VRV & VRF Airconditioning systems

10/08/2010 2:46 AM

How the controlling is done in vrv & vrf systems. How do the fresh air requirements are taken care off. Can we have heating and cooling from the same system.

<...heating...from the same system...>

Yes, though it wouldn't be an "air conditioning" system in that mode, as nothing is being done to alter the humidity of the product air.

I think you are asking of the much bandied subject of indoor air quality, and how it relates to the HVAC ventilation.

Aside from purely prescriptive solutions, for instance basing ventilation rates on CFM per room or CFM per person, CO2 monitors in return ducts are apparently proving to be adequate in meeting air quality standards in performance-based ventilation systems.
