With a background in mechanical engineering and energy technology, research activities and interests include both energy equipment design, development and applications, as well as energy system planning and management.
Energy conservation and management
in industries and in large commercial buildings in Thailand is an area which still needs a lot of research. The main topics include energy analysis of potential savings, thermal energy storage (cool/ice storage) for air-conditioning system, cogeneration system for industries which require both heat and electricity simultaneously, industrial waste heat recovery and evaporative cooling.
The transportation sector accounts for about 40% of total energy demand in Thailand and, in addition, fuels used are mainly from imported petroleum. This not only affects the country economy but burning fossil fuels also produces air pollution as well as CO2
which is a main greenhouse gas emission. Research topics under investigation include the development of Bangkok driving modes for various types of vehicles, assessment of the use of catalytic converters in gasoline cars, and the effects of using vegetable oils in diesel engines.
Another field of research to be mentioned is concerned with solar energy
; both thermal and electrical applications. Interesting topics under consideration are the design and development of low cost solar water heaters using local materials, solar-photovoltaic refrigerators for use in remote areas where electricity from the utility grid is not available, modeling of solar PV/thermal systems under various types of applications, development of standard methods for testing solar energy equipment, software packages for optimum sizing of solar energy systems.
