【摘要】：根據(jù)場協(xié)同原理,可通過改變制冷劑循環(huán)倍率,來改變冷風(fēng)機(jī)場協(xié)同數(shù),從而提高換熱效率。通過試驗(yàn)數(shù)據(jù)計(jì)算得出,當(dāng)蒸發(fā)溫度為-30℃,實(shí)驗(yàn)中的制冷劑循環(huán)倍率從2.5增大到5.0時(shí),換熱器的場協(xié)同數(shù)逐漸升高到趨于基本恒定。所測的降溫速度、計(jì)算的COP均在場協(xié)同數(shù)達(dá)到拐點(diǎn)時(shí)最佳。
[Abstract]:According to the principle of field cooperation, the number of the cold air airports can be changed by changing the cycle rate of the refrigerant so as to improve the heat exchange efficiency. From the experimental data, when the evaporation temperature is-30 鈩，
