Absorption chiller teams up with CHP system at University of East Anglia
Using waste heat from the University of East Anglia’s CHP system, this absorption chiller will supply 1000 kW of chilled water during the summer and mid-season periods of the year.
An absorption chiller supplied by McQuay UK for a project at the University of East Anglia (UAE) utilises waste heat from the university’s CHP system during the summer and mid-season periods to produce up to 1000 kW of chilled water without using harmful refrigerants. Prior to the installation of this Thermax chiller, cooling at the university had been achieved on a piecemeal basis with five packaged chillers and a large number of separate split units. Following a study by consultant Integrated Energy Utilities, a strategy has been developed to use heat from the CHP system. This strategy called for a £1 million centralised system for generating and distributing chilled water. The absorption chiller is driven by hot water from the CHP system. Chilled water is delivered at 6°C and returns at 12°C. Mel Pascoe, energy manager at UAE, says, ‘The tender process established that the McQuay package for the chiller, craneage and installation gave us the best value for money at a time when spending on capital equipment in higher education is under pressure.’
