Protection of kitchen extracts.

The influence of an architectural design alternative (transoms) on indoor air environment in conventional kitchens in Taiwan.

This study investigates indoor air environment via the flow fields, temperature fields and air contaminants (carbon monoxide) distributions in conventional residential kitchens, and looks for effective methods to solve those problems through natural ventilation techniques. Numerical simulations of the physical problem under consideration have been performed via a finite volume method for solving the governing equations and boundary conditions.

Influence of ventilation systems on aerosol and vapour concentration in the kitchen.

During the experiments and under the experimental conditions, displacement ventilation with air outlets close to floor level were found to produce the lowest concentrations of hazardous substances and aerosols in the working areas of kitchen appliances when compared with mixed or displacement ventilation through ceiling outlets. Displacement ventilation with low-induction ceiling outlets achieved better results than mixed ventilation.

Oversized kitchen fans - an exhausting problem.

No longer relegated to the garage or the workshop, the search for more power is taking over the kitchen, as commercial-sized kitchen fans invade the home. The problem is, residential kitchens aren't regulated the way commercial kitchens are. This causes potential hazards when these huge fans are turned on.

The mystery of the burnt toast.

 False fire alarms cost lives and students are often the worst offenders because of their less than silky cooking skills. HAC reveals how an 'allergy' to washing up liquid led to an innovative demand ventilation solution at Nottingham Trent University.
