Manual design of air-conditioning systems
To define the air-conditioning systems manually in the program, you must enter terminal units for each zone (in the "Terminal units" section) and, if necessary, the associated centralised supply system (in the "Air conditioning systems" section).
The following links set out the procedure to follow in each case:
The following table shows the combinations of air-conditioning systems and terminal units that must be entered into the program to model different types of installation:
