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

Molecular dynamics simulation of non-azeotropic refrigerants separation in auto-cascading refrigeration [PDF]
E3S Web of Conferences, 2019 The core problem of auto-cascading refrigeration is the separation of non-azeotropic refrigerants. The separation effect of mixed refrigerant directly determines the refrigeration effect of auto-cascading refrigeration system and the value of COP. The microscopic molecular dynamics simulation method is applied to the refrigeration system, and the ...
