Title:
CONTROLLING DEVICE FOR ABSORPTION TYPE REFRIGERATING MACHINE
Document Type and Number:
Japanese Patent JP3157349
Kind Code:
B2
Abstract:
PURPOSE: To prevent mainly a sudden lowering of a cold water outlet temperature by controlling the respective amounts of heating of a low-temperature heat source regenerator and a high-temperature regenerator on the basis of the cold water outlet temperature and also by controlling the operation and stop of the high-temperature regenerator likewise on the basis of a cold water inlet temperature.
CONSTITUTION: In an absorption type refrigerating machine, a low-temperature heat source regenerator 12 heating an absorption liquid and separating a refrigerant, a liquid condenser 13 for a low-temperature heat source condensing this refrigerant, a high-temperature regenerator 4 and a low-temperature regenerator 6 heating the absorption liquid and separating the refrigerant likewise, a condenser 7 condensing this refrigerant, an evaporator 1 cooling cold water by evaporation of the refrigerant and an absorber 2 sending the absorption liquid to the low-temperature heat source regenerator 12 are connected mutually by pipings. In this case, a cold water inlet temperature and a cold water outlet temperature of the evaporator 1 are detected by detectors S1 and S2 respectively. A controller 48 controls the respective amounts of heating of the low-temperature heat source regenerator 12 and the high-temperature regenerator 4 on the basis of the cold water outlet temperature and also controls the operation and stop of the high-temperature regenerator 4 on the basis of the cold water inlet temperature.
