Abstract:
An absorption type refrigerating apparatus comprising:an evaporator for storing a refrigerant liquid;an absorber for storing an absorbent solution which includes an absorbent for absorbing a vapor of the refrigerant liquid generated in the evaporator;a regenerator for receiving and heating up a portion of the absorbent solution to extract the refrigerant vapor from the absorbent solution;a rectifier for rectifying the refrigerant vapor extracted in the regenerator;a condenser for condensing and feeding the refrigerant vapor rectified by the rectifier to the evaporator;a conduit for conveying a portion of the refrigerant vapor from the evaporator to the upper part of the rectifier for use as a vapor/liquid contact fluid in the rectifier;a temperature sensor for detecting the temperature of the refrigerant vapor rectified in the rectifier;a refrigerant liquid flow controlling means for increasing or decreasing the flow of the refrigerant liquid conveyed to the rectifier; anda controller responsive to a change in the temperature detected by the temperature sensor, which delivers a flow increase command to the refrigerant liquid flow controlling means when the temperature detected by the temperature sensor is higher than a reference temperature level and a flow decrease command to the refrigerant liquid flow controlling means when the temperature is not higher than the reference temperature level.
