NOVELTY - The device has a controller i.e. electronic control unit (ECU) (8), for switching cooling operation for cooling a vehicle battery (11) and heating operation for heating the battery. Heat exchange is performed between an absorber (7) and outside of the absorber in the cooling operation. Heat exchange is performed between the absorber and a battery case (12) in the heating operation, where refrigerant is supplied to the absorber from an evaporator (6) and absorbing solution with high concentration, which is accommodated in a regenerator (2), is supplied to the absorber.    USE - Absorption type heat pump device for a hybrid vehicle i.e. hybrid car. Can also be used for an electrical vehicle.    ADVANTAGE - The device is designed such that a flow path, which is common for the cooling operation and the heating operation, is used as the flow path configured by a heat exchanger so as to realize simplification of configuration of the device and to save spaces in the device without using sorbent and without necessity of separately providing a device, which cools the sorbent. The battery case functions as an evaporator, and the battery functions as a heat source of the evaporator to use circulation action of the device in the cooling operation so as to continuously cool the battery. The absorber and the battery case are subjected to heat exchange to use circulation action of the device in the heating operation so as to continuously heat the battery. The device provides heat of branched flow path to a location, which is desired to be heated so as to rapidly heat target even in a case of low temperature of heat source immediately after starting moving of the vehicle. The device is designed such that reaction heat depends on difference between concentration of the absorbing solution, which flows out from the absorber and concentration of the absorbing solution, which is supplied to the absorber in the heating operation even in a case where energy is stored by concentration difference and the heat source is changed, thus suppressing fluctuation of cold heat to be generated to suitably control temperature of the battery regardless of state of the heat source, while improving cooling performance of the device.    DETAILED DESCRIPTION - The refrigerant is gas phase refrigerant i.e. vapor, or liquid phase refrigerant i.e. water.
