制御をしている。On the other hand, the refrigerant vapor from the high-temperature regenerator 14 enters the low-temperature regenerator 56, where it condenses and liquefies by heating the absorbing liquid and enters the condenser 54.
After the refrigerant vapor generated when the absorbing liquid is concentrated to the intermediate concentration enters the condenser 54 and is cooled and condensed by the cooling water, the refrigerant liquid (for example, water) enters the evaporator 50,
The condensed coolant water is sprayed by the coolant circulation pump 78 to the heat transfer tubes (through which water flows) of the evaporator 50 to obtain cold water. A cooling / heating switching valve 80 is in a closed state during the cold water operation. By opening the cooling / heating switching valve 80 and further stopping the supply of the cooling water to the absorber and the condenser, hot water can be obtained instead of the cold water. Conventionally, load fluctuations are the cold water (hot water) outlet temperature, the cold water (hot water) inlet / outlet temperature difference,
Judgment is made by detecting the cooling water inlet temperature, etc. Normally,
The temperature is controlled by detecting these temperatures and increasing or decreasing the heating heat source.

The temperature of the chilled water outlet is detected by the temperature sensor 82, and when the chilled water outlet temperature is too low, a part of the absorbing liquid is controlled to an appropriate flow rate by the flow control valve 84 through the absorbing liquid mixing pipe 86, and the evaporator 50 is controlled. To reduce the cooling effect by being mixed into the refrigerant liquid side in the inside, and at the same time, to suppress the evaporation of the refrigerant in the evaporator 50, thereby filling the refrigerant liquid pool portion, and allowing the refrigerant liquid or the absorbing liquid and the refrigerant liquid to mix. The mixed solution is caused to overflow toward the absorbing solution through the overflow pipe 90 to reduce the concentration of the absorbing solution during operation (operation cycle concentration). This allows
Crystallization of the absorbing liquid is less likely to occur, and it is possible to prevent the cooling water from being too cold. At the same time, the start / stop of the refrigerant liquid circulation pump 78 or the flow rate control of the refrigerant liquid flowing through the refrigerant liquid circulation pipe 92 (by a control valve, rotation speed control, etc.) is performed to make the cold water temperature control more effective.

温度を下げ、温水温度の上がり過ぎを防止する。In a chiller / heater using waste heat (exhaust gas), since the heat on the heating side is supplied with a constant amount with little fluctuation during normal operation, the regenerators 14 and 56 always evaporate the refrigerant. I have. Similarly, since the evaporated refrigerant is cooled and condensed in the condenser 54, the condensed refrigerant always flows in the refrigerant pipe 94. For this reason, even at the time of low load or low cooling water, the refrigerant in the refrigerant pipe 94 does not drastically decrease in flow rate or does not stop flowing, there is no possibility of freezing, and the flow of the refrigerant is hindered. There is no. In this embodiment, since this function is added, the conventionally required bypass control of the exhaust gas and the control by the pseudo load become unnecessary, and the economic effect of the user becomes large. On the other hand, even if the hot water temperature rises too much during the heating operation, it is assumed that there is no control on the waste heat (exhaust gas) side, and the refrigerant in the absorption chiller / heater and the absorption liquid from the absorption liquid mixing pipe 86 are separated. The concentration of the absorbing solution is reduced by mixing, and at the same time, the cooling water pump 40 (and / or the cooling tower fan motor 44) shown in FIG. To prevent the hot water temperature from rising too high.

After the absorption liquid is heated and concentrated, it is discharged from the chimney 22 via the manual damper 20a. When the remaining portion of the exhaust gas is exhausted or stopped, the entire amount of the exhaust gas is bypassed through the high temperature regenerator 14 through the manual damper 24a and discharged from the chimney 22 through the bypass pipe 26. Reference numeral 28 denotes a purging blower, which is connected to an exhaust gas supply pipe 30 at the inlet of the high-temperature regenerator 14 and is used for purging and cooling the high-temperature regenerator 14 at the time of stoppage and maintenance. On the other hand, the cold or hot water from the cold / hot water generator 12 is introduced into the cooling / heating load 16 and used for cooling or heating.
The water is circulated to the cold / hot water generator 12 by the cold / hot water pump 36. The cooling water from the cold / hot water generating section 12 is introduced into the cooling tower 38 and cooled, and then introduced into the cold / hot water generating section 12 by the cooling water pump 40. The black painted manual valve is normally closed and used during maintenance. As described above, in the present embodiment, there is an advantage that the bypass control by the automatic damper and the control by the pseudo load (see FIG. 5) which are conventionally required are unnecessary.

さらに熱効率の向上、用途の拡大を図ることができる。As described above, the present invention has the following effects. (1) During cooling operation, the chilled water outlet temperature is detected by a temperature sensor, and if the chilled water outlet temperature is too low,
While controlling a part of the absorption liquid of the absorber through the absorption liquid mixing pipe to the appropriate flow rate by the flow control valve, it is mixed with the refrigerant liquid in the evaporator to raise the temperature of the chilled water outlet to reduce the cooling effect, and at the same time reduce the cooling effect. The evaporation of the refrigerant inside is suppressed, the refrigerant liquid reservoir becomes full, and the refrigerant liquid, or the mixed liquid of the absorption liquid and the refrigerant liquid overflows into the absorber through the overflow pipe, and the operation during operation is performed. Since it is configured so that the concentration of the absorbent (operating cycle concentration) can be reduced,
An operation trouble due to the crystallization of the absorbing liquid is less likely to occur, and the cold water can be reliably prevented from being too cold. (2) During the heating operation, the hot water outlet temperature is detected by the temperature sensor, and if the hot water outlet temperature is too high,
The refrigerant liquid and the absorbing liquid are mixed to lower the concentration of the absorbing liquid, and at the same time, the cooling water pump 40 (or / and the cooling tower fan motor 44) is started and stopped, and the pressure in the absorber and the absorption liquid are controlled by the cooling water. By lowering the temperature, overheating can be reliably prevented. (3) In absorption-type water heaters / chillers utilizing waste heat (exhaust gas), heat (exhaust gas) on the heating side is supplied without being controlled, and in normal operation, there is little large fluctuation and almost constant amount of heat Is supplied, the refrigerant is always evaporated in the high-temperature regenerator and the low-temperature regenerator. For this reason, in the condenser,
Since the evaporated refrigerant is always cooled and condensed, the condensed refrigerant always flows in the refrigerant pipe from the condenser.
Therefore, even at the time of low load or low cooling water, the refrigerant in the refrigerant pipe does not decrease in flow rate or stop flowing, and there is no possibility of freezing, so that the flow of the refrigerant is not hindered. . (4) According to the above (1) to (3), the bypass control of the exhaust gas and the control by the pseudo load which are conventionally required become unnecessary, and the cost can be reduced. (5) Since waste heat (exhaust gas) from the source of combustion waste heat is introduced into the high-temperature regenerator to heat and concentrate the absorbing solution, the retained heat of the waste heat (exhaust gas) is sufficiently recovered.・ The thermal efficiency is improved when used, which can greatly contribute to the expansion of applications, and the high-efficiency operation of absorption chillers / chillers becomes possible. (6) When a gas turbine is used as a combustion waste heat generation source and cold water obtained from an evaporator of a waste heat utilizing absorption chiller / heater is used for cooling the intake of the gas turbine,
Further, it is possible to improve the thermal efficiency and expand the application.
