How does ventilation (the V in HVAC) work for FCUs? If the pipes only bring coolant to each unit where does fresh air come from? Conventional HVAC systems have Heat Recovery Ventilation so what's the equivalent here?

I don't know. I don't think that most Asian apartments have central fresh air. Usually the unit owners open windows regularly.

But opening the windows would negate most of the benefits of the higher efficiency of the FCU, would it not?
