The operation principle of apparatus of the present invention is as follows:
High temperature heat source 7 at first enters high temperature level absorption type refrigerating unit, adsorbent zeolite among heating absorber A4 or the B5, desorb evaporation from zeolite after cold-producing medium water is heated, enter condenser A1 by pipeline and valve, the liberated heat device A3 that is cooled takes away and is condensed into aqueous water, enter evaporimeter A2 then, evaporate behind the heat of the cold coal water of absorption external system.The water vapour that produces enters absorber A4 or B5 is adsorbed the absorption of agent zeolite, thereby finishes high temperature level kind of refrigeration cycle.Owing to 2 absorbers (A4 and B5) are arranged at this refrigeration unit, can realize adsorbing and the hocketing of desorption process by the time switch of by-pass valve control, guarantee the continuity and the backheat to each other of kind of refrigeration cycle and return matter, thus raising coefficient of performance COP.Experiment and studies show that zeolite-water conservancy project is verified still can reach the higher coefficient of performance under higher adsorption temp.
Flow into low temperature level double-effect lithium bromide absorption type refrigeration unit through the high temperature heat source after the cooling of absorption type refrigerating unit, lithium bromide water solution in the heating high-pressure generator 8, the cold-producing medium aqueous vapor that its mid-boiling point is lower changes into high-pressure water vapor, separate with the absorbent lithium bromide, the concentration of remaining lithium bromide water solution then can raise gradually.The high-pressure water vapor that high pressure generator 8 produces is passing through low pressure generator 9 and is emitting the laggard condenser B10 of the going into discharge liquid heat-transmission of part heat and condense into water.The water vapour that is produced by low pressure generator 9 then directly enters condenser B10 discharge liquid heat-transmission and condenses into water.Liberated heat was taken away by external cooler B14 when water vapour liquefied in condenser B10.HTHP condensate water among the condenser B10 becomes the low-pressure water with evaporating pressure through the choke valve decompression, inflow evaporator B15 then, the heat (realizing refrigeration) that absorbs external system also flashes to low pressure water vapor, enters absorber 13 then and is absorbed by the dense lithium bromide water solution from high pressure and low pressure generator and emit heat.Heat is taken away by external cooler B14.Lithium bromide water solution after the dilution sends into high pressure generator 8 after by solution pump 12 pressurization and low pressure generator 9 is heated once more, thereby finishes low temperature level double-effect lithium bromide absorption type kind of refrigeration cycle.
