How to model,2 FCU (for Heating) and DX unit (Cooling)

1 post / 0 new


I have a project (for an elementary school) that has classrooms designed for HVAC in following manner;

1. Heating is provided by natural gas hot water boiler with the help of individual 2 fan coil unit/unit ventilator in each classroom

2. Cooling is provided by each individual dx unit for each classroom.

In order to model the above combination in the DD mode of e QUEST, I chose DX coils (for each zone) and hot water loop for multiple zones(since there is one single boiler that serves to the entire school)

Is this a correct way to define this system?
