摘要：A new design of room cooler, working on capillary action has been described with relevant performance data, and compared with an existing type. Its cooling efficiency, volume output efficiency and overall efficiency are about 63%, 85% and 54% respectively. The necessity of periodic wetting of the cooling fabric surfaces has been avoided. Apart from its cheapness, simplicity and low running expenditure, it has been made reasonably free from risks, personal or otherwise. Detailed instructions and precautions for its proper use have also been included.
