A heat pump method and system with a pair of solid adsorbent beds connected to a heat pump loop and a reversible heat transfer loop. The heat transfer loop has a heater connected between one end of the beds and a cooling heat exchange connects the other end of the beds so that a heat transfer fluid flowing around the heat transfer loop heats one bed and cools the other.

A method of operating a heat pump system including a heat pump loop and a heating loop where the heat pump loop includes a pair of solid adsorbent beds connected to a condenser and an evaporator with an expansion device therebetween so that refrigerant flows from the bed being heated to the condense

A method of operating a heat pump system including a heat pump loop and a heating loop where the heat pump loop includes a pair of solid adsorbent beds connected to a condenser and an evaporator with an expansion device therebetween so that refrigerant flows from the bed being heated to the condenser while the refrigerant can flow from the evaporator to the bed being cooled, and where the heating loop includes a heat exchanger associated with each bed design so that when a heat transfer fluid is flowing therethrough, a thermal temperature gradient or wave will be generated along the bed together with a cooling heat exchanger between one of the ends of the beds and a heating means between the other ends of the beds comprising the steps of: circulating the heat transfer fluid around the heating loop until the exit temperature of the heat transfer fluid passing out of either of the beds shifts from the initial temperature of that bed by at least about twenty percent (20%) of the difference between the initial bed temperature and inlet fluid temperature; and then reversing the flow of the heat transfer fluid around the heating loop each time the exit temperature of the heat transfer fluid passing out of either of the beds shifts from the initial temperature of that bed by at least about twenty percent (20%) of the difference between the initial bed temperature and inlet fluid temperature.
