This study aims to make and analysis a tube group type evaporator design alternately with crossing flow as a result of modification of split PK 1 evaporator AC and to evaporate the working fluid, namely R-22, to environmental so that it also simultaneously cools the room. The evaporator designed has a length of 26 cm, a width of 16 cm and a height of 84.2 cm, with a tube diameter of 6.35 mm, a tube length of 58 cm and as many as 25 passes, consisting of 5 rows and 5 columns with alternating positions, distance between tubes 15 mm vertically and horizontally. With this design, the evaporator reduce the temperature air inlet of 0.08.
