| Summary: | High indoor temperatures during the early night cause a reduction in the occupants’ comfort, resulting in a higher energy and cost demand. This in turn calls for a study on the usage of a specialised cooling system for night time usage that utilizes natural resources. Not many studies have been conducted to examine the feasibility of a water cooled wall. This study aims to address the issue. The objective of this research is to study the feasibility of a water cooled wall to reduce indoor temperatures at night. This is done through removal of heat stored in the walls by countering the heat storage and time lag effects. This system is also intended to reduce the temperature differences between the indoors and outdoors during the night. The methodology of this study includes a review of the relevant heat transfer principles, a look at the existing passive cooling strategies, selecting a concept and design, building and testing a model, and collecting and analysing the results obtained from the tests. A CLTD calculation of the cooling load for a UTP hostel room was also calculated. It is found that a water cooled wall is feasible and more studies and research should be conducted to further improve the designed system. |
