PROBLEM TO BE SOLVED: To provide a second type absorption heat pump which uses geothermal heat as heating thermal source, and to provide an agriculture facility and a heating method using the second type absorption heat pump.SOLUTION: A second type absorption heat pump 1 comprises: an evaporator 2; an absorber 3; a regenerator 4; and a condenser 5, and therein, has a thermal output that a temperature of a medium T to be heated becomes higher than the temperature of a heating medium H to be introduced to the evaporator 2 or the regenerator 4. Further, the second type absorption heat pump includes an atmosphere heat exchanger 6 which has a path of a cooling medium C for cooling the refrigerant vapor Rg of the condenser 5 and cools the cooling medium C with the air A and a geothermal heat exchanger 7 which has a path of heating medium H for heating refrigerant liquid R of the evaporator 2 and heating an absorption dilute solution Sd of the regenerator 4 and heats the heating medium H with geothermal heat Gh.
