In an absorption system, where does the refrigerant boil?

In an absorption system, the refrigerant boils in the evaporator. This is where the low-pressure refrigerant absorbs heat from the environment, causing it to evaporate and transition from a liquid to a gas. The process of boiling occurs as the refrigerant takes in heat, which allows the refrigerant to effectively cool the designated area.

In contrast, the absorber is where the refrigerant vapor is absorbed by a secondary fluid, typically a solution, that facilitates the removal of the heat from the refrigerant. The condenser, on the other hand, is responsible for cooling and condensing the refrigerant gas back into a liquid state after it has absorbed heat. The generator is where the absorption solution is heated to drive off the refrigerant and returns it to the evaporator. Therefore, the boiling of the refrigerant, which is crucial for the cooling process, takes place in the evaporator.
