| Distribution of the components of the refrigerant circuit and their influence on the high- and low-pressure side |
| On the high-pressure side, the condenser as well as the fluid reservoir are present and as a separation from the HP liquid side and the LP liquid side, the throttle or the expansion valve is present. |
| The high pressure arises from the fact that the throttle valve or the expansion forms a constriction and the refrigerant dams, this leads to a pressure and temperature increase. |
| Too much high pressure arises if too much refrigerant or refrigerant oil is poured in, the condenser is dirty, the radiator fan is defective, a blockage is present in the system or if humidity is in the refrigerant circuit (icing of the throttle or the expansion valve). |
| On the low-pressure side are located, the evaporator, the temperature sensor - evaporator and as a separation from the HP gas side and the LP gas side, the AC compressor. |
| A pressure drop in the system can occur through refrigerant loss, through the throttle or expansion valve (constriction not given), the AC compressor which is defective or the evaporator which is iced up. |
