Optimising thermal store design for CHP
In his second instalment on modern CHP design, Remeha’s Ryan Kirkwood explores use of thermal stores and how this can maximise CHP efficiency
Unlocking the secrets of the black box: control strategies for engineers
Changes in controls can deliver big energy savings, but many shy away from tackling the BMS system, says Verco’s Tom Randall, who sets out his thoughts on control-strategy principles to help demystify the ‘black box’
Danish district heating – The heat of the moment
Copenhagen’s district heating relies largely on biomass and waste incineration power plants, but net-zero carbon targets are now encouraging suppliers to harness energy from renewables and industrial by-products. Alex Smith reports
Making the switch from gas-fired CHP to heat pump
Lower carbon factors for Grid electricity proposed for Part L are already in place in London. Andy Pearson looks at one scheme in North London where the design is switching from gas CHP to heat pump
Using water as a refrigerant in a commercial chiller
The eChiller is a novel solution that uses water as a refrigerant. Green Thermal Energy’s Garry Broadbent explains how it works and why it’s suitable for applications requiring chilled water flow temperatures of 16°C and above
