2. Description of Related Arts
Under the premise that the heat pump can promote the residual heat temperature to the needed level of the user, adopting the absorption heat pump (AHP) technology to develop residual heat can bring a better energy conservation, environmental protection and economic interest. Promoting the heating temperature of the heat pump, using the lower temperature of the waste heat resources and improving the utilization rate of the waste heat resources are the main directions of people's efforts.
To get a higher heating temperature and performance index of the AHP, people explored several different effects and different stages units at first and different heat pump processes are compounded by many ways such as adding the heating-side, increasing the process of heating and so on. Then they got more meticulous effects and stages which are corresponding to the corresponding performance index. However, these single-effect or single-stage units own some deficiencies that each single-effect or single-stage units has the right work parameter and performance index just in a particular situation. For example, a single two level units has a high heating temperature while its performance index is low.
Seeing from the internal process of the units, the key to improve the heating temperature of the second-type absorption heat pump is to enhance the export solution concentration of the absorber. That means to promote the export solution concentration of the generator. It can improve the heating temperature of the corresponding units by using the recuperative principle to the generation-absorption process of the solution, establishing the recuperative generation-absorption system and compounding with different effects and different stages units. At the same time, adopting the way of recuperative heat can realize two-terminal heating or multiterminal heating of the second-type absorption heat pump which is useful for improving the performance index of the units.
An main object of the present invention is to provide a recuperative generation-absorption system of solution tandem cycle and a recuperative generation-absorption system of solution independent loop at first, then add some components in the two recuperative generation-absorption systems to gain the second-type absorption heat pump with a higher heating temperature which can be called the recuperative second-type absorption heat pump too. The specific contents of the present invention are described as follows.
1. One of the recuperative generation-absorption systems in this invention is the solution tandem cycle recuperative generation-absorption system which can be mainly formed by the generator, the first absorber, the second absorber, the first solution heat exchanger, the second solution heat exchanger, the steam bleeding chamber, the first solution pump, the second solution pump or plus the third solution pump.
The concentrated solution pipe of generator passes through the first solution pump, the first solution heat exchanger and the first absorber and then connects the steam bleeding chamber. The concentrated solution pipe of the steam bleeding chamber passes through the second solution pump, the second solution heat exchanger and then connects the second absorber. The dilute solution pipe of the second absorber passes through the second solution heat exchanger, the third solution pump if the system has it and then connects the first absorber. The dilute solution pipe of the first absorber passes through the first solution heat exchanger and then connects generator.
Generator has the pipe of residual heat medium or the pipe of thermal driving medium and the channel of refrigerant vapor which separately connect external. The first absorber has the pipe of heated medium and the channel of refrigerant vapor which separately connect external. The second absorber has the channel of refrigerant vapor and the channel of heated medium which separately connect external. The steam bleeding chamber has the channel of refrigerant vapor which connects external.
The dilute solution of generator is heated by the residual heat medium or the thermal driving medium and releases refrigerant vapor. The concentrated solution of generator flows through the first solution pump, the first solution heat exchanger, the first absorber in which it absorbs heat and a part of it is vaporization and then enters the steam bleeding chamber which releases refrigerant vapor. The concentrated solution pipe of the steam bleeding chamber flows through the second solution pump, the second solution heat exchanger and then enters the second absorber in which it absorbs the refrigerant vapor coming from outside the system and releases heat to the heated medium at the same time.
The dilute solution of the second absorber flows through the second solution heat exchanger, the third solution pump if the system has it and then enters the first absorber in which it absorbs the refrigerant vapor coming from outside the system and heats up the solution which flows through the first absorber and meets the heat demand of heated medium. The dilute solution of the first absorber flows through the first solution heat exchanger and then flows back to generator in which it releases refrigerant vapor. Then we gain the recuperative generation-absorption system of solution tandem cycle.
When the first absorber haven't the pipe of heated medium connected external, the heat which is released by absorbing the refrigerant vapor in the first absorber is used to heat the solution which flows through the first absorber.
2. One or two of the recuperative generation-absorption systems in this invention is solution independent loop recuperative generation-absorption system which can be mainly formed by generator, the first absorber, the second absorber, the first solution heat exchanger, the second solution heat exchanger, the steam bleeding chamber, the first solution pump, the second solution pump.
The concentrated solution pipe of generator passes through the first solution pump, the first solution heat exchanger and then connects the first absorber. The dilute solution pipe of the first absorber passes through the first solution heat exchanger and then connects generator. The dilute solution pipe of the second absorber passes through the second solution heat exchanger, the first absorber and then connects the steam bleeding chamber. The concentrated solution pipe of the steam bleeding chamber passes through the second solution pump, the second solution heat exchanger and then connects the second absorber.
Generator has the pipe of residual heat medium or the pipe of thermal driving medium and the channel of refrigerant vapor which separately connect external. The first absorber has the pipe of heated medium and the channel of refrigerant vapor which separately connect external. The second absorber has the channel of refrigerant vapor and the channel of heated medium which separately connect external. The steam bleeding chamber has the channel of refrigerant vapor which connects external.
The dilute solution of generator is heated by the residual heat medium or the thermal driving medium and releases refrigerant vapor at the same time. The concentrated solution of generator flows through the first solution pump, the first solution heat exchanger and then enters the first absorber in which it absorbs the refrigerant vapor coming from outside the system and heats up the solution which flows through the first absorber and meets the heat demand of heated medium. The dilute solution of the first absorber flows through the first solution heat exchanger and then flows back to generator. The solution which flows through the first absorber absorbs heat and a part of it is vaporization and then enters the steam bleeding chamber which releases refrigerant vapor. The concentrated solution pipe of the steam bleeding chamber flows through the second solution pump, the second solution heat exchanger and then enters the second absorber in which it absorbs the refrigerant vapor coming from outside the system and releases heat to the heated medium at the same time. The dilute solution of the second absorber flows through the second solution heat exchanger, the first absorber and then enters the steam bleeding chamber. Then we gain the recuperative generation-absorption system with solution independent loop.
When the first absorber haven't the pipe of heated medium connected external, the heat which is released by absorbing the refrigerant vapor in the first absorber is used to heat the solution which flows through the first absorber.
In a specific and complete second-type absorption unit, the refrigerant vapor and solution all belong to the working medium of unit. In the above generation-absorption system, the first absorber absorbs the refrigerant vapor of outside the system and releases heat to the solution which flows through the first absorber. Then the solution which enters the first absorber absorbs refrigerant vapor and releases heat. The heat is released by working medium. That the solution which flows through the first absorber absorbs heat can be regarded as absorption heat by working medium. This process is called recuperative heat in terms. In the cycle, working medium releases heat in a process which can be used to meet the absorption of heat by working medium in another process. The generation-absorption systems in this invention are recuperative generation-absorption systems.
According to the needed terminal temperature of heated medium, we need to adjust the amount of vapor released by the solution in the steam bleeding chamber. It depends on the quantity of heating load absorbed by the solution which flows through the first absorber. The less the heating load is, the less the amount of refrigerant vapor which separated from the solution in the steam bleeding chamber is. At the same time, the concentration of solution which enters the second absorber increases less and the terminal temperature of heated medium is promoted much less too. What's more, the corresponding performance index of the second absorber is more close to the first absorber's on the condition that the quantity of refrigerant vapor absorbed by the first absorber and the second absorber is consistent. In a certain range, the second-type absorption heat pump which is combined with this invention can achieve high-temperature heating with a higher performance index.

What we need to clarify is as follows:
Firstly, in theory, the steam pressure in the second absorber 3 and the first absorber 2 is consistent. Meanwhile, the third solution pump 9 is used to overcome the resistance when the solution flows through the heat exchanger and the pipeline. But the solution pump will save when the altitude (gravity) difference exists and can be used. The third solution pump 9 can save too when the pressure of the second absorber 3 is higher than the pressure of the first absorber 2.
Secondly, the solution heat exchanger can act as the throttle which is used for throttling step-down.
Thirdly, the solution independent cycle in the solution independent cycle generation-absorption system refers to that the solution is divided into two ways with independent cycle in the process of generation-absorption system.
Fourthly, the solution tandem cycle in the solution tandem cycle generation-absorption system refers to that the solution flows orderly through all components of generation-absorption system in the process of generation-absorption system. And the parallel double-effect in the single stage parallel double-effect absorption heat pump refer to that the solution cycle is parallel when the absorption heat pump realize double-effect process. So do single stage parallel triple effect.
Fifthly, the tandem cycle double-effect in the single stage tandem cycle double-effect absorption heat pump refers to that the solution cycle is tandem when the absorption heat pump realizes the double-effect process. So do single stage tandem triple effect.
Sixthly, in the recuperative single stage double-effect absorption heat pump, the first generator 1 and the second generator A2 all can be used as the high-pressure generator or low-pressure generator. They can be called as the high-pressure generator or low-pressure generator when it is necessary. Similarly, in the recuperative single stage triple effect absorption heat pump, the first generator 1, the second generator A3 and the third generator B3 all can be used as the low-pressure generator, medium voltage generator or low-pressure generator. They can be called as the high-pressure generator, medium voltage generator or low-pressure generator when it is necessary too.
Now combining the appended drawings and examples, we described the present invention in detail.
The solution tandem cycle recuperative generation-absorption system shown in
Firstly, structurally, it is mainly formed by the generator, the first absorber, the second absorber, the first solution heat exchanger, the second solution heat pump, the steam bleeding chamber, the first solution pump, the second solution pump and the third solution pump.
The generator 1 has the concentrated solution pipe which passes through the first solution pump 7, the first solution heat exchanger 4, the first absorber 2, and then connects the steam bleeding chamber 6. The steam bleeding chamber 6 has the concentrated solution pipe that passes through the second solution pump 8, the second solution heat exchanger 5 and then connects the second absorber 3.

The first absorber 2 has the heated medium pipe and the refrigerant vapor pipe which separately connects external. The second absorber 3 has the refrigerant vapor channel and the heated medium pipe which separately connects external. The steam bleeding chamber has the refrigerant vapor pipe connected external.
Secondly, on the process, the residual heat medium or thermal driving medium heats up the dilute solution of the generator 1 and releases the refrigerant vapor. After that the concentrated solution of the generator 1 flows through the first solution pump 7, the first solution heat exchanger 4, the first absorber 2 and absorbs heat making parts of it vaporization, the concentrated solution enters the steam bleeding chamber and releases the refrigerant vapor. The concentrated solution of the steam bleeding chamber 6 flows through the second solution pump 8, the second solution heat exchanger 5 and then enters the second absorber 3 where it absorbs the refrigerant vapor coming from outside the system and releases heat to heated medium. The dilute solution of the second absorber 3 flows through the second solution heat exchanger 5, the third solution pump 9 and then enters the first absorber 2 where it absorbs the refrigerant vapor coming from outside the system and heats up the solution which flows through the first absorber 2 for meeting the heat demand of heated medium. The dilute solution pipe of the first absorber 2 flows through the first solution heat exchanger 4 and then reflows to generator 1 in which it is heated to release refrigerant vapor. Then we gain the solution tandem cycle recuperative generation-absorption system.
