As part of UK Public Sector Decarbonisation Scheme (PSDS), Derby College was awarded funds to carry out heat decarbonisation and energy efficiency measures including the replacement of the existing gas-fired boilers with heat pumps at Broomfield Hall Campus.
Trane UK supplied a high efficiency thermal system comprising 1 x Conquest CXAX air-cooled Heat pump and 1 x City RTSF water-to-water Heat pump.
This combination of Air Sourced and Water Sourced Heat Pumps installed in cascade configuration provides a renewable energy alternative to traditional gas fired boilers:
• 600kW of Heating
• Up to 80°C of leaving water temperature
• Low GWP refrigerant with low impact on the environment (R454B and R1234Ze)
This project represents a best practice example of Trane thermal systems that reduce operating costs and CO2 emissions while improving indoor air quality. The low-carbon heating solution installed at Broomfield Hall fully replaces the existing gas boilers. It will help Derby college achieve:
• 790,000 kWh annual energy savings
• 160 tons in CO2 annual emission reduction
• Total Efficiency Ratio (TER) improved by 400%.
The project recieved two recognitions:
• Highlighted in the UK government's decarbonization summary report of January 2022
• People's Choice Award at EHPA 2022 Forum.
