WebMay 15, 2014 · The basic transcritical CO2 systems exhibit low energy efficiency due to their large throttling loss. Replacing the throttle valve with an ejector is an effective measure for recovering some of the energy lost in the expansion process. In this paper, a thermodynamic model of the ejector-expansion transcritical CO2 refrigeration cycle is developed. The … WebMar 30, 2024 · Magnetic anisotropy strongly influences the performance of the magnetocaloric effect. We investigated the magnetocaloric properties of the NdAlGe single crystal with I4 1 md structure. The temperature-dependent magnetization revealed significant anisotropic properties; stable antiferromagnetic transition at T N = 6 K for H//a …
