The air conditioner high-pressure line is a component of the compression refrigeration unit provided in the design of a modern vehicle, on which the air temperature in the cabin depends. The line is designed for the transfer and circulation of refrigerant; it has plasticity and high flow capacity.

The operation of the high-pressure line

Car AIC brand High Pressure Line, air conditioning are aluminum cavities through which coolant flows from one important unit of the car air conditioner to another. Therefore, it is along them that the refrigerant moves first from the compressor to the condenser, from there to the dryer, from it to the evaporator. Throughout its entire journey, the coolant takes on either a liquid or a gaseous state, and reliable sealed pipes prevent it from leaking out. These components are responsible for ensuring that the refrigerant goes all the way without incident: so that cold air gets into the passenger compartment. Like any parts, lines are subject to wear: periodically they need to be replaced with new ones.
