● Water is evaporated to create cold water. In a container (evaporator) with pressure close to a vacuum, when water is flowed through a heat transfer pipe that is in contact with the evaporating liquid, the heat from the flowing water is absorbed due to the latent heat of vaporization, resulting in a lower temperature (cold water) than the water that entered the pipe. When water is dripped onto the pipe in a vacuum, the water on the surface absorbs heat from the water inside the pipe and evaporates, thus producing cold water.

●The evaporated water vapor is collected. The water vapor (refrigerant) that evaporates in the evaporator is absorbed by the absorbent liquid in the absorber. The absorbent liquid (lithium bromide solution) that easily absorbs water vapor absorbs the incoming water vapor (refrigerant), causing the concentration of the absorbent liquid to become diluted.

● We create water vapor and a concentrated solution. The water vapor is absorbed by the absorber, and the diluted absorbent solution is sent to the regenerator. Using the principle of cooking in a pot, by heating the diluted solution, we evaporate the moisture (refrigerant) and return it to a high-concentration lithium bromide solution (absorbent solution that easily absorbs water vapor).

●Steam is cooled to create water. The water vapor (refrigerant) evaporated in the regenerator is sent to the condenser. When the water vapor (refrigerant) comes into contact with the pipes carrying cooling water, it condenses back into water (liquefaction). The resulting water (refrigerant) is sent back to the initial evaporator.
