Toshiba VRF awarded central role
25th August 2019
UK: Toshiba VRF air conditioning is providing high-efficiency cooling and heating for No 1 Great Central Square, part of a £50m regeneration scheme in the heart of Leicester.
The four-and-half-acre development, being built by Morgan Sindall Construction, includes two new hotels, premium commercial offices and a new public area – Great Central Square – in Leicester’s city centre. No 1 Great Central Square comprises 35,000ft2 of open-plan office space over five floors, air conditioned by Toshiba’s SMMS-e system, installed by Ambivent Ltd.
Ten Toshiba outdoor units supply cooling and heating via 40 indoor cassettes installed across the building, with a heat recovery ventilation system in each wing. A 12kW Toshiba split system running on R32 refrigerant installed in the reception area completes the total building system. High level control and monitoring is provided by Toshiba’s Black Pear HVAC controller.
“The project was originally specified with ducted equipment from another manufacturer, however this was outside the budget,” said Joshua Medhurst, who carried out the mechanical services design under the supervision of Ambivent’s design manager Steve Thornton. “We proposed an alternative system using Toshiba’s SMMS-e two-pipe VRF with cassettes, as it met the requirements for high quality, reliability and delivery of both heating and cooling with excellent energy efficiency. It won the day.”
