YORK has passed and exceeded the laboratory testing phase of the US Department of Energy (DOE) Commercial Building HVAC Technology Challenge for its rooftop unit (RTU).
YORK developed an innovative, all-electric 15-tonne heat pump, which allows for simultaneous compressor and electric heating to provide comfortable performance down to -10F while also minimising the use of electric resistance heating.
As a result, it helps to improve efficiency and support decarbonisation benefits.
This innovative unit utilizes a new platform that allows it to be used in both replacement and new installation applications.
Its well-established controls system allows the RTU to interface with a wide variety of Building Automation Systems (BAS), which contributes to application flexibility.
This includes demand response capabilities to limit electric heat run time via remote access. This unit was developed from the Choice rooftop platform.
The full range of Choice RTUs is designed to fit about 70 per cent of the competitive installed base, minimizing the need for costly transition curbs.
The Choice platform offers options that cover the full range of efficiency levels, from basic models to those that qualify for rebates. In addition, a direct drive supply fan makes the unit more efficient by removing belt losses. It also improves serviceability, giving contractors better access to the fan and making it easier to adjust the fan speed to match project needs.
Bosch Home Comfort Group global deputy CEO and president Americas, David Budzinski, said the DOE Commercial Building HVAC Technology Challenge has allowed Bosch Home Comfort Group to showcase its expanded engineering capabilities to support their strategic objective of innovation, efficiency and decarbonisation.
YORK products are manufactured in Norman, Oklahoma, and as a continuation of this challenge, the YORK RTU will be installed in a field trial later this year to assess real-world performance in extreme cold climates.
