Current Projects on ITE:
Design of a Passive Cooling System For an Office Based on Nocturnal Cooling and Thermal Mass Principles (Engr. Jose Reyes, ongoing M. Eng. M.E. thesis). A passive cooling system intended for the Mechanical Engineering Office of CIT is proposed.� The operating principle of the system is based on nocturnal cooling� and thermal mass principles.� At night ambient air is allowed to pass beneath the cold roof of the building and the cooled air is then introduced into the office room.� The cooled air first flows along the vertical walls (concrete) of room and then along the concrete floor of the room thus cooling these thermal mass. During day time the ambient air is cooled by these thermal mass and thus cooling the occupants of the room.� The study involves gathering of data needed for the design, such as, temperature of the roof at night time, the heat gain of the room during day time, the ambient air temperature, velocity, and humidity.� A model that can simulate the temperature inside the room during day time will be developed.� Feasibility of the design will be determined based on the results of the simulation.
Optimum location of a window-type air-conditioner in terms of thermal comfort of occupants: (Engr. Roberto Base; ongoing MEP thesis)� Thermal comfort of a person in an air-conditioned room depends primarily on temperature and humidity of room air.� The velocity and turbulence of the air stream are added factors that affect the degree of comfort of the person.�� The values of these factors vary with the location of the air-conditioning unit in relation to the occupant.� Until now, -particularly for the use by our local engineers, it can be said that there are no design rules that determine the optimum location of the window-type air-conditioner.� This study aims to determine the optimum (vertical)� location of the air-conditioner.� The location will be evaluated �using the Comfort Index developed by Fanger for estimating the perceived thermal comfort level of the occupants.� Velocity and temperature distribution and the humidity level inside the room will also be measured.
