Refrigerant.

摘要

A refrigerant mixture has a noncombustible fraction consisting essentially of nitrogen or other noncombustible gases, such as argon and neon, and a combustible fraction consisting of low molecular weight hydrocarbons such as methane, ethane and propane, and a flame or combustion retardant material, such as bromotrifluoromethane. The refrigerant is particularly suitable for microminiature refrigeration systems involving Joule-Thomson expansion to cryogenic temperatures of about 80 DEG K.
