Looking at the HVAC in the documentation, it seems that all ventilation systems must either be linked to a heating or cooling system, or have no heat recovery at all.
No, you can model AirLoops with heat recovery and without cooling/heating coils. Please try it.
If your system has supply/exhaust fans and heat recovery in each zone, ZoneHVAC:EnergyRecoveryVentilator is another option, which does not require AirLoops.
