primer momento para estos tipos de aire acondicionado para autos utilizaba como líquido refrigerante uno llamado clorofluorocarbono-12, conocido como Freón, pero como dañaba la capa de ozono, en 1995 se dejó de fabricar. Actualmente se usa R-134, el único refrigerante alternativo aceptado, por lo que en todos los autos fabricados del ’95 para acá, podemos encontrar ese fluido. Este debe ser siempre un líquido con un punto de ebullición bajo, dado el momento en que debe evaporarse. Por ello mismo es que la presión en el evaporador debe ser también baja para se evapore el refrigerante y de esta forma remueva el calor del interior del auto.
si, para los autos las presiones que se manejan son la siguientes con el auto encendido y el sistema de refigeracin en marcha la presion de baja anda en 35 psi. ya aselerando a 3000 revoluciones puede bajar a 20 psi ,, por el lado de alta anda en 150 a 200 psi..para todos los sistemas automatriz son iguales las presiones ,, siempre y cuando usen 134A y R-12 o, mo49 , como refrigerantes

first time for these types of air conditioning for cars used as a coolant called chlorofluorocarbon-12, known as Freon, but as damaging the ozone layer in 1995 was discontinued. Currently using R-134, the only accepted alternative refrigerant, so that all cars made from '95 here, we find that fluid. This should always be a liquid with a low boiling point, since the time that must be evaporated. Thus it is that pressure in the evaporator must also be low to evaporate the refrigerant and thereby remove heat from inside the car. if, for cars handle the pressures are following the car on and the system pressure up refigeracin low walks in 35 psi. and at 3000 revolutions aselerando can drop to 20 psi, for the high side walks in 150 to 200 psi for all systems .. automatriz pressures are equal, as long as use 134A and R-12 or, MO49, as refrigerants Refrigeration Pressure Coolant automotive R-134 35 psi. accelerating at 3000 rpm Refrigerator exhibitor R-2230 psi to 20 psi Mini Split A-22 65 to 75PSI automotive R-12 35 psi. accelerating at 3000 rpm
