Biography

• PhD in Mechanical Engineering, Sustainable Thermal Energy Technologies (2014), University of Warwick, UK.

‘Thermodynamic and heat transfer analysis of a carbon – ammonia adsorption heat pump’
Development of a novel adsorption heat pump cycle working with active carbon and ammonia. Includes the development of a numerical model of the novel cycle, improvement of the heat transfer characteristics of the solid sorption material, design and manufacturing of heat pump and final testing.

• MSc in Design of Rotating Machines (2010), Crafield University, UK.
• MEng in Industrial Engineering (2010), Universidad Politécnica de Valencia, Spain.

Research Interests

Since 2019 I have been working in the Programme Grant LoT-NETLink opens in a new window (Low Temperature Heat Recovery and Distribution Network Technologies).

My two main research areas are sorption heating and cooling technologies, and data analysis and modelling of energy systems.

Other areas of interes include:

• Absorption / Adsorption
• HVAC
• Heat driven heat pumps
• District heating networks
• Low temperature heat distribution networks
• Systems modelling and simulation
