Flow patterns during condensation of three refrigerants: microfin vs. smooth tube.
Author(s) : DORETTI L., FANTINI F., ZILIO C.
Summary
The performance of microfin tubes during condensation of refrigerants was studied experimentally and theoretically. In previous papers the present authors reported their own data when condensing R134a inside two different tubes: a 9.5 mm outer diameter microfin tube (7.69 mm inside diameter at the fin tip and 60 fins with 0.23 mm fin height and 13° helix angle) and a plain 8 mm inner diameter tube.
