摘要： PROBLEM TO BE SOLVED: To prevent freezing due to super-cool in an evaporator and permit the continuation of cooling operation without interrupting the same, even under a condition that a feed water temperature is low and the temperature of circulating cooling water is also low upon starting the cooling operation in an absorption type cooling and heating machine.
SOLUTION: The temperature of cooling water is detected by a cooling water thermistor upon starting cooling operation. When the detected temperature is determined as lower than a predetermined temperature (25°C for example), a cooling tower fan for a cooling tower is stopped. According to this operation, an excessive absorbing capacity of an absorber is prevented by stopping the circulation of the cooling water whereby the freezing of the evaporator is prevented and the cooling operation is effected without causing any trouble. Further, when the temperature of cooling water has become higher than 28°C, for example, after stopping the cooling tower fan, the operation of the cooling tower fan is re-started.

摘要： PROBLEM TO BE SOLVED: To solve the problem of uncertainty in setting up an air conditioner, i.e., the problem that no trial cooling operation can be performed in setting up the air conditioner to confirm its operation in a temperature condition where the trial cooling operation is supposed to be suspended (due to possible freezing of refrigerant in an absorption refrigerating cycle).
SOLUTION: When a command to perform a trail cooling operation is given in the conditions where there is a possibility for the refrigerant to freeze in the refrigerating cycle 7 (the outside air temperature is lower than 15°C), and where there is no possibility for cooling water to freeze in a water supply means 65 and cooling water piping 62 (the outside air temperature is 3°C or more), heating operation is performed to heat cooling water, followed by performing the trial cooling operation. Specifically, in such a procedure, pressure lowering in an evaporation/absorption case 41 is suppressed, and thus freezing of the refrigerant is prevented, so that the trial cooling operation is enabled. Thus limitation of the trial cooling operation can be so much raised as to remarkably enhance reliability in setting up an air conditioner, in comparison with a conventional air conditioner.

摘要： PROBLEM TO BE SOLVED: To prevent the supercooling of an evaporator and eliminate the trouble in cooling operation, when a load from the side of an indoor terminal machine is very small upon cooling operation and cooling operation stopping process or the like during the cooling operation, or when cold start is effected under a condition that a feed water temperature is low, in an absorptive cooling and heating machine.
SOLUTION: The temperature of the evaporator 4 is detected by a first thermistor Tf upon cooling operation and cooling operation stopping process or the like during the cooling operation. The temperature of the evaporator 4 is judged based on an output from the first thermistor Tf whether the same is lower than 3°C or not. When the temperature is lower than 3°C, both or either one of a cooling tower fan S or a cooling water pump P2 is stopped. When the temperature of the evaporator 4 is raised to a value higher than 7°C, the operation of both or either one of the cooling tower fan S or the cooling water pump P2 is re-started. According to this method, the supercooling and freezing of the evaporator 4 is prevented whereby the cooling operation is continued without interruption.

摘要： PROBLEM TO BE SOLVED: To solve the problems with a conventional absorption air conditioner that the life of a cold/warm water pump drops and the time required for automatic water filling operation becomes long because the fluctuation of water level within a cistern is large and the cold/warm water pump repeats the operation and stoppage many times when the automatic water filling operation for filling cold/warm water in a vacant cold/warm water pipe is executed.
SOLUTION: A controller is provided to continue the state of supplying water into the cistern 55, opening a cistern water supply valve 58 for a specified time (for five seconds), even if a high liquid level sensor 55a detects high water level. Thereupon, the time of cold/warm water pump 54 pressurizing and supplying cold/warm water into the cold /warm water pipe 53 during water supply increases. Hereby, the number of times of the water level within the cistern 55 dropping decreases, so the time required for automatic water filling operation can be shortened. Moreover, since the number of times of the water level of the cistern 55 dropping decreases, the number of times of the cold/warm water pump 54 repeats the operation and stoppage decreases, and the life of the cold/ warm water pump 54 elongates.

摘要翻译：要解决的问题为了解决传统的吸收式空调的问题，冷/热水泵的使用寿命下降，自来水灌装运行所需的时间变长，因为水箱内的水位波动大，冷/热水泵在空置冷/热水管道中灌装冷/暖水的自动灌水作业时，冷/热水泵重复操作和停机多次。解决方案：即使高液位传感器55a检测到高水位，也提供控制器以继续向储水箱55供水的状态，打开水箱供水阀58一段规定时间（五秒钟）。因此，在供水期间冷/暖水泵54对冷/暖水管53进行加压供水的时间增加。因此，水箱55内的水位下降次数减少，所以可以缩短自动充水运转所需的时间。此外，由于水箱55的水位下降次数减少，所以冷/暖水泵54的次数重复，停止运转减少，冷/暖水泵54的寿命延长。

摘要： PROBLEM TO BE SOLVED: To solve the problem of a usual indiscriminate diluting operation for a cooling operation conducted after recovery of power when the cooling operation is executed on the occasion of a power failure, considering that there are various cases in the state of the operation at the power failure and therefore the indiscriminate dilution causes waste.
SOLUTION: When power recovers in the case of the power failure in the course of the cooling operation, a means for the diluting operation mounted on a controller executes a simple diluting operation when the temperature of a high-temperature regenerator 15 which is stored at the power failure is below 60°C. When this temperature is 60°C or above, simulated cooling is executed according to the condition and the diluting operation is conducted. A useless diluting operation is held down consequently and crystallization can surely be prevented. Since the dilution is conducted by executing the simulated cooling operation according to the condition, an absorbing solution in an absorption type refrigerating cycle 7 can be circulated efficiently and, as the result, a dilution time can be shortened.
