Simulates a kitchen for a study of indoor air quality. An extractive FTIR technique was used to measure combustion products from unflued combustion from a gas cooker in a ventilated room. On a comparison of the results with those from conventional instruments, the FTIR technique showed good agreement. The study incorporated the obscuring of the spectrum due to the effects of H2O and carbon dioxide and detection limits. The conditions in the room were investigated using CFD.
States that when used with ice storage systems, cold air distribution systems are popular since they require less operating and capital costs. Stresses the importance of a consideration of occupant comfort. The study looked at air circulation and temperature distribution in a room, considering different orientation, velocities and sizes of jet for a given vertical location of air inlet and outlet on opposing walls. A control volume method was used to solve the Navier-Stokes equations and an energy equation in two dimensional rectangular Cartesian coordinates.
In Switzerland, even if the average daily temperature rarely exceeds 25º C during the summer months, more and more cooling plants are being installed in administrative buildings. The CUEPE participated as experts in some realisations that showed (simulat
Discusses methods of overcoming the limitations of algebraic equations with small-scale physical and network flow models, as well as computer-based zone and CFD models.
