First-of-its-kind system capable of simultaneous cooling and heating

Carrier is pleased to introduce its new Toshiba Carrier single-phase variable refrigerant flow (VRF) heat recovery system that will offer twinning capability to achieve greater capacity. This new VRF system is part of a larger introduction of Carrier commercial VRF products that offer greater installation flexibility, improved zoning control and enhanced efficiency. Carrier, a world leader in high-technology heating, air-conditioning and refrigeration solutions, is a part of UTC Climate, Controls & Security, a unit of United Technologies Corp. (NYSE: UTX).

The Toshiba Carrier single-phase VRF heat recovery system is the first of its kind in the heating and cooling industry to offer coupling ability to increase tonnage capability. Modules are available in 6- and 12-tons and can be combined to form larger systems. The 6-ton unit can be paired with up to 12 multiple style indoor units while the 12-ton outdoor unit can be matched with up to 25 multiple style indoor units.

The system is powered by a direct-drive, inverter-driven 64-step outdoor motor and features backup capability thanks to its multiple compressors.

“We are excited to see the results of our focus on research and development translate into another heating and cooling solution that promises to deliver greater flexibility and efficiency for our customers,” says Meredith Emmerich, managing director, Ductless & VRF Solutions, Carrier. “We’re seeing a massive demand increase for VRF technology that allows engineers and architects to provide climate control with greater flexibility, zoning options and energy efficiency. Carrier is pleased to respond with a powerful system that can deliver what customers expect from our trusted brand.”

The system comes equipped with up to 330 feet (100 m) of outdoor control wiring as well as 985 feet (300 m) of actual total system piping (liquid line). The operating temperature ranges from 14 degrees to 122 Fahrenheit for cooling and from -13 to 60 Fahrenheit in heating mode.

The modules boast two or three inverter-driven twin rotary compressors and backup capability due to multiple compressors.

“We continue to invest and innovate to ensure Carrier VRF products remain at the forefront of this accelerating trend in heating and cooling,” Emmerich says. “Carrier recognizes the value of providing the most efficient and flexible VRF solutions and is poised to deliver products and services that set the standard in the industry.”
