Experiments were carried out at continuously running (ON) and periodically running (ON/OFF) operation modes. Data was analyzed and a comparison in terms of cooling capacity, power input, coefficient of performance (COP), Carnot COP, and exergy efficiency was conducted. The comparison showed that DC compressors can be much more efficient than AC compressors in refrigeration units. © Springer-Verlag Berlin Heidelberg 2013.en10.1007/978-3-642-36645-1_33info:eu-repo/semantics/closedAccessCompressorDirect currentEnergy savingExergySolar energyVariable speedArticle22357365Q4
