量センサＳ１が出力する液量情報に基づいて、流量制御
弁Ｖ１が制御器Ｃにより制御される。In the absorption heat pump apparatus according to the present invention, the flow rate control valve V1 is controlled by the controller C based on the liquid amount information output from the liquid amount sensor S1 including a float switch provided on the evaporator 1.

再生器１などで冷媒が不足し、吸収液の濃度が異常に高
まって吸収液が結晶化すると云った不都合が起こること
がない。That is, the opening degree or opening / closing of the flow control valve V1 is controlled by the controller C so that the amount of the refrigerant liquid inside the evaporator 3 is within a predetermined range. Therefore, there is no problem that the refrigerant runs short in the regenerator 1 or the like during operation, and the concentration of the absorbing liquid abnormally increases and the absorbing liquid crystallizes.

る。When the operation is stopped, the controller C opens the on-off valve V2, returns the refrigerant liquid in the evaporator 2 to the absorber 4, and regenerates the absorbing liquid having a reduced absorbing liquid concentration. It is also supplied to the vessel 1 to prevent crystallization of the absorbing liquid.

もなっている。Further, in the controller C, the temperature of the absorbent supplied from the regenerator 1 to the absorber 4 via the absorbent pipe 11 is too high, or the controller C supplies the absorbent 4 to the absorber 4. If the temperature difference between the temperature of the absorbing liquid and the temperature of the used hot water (cooling water) flowing out of the heat transfer pipe 2A by cooling the refrigerant in the condenser 2 is too large, the absorbing liquid is concentrated too much in the regenerator 1 or the like, and the When the temperature of the absorbing liquid reaches a predetermined temperature or the temperature difference reaches the predetermined temperature difference, the on-off valve V
2, the refrigerant liquid in the evaporator 2 is returned to the absorber 4,
The concentration of the absorbing solution is reduced to prevent crystallization of the absorbing solution.

もなっている。Further, the controller C determines whether the temperature of the absorbent returned to the regenerator 1 by the absorbent pump P1 from the absorber 4 via the absorbent pipe 12 is too high,
Even if the temperature difference between the temperature of the absorbing liquid returned to the regenerator 1 and the temperature of the absorbing liquid evaporating the refrigerant and returning to the reservoir is too large, the absorbing liquid is crystallized in the regenerator 1 or the like. When the temperature of the absorbing liquid reaches a predetermined temperature or the temperature difference reaches the predetermined temperature difference, the on-off valve V
2, the refrigerant liquid in the evaporator 2 is returned to the absorber 4,
The concentration of the absorbing solution is reduced to prevent crystallization of the absorbing solution.

が結晶化すると云った不都合が生じることはない。Since the regenerator 1 and the condenser 2 are connected via the overflow pipe 19, the control of the flow control valve V1 and the opening / closing valve V2 by the controller C is not performed normally. However, since the excess refrigerant liquid in the condenser 2 is returned to the regenerator 1 through the overflow pipe 19, the amount of refrigerant liquid accumulated in the condenser 2 is limited. Therefore, there is no problem that the absorbent is excessively concentrated in the regenerator 1 or the like, and the absorbent is crystallized.
