What are the normal high and low pressures for car air conditioning?
1 Answers
Car air conditioning normal high pressure should be 1.3-1.7MPa (13-17kg/cm2 or 190-250Lbf/in2); normal low pressure should be between 0.15-0.25MPa (1.5-2.5kg/cm2 or 20-35Lbf/in2). The following is the extended content: 1. The car air conditioning system is a device that cools, heats, ventilates and purifies the air in the compartment. It can provide a comfortable riding environment for passengers, reduce driver fatigue and improve driving safety. Air conditioning equipment has become one of the indicators to measure whether a car is fully functional. 2. In summer, when the temperature difference between the inside and outside of the car is large, it is not advisable to turn the air conditioning temperature too low immediately after entering the car. You can first use the high air volume natural wind to disperse the heat in the compartment, then do not close all the windows, turn on the air conditioning, and wait for the body to gradually adapt before adjusting the air conditioning to the desired temperature and closing the windows. In this way, the body will not be uncomfortable due to the sudden drop in external temperature. 3. The temperature of the air conditioning is not the lower the better. The most comfortable temperature for the human body is about 23 degrees Celsius. On sunny summer afternoons, the air conditioning should not be too low, which can not only resist the hot summer sun but also ensure that the ambient temperature of the human body is not too low, thereby avoiding "air conditioning disease", and also responding to the national call for energy saving, emission reduction, low carbon and environmental protection.
