Variable Refrigerant Flow (VRF) system modeling includes describing both the outdoor condenser unit of the system as well as the indoor evaporator units at each of the zones. Each manufacturer places restrictions on how much indoor unit capacity can be coupled to a particular outdoor unit. EnergyPro will check how much indoor unit capacity has been specified and ensure that this falls within the acceptable limits of the VRF manufacturer.
You should review the VRF modeling guide at www.energysoft.com under the Support section of the website.
Verify the total capacity of each outdoor condenser unit that has been input at the System level of the building tree. Navigate to each Zone under that particular system, and verify the capacities of the indoor units that have been input at the Mechanical tab for the Zone. This total installed capacity of indoor units must fall within the parameters of the manufacturer.
