TKAC Working in Partnership with Mitsubishi Electric

Turn Key Air Conditioning regularly work in partnership with architects, designers, planning departments and regulators to create the best possible solution for the customer and the end user.

An excellent example of TKAC successfully working as part of a team is the creation of a heating system for Woolley Wood Primary School in Sheffield.

Woolley Wood School, Sheffield

Woolley Wood School

Woolley Wood is a primary community special school for boys and girls with severe and complex learning difficulties and disabilities.

When the old school building, built in 1934, was deemed unsuitable for purpose, Sheffield’s local education authority called on Kier Sheffield LLP to oversee the design & construction of the new school. Within the brief was the requirement to meet the city council’s strict planning regulations which call for a minimum of 10% of the building’s energy needs to be met from renewable or low carbon energy as well as a 20% reduction in carbon emissions.

Yorkshire-based Mechanical & Engineering Consultants, Thornley & Lumb Partnership Ltd was commissioned to design and specify building services.

TKAC – Renewable Heating for Sheffield School

There were a number of specific challenges to the Sheffield School project.

  • The only power energy supply to the property was electricity.
  • The new system had to provide heat for the whole school including hot water for a hydrotherapy pool.
  • Plant space was severely restricted.
  • Access to the school site was restricted making on-site construction impossible.
  • There is an on-going requirement for energy efficiency targets for the new building to be monitored.

With so many technical, logistical and financial limitations on the project, Thornley & Lumb approached Turn Key Air Conditioning for our expertise and our experience in rising to such challenges.

Mitsubishi Ecodan CAHV Air Sourced Heat Pumps

The Ecodan CAHV is a unique solution to providing renewable heating to public buildings. The monobloc air source heat pumps were ideal to serve the underfloor heating system designed for the school. Underfloor heating eliminates the need for wall mounted radiators, saves space, and provides heat and hot water for the entire school.

Air source heat pumps are classified as renewable energy technology by the EU and the UK Government for the simple reason that for every 1kW of energy consumed an average of 3.2kW of usable heating energy is produced. Air source heat pumps operate effectively in ambient temperatures as low as -25°C, producing hot water of up to 70°C. Each Ecodan CAHV unit is capable of producing up to 43kW of energy and can work in combination to produce as much energy as is required.

Mitsubishi Electric's Ecodan

The new heating and hot water system uses six Mitsubishi Electric Ecodan® CAHV-P500YA-HPB monobloc air source heat pump boilers.
