WASTE HEAT UTILIZATION ABSORPTION TYPE REFRIGERATION SYSTEM AND ABSORPTION TYPE REFRIGERATOR

摘要

PROBLEM TO BE SOLVED: To provide a waste heat utilization absorption type refrigeration system and an absorption type refrigerator capable of reducing the possibility of an abnormal stop state of a power generator and more smoothly returning to rated operation while suppressing electric power consumption required for avoiding the abnormal stop state.;SOLUTION: In a waste heat utilization absorption type refrigeration system 1, a temperature of heat source water is raised by using cooling water of which temperature has been raised by cooling a power generator 10, and by using the heat source water, diluted solution is heated in a regenerator 21 of an absorption type refrigerator 20. The absorption type refrigerator 20 includes a concentrated solution bypass pipe 27 for guiding concentrated solution obtained by heating in the regenerator 21 to an absorber 24 without spraying the solution into an absorption heat transfer pipe 24a. A control panel 29 controls a ratio between the concentrated solution flowing without the concentrated solution bypass pipe 27 interposed and the concentrated solution flowing via the concentrated solution bypass pipe 27 by adjusting an opening of a control valve 28 in accordance with a temperature of cooling target fluid detected by a temperature sensor T in an operating state, so as to control absorption capacity of the absorber 24.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2018,JPO&INPIT
