で、太陽熱を効率良く利用できる。In the absorption refrigerating machine (hereinafter referred to as this machine) having such a configuration, the rare absorption liquid flowing in the outer tube (T 0 ) of the double-tube heat exchanger (Hex) is transferred by the solar heat collector (Cs). While being heated to generate refrigerant vapor, it reaches the separation chamber (Sep), where the refrigerant vapor and the concentrated absorbing liquid are separated. Then, the concentrated absorbent flows into the inner pipe (Ti), and while flowing down this inner pipe, the outer pipe (T
The temperature of the concentrated absorbent itself flowing to the absorber (A) is lowered by promoting the temperature rise of the rare absorbent in ( 0 ). In this way, in this machine, since the dilute absorption liquid and the concentrated absorption liquid are heat-exchanged in the double-tube heat exchanger (Hex), the solution heat exchanger used in the conventional absorption refrigerator. Can be omitted.
In addition, solar heat collectors (Cs) and double-tube heat exchangers (He
It is possible to utilize the radiant heat of sunlight by using a transparent material (for example, glass) for the outer tube (T 0 ) of x), and
Since the heat loss at the time of transmitting the solar heat to the absorbing liquid side is also reduced, the solar heat can be efficiently used.

Refrigerant vapor sent to the rectifier (R) is increased in purity here, and the refrigerant vapor (P
It reaches the condenser (C) via C) and is liquefied in this condenser. Then, the refrigerant liquid flows into the evaporator (E) via the throttle valve (V 2 ) to be vaporized, and the water in the chiller (19) is cooled. Note that brine other than water may be circulated in the circulation path (26). Further, the vaporized refrigerant is absorbed by the concentrated absorbing liquid flowing into the absorber (A). Then, the rare absorption liquid that has absorbed the refrigerant is sent to the rectifier (R) by the second pump (P 2 ),
Furthermore, by the first pump (P 1 ), double tube heat exchanger (Hex)

The refrigerant vapor is sucked in to accelerate the generation of the refrigerant vapor in the solar heat collecting type generator (G), so the absorbing liquid can be sufficiently concentrated even when the solar heat is insufficient, such as in rainy weather or cloudy weather. Can be generated, and good refrigeration performance can be exhibited. Also, since the flow rate of the refrigerant sent to the rectifier (R) and the decrease in temperature and pressure are prevented, the rectification capacity of the rectifier (R) is controlled by the temperature in the solar heat collector (Cs). Can be maintained in the same manner as before, and the purity of the refrigerant flowing into the evaporator (E) can also be maintained at a high level, and good refrigeration performance can be obtained.

る。Then, in this machine, when the amount of insufficient solar heat increases and the temperature inside the solar heat collector (Cs) further decreases, the compressor (COMP) operates with even greater power by the signal from the temperature detector (S). The refrigerant vapor that has been further heated and pressurized is sent to the rectifier (R), and the power of the compressor (COMP), that is, the operating capacity is controlled in accordance with the heat collection state of the solar heat collector (CS). (COMP) can avoid wasteful operation, and when the heat collection state deteriorates, the signal of the temperature detector (S) further increases the operation capacity of the compressor (COMP), increasing the purity of the refrigerant vapor. The refrigerant vapor can be stably sent to the rectifier (R) while being kept.

とができる。(G) Effect of the Invention As described above, in the absorption refrigerator of this type of the present invention, the operating capacity of the compressor is improved as the temperature detected by the temperature detector provided in the solar heat collector is decreased. , The unnecessary movement of the compressor can be avoided, the running cost of the absorption refrigerator can be reduced, and when the heat collection amount of the solar heat collector decreases and the temperature decreases, the refrigerant vapor sent to the rectifier due to this decrease. The power of the compressor is surely increased before the amount of heat is reduced to prevent insufficient concentration of absorption liquid (insufficiency of refrigerant) in the solar heat collector generator, and to prevent insufficient refrigerant flow rate and temperature and pressure drop. Since it is trying to prevent, it is possible to maintain the rectification capacity of the refrigerant in the rectifier and keep the purity of the refrigerant sent to the evaporator high.
In addition, the temperature of the absorbing liquid can be kept high, and the performance of this type of absorption refrigerator can be satisfactorily exhibited even in rainy or cloudy weather.

A generator provided with a solar heat collector for separating a refrigerant from an absorbing liquid by the heat collected from the solar heat collector, a rectifier, a separator, a condenser for enhancing the purity of the refrigerant separated by the generator, In an absorption chiller consisting of an evaporator and an absorber connected by piping, a double-tube heat exchanger is inserted into the solar heat collector, and one end of the outer tube and one end of the inner tube of this double-tube heat exchanger are respectively inserted. An inlet for the diluted absorbent that flows from the absorber through the rectifier and an outlet for the concentrated absorbent to the absorber are provided, and a separation chamber for the refrigerant and the absorbent is provided at the other end of the outer tube. The separation chamber is provided with an inlet for the concentrated absorbing liquid, which is formed by opening the other end of the inner pipe downward, and the refrigerant separated from the absorbing liquid in the separating chamber is connected to the rectifying device to the rectifying device. A compressor is installed in the middle of the flowing pipe, and the operating power of this compressor is installed in the solar heat collector. Absorption refrigerating machine characterized by detecting the temperature of the temperatures detector is controlled to increase with the decreasing.
