本発明は吸収ヒートポンプにおける高効率廃熱
回収回路に関するものである。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a highly efficient waste heat recovery circuit in an absorption heat pump.

わち48％程度と低い廃熱回収率であつた。Conventional structure and its problems If the waste heat source is a fluid that cannot be directly introduced into the absorption heat pump, for example a corrosive fluid, a separate heat exchanger is installed and the waste heat is converted into water, which is then introduced into the absorption heat pump. However, conventionally, water, which is a medium, is simply circulated between the absorption heat pump and the heat exchanger, and the waste heat recovery rate is the same as when the waste heat fluid is directly introduced into the absorption heat pump. Regarding the type absorption heat pump, the waste heat recovery rate was as low as 0.48 in output heat per 1 waste emitted, that is, about 48%.

水である。 An example is shown in FIG. In the figure, 1 is a type absorption heat pump consisting of an evaporator 2 and an absorber 3, a regenerator 4 and a condenser 5, and 6 is a heat pump that uses circulating water (heat source) 7 that passes through the evaporator 2 and regenerator 4 as waste heat. fluid 8
9 is a heat exchanger that preheats by exchanging heat with the circulating water 7
It is a circulation pump that circulates. 10 is absorber 3
The temperature of the supplied water is raised in the absorber 3 and becomes the output fluid 11. 12 is cooling water passed through the condenser 5.

1152MCal／ｈとなり、廃熱回収率は1152／2400
＝0.48すなわち48％と低い回収率であつた。 For example, if there is a waste heat fluid 8 with a temperature of 110°C, a flow rate of 96 m 3 /h, and a calorific value of 2400 MCal/h, the feed water 10 with a flow rate of 32 m 3 /h and a temperature of 85°C is raised and lowered by the absorber 3 to 121 ℃ output fluid 11. Therefore, for the amount of waste heat of 2400MCal/h, the amount of heat extracted as output is 32 x (121-85) =
1152MCal/h, waste heat recovery rate is 1152/2400
= 0.48, or 48%, which was a low recovery rate.

取出される。 In FIG. 2, reference numeral 13 indicates water supply that is supplied to the circulating water 7 from the middle of the line;
The amount of circulating water of the preheated circulating water 7 and feed water 13 is then preheated by the heat exchanger 6, and the amount of circulating water is distributed to the evaporator 2 and regenerator 4 of the absorption heat pump 1.
The circuit configuration is such that the water is passed through the absorber 3 as a heating source, and the supplied water is passed through the absorber 3 of the absorption heat pump 1. Feed water 13 passed through absorber 3
receives absorbed heat, increases its temperature, and is extracted as an output fluid 14.

対し、出力として取出される熱量は40×（121−
85）＝1440MCal／ｈとなり、廃熱回収率は
1140／2400＝0.6すなわち60％（実験によると55
〜70％）と高い回収率を得られる。 Here, as in the conventional example, if there is a waste fluid 8 with a temperature of 110°C, a flow rate of 96 m 3 /h, and a calorific value of 2400 MCal/h, the feed water 13 with a flow rate of 40 m 3 /h and a temperature of 85°C is absorbed by the absorber 3. Output fluid 1 heated to 121℃
It becomes 4. Therefore, for a waste heat amount of 2400MCal/h, the amount of heat extracted as output is 40×(121−
85) = 1440MCal/h, and the waste heat recovery rate is
1140/2400 = 0.6 or 60% (according to experiment 55
A high recovery rate of ~70%) can be obtained.

収ヒートポンプ１の設備容量が小さくできる。 In addition, as an absorption heat pump equipment, this example is smaller than the conventional one. For example, the amount of heat exchanged in the absorber 3 is 40×(121-100)=840MCal/h, compared to the conventional 1152MCal/h. , the installed capacity of the absorption heat pump 1 can be reduced.

In this case, circulating water 7 is circulated between the evaporator 2 and heat exchanger 6 of the absorption heat pump 1, Separate steam 1 for vessel 4
5 is passed. Further, the feed water 13 is passed from the absorber 3 to the condenser 5. Even with such a configuration, a high heat recovery rate can be obtained.
