Abstract
This work investigates the result of an experimental study carried out to determine the performance of a domestic refrigerator when a propane/butane mixture is used as a possible replacement to the traditional refrigerant CFC 12. The used propane/butane mixture is liquefied petroleum gas (LPG) which is locally available and comprises 24.4% propane, 56.4% butane and 17.2% isobutane. The LPG is cheap and possesses an environmentally friendly nature with no ozone depletion potential (ODP). It is used in Jordan for cooking purposes. The refrigerator used in the present study is of medium size with a gross capacity of 320 l and is designed to work on CFC 12. The performance parameters investigated are the refrigeration capacity, the compressor power and the coefficient of performance (COP). The refrigerator worked efficiently when LPG was used as refrigerant instead of CFC 12. The evaporator temperature reached −15°C with COP value of 3.4 at a condenser temperature of 27°C and an ambient temperature of 20°C. The refrigerator has been working satisfactorily since March 1994 without noticing any side effects or needing any adjustments. The results of the present work indicate the successful use of this propane/butane mixture as an alternative refrigerant to CFC 12 in domestic refrigerators.
