Description

The multiple-effect first-class absorption type heat pump

Technical field:

The invention belongs to low temperature heat and absorption type heat pump.

Background technology:

First-class absorption type heat pump as driving force, should adopt economic benefits and social benefits or multiple-effect flow process that the utilization rate of high temperature driven heat is provided with the temperature difference between driving thermal medium and the heated medium when the driving temperature difference is larger; In any heat transfer process, the reduction that the temperature difference waste of any heat transfer link all will bring heat utilization rate, that is to say, no matter be the transmission of condensation heat, or absorb the transmission of heat, the heat transfer link of any thermic load all should settle at one go, so just can guarantee to obtain rational thermodynamics sophistication.

In traditional multiple-effect circulation that utilizes the heat of condensation and absorption heat, the transmission that is used for the absorption heat of heated solution relies on intermediate cycle medium to realize, this causes absorbing three temperature difference of transmission needs of heat---and absorption heat is delivered to the temperature difference of intermediate cycle medium, variations in temperature and the intermediate cycle medium of intermediate cycle medium will absorb the hot temperature difference that is heated in the solution that is delivered to, but also need to consume the circulation merit; Then needing two groups of heat-exchanging tube bundles, circulating pump and intermediate cycle medium aspect equipment and the working medium.Be heated in the solution if will absorb hot being delivered to by a heat transfer link, then only need one group of heat-exchanging tube bundle, not only device structure is greatly simplified, and has also saved two heat transfer temperature differences and a circulation merit; The temperature difference of saving is used for acting on the heat pump cycle flow process, can make the temperature difference of script between economic benefits and social benefits and triple effect realize the triple effect flow process, and this is conducive to improve the value that drives thermic load, improves heat utilization rate.

Except eliminating irrational heat transfer temperature difference, the circulation process of first-class absorption type heat pump also will be realized more requirement, and these requirements comprise: the thermodynamic parameter smooth change, and heating parameter can be regulated, adaptation condition changes preferably, has best performance index; Can realize the deep exploitation to the high temperature thermal resource, or utilize the driving thermal resource of different grades with the comprehensive utilization of realization high temperature driven heat; Can adopt different operating solution, be conducive to drive the coupling of thermal medium running parameter and circulation process, improve the temperature difference and utilize level.
