本発明は、吸収式ヒートポンプと冷腰兼用の吸収冷凍機
とからなる複合吸収冷凍機としての廃熱利用冷暖房装置
に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heating and cooling system using waste heat as a composite absorption refrigerator comprising an absorption heat pump and an absorption refrigerator that also serves as a cooling unit.
一般に、工場では、６０℃程度の温排水がある。Generally, factories have heated wastewater at a temperature of about 60°C.

廃熱利用の冷暖房装置に関する。The temperature of this heated waste water is sufficient for heating and hot water supply at the end of use, but it has no value when considering the temperature drop along the transport route from the discharge end to the end of use. In order for the water to be usable for heating, cooling, and hot water supply at the user end, it must be at a temperature level of 80 to 90 degrees Celsius or higher for hot water for heating and hot water supply, and 5 to 7 degrees Celsius for cold water for cooling at the discharge end. It is. In view of these points, the present invention
A heating and cooling system using waste heat that uses low-temperature (approximately 60 qo) heated wastewater discharged from factories to produce hot water for heating and picture baths, cold water or ice for air conditioning in combination with an absorption refrigeration cycle. Regarding.

を得る装置である。A heat pump using an absorption refrigeration cycle is a device that evaporates a refrigerant using heat pumped up from a low-temperature heat source such as heated waste water, and extracts high-temperature hot water using the reaction heat generated when this cold soot vapor is absorbed into an absorption liquid. Similarly, a refrigerator is a device that cools water using the heat of vaporization when cold soot evaporates to obtain cold water for air conditioning.

ようにしている。In addition, approximately 550 liters of water flows from the hot water source 11 through the outgoing pipe 14.
The heated waste water of 0 flows in parallel to the evaporator 4' and generator 1' of the absorption heat pump and the evaporator 4 of the absorption refrigerating machine, is discarded, and flows from the cooling water source 12 through the outgoing pipe 15. The cooling water (approximately 15 C) condenses and liquefies cold soot in the condenser 3' of the absorption heat pump, and then is refluxed or discarded through the cell tube 16, and is further converted into steam (approximately 160 C) in the boiler 10. The diluted absorption liquid in the generator 1 is heated, and the absorption refrigerator is driven while returning to the boiler 1 again. The absorption heat pump 9 and the absorption chiller 8 supplied with heated waste water, cooling water, and high-temperature fluid in this manner can heat the absorbers 2, 2' and the condenser 3 to 9000 or more, and the conduit 17 , 17', 18, 18' and the utilization end 13 is heated to 9000 °C;
At the usage end 13, it can be used for heating or hot water supply.

0) supply and extraction of high-temperature water (approximately 80°C), same as for heating. However, in the absorption refrigerator 8,
The high temperature water obtained from the absorption heat pump 9 is transferred to the pipe 17,
By circulating to this absorption refrigerator 8 via 17', 18, and 18', it is used as a heat source for the generator 1. In order to turn the gaseous refrigerant generated here into liquid cooling in the condenser 3 and to efficiently absorb the vaporized refrigerant in the evaporator 4, the absorption refrigerator 8 is connected to an outgoing pipe 15' from a cooling water source 12'. The cooling water that flows in through the absorber 2 and the condenser 3 is sent to the cooling water source 12'.
This allows the evaporator 4 to be cooled to below 0°C. Therefore, during the day, the pipes 19, 19
'The brine circulated between the utilization end 13 and the utilization end 13 through the
℃ and used for air conditioning, and at night, the amount of prine circulated through the evaporator 4 is reduced, and the low temperature circulation below zero degrees is used to make ice, etc., for storage cooling during the peak cooling load during the day. You can also donate.

ので割愛した。In addition, the absorption heat pump 9 for obtaining the temperature conditions as shown in FIGS. 3 and 4 is specifically shown by the imaginary line in FIG. 2 and the dotted figure number, It is necessary to connect similar absorption heat pumps in two stages, but in the description of the present invention, the details are omitted because they are not directly relevant.

かなえるものである。In this way, in the present invention, the boiler is used with the Okutaka switching type absorption refrigerator during heating, but this is to increase the operating rate of the equipment by operating the absorption refrigerator during heating as well. Conceptually, high-temperature water and hot water for heating in the winter and cold water for cooling in the summer can all be provided by low-temperature heated wastewater.
