Energy performance of supermarket refrigeration and air conditioning integrated systems

Energy Analysis of Various Supermarket Refrigeration Systems

Modeling and analysis work was done on various supermarket refrigeration systems for their energy efficiency, TEWI (Total Equivalent Warming Impact), and annual operating cost. The systems which were modeled in detail include parallel racks, distributed, self-contained, glycol secondary loop, and CO2 secondary loop (medium temperature) and cascade (low temperature). Based on R404A modeling resu...

A Review on Developments of Thermoelectric Refrigeration and Air Conditioning Systems: a Novel Potential Green Refrigeration and Air Conditioning Technology

In recent years, with the increase awareness towards environmental degradation due to the production, use and disposal of ChloroFluoro Carbons (CFCs) and Hydro Chlorofluorocarbons (HCFCs) as heat carrier fluids in conventional refrigeration and air conditioning systems has become a subject of great concern and resulted in extensive research into development of novel refrigeration and space cond...

European Supermarket Refrigeration Systems Eco-Efficiency Considerations

Fluorinated hydrocarbon refrigerants have especially in Europe been drawn into the focus of the public debate concerning the background of reducing greenhouse active substances. This debate concentrates mainly on the GWP (Global Warming Potentials) properties of the substances. To step forward from a material based discussion to a useful dialogue about substances in their respective application...

Waste Heat Recapture from Supermarket Refrigeration Systems

Energy Efficient Hospitals Air Conditioning Systems

Energy Efficiency and Indoor Air Quality in the healthcare applications and particularly in surgical operating theatres are important features in modernized designs. The various reasons for deviation from obtaining optimum IAQ and energy efficient buildings are listed. The air conditioning systems serving the operating rooms require careful design to minimize the concentration of airborne organ...
