การถ่ายเทความร้อนและการควบแน่นของสารทำความเย็นในท่อที่มีครีบตามแนวนอน

Abstract

The engineering project was educated about heat transfer and condensation of Refrigerant in pipe with horizontal fins. Heat exchanger is concentric type by refrigerant R-12 andR-22 working fluid in the system. The heat transter coefficient of refrigerant And pressure drop in pipe. The result show many factors effected to the heat transfer coefficient and Condensation in pipe. For power compressor in stantly, the condensation and heat transfer increases with cooling water flow rate. As the Water flow rate constantly, power Compressor increased, the heat transfer coeffcient increased too.
