    1. An evaporator to which a heat exchange fluid is supplied, an evaporator / absorber, an absorber, a regenerator, a regenerator / condenser, a condenser, the inside of the condenser and the regenerator / condenser. A communication pipe for communicating with the inside, a refrigerant transfer pipe for transferring the refrigerant evaporated in the regenerator into the heat transfer pipe in the regeneration / condenser, and the refrigerant from the heat transfer pipe in the regeneration / condenser A refrigerant transfer pipe for transferring to the condenser, and a refrigerant transfer pipe for transferring the refrigerant from the condenser into the heat transfer pipe of the evaporator and the evaporator / absorber,
    A concentrated absorbent transfer pipe for transferring the concentrated absorbent separated in the regenerator into the absorber and the regeneration / condenser, and the concentrated absorbent from the regeneration / condenser in the absorber and the evaporator. A concentrated absorbent transfer pipe for transferring into the absorber, a rare absorbent transfer pipe for transferring a diluted absorbent diluted by absorbing the refrigerant in the absorber to the regenerator, and a refrigerant in the evaporator / absorber Rare absorption liquid transfer pipe for transferring the absorbed and diluted rare absorption liquid to the regeneration / condenser, and heat exchange fluid transfer pipe for transferring the heat exchange fluid into each heat transfer pipe in the absorber and the condenser In addition, while the heating cycle is in operation, the absorbent is circulated between the regenerator and the absorber, and the absorbent is circulated between the regenerator / condenser and the evaporator / absorber. And when the cooling cycle is operating,
    The refrigerant evaporated in the evaporator is directly transferred to the absorber, and the concentrated absorbent separated in the regenerator is transferred into the absorber through the regeneration / condenser. Absorption type heat source device.
