Title:
ADSORPTION REFRIGERATOR
Document Type and Number:
Japanese Patent JP2018155458
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To solve a problem that adsorption refrigerators operable even at a low heat source temperature and enabling improvement of a COP have not been provided so far.SOLUTION: An adsorption refrigerator includes: an evaporator for generating cold by vaporizing a liquefied refrigerant; a first adsorption reaction section for causing the vaporized refrigerant generated from the evaporator to adsorb to a first adsorbent while cooled and then desorb by heating; a second adsorption reaction section for causing the vaporized refrigerant generated from the evaporator to adsorb to a second adsorbent different from the first adsorbent while cooled and then desorb by heating; a compressor for compressing the refrigerant desorbed by the first adsorption reaction section and the second adsorption reaction section; a condenser for liquefying the refrigerant compressed by the compressor by cooling and then supplying the refrigerant to the evaporator; and a reuse flow passage for recovering adsorption heat by using fluid used for the cooling in the first adsorption reaction section and using the adsorption heat for heating for desorption in the second adsorption reaction section.SELECTED DRAWING: Figure 1
