    摘 要：提出了一種全新的利用廢熱來(lái)動(dòng)態(tài)制取流態(tài)冰的系統(tǒng)的構(gòu)想：系統(tǒng)由三個(gè)部分復(fù)合而成.其中工質(zhì)冷卻部分一方面產(chǎn)生一定的冷量用于對(duì)制冰的水進(jìn)行預(yù)冷，而另一方面其排出的熱量并未被浪費(fèi)而是被重新利用于驅(qū)動(dòng)復(fù)合系統(tǒng)其他部分的運(yùn)行，并完成整個(gè)系統(tǒng)的循環(huán)，從而使系統(tǒng)整體的運(yùn)行效率得到了提高。詳細(xì)介紹了系統(tǒng)的構(gòu)造原­理和工作流程并深入探討了其可行性，在此基礎(chǔ)上設(shè)定工況的條件下對(duì)系統(tǒng)運(yùn)行的性能系數(shù)進(jìn)行了分析計(jì)算并將該系統(tǒng)與目前常用的幾種制冰方法進(jìn)行了比較。結(jié)果表明該系統(tǒng)設(shè)計(jì)可以克服目前使用較廣的三種動(dòng)態(tài)制冰的系統(tǒng)的缺陷，而在與過(guò)冷水動(dòng)態(tài)制流態(tài)冰系統(tǒng)的比較中發(fā)現(xiàn)該新系統(tǒng)的性能系數(shù)在一定的工況下可以提高30%以上。

Abstract In our study, a novel method to dynamically make binary ice by using waster heat was proposed. A system based on this method consists of three parts, in which the heat rejected from the pre-cooling part is applied to drive the other parts so that the performance of the system can be improved. The working principle and feasibility of the present ice making system were analyzed. The simulation results indicate that the system performance with the novel method could increase by more than 30% under considered conditions. 8Refs. In Chinese.
