    摘 要：設(shè)計了平行流冷凝器，對12m客車空調(diào)的管片式冷凝器實現(xiàn)整體替代.在標準空調(diào)工況進行的焓差法對比性能實驗表明：制冷量Q和能效比EER都略有提高，技術(shù)指標滿足設(shè)計要求.替代后，冷凝器的質(zhì)量減輕30 kg、尺寸減少40%，制冷劑R134a的充灌量減少16%，推進了客車空調(diào)系統(tǒng)的輕量小型化，成本效益顯著.同時，發(fā)現(xiàn)平行流式冷凝器制冷劑側(cè)流動阻力相對于管片式明顯增大。

Abstract A parallel flow condenser has been designed to replace the conventional finned-tube condenser for the bus air conditioning. The experiment was conducted using the enthalpy difference method under the standard conditions. The results show that the refrigerating capacity and the energy efficiency ratio of the system improved slightly. Compared with the finned-tube condenser, the weight, the size, and the refrigerant charge of the condenser assembly decreased by 30 kilogram, 40%, and 16%, respectively. However, the flow resistance of the refrigerant side increased obviously. 7Refs. In Chinese.
