Improvement of the energy efficiency in refrigerating plants.

Author(s) : HERA D., DRUGHEAN L., GIRIP A.


Taking into consideration the potential decrease of energy consumption in the refrigeration plants, this paper presents a detailed analysis of every component of such a plant and proposes several solutions for improving energy consumption. Different compressor types were analysed, in order to decrease the power consumption, even in the case of small compressors with a small cooling capacity. Analyses of heat exchangers from refrigerant plants are also presented (evaporator, condenser, subcooler or super heater) emphasizing the boost of heat transfer phenomena using the turbulence shapes. In the "Applied Thermodynamics" Laboratory of the "Technical University of Civil Engineering" in Bucharest, Romania, the authors' team has determined, for different heat exchangers (e.g. shell and tube, improved shell and tube, with plate or with microchannels), the heat transfer characteristics for different functioning conditions.
