METHOD FOR INCREASING HEATING CAPACITY OF ABSORPTION- WATER COOLED/WARMER AND INCREASING LOAD ABSORPTION WATER COOLER/WARMER

摘要

PROBLEM TO BE SOLVED: To maintain the pressure of refrigerant steam in a high-temperature regenerator to atmospheric pressure or less by bypassing the refrigerant steam from the drain chamber of the low-temperature regenerator to an evaporator using a bypass pipeline with a gate valve. SOLUTION: A bypass pipeline 31 with a gate valve 32 as a valve means for closing down is provided between a drain chamber 2d of a low-temperature regenerator 2 and an evaporator 4. Refrigerant steam is bypassed from the drain chamber 2d to the evaporator 4 by the bypass pipeline 31, thus reducing the amount of generated refrigerant liquid in the low-temperature regenerator 2, hence suppressing the increase in refrigerant steam pressure in a high- temperature regenerator 1, and maintaining atmospheric pressure or less in heating increase operation for throwing an amount of heat that is at a rated value or higher in cooling operation for the high-temperature regenerator 1, without interrupting a function that is peculiar to an absorption water cooler/ warmer with a U-shaped sealing pipe 11 and a bubble pump 30.
