The European Union regulates ventilation units through Regulation (EU) 1253/2014 (the “Ecodesign” Lot 21 measure). It sets binding minimum thermal efficiency and fan-power limits for units placed on the EU market, so any AHU or ERV sold in Europe must comply. Scope Applies to residential and non-residential ventilation units with a fan electric power of […]
ASHRAE 62.1 Ventilación y recuperación de energía
ASHRAE 62.1-2022 sets the minimum ventilation rates for acceptable indoor air quality, and its requirements directly drive how much outdoor air — and therefore how much recoverable energy — a system must handle. Energy recovery is the bridge between good ventilation and reasonable energy bills. The Ventilation Rate Procedure Section 6.2 uses the Ventilation Rate […]
Ventilacion con recuperacion de energia por membrana
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 […]
