Experimental Observation of CO2 Dry-ice Behavior in an Evaporator/Sublimator
Yamasaki, Haruhiko; Yamaguchi, Hiroshi; Hattori, Kazuyuki; Nekså, Petter (Journal article; Peer reviewed, 2017)In the evaporator/sublimator process of CO2 (R744) ultra-low temperature cascade heat pump system, it is known, as a problem, that dry-ice blockage makes the system operation fail. The design of an expanding channel for ... -
Solar heat recovery system using CO2 as working fluid
Yamasaki, Haruhiko; Wakimoto, Hiroyuki; Yamaguchi, Hiroshi; Nekså, Petter (Chapter, 2020)This article proposes a solar water heater system induced by natural convective flow using supercritical CO2 as a working fluid. The proposed solar water heater can produce thermal energy as hot water from solar thermal ...
