Re: [EnergyPlus_Support] VRF water-cooled condensers.



i used you advice to build the model, but when running this warning is showed:

   ** Warning ** AirConditioner:VariableRefrigerantFlow "VRF EXTERIORUNIT01 PBYP1".
   **   ~~~   ** ...InitVRF: VRF Heat Pump Min/Max Outdoor Temperature in Heating Mode Limits have been exceeded and VRF system is disabled.
   **   ~~~   ** ... Outdoor Dry-Bulb Temperature                 = 35.077
   **   ~~~   ** ... Heating Minimum Outdoor Dry-Bulb Temperature = -20.000
   **   ~~~   ** ... Heating Maximum Outdoor Dry-Bulb Temperature = 35.000
   **   ~~~   ** ... Check VRF Heat Pump Min/Max Outdoor Temperature in Heating Mode limits.
   **   ~~~   **  During Warmup, Environment=BARCELONA INVIERNO, at Simulation time=01/01 19:00 - 19:15

Anyone kown how i can solve it? Which is the Heating Min/Max Outdoor Dry-Bulb Temperature infuence in the VFR water condenser?

thanks

Yes, use a single plant loop to serve the VRF condenser.
Here's a file I have been playing with.
The imf file is the building and VRF system.
The idf is the plant loop.
The in.idf file is these two files after EPMacro assembles them together.

Dear all,

I am trying to simulate a VRF water condenser. I know that you can do it with version 7.2. In proyect, the water temperature is defined between 35ºC and 20ºC, so, I should include a boiler in the condenser loop.

Is this configuration possible today in energyplus? Anyone know how i can simulate it?

Thanks in advance
