Study on the Performance of Very High Temperature Heat Pump Mixtures

Translated Abstract

Good　working　fluid　is　one　of　the　keys　to　the　development　of　very　high　temperature　heat　pump　technology.In　this　paper,according　to　the　principle　of　complementary　advantages,four　non-azeotropic　mixtures　MB1,MB2,MB3　and　MB4　are　proposed　for　very　high　temperature　heat　pumps　with　heating　temperatures　greater　than　140　℃,and　the　cycle　performance　and　optimal　ratio　of　these　four　mixtures　are　studied　under　the　conditions　of　evaporation　temperature　of　50　℃,70　℃　and　90　℃　and　condensation　temperature　of　140　℃-160　℃.The　results　show　that　benzene,cyclopentane,toluene,acetone　and　R13336mzz(Z)can　be　used　as　components　of　the　mixtures　of　the　heat　pump　at　the　heating　temperature.The　four　mixtures　have　good　performance,among　which　the　cycle　performance　of　MB2　is　the　best　among　the　proposed　mixed　working　fluids,and　the　COP　reached　2.4　and　the　exergy　efficiency　reached　58.9％under　the　conditions　of　evaporation　temperature　of　50　℃　and　condensation　temperature　of　160　℃.Under　the　conditions　of　evaporation　temperature　of　90　℃　and　condensation　temperature　of　160　℃,the　COP　of　MB2　reached　4　and　the　exergy　efficiency　reached　62.6％.The　cycle　performance　of　other　mixtures　was　improved　compared　with　the　main　component　benzene,and　the　flammability　of　MB4　was　lower　than　benzene.
