Ventilation radiators, heat emitters where cold ventilation air is brought directly from outdoors into the room via heated radiator surfaces, are becoming more and more common in Scandinavia. Because these systems combine both heating and ventilation several interesting aspects arise that may be used to save energy and improve indoor thermal climate. The heating aspects in wintertime have been discussed in previous papers from KTH STH. This study investigates whether ventilation radiators may be used for cooling in summertime. Results from the study show that condensation of water is the main problem to tackle when ventilation radiators are used for cooling purposes. It is difficult to avoid condensation, especially inside the ventilation channel where incoming ventilation air comes into contact with chilled radiator surfaces. The problem increases with increased temperature difference between radiator surface and ventilation air. This is why ventilation radiators seem unsuitable for cooling in summertime without risking condensation of water. However, if condensation of water is allowed in the ventilation channel only, ventilation radiators may be functional for cooling. The trick is to find a way to drain water from the ventilation channel to avoid hygiene problems.
