Abstract
An air conditioning unit is capable of preventing a liquid absorbent from crystallizing, thereby enhancing reliability of the operation thereof. A given amount of refrigerant is supplied to dilute the liquid absorbent when the air conditioning unit stops in operation, and it is circulated in lines and components of the air conditioning unit, thereby cleansing the liquid absorbent remaining in the components or lines, and the liquid absorbent is returned to the liquid tank, so that the liquid absorbent is prevented from crystallizing, whereby reliability of the operation is enhanced.
