摘要
对于水冷空调机的冷凝器,采用螺旋槽锯齿管为换热管,壳程采用折流杆支撑结构,可以大大提高冷凝器的换热性能。试验表明,在额定工况下,以R22为制冷剂,与常规低肋管冷凝器相比,在换热面积减少约37.5%的情况下,空调机的制冷量增加3.7%,能效比提高8.5%。
A rod - baffle condenser with spirally corrugated and savvtooth - shaped finned tube was used in a watercooled air conditioner system. The testing result shows that this air conditioner has higher performance. Compared with air conditioners using normal finned tube（ lower fin） condenser, the refrigerating capacity of this air conditioner increases by 3.7% and energy efficiency ratio increases by 8.5% while heat transfer area of the condenser decreases by 37.5% under the rated working conditions and using R22 as refrigerant.
