Choosing between an enthalpy recovery wheel and a membrane exchanger comes down to contamination risk, maintenance tolerance, and how much latent recovery you need. This comparison distills the trade-offs. Side-by-Side Factor Enthalpy Wheel Membrane Moving parts Yes (motor, seals) No Air cross-contamination Small (seal leakage) None (separate streams) Latent effectiveness 70–85% 60–80% Frost risk (cold […]
Membrane Air Conditioning Systems
Membrane 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. Core Components A typical unit pairs a membrane energy recovery ventilation core […]
Membrane Energy Recovery Ventilation
Membrane energy recovery ventilation (MERV) uses a stationary, non-rotating polymer membrane core to transfer both sensible and latent heat between supply and exhaust airstreams. Unlike a rotating energy recovery wheel, a membrane exchanger has no moving parts and physically separates the two airstreams, which eliminates the carryover of moisture, odors, and particulates that can occur […]
