Abstract:
An absorption type cooling and heating apparatus having an evaporator for holding a refrigerant, an absorber for allowing an absorbent solution to absorb a refrigerant vapor generated in the evaporator, a regenerator for recovering the density of an absorbent in the absorbent solution by heating up to extract the refrigerant vapor from the absorbent solution, a refrigerant vapor passage for transferring the refrigerant vapor from the regenerator to a condenser, and the condenser for condensing the refrigerant vapor which is returned back to the evaporator, where in a cooling operation, a heat-pump heating operation, and a direct-burner heating operation can be performed selectively, said absorption type cooling and heating apparatus comprising:a first conduit for transferring the condensed refrigerant generated in the condenser to the evaporator; a second conduit for transferring the absorbent solution from the absorber to the regenerator; a branch conduit branched from the first conduit; and a switching device for selectively communicating the branch conduit to the second conduit.
