Heat recovery from refrigeration plants: Meeting load and temperature requirements☆
Abstract In refrigeration plants the heat extracted from the refrigerated medium and energy in the form of mechanical work from the compressor are discharged to the atmosphere through the condenser. In this paper a study of the alternatives for recovering this amount of energy to produce hot water, or warm air is reported. A basic thermodynamic analysis is carried out, showing the most appropriate conditions for heat recovery. A simulation model is also used for the prediction of performance in cases where temperature requirements are present. Data from an experimental unit are also presented and compared with the predicted results. Tests were performed over a range of condenser and evaporator temperatures.
