1986年8月5日 · R142B: A NEW REFRIGERANT FOR HIGH TEMPERATURE HEAT PUMPS. THIS STUDY PRESENTS THE RESULTS OBTAINED WITH A HIGH TEMPERATURE HEAT PUMP USING THE R142B. THE THERMODYNAMIC CHARACTERISTICS OF SATURATION OF THIS FLUID ARE BETWEEN THE ONES OF THE R12 AND THE ONES OF THE R114.

1-chloro-1,1-difluoroethane appears as a colorless, odorless gas shipped as a liquid under own vapor pressure. Contact with the unconfined liquid may cause frostbite by evaporative cooling. Easily ignited. Vapors heavier than air. A leak may be either liquid or vapor. May asphyxiate by the displacement of air.

1990年1月1日 · R142b is not totally halogenated, so its coefficient of ozone depletion is low. This report presents performances of heat pumps using R142b and different types of compressor (open type piston compressor, single screw compressor, open type compound compressor).

Foranext ® products, such as R-22 and R-142b, are at the heart of the chemistry leading to high performance fluoropolymers such as PTFE and PVDF. Arkema combines its extensive expertise in both engineering polymers and industrial scale fluorination to develop new monomers for fluoropolymers, with improved attributes and performance.

Our investigations showed that R142b was a good answer to the problem. Tests of stability made at 160•c, in sealed test-tubes, in presence of oil and the ~etals which go into the construction of a heat pump, proved that R142b is as stable R114.

Saturated Vapor Pressure, Boiling Point (dew point), Latent Heat of Vaporization are saturated properties, just enter One parameter to calculate them!

R142b is a colorless gas and mainly used in refrigerating systems at high temperatures, on-off thermostats, and intermediate in the aviation propellant!
