Although most separators are two-phase in design separating the gas and liquids, they can be built three-phase to separate natural gas, liquid hydrocarbons, and free water.

Practice proved that design and apply the gas-liquid separator legitimately have a very important signification to improve the reliability of air conditioner product.

The results show that the values from this simplified calculation formula is consistent to the test data and it can be used to design the spiral structures.
