what is R-134a refrigerant give the advantages and property?

Answer 1

Production of chlorofluorocarbons (CFCs) has been phased out (Refrigerant like R-10,R-11,R-12) due to their potential to deplete the ozone layer which is 3 mm thick and filtering UVrays emmiting from sun.

Environmentally acceptable replacement compounds are therefore needed for use in existing medium and low temperature refrigeration applications.
Refrigerant R134a or HFC-134a was developed to meet these needs.
Refrigerant R134a or HFC-134a is a commercially available hydrofluorocarbon (HFC) refrigerant for use as a long-term replacement for R-12 in new equipment and for retrofitting medium temperature CFC-12 systems.

R-134a:
1,1,1,2-tetra-fluoroethane CH2FCF3 R134a is a single hydrofluorocarbon or HFC compound.
No chlorine content, no ozone depletion potential.
Modest global warming potential.
ODP = 0 and GWP = 1300 .
Boiling point = −26.6 °C (−15.9 °F).
Density and phase 0.00425 g/cm³, gas.
Solubility in water Insoluble.
Melting point -103.3°C (169.85 K) .
ISO 17584:2005 is applicable to the refrigerants R12, R22, R32, R123, R125, R134a, R143a, R152a, R717 (ammonia), and R744 (carbon dioxide) and to the refrigerant blends R404A, R407C, R410A, and R507.

*1,1,1,2-Tetrafluoroethane is an inert gas used primarily as a "high-temperature" refrigerant for domestic refrigeration and automobile air conditioners. Other uses include plastic foam blowing, as a cleaning solvent and as a propellant for the delivery of pharmaceuticals (e.g. bronchodilators), canned air, and in air driers, i.e., for removing the moisture from compressed air. Moisture present in compressed air has a harmful effect on pneumatic systems. Tetrafluoroethane has also been used to cool computers in some overclocking attempts. It is also commonly used as a power source for airsoft airguns.

Answer 2

Refrigerant R134a

Answer 3

R134 Refrigerant

Answer 4

1,1,1,2-Tetrafluoroethane, also called simply tetrafluoroethane, R-134a or HFC-134a, is a refrigerant without an ozone depletion potential and thermodynamic properties similar to R-12 (dichlorodifluoromethane). It has the formula CH2FCF3, and a boiling point of −26.6 °C (−15.9 °F).
R-134a first appeared in the early 1990s as a replacement for Dichlorodifluoromethane (R-12), which has significant ozone depleting properties.
Tetrafluoroethane is a clear liquid which boils at room temperature and can be extracted from common canned air canisters by simply inverting them during use.
