Problems solved by technology
Therefore, when the temperature of waste water drops, the efficiency of providing waste heat also drops
When the temperature of the residual hot water is lower than the temperature of the solution in the chiller, the heat will flow back from the solution to the residual hot water. Therefore, the serious problem is that the cooling capacity of the absorption chiller is insufficient.

Embodiment Construction
[0138] The best way to practice the invention
[0139] Next, preferred embodiments of the present invention will be described with reference to the accompanying drawings.
[0140] First, describe Figure 1 to Figure 17 Example shown.
[0141] figure 1 Shows the first embodiment of the present invention. The reference numeral 20 (20A-20K) indicating the whole device is an absorption cold and hot water machine. Next, the absorption chiller and hot water machine 20 (20A-20K) will be described.
[0142] In order to provide waste heat from the waste heat pipeline 2 to the absorption cold and hot water machine 20 (20A-20K), a waste heat supply line L2 is provided, and a heat exchanger 32 (32A-32K) is connected to the waste heat supply line L2. The waste heat of the hot and cold water machine utilizes the absorbing solution flowing in the system to provide the heat contained in the liquid.

The invention provides an absorption water chiller-heater and a method for controlling the absorption water chiller-heater, which can prevent the crystalline polamer from occurring inside a heat exchanger. The heat exchanger is connected with pipelines for utilizing surplus heat and receives the surplus heat supplied from the exterior. The invention can prevent the temperature of a high-temperature generator from raising and the corrosion which is caused by the raising temperature, and can not shapely decline the capacity of the absorption water chiller-heater. Under the condition that no ineffectual refrigerant is produced, the absorption water chiller-heater can prevent the temperature of the high-temperature generator from raising and the corrosion which is caused by the raising temperature, and can not shapely decline the capacity of the absorption water chiller-heater. In the absorption water chiller-heater and the control method thereof provided by the invention, the absorption water chiller-heater comprises a high-quality fuel system and a surplus-heating utilized system and is connected with the heat exchanger that supplies the surplus heat that is supplied from the exterior into a pipe of the surplus-heating utilized system. The invention is characterized in that the method detects the signals of yielding a solution terminating pump or running a burner in a detection device for operation termination, determines whether schedule time is missed a timing device after the detection while the schedule time is measured from the beginning of running the solution terminating pump and the burner and after the schedule time, and outputs control signals in a control device to a branching device and leads a fluid containing surplus heat to pass through the heat exchanger.
Description
technical field [0001] The present invention relates to an absorption chiller or absorption chiller and its control method (in this specification, so-called absorption chiller includes absorption chiller), wherein a high-quality fuel system and The waste heat utilization system is also equipped with a heat exchanger, which provides waste heat from the outside to the heat exchanger, and transmits the waste heat to the pipe of the waste heat utilization system through the heat exchanger. Background technique [0002] The Japanese patent application (Application No. 6-73428) previously filed by the present inventor discloses an absorption cold and hot water machine or an absorption refrigerating machine, which includes a high-quality fuel system and a waste heat utilization system and a heat exchanger. Provide the waste heat to the heat exchanger, and transfer the waste heat to the pipe of the waste heat utilization system through the heat exchanger. [0003] Here, there may b...
