- A typical unit pairs a membrane energy recovery ventilation core with a desiccant regenerator. The air-side hardware follows standard AHU components: fans, filters, coils, and the membrane module.
- Less compressor lift → higher COP. Less reheat energy because the coil no longer overcools. Better control of supply RH independent of supply temperature.
- Building type Benefit Humid-climate offices Large latent load, strong fit Laboratories See laboratory heat recovery Dry climates Marginal — use sensible recovery For sizing the air handler around a membrane module, use the method in AHU selection calculation. Membrane AC is best viewed as an extension of total-energy recovery, not a replacement for it.
METROembrane air conditioning systems separate the sensible and latent cooling loads using a liquid-desiccant loop and a membrane contactor, rather than a single overcooling coil. The result is drier supply air at a higher coil evaporating temperature — which raises the chiller COP.
