioned space were determined by the standard ASHRAE method. The experimental verification was achieved by using a cooling system which consists of a water chiller unit, fan coil unit (ducted fan coil unit) and radiant cooling panels to evaluate the validity of the radiant cooling panel system. The experimental results showed that the ceiling radiant cooling panel system with dedicated outdoor air system saves power demand of 17.3% and 26.1% of VAV system in case if recirculation air and 100% fresh air are used in each respectively.
