Abstract
A coldness generating apparatus comprising: an absorption type refrigerator having an evaporator for evaporating refrigerant, an absorber in which an absorbent for absorbing the thus-evaporated refrigerant steam is contained, a regenerator for heating and condensing the absorbent which has been diluted by the refrigerant steam, and a condenser for condensing and liquidizing the refrigerant steam which has been evaporated by heating and condensing the absorbent. A regenerating tank regenerates coldness generated by the evaporator, and the refrigerant comprises refrigerant having the solidification temperature lower than the freezing point so that coldness which is lower than the freezing point and which has been generated in the evaporator is regenerated in the form of ice or ice slurry. Since coldness can be regenerated at high density, cooling performance can be improved.
