中文Introduction of Refrigerant
The refrigerant is a substance used in heat cycle system. It can realize reversible phase change from gas to liquid. In refrigeration system, liquid is first transformed to vapor in evaporator. Then, we use a compressor to pump out vapor, and fill it into the condenser. After that, the vapor becomes liquid. Our refrigerant is used in this system. It has good heat-conducting property, and can work under high temperature.
Compared with R12, R134a has better heat conductivity. This greatly reduces the
consumption of refrigerant. Besides, both of them have similar heat conductivity, so
modification of their refrigerating system is much easier.
It is particularly suitable for automobile refrigerating system. Its boiling point is
-26.2℃ ...
It is free of corrosion, as its moisture is less than 0.001%. Besides, its purity is
above 99.9%, its acidity is lower than 0.00001% and its residue on evaporation is less
than 0.01% .
It is extensively used in household air conditioners, business air-conditioners, central
air conditioning, mobile air conditioning, heat pump water heaters, dehumidifiers,
freezing desiccators, and more ...
Our A20 (5/16, 13/32, 1/2, 5/8) air conditioner hose is composed of inner rubber layer,
nylon layer, middle rubber layer, hose carcase, and external rubber layer. Its unique
structure helps it to bear a high compression ratio.
Our A20 air conditioner hose has properties of being damp proof, heat resistant and cold
resistant ...
Our A10 (5/16, 7/16, 1/2, 3/5) air conditioner hose consists of inner rubber layer,
nylon layer, middle rubber layer, hose carcase, and external rubber layer. This
structure enables it to bear a high compression ratio and have advantages of damp
proofing, heat resistance, and cold resistance.
Our A10 air conditioner hose is extensively applied to air-conditioning system of cars,
trucks, buses ...
Our auto air compressor oil is particularly designed for automobile air-conditioning
system. It is mainly composed of ISO grade polyalkylene glycol (PAG) lubricants and can
be used together with R134a refrigerants.
The compressor oil can be used in remoulded cars which use R12 mineral oil before ...
