Experimental investigation of the performance of a single-stage auto-cascade refrigerator [PDF]
Heat and Mass Transfer, 2015 Auto-refrigerating cascade (ARC) systems possess many advantages comparing with traditional cascade refrigeration systems. This work proposed a novel ternary mixture, R600a/R23/R14, for ARC systems for 190 K applications. The performance of the ternary mixture and the influences of compositional ratio and bypass scheme were assessed in a modified ...

Experimental Study of the effects of Throttle valve on Auto-cascade Refrigeration System [PDF]
Proceedings of the 3rd International Conference on Material, Mechanical and Manufacturing Engineering, 2015 The objection of this article is to optimize auto-cascade refrigeration system. This refrigeration system use multiple mixture (R22/R23/R14) as the refrigerant, which is driven by the single-stage compressor. Throttle is an important composition of auto-cascade refrigerant system, which impact on evaporation temperature and refrigeration efficiency ...

The Relation of Performance Parameters for a 150K Auto-Cascade Refrigeration System
Research Journal of Applied Sciences, Engineering and Technology, 2013 The performance parameters of a single compressed and four-stage segregating auto-cascade refrigeration system were developed in this study. The temperature of the cryogenic tank went down relatively slow with the evaporating temperature and the refrigerant temperature for W. When the state of system is steady, the suction pressure of the compressor is

Biotechnology and Bioengineering, EarlyView.ABSTRACT A recombinant whole‐cell biocatalytic approach provides several advantages over isolated enzymes, such as improved enzyme stability, in vivo cofactor regeneration, and the facilitation of cascade reactions within a single cell. Whole‐cell biocatalysis has gained attention in medicinal opioid production, due to its technical and economic ...

Business Strategy and the Environment, EarlyView.ABSTRACT Circular product design (CPD) is central to advancing the circular economy by enabling the narrowing, slowing, and closing of resource flows. Yet, its implementation remains persistently challenging for firms. Prior research has largely framed these challenges as discrete barriers, overlooking the structural contradictions embedded in CPD ...
