Abstract
Whenever necessary, an operation for diluting an absorbing solution after the stop of the operation is unlimitedly enabled without increasing the size of an absorption refrigerating machine. For the dilution operation after the operation of the absorption refrigerating machine, a pipe line of a dilute solution circulating pipe KD is opened by a dilution valve VD. Thereby, a solution pump P1 and an absorber A can be directly connected through a circulating pipe K6. The operation of the solution pump allows circulating a low-concentration solution and facilitates the dilution of a high-concentration solution to a low concentration. Since this case has nothing to do with a pressure difference in a path, the dilution operation can be performed whenever necessary. Moreover, since it is unnecessary to deal with a pressure loss, it is not necessary to increase the height of the apparatus. Thus, there are no increase in the space for installation and no rise in the cost of the apparatus due to the large-sized refrigerating machine. Moreover, since the solution pump used in the normal operation can be used for the dilution operation, an additional pump for the dilution operation only is not needed. The dilution operation can be therefore performed at low cost.
