Ammonia heat pump capturing river water wins EHPA award
The 5.2 MW project in Scotland received the 2021 City of the Year award from the European Heat Pump Association.
The European Heat Pumps Association (EHPA) named West Dunbartonshire, Scotland, The Council, Vital Energi and Star Renewable Energy (a division of Star Refrigeration) as the recipient of the 2021 City of the Year award for their Collaboration on a river source ammonia / NH3 (R717) heat pump project in Glasgow, Scotland.
The annual EHPA Heat Pump Awards recognize the “most efficient, smart and sustainable heat pump projects” across Europe. The awards were launched in 2011.
“This is a huge achievement, and I would like to warmly congratulate the team for achieving this recognition, which shows that we are really leading the way,” said Councilor Iain McLaren, Chair of the Infrastructure Committee. , regeneration and economic development from West Dunbartonshire Council. .
“This system is the first of its kind in Scotland, and I am proud that West Dunbartonshire is using this natural resource to provide energy, not only to help us meet our net zero goals, but also to support residents and help to eliminate fuel poverty. . “
District heating network
The project is a 5.2 MW (1479 TR) ammonia source heat pump solution for a district heating network serving the development of Queens Quay in Clydebank, west of Glasgow. It is the first industrial-scale river heat pump for this purpose in the country, according to Star Refrigeration.
The system consists of two independent heat pumps, each with a capacity of up to 2.6 MW (739TR), and two 900 kW drive motors. The system has a coefficient of performance (COP) of up to 3.34 at full load and 3.07 at two-thirds load, according to Dave Pearson, sustainability director of Star Refrigeration Group, who spoke about the project during the Institute of Refrigeration conference in April.
The heat pumps produce water up to 80 ° C (176 ° F) for the 2.5 km (8,202 ft) pipe network, connected to residential and commercial buildings. The district heating network includes the town hall, a college and more than 1,000 homes.
“Water source heat pumps have been in use in mainland Europe for several years, but the Queen’s Quay project is the UK’s first large-scale, high-temperature heat pump deployment,” Pearson explained.
“We are delighted that the Queen’s Quay heat pump project has been recognized as a leader in the provision of low carbon district heating,” he added.
Star Refrigeration sees great potential for water heat pump deployment in various locations across the UK “In England alone it is estimated that over 6 GW of renewable heat can be extracted from rivers and canals. The long coastline of Wales and Scotland also offers potential for heat pumps to extract more heat from the sea. ”
Star doesn’t just focus on helping customers use renewable energy sources; he also wants to help them save energy. The company recently launched SEC Calculator, a benchmarking application that allows temperature-controlled storage companies to compare their site’s energy performance with industry best practices and predict their potential energy and cost savings.
