For temperature control, we chose the highest specification Fujitsu units available. These were selected for several reasons, namely their reliability and exceptionally quiet operation. They also use the latest R32 refrigerant, renowned for its energy efficiency and very low Global Warming Potential (GWP).
For mechanical heat recovery ventilation, we opted to use equipment from Daikin. We chose this because it offers the highest efficiency with regards to heat recovery. It also comes with built in monitoring devices to measure CO2 levels, adjusting the rate of extraction or supply accordingly.
The result was a safe and comfortable working environment for all radio station producers and presenters.
