This project deals with the thermal design and optimisation of a novel type of latent energy heat exchanger. This new heat exchanger overcomes the practical implementation problems of previous latent energy heat exchangers such as heat-wheels. The main application of this innovative heat exchanger will be to improve the capacity and efficiency of air conditioning systems. As the new heat exchanger is very compact it will be ideally suited for integration with air conditioning coils. Existing latent heat wheels are very bulky and are difficult to integrate into standard air conditioner installations.Read moreRead less

This project will provide knowledge for Australian industry to develop new energy efficient refrigerated display cabinets, putting Australia in the forefront of commercial refrigeration display cabinet technologies. This will have a significant impact on sustainability of our environment and will assist Australia to meet present and future international climate obligations by contributing to the reduction of greenhouse emissions. The Government has already introduced new MEPS levels, and are planning to increase these to more stringent levels in 2007. The development of the techniques proposed in this application will be essential for manufacturers if they are to economically meet these MEPS level requirements. Read moreRead less
Heat Transfer Enhancement Techniques for Air Conditioning and Refrigeration Equipment. The proposed Project will make significant contribution towards the both fundamental understanding of heat transfer enhancement using dimpled surfaces and the design of heat exchangers and, in particular to the application of dimpled surfaces in air conditioning and refrigeration industries. Unlike the previous CFD studies which have been made on the assumptions that the flow is steady and decoupled from the ....Heat Transfer Enhancement Techniques for Air Conditioning and Refrigeration Equipment. The proposed Project will make significant contribution towards the both fundamental understanding of heat transfer enhancement using dimpled surfaces and the design of heat exchangers and, in particular to the application of dimpled surfaces in air conditioning and refrigeration industries. Unlike the previous CFD studies which have been made on the assumptions that the flow is steady and decoupled from the heat transfer calculations in this Project the fully coupled problem will be solved, in which unsteady flows are allowed to occur over a dimpled surfaces. As a result we will be able to more accurately determine the resultant effects on the pressure drop and heat transfer. Read moreRead less
Thermal enhancement strategies and development of a high-performance micro-scale heat exchanger for thermoelectric refrigeration with large cooling loads. Traditional refrigeration essentially utilises CFC-refrigerants which are potent atmospheric pollutants causing widespread ecological damage. Devoid of such adversities, electronic heat pumping mechanism of thermoelectric principle offers a practical ?CFC-free? alternative for conventional cooling methods. While the current thermoelectric te ....Thermal enhancement strategies and development of a high-performance micro-scale heat exchanger for thermoelectric refrigeration with large cooling loads. Traditional refrigeration essentially utilises CFC-refrigerants which are potent atmospheric pollutants causing widespread ecological damage. Devoid of such adversities, electronic heat pumping mechanism of thermoelectric principle offers a practical ?CFC-free? alternative for conventional cooling methods. While the current thermoelectric technology adequately meets light cooling demand, its potential for heavy-duty refrigeration is critically undermined by ill-developed methods for dissipating heat from thermoelectric modules to coolants, and remains grossly under-utilised. The proposed work will devise novel heat transfer techniques for raising thermoelectric cooling thresholds to suit large heat loads and develop a thermally enhanced micro-scale heat exchanger for application in commercial thermoelectric refrigeration.Read moreRead less
