I am trying to model the inverter AC which is a Veritable refrigerant flow system. To achieve this i have used following class objects Cooling coil: DX:VRF, HVAC Template: Terminal Unit : VRF, Air conditioner : VRF and a constant volume fan.
there is no outdoor air system.
What i suspect is that the problem may be with cooling capacity curves though i am not sure that my approach of modeling is currect (as i am a new user of energy plus) i have got the capacity table of the system and created the performance curves as per the help documentation. but i am confused about the cooling capacity curve function of flow fraction.
Hope i have elaborated my problem and will be able to get some help
