Controlled active mass for increased thermal comfort

The objective of this study was to evaluate the underlying physics and controlling parameters for designing a Controlled Active Mass (CAM) system. The purpose of such a system is to obtain a good thermal indoor climate and facilitate the use of energy sources with low environmental impact. The CAM system will be designed to cover the cooling demands for controlling the internal heat gains in a typical-sized office room for one person. The CAM unit will be constructed as a tank filled with water in which the level and temperature can be controlled depending on demand. Compared to other cooling systems such as passive cooling beams, the system should only be used when there is a cooling demand in the office. We also expect that the CAM system will be possible to achieve more energy savings and better indoor climate compared to other active mass systems.The objective of this study was to evaluate the underlying physics and controlling parameters for designing a Controlled Active Mass (CAM) system.
