20.500.12556/DKUM-50215 Analysis of two-stage high- temperature heat pump efficiency The paper shows the potential benefit of using low temperature heat sources with high temperature pumps. Two-stage heat pumps with flash unit and heat exchanger are described. To determine the characteristic parameters of the twoheat pumps a computer program was designed, with which we could determine the dependence of COP and compressor pressure ratios from evaporating temperature. An economic analysis of the justification of the use of heat pumps was made. heat transfer high temperature heat pumps computer programme economic analysis true false false Angleški jezik Neznan jezik Delo ni kategorizirano 2015-07-10 12:37:07 2015-07-10 12:37:07 2022-05-29 03:06:19 2021-05-09 03:25:40 2012 0 0 str. 350-363 iss. 5 Vol. 6 2012 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 66 16535574 2074-1308 URN:SI:UM:DK:LIM1CLSY http://www.naun.org/multimedia/UPress/saed/16-564.pdf 1 https://dk.um.si/Dokument.php?lang=slv&id=74773 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
