Title:
ABSORPTION REFRIGERATOR, CONTROL PROGRAM, AND CONTROL METHOD OF ABSORPTION REFRIGERATOR
Document Type and Number:
Japanese Patent JP2018146190
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an absorption refrigerator, a control program, and a control method of the absorption refrigerator that determine whether it is necessary to dilute absorbent by appropriately performing the concentration calculation based on pressure.SOLUTION: An absorption refrigerator 1 for cooling or heating temperature control target fluid C in the absorption cycle of absorbent S and refrigerant V comprises: a regenerator 30 for heating absorbent solution Sw by a heating source 31 to release refrigerant Vg; a regenerator pressure correlation value detector 51 for detecting the pressure of the regenerator 30 or the physical amount with this correlation; a solution pump 19 for circulating the absorbent S inside; a refrigerant liquid mixable part 70 capable of switching the mixing/non-mixing of the refrigerant liquid Vf into systems 10, 18, 30, and 38 in which the absorbent S can circulate; and a control device 60 in which when stopping the absorption refrigerator 1, low heating operation is performed, and during this time, when the calculated concentration based on the value detected by the regenerator pressure correlation value detector 51 is less than a predetermined value, the control device stops the supply of the heating source 31 to the absorption refrigerator 1.SELECTED DRAWING: Figure 1
