Lennox is the First HVAC OEM to Complete the U.S. Department of Energy's Commercial Building HVAC Technology Challenge Lab Validation
Lennox (NYSE: LII) has achieved a significant milestone as the first manufacturer to complete laboratory validation for its commercial cold climate heat pump rooftop unit (RTU) in the 15-25 tons category of the U.S. Department of Energy's Commercial Building HVAC Technology Challenge.
The innovative heat pump technology, developed at Lennox's Texas Product Development and Research laboratory, addresses cold climate performance challenges and defrost limitations. The solution is particularly important as commercial building space conditioning accounts for approximately 40% of commercial energy use in the United States.
The prototype will undergo further validation through installation in a U.S. commercial building to test performance in severe winter conditions. This achievement follows Lennox's previous success in the DOE's Residential HVAC Challenge, where it was also first to complete Phase 1 testing in 2022.
Lennox (NYSE: LII) ha raggiunto un traguardo importante: è il primo produttore ad aver completato la validazione di laboratorio per la sua unità rooftop (RTU) a pompa di calore per climi freddi nella categoria da 15 a 25 tonnellate, nell'ambito del Commercial Building HVAC Technology Challenge del Dipartimento dell'Energia degli Stati Uniti.
La tecnologia innovativa, sviluppata nel laboratorio di Product Development and Research del Texas, affronta le difficoltà di funzionamento in climi freddi e i limiti delle procedure di scongelamento. La soluzione è rilevante perché la climatizzazione degli edifici commerciali rappresenta circa il 40% dei consumi energetici commerciali negli Stati Uniti.
Il prototipo sarà ulteriormente convalidato mediante l'installazione in un edificio commerciale negli USA per verificare le prestazioni in inverni rigidi. Questo risultato segue il precedente successo di Lennox nella Residential HVAC Challenge del DOE, dove era stato il primo a completare la Fase 1 nel 2022.

텍사스 제품 개발 및 연구소에서 개발한 이 혁신적 히트펌프 기술은 저온 성능 문제와 제상(defrost) 한계를 해결합니다. 이 솔루션은 상업용 건물의 공간 냉난방이 미국 내 상업용 에너지 소비의 약 40%를 차지한다는 점에서 특히 의미가 큽니다.
프로토타입은 혹한기 환경에서의 성능을 검증하기 위해 미국 내 상업용 건물에 설치되어 추가 검증을 거칠 예정입니다. 이번 성과는 Lennox가 2022년 DOE의 주거용(Residential) HVAC 챌린지에서도 1단계(Phase 1) 테스트를 가장 먼저 완료했던 이전 성공을 잇는 것입니다.
Lennox (NYSE: LII) a franchi une étape importante en devenant le premier fabricant à achever la validation en laboratoire de son unité rooftop (RTU) à pompe à chaleur pour climats froids dans la catégorie 15–25 tonnes du Commercial Building HVAC Technology Challenge du Département de l'Énergie américain.
La technologie innovante, mise au point dans le laboratoire de Product Development and Research de Lennox au Texas, répond aux problèmes de performance par grand froid et aux limites des cycles de dégivrage. Cette solution est d'autant plus importante que la climatisation des bâtiments commerciaux représente environ 40 % de la consommation énergétique commerciale aux États-Unis.
Le prototype fera l'objet d'une validation complémentaire par une installation dans un bâtiment commercial américain afin d'évaluer ses performances en conditions hivernales sévères. Cette réussite s'inscrit dans la continuité du précédent succès de Lennox dans la Residential HVAC Challenge du DOE, où il avait également été le premier à achever la phase 1 en 2022.
Lennox (NYSE: LII) hat einen wichtigen Meilenstein erreicht: Als erster Hersteller hat das Unternehmen die Laborvalidierung seiner Rooftop-Einheit (RTU) mit Wärmepumpe für kalte Klimazonen in der 15–25-Tonnen-Klasse im Rahmen der Commercial Building HVAC Technology Challenge des US-Energieministeriums abgeschlossen.
Die innovative Wärmepumpentechnik, entwickelt im Product Development and Research Laboratory von Lennox in Texas, begegnet Leistungsproblemen bei Kälte sowie Begrenzungen beim Abtauen. Die Lösung ist besonders bedeutsam, weil die Raumklimatisierung gewerblicher Gebäude in den USA etwa 40 % des gewerblichen Energieverbrauchs ausmacht.
Der Prototyp wird nun weiter validiert, indem er in einem US-Gewerbegebäude installiert und unter harten Winterbedingungen getestet wird. Dieser Erfolg folgt auf Lennox’ frühere Leistung in der DOE Residential HVAC Challenge, bei der das Unternehmen 2022 ebenfalls als erstes die Phase 1 abgeschlossen hatte.
