Hybrid Dessicant Cooling Systems

Wow – Trane (soon to be IR) has a combo dessicant wheel/chiller system which seems to work backwards.  The device takes water from air just before it enters living space and dumps it back into air coming from outdoors.  I buy the concept – question is, why don’t we see this installed out there?  Money?  Performance? Maintenance?  Ignorance?   mrm

  1. It only works best if you need to reach humidity conditions of around 40%. For 0% RH; its best to use conventional desiccant wheels …whereas for humidity requirements of over 40% (taking into account the cost of providing regeneration heat) – it is best to use the HVAC cooling – reheating system. Trane’s system is a big hit in hospital operating rooms where there is a need for specific humidity levels without going down to 0% RH.
