Currently on the market of the common automobile air conditioning refrigerant type: everything, R22
, R404A, R407C brands: desire, honeywell, beauty,, dongyue, daikin packing specification: 300 g, 9.
5 kg, 10 kg everything refrigerants such as everything is now internationally recognized one of the main refrigerating substitute R12, commonly used in automobile air conditioning, commercial and industrial refrigeration
system, and used as a foaming agent in hard plastic insulation materials production, can also be used to configure other mixed refrigerants, such as R404A and R407C, etc.
Main USES: the main substitute R12 used as refrigerant, a large number of used in automobile air conditioning, refrigerator refrigeration.
Refrigerant R407C physicochemical properties: under atmospheric pressure, R407C is a chlorine fluoroalkane non azeotropic mixed refrigerants, colorless gas, storage is compressed in the cylinder of liquefied gas.
The ODP is 0, so is not destruction of atmospheric ozone environmental protection refrigerant R407C.
Main use: R407C is mainly used to replace R22, clean, low toxic, non-combustible, refrigeration effect is good wait for a characteristic, a large number of used in household air conditioner, small and medium-sized central air-conditioning.
Physical and chemical properties: refrigerant R404A R404A shall not is a kind of non azeotropic mixed refrigerants of chlorine, colorless gas under atmospheric pressure, store is compressed in the cylinder of liquefied gas.
The ODP is 0, so R404A ozone layer is not to undermine the atmosphere environmental protection refrigerants.
Main use: R404A is mainly used to replace R22, r114, clean, low toxic, non-combustible, refrigeration effect is good wait for a characteristic, a large number of used in cryogenic refrigeration system.
Detailed parameter warm reminder: at present, a lot of imports of automotive air conditioning device is to use 134 a refrigerant, and 134 a refrigerant on the market price is about three times as much as R12, so some people in the car when installing air conditioner added refrigerant to save a few money or convenience, change the 134 a, air conditioning system to pump refrigerant R12, although can send the cold wind, but will damage the compressor.
2002 years after the production of cars, air conditioning system is especially designed for the 134 a, if add other refrigerant R12, R22, use for a long time, the light will leak, result in automobile air conditioning refrigeration result is bad, serious, will cause irreversible damage to the car air conditioning system.
So consumers in choosing a car air conditioning refrigerant, must be careful to distinguish, had better choose big manufacturer, trustworthy brand.
