Your task is to devise a system that is able to accomplish the desired cooling requirements.

The project can be divided into several steps:

1- Load estimation (lights, people, equipment, transmission through walls and roof...):

discuss variation throughout the day and critical months of the year

2- Quantity and state of cooling air to be distributed through the main duct.

3- Duct and fan (optional) Sizing

4- Refrigeration System Design: this system uses refrigerant (R290) as the working fluid

and could be a simple vapour compression cycle. The main constraint about this system

is that it has to provide the cooling load calculated in part 1 but for 10 classrooms

located on one floor of the school.

Take assumptions when necessary and clearly state and justify taken assumptions in

any of the design stages.
