Swimming pools Pool halls exhaust warm, moisture-laden air constantly. Without recovery, that latent heat is lost. An enthalpic rotary wheel or membrane plate unit recovers both temperature and humidity, slashing pool heating and dehumidification bills 40-60%. Gyms and fitness centers High occupancy means high fresh-air demand and high moisture. Sensible plate recovery handles the heating-season […]
Recuperación en laboratorio : capturar energía de escape de campanas de gases
The separation rule Laboratories are energy hogs – fume hoods run at high face velocities and dump conditioned air outdoors continuously. A lab can use 5-10x the energy per square meter of a typical office. Recovering that exhaust energy is one of the fastest paybacks available. Fume hood exhaust may carry chemical vapors, so supply […]
Cogeneración (CHP) : la cogeneración encuentra la recuperación de calor
What CHP does Combined Heat and Power (CHP), or cogeneration, produces electricity and useful heat from a single fuel source. Instead of venting engine or turbine exhaust and jacket heat, a CHP plant captures it for space heating, process steam, or domestic hot water – lifting total fuel efficiency from ~40% (grid power alone) to […]
Recuperación HVAC en sala limpia : calidad de aire sin energía desperdiciada
The contamination barrier Cleanrooms demand exceptionally high air-change rates – often 20 to 60 air changes per hour – to maintain ISO particle classes. That airflow represents a massive energy stream leaving the facility fully conditioned. Recovering it is essential, but cleanrooms add a hard constraint: supply and exhaust air must never mix. Because cross-contamination […]
Supermarket Heat Recovery: Refrigeration + Ventilation
Two loads, one building Supermarkets and big-box retail bleed energy in two ways: refrigeration rejects heat constantly, while fresh-air ventilation (bakery, deli, entrances) demands conditioning. Heat recovery bridges them. Ventilation recovery Exhaust from the sales floor is warm and can pre-heat incoming make-up air in winter via a rotary wheel or plate exchanger. In cooling […]
Hospital Heat Recovery Without Losing Air Quality
Why hospitals recover heat Hospitals run 24/7 with very high fresh-air rates – operating theatres, isolation rooms, and wards all demand conditioned outdoor air. Ventilation can be 30-50% of a hospital’s energy bill. Air-to-air recovery cuts that load sharply, but infection control sets a hard rule: supply and exhaust must never mix. The safe choice: […]
Recuperacion de calor en procesamiento de alimentos: capturar calor de proceso y de extraccion
A heat-rich sector Food plants bake, cook, pasteurize, and chill around the clock. Both the process air and the building exhaust carry large amounts of recoverable energy – often with moisture, grease, or particulates that demand a cleanable, robust exchanger. Technology fit Enthalpic plate or rotary wheels recover both heat and moisture from humid exhaust […]
California Title 24 Heat Recovery
California Title 24, Part 6 (the Building Energy Efficiency Standards) is the most aggressive state energy code in the U.S., and its 2022 edition — effective 1 January 2023, with a July 2024 Supplement — puts heat recovery at the center of both nonresidential and multifamily compliance. This article distills the recovery provisions that trigger […]
Recuperacion de calor de fuente aguas residuales: reutilizacion de la energia del agua de drenaje
The hidden reservoir Showers, wash-down, and process drains leave buildings at 25-40C – warm enough to be a valuable heat source. Wastewater (drain-water) heat recovery captures it before it disappears down the sewer. How it works Drain-water heat exchangers wrap a coil around or sit inside the greywater stream, pre-warming incoming cold water. Heat pumps […]
Passive House Heat Recovery
The Passive House (Passivhaus) standard — from the Passive House Institute (PHI) in Darmstadt — is the most demanding envelope-and-services benchmark in buildings, and continuous ventilation with heat recovery is mandatory. This article covers the recovery requirements and how they compare with code minimums. Core Recovery Requirement Metric PHI limit Sensible heat recovery efficiency (HRV/ERV) […]
