Trane – by Trane Technologies, introduced the completion of its redesign of the Precedent Rooftop Unit portfolio, and updates to well-known unitary, split systems and variable air volume products. Two new indoor unit styles have also been added to the Trane/Mitsubishi Electric HVRF product line, an all-electric variable refrigerant flow (VRF).
“Decarbonization is easier when HVAC equipment is easy to install, easy to use, and easy to operate with low global warming potential refrigerants,” said Oakley Roberts, vice president of product management at Trane. “Trane is making it easier for building owners, engineers and contractors to help make headway in all these areas with additions to the market-first, all-electric HVRF, more rooftops and split systems that are equipped with low-GWP refrigerants and the completion of the next-generation Precedent line that help consistently deliver on expectations.”
Trane has added two families of indoor units to the line of Trane/Mitsubishi Electric HVRF, the only all-electric hybrid VRF unit available on the market. The HVRF system uses a combination of refrigerant to connect outdoor units to the Hybrid Branch Controller (HBC) and water to connect the HBC to indoor units. This unique two-pipe system combines the advantages of VRF and hydronic chillers into an all-electric heat pump that can heat and cool simultaneously while reducing refrigerants in the overall system.
Ceiling cassettes and wall-mounted options have been added to the existing ceiling-concealed indoor units, helping to enhance flexibility and accommodating various space designs and esthetics. The system delivers zoned comfort, helping owners of multi-zone commercial buildings that require individual temperature settings achieve sustainability goals through electrification while complying with ASHRAE 15 2022 refrigerant requirements.
Contractors working on retrofits or new hotels, dormitories, multi-family complexes, senior living facilities, offices, and hospitals will enjoy the advantages of VRF while helping to manage life cycle costs and system efficiency provided by this system.
Trane has also finished updating the next-generation Precedent portfolio. Features and available options are uniform across the entire Precedent portfolio and all units ship with low-GWP R-454B refrigerant to help small commercial offices, restaurants, schools, warehouses and government buildings operate more sustainably.
Precedent units come in a full range of capacities from three to 25 tons, efficiency ratings including standard, high and ultra-high eFlex, and heating types including gas/electric, electric/electric, heat pump and hybrid dual fuel.
