An investigation of refrigerant leakage in commercial refrigeration [PDF]

International Journal of Refrigeration, 2017
Given that refrigerant demand is set to rapidly increase, long term solutions for leakage prevention are required to effect change in the industry. This paper presents the results of a project which investigated refrigerant leakage within two of the UK’s major supermarket chains. Leakage data from 1,464 maintenance records were analysed.

A Numerical Study of Refrigerant Leakage From a Propane-Based Refrigeration System

ASME 2023 Heat Transfer Summer Conference, 2023
Abstract Low Global Warming Potential (GWP) refrigerants, e.g. Propane (R290) (GWP = 3) and R1234yf (GWP = 4), are becoming a popular choice among refrigeration and HVAC systems, such as vending machines and air conditioning. However, most of Low GWP refrigerants are flammable (ASHRAE class A2 or A3), so safety is a very important ...
