Air-conditioning system
Installation of coolant-filled heat pipes in the air-conditioning system rather than the traditional air-mixing thermal heat wheel, to eliminate the risk of cross contamination between exhausts from and fresh air supply for the Biohazard Level 3 laboratories and animal houses. The heat pipes act as a medium to extract "cooling" energy from the exhausts and use this extracted energy to pre-cool segregated incoming fresh air.
Variable frequency drive pumps and fans in the chilled water and air handling system were installed to use less energy under partial load conditions.
The centralized refrigeration system with zero ozone depletion, serves 11 cold rooms, saves energy through its water-cooling design.
Indoor Air Quality
An automatic detection and control system that ensures optima indoor air quality in the lecture theatre and multi-purpose hall by varying fresh air supply based on detected level of CO2 output by occupants.
Car-park ventilation systems
Enclosed car-park ventilation systems equipped with carbon monoxide sensors, that automatically adjust exhaust air flow rated to ensure that carbon monoxide is maintained at an acceptable level.
