Low Cost Humidity Controlled Air-Conditioning System for Building Energy Savings in Tropical Climate

The viable solution to the high latent load that naturally occurs in tropical regions requires an alternative system that runs at relatively low energy consumption yet be able to provide indoor thermal comfort by effective handling of the excessive humidity. Although the existing outdoor air treatme...
