(1) Use the working heat source (such as water vapor, hot water and gas, etc.) to heat the solution with a certain concentration conveyed by the solution pump from the absorber in the generator, and make most of the low-boiling refrigerant in the solution evaporate out.
(2) The refrigerant vapor enters the condenser, and is condensed into refrigerant liquid by the cooling medium, and then depressurizes to the evaporation pressure through the throttle.
(3) The refrigerant enters the evaporator through the throttle, absorbs the heat in the cooling system and intensifies into the refrigerant vapor under the evaporation pressure.
(4) In the generator A, the remaining solution (high boiling point absorbent and A small amount of unevaporated refrigerant) is reduced to the evaporating pressure through the absorbent throttle and enters the absorber at the evaporating pressure. It mixes with the low-pressure refrigerant vapor coming out of the evaporator, and absorbs the low-pressure refrigerant vapor and returns to the original concentration.
(5) The absorption process is often an exothermic process, so it is necessary to use cooling water in the absorber to cool the mixed solution. The concentration of the solution recovered in the absorber is boosted by the solution pump and then sent to the generator for further circulation.
