In three-effect absorption-type refrigeration machine 58a, in Fig. 2, omit diagram and the closed circuit of absorption liquid is described successively.First, will absorb a large amount of refrigerant vapours at absorber place and rare absorption liquid of concentration being reduced form is carried from absorber to cryogenic heat exchanger under the effect of low temperature absorption liquid pump, utilize this cryogenic heat exchanger to heat, to cryogenic regenerator, carry afterwards.
At cryogenic regenerator place, the major part of the concentrated absorption liquid in the centre after low temperature backheat is absorbed in middle temperature under the effect of liquid pump and carries to mid temperature heat exchanger from cryogenic regenerator, utilize this mid temperature heat exchanger heat after to middle temperature regenerator conveying.Concentrated absorption liquid warm regenerator place in this, this centre carries out backheat, discharges and makes concentration further to raise a part for the cold-producing medium of absorption and become the concentrated absorption solution of high concentration.From the remainder of the concentrated absorption liquid in the centre of cryogenic regenerator, via the first bypass pipe, bypass is supplied to the concentrated absorption solution pipe arrangement returning to absorber.
From part or all of the concentrated absorption solution of middle temperature regenerator, at high temperature, absorb under the effect of liquid pump and carry to high-temperature heat-exchanging, at this, carrying out heat exchange and after being heated, to high temperature regenerator, supplying with the concentrated absorption solution from high temperature regenerator (in Fig. 2, Reference numeral 72).From the remainder of the concentrated absorption solution of middle temperature regenerator (can be zero situation), via the second bypass pipe, collaborate the absorption liquid pipe arrangement from the heated side of high-temperature heat-exchanging.
At high temperature regenerator place, the concentrated absorption solution after heating is concentrated is directed to the heated side of high-temperature heat-exchanging and the concentrated absorption solution from middle temperature regenerator is heated, and the heated side to mid temperature heat exchanger imports afterwards.From the remainder of the concentrated absorption solution of middle temperature regenerator (can be zero situation), via the second bypass pipe, collaborate the absorption liquid pipe arrangement from the heated side of high-temperature heat-exchanging.
Refrigerant vapour from high temperature regenerator imports via refrigerant vapour Guan Xiangzhong temperature regenerator, at this, absorption liquid is heated concentrated, afterwards cold-producing medium draining is imported to cryogenic regenerator.
