What are the positive pressure and negative pressure of a hose
Air conditioner hose is mainly used for conveying liquid or gaseous refrigerant, which can be used of air conditioning system in all kinds of compressor oil in – 40-130 ℃. Weather resistance, ozone resistance, lasting heat resistance and oil resistance. The air conditioning hose with nylon lining, greatly enhance the penetration resistance of the hose, reduce the possibility of a refrigerant of atmospheric ozone depletion.
So why do car air conditioners use hoses? There are two reasons for the use of hoses for automobile air conditioners:
- Most automobile air conditioners use R134a as refrigerant, and the high pressure of this refrigeration system is relatively low, generally less than 15kg.
- The compact structure of the car and the high maintenance frequency of the car can be considered to use the rubber air conditioning hose.
