In this study, the air-side cooling capacity and pressure drop of an evaporator for a refrigerator unit were experimentally investigated. Using the calorimeter, the performance of the evaporator was verified by changing the fin shape, fin pitch, tube row and air flow rate. The experimental apparatus consisted of the calorimeter which functioned as a constant temperature and humidity chamber and the refrigeration cycle. In order to select the heat exchanger suitable for the evaporator, both air-side cooling capacity and pressure drop should be considered at the same time. From the evaporator performance test by pin type, wavy pin was selected. The optimal performance of the evaporator was observed at the fin pitch of 5 mm, the tube row of 6 row, and the air flow rate of 40㎥/min.
