R134a is using as refrigerant in most of domestic refrigerators and freezers but due to its high gwp 1 , kyoto protocol called for phase out of r134a and replace it with new low odp 2 and gwp. Thus, air venting of r134a one filling from a domestic refrigerator (about 140 gm) corresponds to ejection of 170 kg of со 2 in europe about 448 gm of со 2 is formed at production of 1 kwt/h of power, that is, this ejection corresponds to production of 350 kwth of power. Included in ashrae (1998) [9] for pure (r-134a),(r-22), and (r-410a) the object of these curves is to establish the required capillary refrigerant flow rate for specified geometry and entering condition.

Practical household refrigerators were introduced in 1915 and gained wider acceptance in the united states in the 1930s as prices fell and non-toxic, non-flammable synthetic refrigerants such as freon-12® (r-12) were introduced.

Since 1992-1994, the refrigerants used are r134a and isobutane experts agree that these 2 refrigerants have similar performances in terms of refrigerating capacity and energy efficiency 4 after being used for a. Ecofriendly refrigerant used in the domestic refrigerator the performance of the refrigerator will be studied using r134a refrigerant and mixture of propane r290 and isobutene r600a.

Note: r134a has a global warming potential (gwp) of 1300 with respect to carbon dioxide there is currently serious consideration of replacing it with r744 (carbon dioxide) in refrigeration and heat pump applications. Vapour pressures than r 12 or r 134a, in the standard operational temperature range for a refrigeration system to better observe the impact of substituting r 12 for r 600a. Alternatives to replace r134a in domestic refrigerators the above literatures revealed that many investiga- tors reported the performance of r152a and hydrocar. Refrigerant leaks are uncommon with modern domestic refrigerators but if they do occur, there is a good chance they will destroy your refrigerator it is technically possible to find refrigerant leaks, reclaim any remaining refrigerant, fix the leak, evacuate the system and recharge the refrigerant, but most of the time it is not economically.

R-134a refrigerant pressure temperature chart - r-134a is an inert gas also known as tetrafluoroethane and is used in air conditioner systems r134a is used as a chemical refrigerant in automotive and domestic use air conditioners such as chilled water systems in both commercial markets and industrial markets. Studies r134a was used the refrigerant, and a mixture of mineral oil tio2 was used as the lubricant they found that the refrigeration system with the nanorefrigerant worked normally and efficiently and the energy. Refrigerant gas is a chemical product used in refrigerators, freezers, air conditioners and heating, ventilating and air conditioning units ()these gases, which have very low evaporation points, are condensed under pressure to chill the air. The almost universal refrigerant gas for domestic refrigeration today that is iso-butane based whilst flammable this gas is used in such low quantities in domestic refrigeration that it is extremely unlikely to be of any risk, even large systems used very small gas charges, normally well under 80g of gas with many, if not most half that or less.
