Examples of Research projects:
1) Low temperature community heat networks (LTHN)
Decarbonising the heat sector is central to many countries' energy policy agenda in mitigating climate change and working towards a carbon neutral society. The aim of the work is to identify the optimum supply and return temperatures to operate DH networks and heating systems in buildings. An alternative methodology was developed to investigate and plan the implementation of low temperature district heating (LTDH) in existing buildings with traditional high temperature radiators.
2) Regenerative Evaporative Cooling
Energy consumption for thermal comfort in buildings in hot and dry climates make up to 50% (rising to 70% in typical mid-afternoon) of total demand for power. This market is traditionally served by vapour compression systems, which are energy intensive and the energy performance affected by elevated ambient temperatures. Inevitably, at peak load demand, electricity grids reliability is affected, putting strenuous financial strains to increase power generation spare capacity. In addition, conventional air conditioning systems contribute directly and indirectly to emission of global warming causing greenhouse gases and carry health risks such as allergies and asthma for building occupants
The aim of this study is to develop a new configuration of heat pipe based indirect evaporative cooling system. The basic mechanical design is centred on the regenerative configuration of IEC system which integrates porous ceramic tubes as wetting media materials and tubular heat pipes in a compact modular heat and mass transfer exchanger (HPHMX).
Both experimental and theoretical results show that the system can be an energy efficient alternative for traditional vapour compression systems. an overall coefficient of performance of (COP) of 6-17 was achieved while water consumption rate reduced.
3) Solid desiccant air dehumidification
Thermal comfort in buildings is greatly affected with air relative humidity. In conventional vapour compression air conditioning systems, air moisture content is reduced through the process of air dehumidification by cooling it below its saturation temperature before reheating it, an energy intensive strategy.
the aim of this work is to develop a novel and compact design of an air dehumidification system. the system uses enhanced heat and mass transfer processes by limiting the heat of adsorption during the adsorption cycle. A mathematical model for complex heat and mass transfer processes have been developed and validated experimentally.
4) Low Temperature FPSE for power generation / water pumping in remote locations of developing countries.
Approximately 1.6 billion people worldwide do not have access to electricity [World Bank]. Most of them live in rural regions in developing countries which lacked access to grid electricity.
Grid extension programmes, though expensive, and the use of solar home systems have helped to bring the number of people without access to electricity down significantly. this project uses a FPSE that converts solar energy into mechanical power to drive an electric generator for power generation or a water pump for irrigation. The research project involved design, modeling and testing a prototype units under controlled solar radiation conditions.
5) Solar energy driven air conditioning
It is not a coincidence that space cooling in buildings using high energy consumption air conditioning systems are particularly widespread in countries with equally high solar energy resources. developing novel processes to enable space cooling in buildings using solar energy will address many challenges related to thermal comfort, power generation infrastructure, health and wellbeing of building occupants, etc. the research is on-going and aims to develop a low carbon cooling system.
Some of the most challenging issues facing the the built environment is reducing energy consumption in buildings particularly for the provision of space heat and cooling energy. As building standards of thermal buildings envelope become more stringent for new and refurbished buildings, current practices of high temperature heating systems may require a complete rethink, particularly in densely populated cities.
- Research focus: A multi-vector energy systems could integrate low temperature heat sources (e.g., renewable sources and waste heat from industrial processes), thermal storage (e.g., damping excess renewable power) and battery storage in the form of heat and power networks linking and creating energy sustainable communities.
In countries of the world with high temperature climates, it is increasingly recognized that space cooling in buildings using energy intensive air conditioning practices are not sustainable and contribute hugely to climate change. therefore, research and development of sustainable building services are vital to the decarbonization of the built environment agenda.
- Research focus: Passive and low carbon heating/cooling systems with novel materials.
I have also keen interests in research and the development of associated energy management solutions and processes for buildings.
