Mechanical Systems Laboratory

Engineering
Civil and Architectural Engineering
Labs

The Mechanical Systems Laboratory is designed to control a set of operating conditions and is able to maintain indoor thermal conditions within a user-defined set range. Within the lab, two rooms (heating-mode room/cooling-mode room) are divided by an internal insulated wall to control heat transfer between the rooms. The purposes of the lab include:

  • Bringing students learning in Psychrometric processes in relation to the mechanical systems operation.
  • Students design closed-loop control for HVAC (heating, ventilating, and air conditioning) systems, which aim to maintain an indoor thermal comfort level for the occupants.
  • Training students with hands-on measuring equipment systems development utilizing raspberry pi, data loggers, and sensors:
    • Air temperature probe and globe probe to measure operative temperature.
    • Relative humidity probe to measure indoor air moisture content.
    • Pyranometer to measure direct and diffuse solar radiation.

Additionally, students can design control logics for automated building enclosure systems (e.g. operable windows with blinds) using low-code programming, and assess the performance of the developed systems utilizing the measuring equipment.
