摘要

在有机朗肯循环（ORC）系统其他部件的效率均相同的条件下，蒸发器的换热量越大，不可逆损失越小，系统的做功潜力就越大。由于混合工质的相变温度滑移与热源的温度变化具有较好的“匹配性”，采用混合工质为循环工质，并使用

Abstract

Under the condition of the same efficiency of other parts of organic Rankine cycle (ORC) system

the greater the heat exchange capacity of the evaporator

the smaller the irreversible loss

and the greater the potential of the system. Because of the phase transition temperature glide of mixture has good “matching” with the temperature change of heat source

this paper uses mixture as working fluid

and uses entransy flow dissipation rate to represent the irreversible loss of heat transfer process between mixture and heat source fluid. Combining

T-Q

diagram

the heat transfer process of mixture and heat source fluid in evaporator is analyzed. It is found that the area enclosed by the heat transfer curves of mixture and heat source fluid is the entransy flow dissipation rate

and the conditions of maximum heat transfer quantity and minimum irreversible loss of evaporator are obtained respectively

to guide the selecting of the optimal mixture and operation condition. According to the determined heat source

under the condition of max

imum heat transfer quantity

a method for selecting the optimal mixture and optimal operating condition of the system based on the performance of evaporator is established. Adopting the heat source listed in reference paper

the optimum mixture and optimum outlet temperature are R600a/R134a(0.2/0.8) and 365.75 K

respectively. The heat transfer quantity of the evaporator is 3.3 times

under the condition that the parameters of other parts of the system are the same

the net output power of the system is 2.4 times than the optimum mixture in the literature.
