| description | The invention provides an absorption type heat pump, which prevents crystallization of concentrated absorption solution due to partial load in the heating operation. A heat source water pump is disposed on the upper stream side of the heat conductive pipe through the evaporator, a flow detection mechanism is disposed on the lower stream side, a refrigerating temperature sensor is disposed on the bottom of the evaporator. When the flow of the heat water is reduced below the set value, or the heat pump stops, the operation is not immediately stopped for dilution operation of the absorbent liquid, so that crystallization of the concentrated absorption solution is prevented. Moreover, when the heat water is likely to freeze, the refrigerating temperature sensor measures the temperature of therefrigerant liquid accumulated at the bottom of the evaporator; when the temperature of the refrigerant liquid exceeds the set temperature, dilution of the absorbent liquid is carried out, which is stopped when the temperatur |
