HEAT EXCHANGING UNIT, REFRIGERATOR, AND METHOD FOR CONTROLLING REFRIGERATOR

PROBLEM TO BE SOLVED: To provide a heat exchanging unit and a refrigerator capable of reducing size and weight and reducing costs by simplifying a structure.SOLUTION: A heat exchanging unit includes: a heat medium storage part 25 for storing a heat medium; an adsorbent storage part 33 communicated with the heat medium storage part 25 to store an adsorbent 32 capable of adsorbing and desorbing the heat medium; a first passage 3 disposed adjacently to the heat medium storage part 25 to enable selective flowing of cold raw water cooled by evaporated latent heat of the heat medium and cooling water for adding condensed latent heat to the heat medium; and a second passage 4 disposed adjacently to the adsorbent storage part 33 to enable selective flowing of hot water for heating the adsorbent 32 during desorption of the heat medium and cooling water for cooling the adsorbent 32 during adsorption of the heat medium. The adsorbent storage part 33 includes a pair of side faces, and the second passage 4 is formed including the side faces of the adsorbent storage part 33.
