Description

Multi-effect first type absorption heat pump

Technical field:

The invention belongs to the field of low temperature waste heat utilization and heat pump/refrigeration technology.

Background technique:

The first type of absorption heat pump uses the temperature difference between the heat medium and the heated medium as the driving force. When the driving temperature difference is large, the double-effect or multi-effect process should be used to provide the high-temperature driving heat utilization rate; in any heat transfer process In the case of any heat transfer, the temperature difference waste will bring about a reduction in the utilization rate of heat energy. That is to say, whether it is the transfer of heat of condensation or the transfer of heat, the heat transfer of any heat load should be in one step. Only a reasonable degree of thermodynamic perfection can be guaranteed.

In conventional multi-effect cycles utilizing heat of condensation and heat absorption, the transfer of heat of absorption for the heated solution is achieved by means of an intermediate circulating medium, which results in three heat differences in the transfer of absorbed heat - absorption heat transfer to the intermediate circulating medium The temperature difference, the temperature change of the intermediate circulating medium and the intermediate circulating medium will transfer the heat to the temperature difference in the heated solution, and also need to consume the cycle work; in the equipment and working medium, two sets of heat exchange tubes, one circulation pump and Intermediate circulation medium. If the heat of absorption is transferred to the heated solution through a heat transfer step, only one set of heat exchange tubes is needed, which not only greatly simplifies the structure of the device, but also saves two heat transfer temperature differences and one cycle work; the saved temperature difference is used for Acting on the heat pump cycle process, the temperature difference between the double effect and the third effect can be realized to realize the three-effect process, which is beneficial to increase the utilization value of the driving heat load and improve the heat energy utilization rate.

In addition to eliminating unreasonable heat transfer temperature differences, the first type of absorption heat pump cycle process needs to achieve more requirements, including: smooth changes in thermodynamic parameters, adjustable heating parameters, can better adapt to working conditions Change, have the best performance index; can realize the deep utilization of high temperature heat resources, or use different grades of driving heat resources to achieve the comprehensive utilization of high temperature driving heat; can use different working solutions, which is beneficial to drive the working parameters of heat medium The matching of the cycle process improves the level of temperature difference utilization.
