Hi all,
I am modelling a building with 12 flats in it (existing building), with each flat having the following services:
- 1 central condensing gas boiler 88% seasonal efficiency
- hot water central heating system with radiators
- mechanical venilation with heat recovery, per flat, with dedicated MVHR units (Titon HQ1) in each flat, seasonal efficiency 80% (supply areas: sitting room, bedrooms; extract areas: bathrooms, kitchen)
Now I have been trying for months to model it in EnergyPlus following the example of (AirflowNetwork_MultiZone_SmallOffice_HeatRecoveryHXSL.idf) but with no luck..EnergyPlus comes really restrictive with how to build it..for some reason it should be a part of HVAC (or maybe I got that wrong), and I really struggled with getting around the fact that EnergyPlus requires supply and return nodes for every zone, when it is not the case of MVHR as it supply to different zones to the one that extract air from. Also there is no cooling or heating coils in my system, but apparently I cannot get away from energy plus without having them (as energyPlus won't accept uncontrolled unheated ducts)
Anyhow, I tried to attach a picture and attachment here..but since I am new I don't have enough points apparently. I would really appreciate any advice.
Thanks all
Alaa
