Our Tasks

• Energy-saving

• Provide comfort for study and interaction

• Non air-conditioned

• Include at least five features that shows understanding of the application of heat transfer processes (at least one feature of conduction, convection and radiation must be applied)

We have come up with the idea of metal plated tables and chairs. The reason for this idea is that since metal is a good conductor of heat, when the student rest his arms on the table or sits on the chair, the table and chair conducts heat away from the students body.

Changing the fluorescent light tubes to LED fluorescent tubes does not only reduces heat, it has other benefits:

• Produce less heat than fluorescent tubes, and thus also uses less energy

• Uses less energy than fluorescent tubes• Last longer than fluorescent tubes ,thus

saving money in the long run as it requires changing less frequent. One LED fluorescent tube lifetime equals to 6 fluorescent tubes lifetime.

Our idea is to install air vents at the top of the classroom. This is to draw the warm air out from the classroom to the outside. This works as hot air rises. Thus this eliminates the warm air in the classroom.

The following slides will show the diagram and layout of our idea.

Our following idea is to have water sprays integrated with the fans. These sprays will spray out a mist of water occasionally and the water droplets would fall on the students’ body. The water droplets will act like sweat, and the wind from the fans would cause evaporation, thus cooling the body of the students.

Our last idea is to install ventilation fans in the side of the wall that is facing the outside. This is to draw in the cool air from the outside and into the classroom, especially in the morning as the air is damp and cooling. As the cool air comes in, it will also help push out the warm air.

The following diagram is the layout of the plan for the ventilation fans and air vents.

Through doing this project, we learned heat is transferred in three ways and how to minimize the heat in the classroom. We have come up with ways to counter the three ways of heat transfer. We also have better understood the concepts of heat transfer and in our project, we have use them to counter the heat in the classroom. For example, our ideas for convection. This project has help us to think about the countless ways of reducing heat without using an air-conditioner, which uses a lot of energy and is not environmentally-friendly.

While doing this project, we have encountered a few problems. An example is our busy holiday schedule. Since we can only meet on one day, we made the best of it by planning brainstormed as much ideas as we could. After that day, we met online using Skype and finished the rest of the project.
