| Only very small amounts of water are soluble in liquid refrigerant. On the other hand, refrigerant vapour and water vapour mix in any proportion. |
| Any water present in the refrigerant circuit will be carried along as droplets. The dryer, dryer bag or dryer cartridge in the receiver or reservoir are capable of holding approx. 7 grams of water before they are full and cannot absorb any more water. If there is further water in the circuit, it will flow to the expansion valve jet or to the restrictor and becomes ice. |
| The air conditioning system will stop cooling. |
| Water destroys the air conditioner because at high pressures and temperatures it combines with other impurities to form acids. |
