Optimization of a vapor injection refrigeration cycle using hydrocarbon mixed refrigerants

International Journal of Refrigeration, 2019
Abstract Refrigeration systems are major consumers of electrical energy in many process industries. Hydrocarbons have regained interest as refrigerants because of the increasing restrictions applied to halogenated fluids. In this work, the use of hydrocarbons mixed refrigerants and an alternative flash tank with vapor injection (FTVI) refrigeration ...

Performance of two mixed refrigerant processes providing refrigeration at 70K

Cryogenics, 2016
Abstract Mixed refrigerant process refrigerators are ideal for use in superconducting transformers, fault current limiters, etc. placed in a liquid nitrogen bath. Traditional mixed refrigerant processes used above 70 K cannot be used in these applications. The performance of two mixed refrigerant processes suitable for the above applications has been

Testing of the mixing refrigerants HFC152a/HFC125 in domestic refrigerator

Applied Thermal Engineering, 2005
Abstract The performances of a refrigeration cycle of a 1,1-difluoroethane/pentafluoroethane (HFC152a/HFC125) mixture used as a refrigerant for domestic refrigerators were calculated and analyzed in detail. The results of the theoretical analysis indicate that the HFC152a/HFC125 mixture in the composition of 0.85 mass fraction of HFC152a has a ...

Performance of mixed refrigerant cascade refrigerator for cooling a space simulation chamber

Indian Journal of Cryogenics, 2014
A mixed refrigerant cascade (MRC) refrigeration system has been developed to replace a conventional two-stage cascade refrigeration system for the cooling of space simulation chambers. A fast cool down of the refrigerator to 193K within a time of 16 min is achieved.

Effect of dilutant concentration on the performance of environment-friendly mixed refrigerants used in domestic refrigerators

Environmental Science and Pollution Research, 2022
This paper presents the environment-friendly mixture compositions of hydrocarbons (HC)- and hydrofluorocarbon (HFC)-based ternary mixtures that can be better alternatives for R134a in domestic refrigeration units. Combustible refrigerant HCs (R290, R600, R600a) and HFCs (R152a and R161) are used along with the dilutants R13I1, R245fa, R134a, R227ea ...

Synthesis of Mixed Refrigerant Cascade Cycles

Chemical Engineering Communications, 2002
This paper considers the synthesis of refrigeration systems with refrigerant mixtures as working fluids. The employed refrigeration topology encompasses features from industrial liquefaction of natural gas (LNG) systems. This configuration consists of a combination of horizontal and vertical cascades generalizing the vertical cascade of pure ...
