<p><P>PROBLEM TO BE SOLVED: To prevent reduction of refrigerant spraying amount caused by refrigerant flushing in a refrigerant spraying device part of a plate-type evaporator in an absorption type refrigerating device free from a refrigerant circulation pump. <P>SOLUTION: In this absorption type refrigerating device comprising a generator 1 heating an absorption dilute solution to obtain refrigerant vapor and absorption concentrated solution, a condenser 3 for condensing and liquefying the refrigerant vapor supplied from the generator 1, an evaporator 4 for spraying the refrigerant liquid from the condenser 3 to a heat transfer plate face and evaporating the same, an absorber 5 for making the absorption concentrated solution from the generator 1 absorb the refrigerant vapor evaporated by the evaporator 4, and a solution pump 7 for supplying the dilute solution absorbing the refrigerant vapor by the absorber 5, to the generator 1, and spraying the refrigerant liquid from the condenser 3 to the heat transfer plate face of the evaporator 4, for evaporating the refrigerant without circulating the refrigerant, a refrigerant supply pipe from the condenser 3 is dipped in the refrigerant in a refrigerant reservoir in the spraying device for spraying the refrigerant onto the heat transfer plate face at an upper part of the evaporator 4, and the flowing-in refrigerant is cooled by the refrigerant of the refrigerant reservoir, thus temperature difference between the flowing-in refrigerant and saturated vapor of the evaporator 4 is reduced. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
