0 a chemical substance that can be used to make or keep things cold:
Chlorofluorocarbons have been used widely in the production of refrigerants like Freon.
Alternative refrigerants may be part of the answer, but there is now strong interest in more radical alternatives to air conditioning.
The refrigerant evaporates at the evaporator and collects heat from the water.
The input and output mass flow rates, pressure, enthalpy, and temperature of the refrigerant are identical.
The thermodynamic properties of the refrigerant are identical.
Spectroscopic analysis of fire suppressants and refrigerants by laser induced breakdown spectroscopy.
The main substances attributed to the depletion of atmospheric ozone are halogenated hydrocarbons, chemicals invented in 1928 as refrigerants.
The standard allows for hydrocarbons, which are flammable, being used as a refrigerant in certain circumstances instead of the usual hydrofluorocarbons, which are inert.
Guidance on refrigerants and air conditioning will be issued next year.
