Selection guide for air compressor

Selection of working pressure (exhaust pressure): When the user is preparing to purchase an air compressor, first determine the working pressure required by the air end, add a margin of 1-2 bar, and then select the pressure of the air compressor (the margin is considered from the air compressor The pressure loss from the installation site to the actual gas end pipeline distance, according to the length of the distance between 1-2 bar, appropriately consider the pressure margin)

Why does the use of cold and air conditioning in a car increase fuel consumption because the car cannot carry a compressor

Automotive air conditioning system _ compressor power is not high Knowledge point: The principle of the "refrigeration system" of automobile air conditioners is the same as that of domestic air conditioners. Both use compressors to drive refrigerants to achieve cooling by the principle of "evaporation and heat absorption".
