of surfactants are added. In a conventional absorption refrigerator, the refrigerant, absorption liquid (LiBr), and surfactant are mixed in the absorber 34, and the absorption liquid (LiBr), refrigerant, and surfactant are separated in the regenerator 33.

On the other hand, the separation method using a centrifugal separator has the problem that the apparatus is large-scale and the cost of the apparatus itself is high. In addition, in conventional air-conditioning equipment, such as absorption refrigerators, the surfactant has a higher boiling point than the refrigerant, so it accumulates in the evaporator 32 without being evaporated, and the absorber 34, regenerator 33, and condenser 30 are sufficiently drained. Without circulation, these vessels 34
