DESIGN FOR SOLAR HEATING IN HILL SHELTERS
Product: Design of trombe wall system for solar passive heating of buildings for comfortable temperature during winters.
Application: Built-in solar heating system for residential and office buildings in hilly/cold regions
Feature: The house is constructed as per normal practice. The south wall is painted black and covered with plain 4 mm thick double glass panes. Openings are provided in the wall near the floor level as well as the ceiling level. The air trapped between the wall and the glass gets heated due to the solar radiation absorbed by the wall. Due to temp. difference across two sides of the wall, the exchange of air takes place by stack effect. The room gets heated inside through conduction as well as convection. The indoor temp. of 20-22oC is attained while the outside temp. is 10oC at a particular point of time
Commercialisation: Demonstrated at a building in Nainital
Economy: Rs. 300/m2 wall area.
Investment: --------
Equipment: Nil
Raw materials: Glass panes 4 mm, wooden battens, black paint.
Institute: Central Building Research Institute.
