What is the definition of refrigerant in chemistry?
A refrigerant is a working fluid used in the refrigeration cycle of air conditioning systems and heat pumps where in most cases they undergo a repeated phase transition from a liquid to a gas and back again.
What are refrigerant gasses?
A refrigerant is a compound used in a heat cycle that reversibly undergoes a phase change from a gas to a liquid. Traditionally, fluorocarbons, especially chlorofluorocarbons, were used as refrigerants but they are being phased out because of their ozone depletion effects.
What is refrigerant made of?
In addition to fluorine and carbon, Freons often contain hydrogen, chlorine, or bromine. Thus, Freons are types of chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), and related compounds. The name Freon is a trademark registered by E.I. du Pont de Nemours & Company.
What is refrigerant example?
Traditionally, fluorocarbons, especially chlorofluorocarbons (CFC’s), were used as refrigerants, but they are being phased out because of their ozone depleting effects. Other common refrigerants used in various applications are ammonia, sulfur dioxide, and non-halogenated hydrocarbons such as propane.
What is refrigerant and its properties?
The refrigerant is a heat carrying medium which during their cycles (i.e. compression, condensation, expansion, evaporation) in the refrigeration system absorb heat from a low temperature system and discard the heat so absorbed to a higher temperature system. Properties of a good refrigerants: Low boiling Point.
What are refrigerants used for?
A refrigerant is chemical compound that is used as the heat carrier, which changes from gas to liquid and then back to gas in the refrigeration cycle. Refrigerants are used primarily in refrigerators/freezers, air-conditioning, and fire suppression systems.
What is the function of refrigerant?
How do refrigerants work?
As refrigerant absorbs heat from indoor air, it transitions from a low-pressure gas to a high-pressure liquid. Air conditioning components send the refrigerant outside where a fan blows hot air over the coils and exhausts it to the exterior. The refrigerant then cools down and turns back into a low-pressure gas.
What is refrigerant classification?
There are four main groups of refrigerants and they are determined by their chemical constituents but are generally classified as Chlorofluorocarbons (CFCs), Hydro chlorofluorocarbons (HCFCs), Hydro fluorocarbons (HFCs) and Natural Refrigerants [7]. …
What are the three properties of refrigerant?
Physical Properties of Refrigerants
- Low Freezing Point. Refrigerants should have low freezing point than the normal operating conditions.
- Low Condensing Pressure.
- High Evaporator Pressure.
- High Critical Pressure.
- High Vapor Density.
- High Dielectric strength.
- High Latent Heat of Vaporization.
- High Heat Transfer Coefficient.

What is the best refrigerant?
Although there are various types of refrigerants, R-32 is a new refrigerant currently receiving the most interest. Because R-32 efficiently conveys heat, it can reduce electricity consumption up to approximately 10% compared to that of air conditioners using refrigerant R-22.
