一、序言吸收器是溴化锂吸收式制冷机的重要部件,制冷量与吸收量成正比,而吸收量又与传质推动力成正比。吸收器中吸收剂与水的质量交换可认为是由容器内的压差所引起的,这压差即吸收器上方的压力P_a~’和一定温度、浓度时溶液的蒸汽分压P_a之差。 First, the preamble Absorber is an important component of lithium bromide absorption chiller, cooling capacity and absorption is proportional to, and absorption and mass transfer is proportional to the driving force. The mass exchange of the absorbent with water in the absorber can be thought of as being caused by the pressure difference in the container which is the difference between the pressure P_a ~ ’above the absorber and the partial pressure of steam P_a at a given temperature and concentration.
