Adsorption heat pump

An adsorption heat pump comprising:

• an evaporator configured to evaporate a refrigerant;
• and
• an adsorbent heat exchanger including an adsorption member configured to adsorb vapor evaporated by the evaporator, and a heat transfer tube in which a heating medium flows,
• wherein the adsorbent heat exchanger includes a pressing mechanism configured to press and compress the adsorption member depending on a temperature of the heating medium flowing inside the heat transfer tube, and
• wherein the heat transfer tube includes:
• an inlet manifold into which a heating medium flows;
• an outlet manifold out of which the heating medium flows;
• a plurality of branched tubes connected between the inlet manifold and the outlet manifold;
• first heat transfer plates each placed perpendicular to the branched tubes and connecting the branched tubes;
• and
• a second heat transfer plate placed parallel to the branched tubes and connecting the first heat transfer plates, and
• the pressing mechanism includes:
• a thermosensitive member fixed to the second heat transfer plate and designed to change in shape depending on a temperature of the heating medium flowing inside the branched tubes, the temperature being transferred to the thermosensitive member through the first heat transfer plates and the second heat transfer plate;
• and
• a pressing plate pressing the adsorption member, which is sandwiched between the pressing plate and a corresponding one of the branched tubes, toward the corresponding one of the branched tubes due to changing in shape of the thermosensitive member,
• when the temperature of the heating medium flowing inside the branched tubes is higher than a predetermined temperature, a pressing force against the pressing plate becomes larger due to changing in shape of the thermosensitive member, and the pressing plate moves toward the corresponding one of the branched tubes.
