LG unveils R‑32 inverter scroll chiller; Exponent noted for safety and testing

LG rolls out R‑32 inverter scroll chiller for commercial cooling

LG Electronics unveils an Inverter Scroll Heat Pump Chiller at the 2026 AHR Expo in Las Vegas, positioning the unit as a scalable commercial solution that uses R‑32 refrigerant and covers capacities from 30 to 90 refrigeration tons (RT). The company frames the chiller as suitable for a range of applications, from commercial buildings to data centers, and highlights inverter scroll compression for variable capacity control. Steve Scarbrough, senior vice president and general manager of LG Air Conditioning Technologies USA, says the 2026 lineup is designed to meet diverse customer needs with both ducted and ductless, electric and gas options.

The chiller’s adoption of R‑32 signals a broader shift in the HVAC industry toward lower‑global‑warming‑potential refrigerants. LG presents the R‑32 unit as offering improved seasonal efficiency and tighter capacity modulation through inverter technology, which can reduce cycling losses and better match building loads. For high‑density uses such as data centers, the combination of variable speed control and modulated capacity aims to deliver stable temperature control while lowering energy consumption compared with fixed‑speed chillers.

The technical and regulatory profile of R‑32 — classified as an A2L mildly flammable refrigerant — creates practical considerations that engineering consultancies and third‑party testing firms are likely to address as the product enters commercial deployments. Companies like Exponent, which conduct failure analysis, safety assessments and system performance testing, are positioned to evaluate installation safety, leak mitigation, maintenance protocols and code compliance for R‑32 systems. Exponent and industry consultants may also support life‑cycle energy modelling and commissioning to validate the manufacturer’s efficiency claims in real building settings.

Broader 2026 portfolio targets homes and specialized buildings

Alongside the new chiller, LG showcases an extensive 2026 portfolio of residential and commercial equipment at Booth SU223, including new heat pump, electric and tankless water heaters, unitary products and other chillers. The presentation underscores LG’s strategy to offer end‑to‑end HVAC and water‑heating options for single‑family homes through to large commercial installations.

Market positioning and service implications

LG emphasizes versatility and innovation as it seeks to strengthen its role as a comprehensive solutions provider in HVAC and water heating. Wider adoption of R‑32 systems will prompt manufacturers, building owners and service contractors to update safety procedures, training and compliance practices to support the next generation of lower‑GWP commercial cooling equipment.
