Exempel på refrigerant

• 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.

• This recommends specifying refrigerants which do not cause both ozone depletion and global warming.

• One supplier expressed an interest in tendering and offered a propane-based refrigerant for the project.

• However, no specific assessment has been made of the risks to public safety from the use of volatile and flammable hydrocarbons as refrigerants.

• This is a commercially available non-ozone depleting refrigerant.

• There are also specific credits for use of non-ozone depleting refrigerants and leakage prevention systems.

• A robust plan for the safe handling and recovery of the refrigerant when the units are disposed of will be put into place.

• There is refrigerant leakage detection installed on some equipment but information on the number is not readily available.
