【摘要】：基于低溫工況下的純電動汽車熱泵空調(diào)系統(tǒng),為降低排氣溫度、提高換熱性能,分別設(shè)計了中壓、低壓混氣熱泵空調(diào)系統(tǒng),并建立相應(yīng)系統(tǒng)數(shù)學(xué)模型,模擬計算系統(tǒng)的排氣溫度、換熱量等主要性能參數(shù),并與實驗數(shù)據(jù)進行對比。研究表明:相對于中壓混氣熱泵空調(diào)系統(tǒng),低壓混氣熱泵空調(diào)系統(tǒng)較穩(wěn)定高效,更能滿足電動汽車在低溫環(huán)境下的需求。
[Abstract]:In order to reduce exhaust temperature and improve heat transfer performance of pure electric vehicle heat pump air conditioning system at low temperature, the air conditioning system of medium pressure and low pressure air mixture heat pump is designed, and the corresponding mathematical model is established. The exhaust temperature, heat transfer and other main performance parameters of the system are simulated and compared with the experimental data. The results show that the low pressure air mixture heat pump air conditioning system is more stable and efficient than the medium pressure air mixture heat pump system, and it can meet the demand of electric vehicle in low temperature environment.
