| Only very small amounts of water are soluble in the refrigerant. On the other hand, refrigerant vapour and water vapour mix in any proportion. |
| Any water present in the refrigerant circuit is transported in drop form. The desiccant or drying cartridge present in the reservoir can absorb up to approx. 7 grammes of water. After absorbing this quantity the desiccant is saturated and cannot hold any more water. If any water remains in the refrigerant circuit, it will flow to the nozzle of the expansion valve or throttle valve and freeze. |
| The air-conditioner will then stop cooling. |
| Water destroys the air conditioner because at high pressures and temperatures it combines with other impurities to form acids. |
