[Equest-users] 4 Pipe FCU- Refrigerant lines (supply and return) instead of CHW lines

[Jayant Patil]

Hi,

I am looking to model a custom built up unit ventilator for classroom
building. The UV in classroom is basically a 4 pipe FCU system. The HW is
supplied by natural gas boiler. Instead of CHW water lines, an outdoor
split system (air condenser)  is utilized to run the refrigerant (supply
and return)lines to the UV.

In e-quest, if FC is used as system type, a CHW loop is required (which is
not present in this case). Therefore, for a custom system like this, is it
safe to model the air side system as "residential split unit" and HW loop
for the heating side? Since the cooling is provided by a split system,
I thought a RESYS2 system will be ok?

Has anybody encountered such type of system before to model in e -quest?

Thanks
