Abstract

Abstract: The present study evaluates the possibilities of increasing efficiency in refrigeration and heat pump systems based on compression cycles by means of using compressor heat losses. In order to do this, the work been divided into the following parts: presentation of the used model of a thermoelectric device in order to estimate the amount of energy recovery from the heat source, an experimental test under several contour conditions to estimate the real temperature difference maintained in a thermoelectric module in contact with the compressor wall and, based on this information, an estimation of the potential amount of energy that can be recovered by this kind of system. Highlights: Energy harvesting potential in the compressor heat losses. Model of thermoelectric module. Capacity modulation in refrigeration systems by the use of thermoelectric effect. COP improvement through the thermoelectric effect in refrigeration systems.
