Energy Optimization for Transcritical CO2 Heat Pumps for Combined Heating and Cooling and Thermal Storage Applications

A transcritical heat pump (THP) cycle using carbon dioxide (CO2) as the refrigerant is known to feature an excellent coefficient of performance (COP) as a thermodynamic system. Using this feature, we are designing and building a system that combines a water-to-water CO2 heat pump with both hot and cold thermal storages know as Thermal Battery (TB) (Blarke, 2012). Smart and effective use of inte...

On the robustness, effectiveness and reliability of chemical and mechanical heat pumps for low-temperature heat source district heating: A comparative simulation-based analysis and evaluation

Our physical environment is endowed with unlimited amount of natural and artificial sources of energy at various low exergetic levels which leaves them almost impossible to be thermally utilized at such source states. The thermal upgrading of these low exergetic energy sources could render them amenable to various practical thermal usages. This paper provides a comparative study through simulat...

Solar District Heating with Seasonal Storage in Attenkirchen

Energy conservation through energy storage combined with intensive use of renewable energies will support the effort to meet the objectives of reduction of climatic gases formulated in the Kyoto protocol. Potential studies have shown that in Germany about 20 – 25 % of the end-energy consumption for space heating and domestic hot water can be covered by solar energy. Solar district heating with ...

Network synthesis for district heating with multiple heat plants

In this paper the first results of a new method for the configuration of district energy systems are presented. District energy systems are believed to help decreasing the CO2-emissions due to energy services (heating, cooling, electricity and hot water), by implementing polygeneration energy conversion technologies. However, because polygeneration technologies are complex, it is meaningful to ...

Influence of Non-Uniform Wall Temperature on Local Heat Transfer Coefficient in a Rotating Square Channel

 Abstract: This paper presents the results of an experimental examination of the effect of non-uniform wall temperature on local heat transfer coefficient in a rotating smooth-walled square channel. Three different thermal boundary situations were investigated: (a) even and odd (four) wall uniform temperature, (b) even and odd (four) wall uniform heat flux, and (c) even (leading and trailing) w...
