Performance analysis on the thermosiphon beam air conditioning and mechanical ventilation system

Air Conditioning and Mechanical Ventilation (ACMV) systems have been around for many years to provide cooling to many buildings around the world. However, due to the alarming rates of global warming, it is essential to develop new innovative ACMV technology to reduce the carbon emissions due to the electrical consumption of the ACMVs. This report is based on the Thermosiphon Beam’s Air Conditioning and Mechanical Ventilation (TB ACMV) system which is developed in a joint research program with the School of Electrical and Electronics Engineering (EEE) and Energy Research Institute at Nanyang Technological University (ERI@N). It aims to explain how the TB ACMV system differs from the conventional ACMV system like the VAV AHU systems. The TB ACMV system is very versatile in handling both sensible and latent heat loads by splitting it into two major components, the Dedicated Outdoor Air System (DOAS) and the Thermosiphon Beam (TB). It also works with a higher chilled water temperature than the conventional ACMV system, hence reducing the overall energy consumption. The TB ACMV system also aims to improve Indoor Air Quality (IAQ) as well as ensure the thermal comfort of the occupants. The report would elaborate on how the TB ACMV is being controlled and how it is able to meet the required space heat loads with varying external air conditions.Bachelor of Engineering (Electrical and Electronic Engineering
