dc.description.abstractThis study was conducted with the objective to better understand the energy implications and performance of the heat pipe integrated Air Conditioning and Mechanical Ventilation (ACMV) system in tackling the humidity problems faced in buildings in the tropical climate. The study was carried out on two different ACMV system designs, namely the conventional 20 percent outdoor air intake design and 100 percent outdoor air intake design. The facilities investigated are CeLS (100 percent outdoor air intake) and CQT (20 percent outdoor air intake) and both are operating 24 hours a day, 7 days a week (24/7). The study emphasizes on the effectiveness of the heat pipe technology in enhancing the ACMV performance and the corresponding energy savings achieved in relative to an ACMV system without heat pipe, which would require additional cooling and active reheating to attain the same space conditions. Analysis on the performance of heat pipe integrated ACMV systems in providing a good Indoor Air Quality (IAQ) in terms of air temperature and Relative Humidity (RH) was also conducted to test its applicability in tropical climate Singapore. The raw data was collected from the ACMV systems in the respective facilities and plotted on a psychrometric chart to obtain the relevant data required for the energy calculations and analysis. From the results, it is seen that the application of heat pipe technology has generated significant energy savings through passive pre-cooling and reheating of the air. Furthermore, it was also found that higher savings were achieved in an average afternoon due to the high air temperature which allows greater pre-cooling to take place and reduces the active cooling load. Over the study period of seven days, the indoor air temperature and RH were observed to have satisfied the facilities’ stringent requirements. This has indeed proven that the heat pipe integrated ACMV systems were very successful in tackling the humidity problems faced in buildings in the tropical countries. Most importantly, the monthly economic savings per square metres (sqm) achieved in CQT was found to be significantly higher than the savings achieved in CeLS, indicating that heat pipes can perform better in the conventional 20 percent outdoor air intake ACMV system design. Last but not least, there are several limitations that were faced in the progress of this study: they include the reduced scope of study due to time and technical constraints, the different approach to energy savings computation due to the different AHUs sizing and reduced study period due to the delay in gaining approval to access CeLS.
