<p><P>PROBLEM TO BE SOLVED: To improve performance by achieving a stable opening/closing operation of a valve in an adsorption type heat pump using a differential pressure drive type valve. <P>SOLUTION: The adsorption type heat pump 30 includes adsorbers 1, 2 adsorbing and desorbing a refrigerant 21, an evaporator 3 evaporating the refrigerant, a condenser 4 condensing the refrigerant, a first flow path 5 provided between the adsorber and the evaporator to allow a gas-phase refrigerant 21X to flow therein, a second flow path 6 provided between the adsorber and the condenser to allow the gas-phase refrigerant to flow therein, a first valve 10 provided in the first flow path to open and close the first flow path, and a second valve 11 provided in the second flow path to open and close the second flow path. At least one of the first valve and the second valve includes a valve element 31 opened and closed due to a differential pressure of the refrigerant of the gas phase, a valve seat 32, and a heating/cooling means 34 for heating or cooling the valve seat. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
