In order to clarify the frost adhesion area on the inner wall of freezer compartment, defrost simulation technique for prediction the vapor change from the frost of the heat exchanger was developed. As a frost melting modeling, physical properties were only considered, and the volume and shape change of frost layer were ignored. This simulation technique was verified by the experiment under the defrost of heat exchanger by forced convection and the defrost condition of refrigerator. Calculated time variation of heat exchanger pipe surface temperature is agreed with experimental one. In addition, calculated time variation of air temperature and absolute humidity at the outlet of the heat exchanger are generally agreed with those for experiment with the progress of melting of frost. However, at the beginning of frost melting, increasing of the above mentioned calculated values is a little bit faster than those for experiment. It is considered that the difference between them is caused by not considering of changing of sectional air duct area between fins.
