IPC: F25B49/04
Filed: 1995-08-03
Abstract: PROBLEM TO BE SOLVED: To perform an early sensing of abnormal state in an absorption freezer and prevent trouble in advance by a method wherein it is diagnosed that a crystal to be caused by super-cooling of absorption liquid is going to be generated when its temperature is lower than a specified super-cooling crystal-forming temperature after its heat exchanging with absorption liquid having a high concentration. SOLUTION: Although a state point is normally at a position of higher temperature than a super-cooling crystal temperature Tc, this state point is moved lower than a crystal forming line in the case that an excessive temperature reduction is produced in absorption liquid (b) having a higher concentration through heat exchanging at a heat exchanger 13 so as to produce a super-cooled crystal.  In this case, a temperature of the absorption liquid (b) having a higher concentration after cooling by the heat exchanger 13 is compared with a super-cooled crystal temperature Tc calculated in reference to an equation of Tc=-218.93+65.77×-0.4839×<2> (X is a concentration of the absorption liquid (b)), thereby when a temperature of the absorption liquid (b) becomes lower than the super-cooling crystallization temperature, it is diagnosed that there is geared that a crystal may occur due to super-cooling in the absorption liquid (b). Accordingly, it is possible to prevent trouble or operation suspension from occurring.
