Professor Bob Critoph
Link opens in a new window
Bob's research concentrates on sorption systems that can be used for heat driven heat pumps – for example a gas-fired heat pump with significantly less consumption than a gas boiler. Other sorption applications include heat transformers that can upgrade industrial waste heat to higher temperatures and thermochemical heat stores.
Bob is director of Lot-NET, a six-year interdisciplinary collaboration researching the integration of low temperature networks with heat pump and thermal storage technologies to maximise waste and ambient heat utilisation in low or zero-carbon solutions. Bob is also Principle Investigator on several other projects including 4S-DHW, a project investigating how domestic hot water can be provided using low carbon heat pump technology, and BEIS Adsorption Heat Pump, a government funded project to develop the next generation of common domestic gas boilers.
Dr Stan Shire
Stan is a Reader (Research and Teaching) of Sustainable Energy Systems in the School's Mechanical and Process Engineering stream. His research is focused around solar energy, energy storage, phase change materials, waste heat recovery, thermochemical storage and upgrading of thermal energy and thermally driven cooling technology.
Work on Solar Energy, Thermal Systems and Energy Storage is central to much of the research carried out within the University of Warwick's Global Research Priority (GRP) on Energy, for which Stan is the academic theme lead in Thermal Energy and Solar Energy Research Themes. He is also a Co-Investigator on LoT-NET.
Dr Zac Tamainot-Telto
Zac is Associate Professor (Research and Teaching) of Refrigeration, Heat Pump and Energy Conservation. He was previously trained in France at University of Nancy I and National Institute of Applied Sciences, where he completed his PhD. His early research work was on the development of cost effective variable cooling load of conventional air conditioning systems in partnership with EDF.
He has contributed to modelling, designing, building and testing successful proof of concept prototypes. His previous projects include a 5 kW chiller using waste exhaust heat of a gas fired co-generator, a 2 kW cooling air conditioning unit for the Fiat Stilo car using waste heat from engine coolant and a 2 kW cooling solar driven mobile container for food storage in the desert. He has also been involved in industrial projects for development of compact Ammonia storage modules for NOx conversion through Selective Catalytic Reduction (SCR) in automotive and public funded project for development of Smart Hybrid Refrigeration Systems.
Dr Steve Metcalf
Steve is an Assistant Professor (Research and Teaching) in Sustainable Thermal Energy Technologies. He obtained his MEng and PhD in mechanical engineering from Warwick in 2004 and 2009, respectively. His PhD topic was on gas heat pumps and he has since worked on several EPSRC, EU, BEIS and industry funded research projects. Steve is Co-Research Investigator on Lot-NET and was the senior researcher on BEIS Adsorption Heat Pump.
His research interests include thermally driven heat pumps and refrigeration, heat storage and low-temperature heat networks.
Dr Angeles Rivero-Pacho
Ángeles is an Assistant Professor (Teaching-focussed) and manages the Electromechanical Engineering Degree Apprenticeship (EMDA) course. She completed her PhD in Mechanical Engineering within the STET group in 2014, developing a novel adsorption heat pump cycle working with active carbon and ammonia. She has previously been a Project Manager of the LoT-NETLink opens in a new windowLink opens in a new window project.
Her two main research areas are sorption heating and cooling technologies, and data analysis and modelling of energy systems.
Research Staff
Dr Roger Moss
Roger is a Senior Research Fellow. He read Engineering at Cambridge, then worked in turbine R&D at Rolls-Royce Derby. His DPhil (Osney Laboratory, Oxford) measured the turbulence spectrum from gas turbine combustors; afterwards he studied unsteady flows over turbine blades. After 14 years’ association with RR, he moved to Newcastle (Marine Engineering), re-vitalising their thermo-fluids teaching before returning to the Cotswolds, 4 years later, for family reasons. He joined the Warwick STET group in 2013, developing evacuated flat plate solar thermal collectors with Dr Stan Shire.For the past 4 years he has focused on ammonia/salt sorption reactions and their performance in resorption heat pumps.
Dr Sai Yagnamurthy
Sai is a Research Fellow at the University of Warwick, currently working on the project 'Heat Pumps Fully Integrated with Thermochemical Storages (HP-FITS). He obtained his PhD degree from IIT Delhi, India, where he worked on the topic "Adsorbents and strategies for higher performance adsorption cooling systems". He has also worked in collaboration with the University of Trento and the Kyushu University, on research projects related to polygeneration and adsorbent composite synthesis.His research interests include sorption based technologies for heating/cooling, thermal storage, desalination, etc.,
along with building energy efficiency measures.
