Performance of hydrocarbon refrigerants in a refrigerator with liquid line magnet and CNT nano-lubricant [PDF]
Heliyon, 2023 The issues of flammability associated with A3-class hydrocarbon-based refrigerants are controllable by limiting their mass charges. However, these reductions in their mass charge below certain limits deteriorate their performance efficiency.

Thermodynamic Analysis of Low GWP Refrigerant Mixtures in a Refrigerator as Replacement to R-134A [PDF]
Journal of Mechanical Engineering, 2019 Chlorofluorocarbons and hydro chlorofluorocarbons (HCFCs) are replaced by hydroflourocarbons (HFCs) which is not harmful to the ozone layer. However, few of HFCs have a relatively high global warming potential (GWP) and are subject to further examination

Performance analysis of a retrofitted refrigerator using eco-friendly refrigerant [PDF]
The Holistic Approach to Environment, 2023 The use of refrigerants with a global warming potential (GWP) greater than 150 is banned in small and medium-sized refrigerators in accordance with the European F-Gas policy. Therefore, the suitability of retrofitting an existing refrigerator using a low

Silk Replaces Refrigeration [PDF]
Science, 2012 Bioengineering Both vaccines and antibiotics lessen the burden of disease—one before the fact and one after. Successful treatment often requires a “cold chain,” in which the vaccine or antibiotic must be refrigerated from production to patient. Failure to sustain the cold chain results in loss of therapeutic efficacy, but maintaining it can be ...

High-global warming potential F-gas emissions in California: comparison of ambient-based versus inventory-based emission estimates, and implications of refined estimates. [PDF]
, 2014 To provide information for greenhouse gas reduction policies, the California Air Resources Board (CARB) inventories annual emissions of high-global-warming potential (GWP) fluorinated gases, the fastest growing sector of greenhouse gas (GHG) emissions ...
