In addition, in the conventional generator, when the operation is stopped, a part of the farm solution separated from the rare solution is left in the upper holder 41, and the farm solution remaining in the upper holder 41 is precipitated as a crystal, and the farm solution. As the concentration of was increased, the refrigerant vapor was not absorbed more by the absorber, and the efficiency of cooling and heating was lowered due to the decrease in absorption efficiency.

That is, in the conventional absorption type air conditioner generator, a portion of the solution is supplied to the condenser to reduce the safety of the system, and when the system is stopped, the farm solution precipitates as crystals, which lowers the efficiency of heating and cooling. there was.

In the drawing, reference numeral 50 denotes an evaporator, which evaporates the refrigerant liquid condensed in the condenser 40.

Next, the effect of the evaporator of the absorption type air conditioner according to the present invention configured as described above will be described.

First, when the system is operated, the refrigerant vapor is absorbed into the concentrated solution in the absorber 60 and converted into the rare solution. The rare solution converted by the absorber 60 is guided to the rare solution tube 90 to generate the generator ( 10 is supplied to the lower reservoir (12).

In addition, when the rare solution is continuously supplied to the lower reservoir 12, the rare solution is supplied into the nutrient solution tube 14, and heat is generated from the heat generating means 11 by a control signal of a control means (not shown). Is generated.
