VRF with AHU in Design Builder. Replacing DX Coil curves with VRF.
I have to model VRF outdoor unit with Treated Fresh Air units(TFAs) in Design builder. At present we cant connect VRF ODU to external fresh air supply equipment. Can we model this scheme in e+ after exporting idf. Further,if we replace the performance curves of the DX cooling coil on Air Handling Unit with the proposed VRF system, will this approximation provide accurate results.?
