Difluorochloroethane (R-142b refrigerant)

R-142b refrigerant, alias R142b, freon 142b, F-142b, HCFC-142b, etc., Chinese name difluorochloroethane, English name 1-chloro-1,2-difluoroethane, chemical formula CClF2CH3, trade name Reflube 142b. Since R-142b belongs to HCFC-like substances (the second batch of ODS-depleting Substances) - destroys the ozone layer and has a greenhouse effect, it has ceased in developed countries (EU, Japan, USA) In the new air conditioning, refrigeration equipment on the initial installation; China is currently for R142b refrigerant production, initial installation, and then add no restrictions.

R-142b main purpose

R-42b is used as a high-temperature refrigerant for general use. (R142b) is mainly used for refrigeration and air conditioning systems (high temperature air conditioning) in high temperature environments, heat pumps, important components of various compounding refrigerants, and polymer (plastic) foaming , Thermostat control switch and aviation propellant intermediates, as well as for chemical raw materials.

One-time cylinder Packing: 13.6kg / bottle; reusable cylinder packaging (need to recover packaging cylinders): 400kg / bottle, 800kg / bottle.

R-142b storage and transportation

R-124 refrigerant cylinders are pressure vessels, stored away from fire, heat, to avoid direct sunlight, usually stored in a cool, dry and ventilated warehouse; handling should be light, light unloading, to prevent cylinders and valves Accessories are damaged.

R-142b supporting the use of refrigeration oil

In general, the refrigerating oil used in the R-142b refrigerant is: Suniso 4GS, 5GS, Capella WF68, LUNARIA KA56, etc .; in the different equipment, different applications where the final use of frozen oil, should follow the refrigeration compressor and refrigeration (air conditioning) Equipment manufacturers to recommend, or according to the refrigeration compressor, refrigeration equipment to determine the specific circumstances to use the same design and technical requirements of the freezer lubricants, that is, the choice of reciprocating refrigerating machine oil.
