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 […]
실험실 열회수: 배기 후드 배기 에너지 포집
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 […]
열병합발전(CHP): 코제너레이션과 열회수의 만남
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 […]
클린룸 HVAC 열회수: 낭비 없는 공기 품질
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 […]
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: […]
식품 가공 열회수: 공정열과 배기열 포집
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 […]
하수 열원 열회수: 배수 에너지 재사용
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 […]
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 […]
건축법 열회수 의무
Across jurisdictions, building codes increasingly mandate energy recovery once a system serves enough outdoor air. This overview compares the main regimes so a designer can specify one core that clears them all. Minimum Effectiveness by Regime Regime Trigger Minimum recovery ASHRAE 90.1-2022 (US) ≥ 5,000 CFM and ≥ 70% OA 50% enthalpy (AHRI 1060) IECC […]
