PROBLEM TO BE SOLVED: To prevent the occurrence of dew condensation to a wall surface, in a direct cooling type refrigerated chamber to cool the interior of a chamber through radiation cooling from the wall surface of the refrigerated chamber. SOLUTION: This refrigerator comprises a wall surface cooling pipe 16 arranged in the wall of a refrigerated chamber 10 and performing radiation cooling in a refrigerated chamber by cooling its wall surface; and an air cooling part 18 arranged in the refrigerated chamber 10 and performing cooling of air in the refrigerating room and dehumidification thereof. In this case, after opening and closing of a refrigerated-chamber door 14, a door opening closing time is measured by a measuring part 22, and an air temperature in the refrigerated chamber 10 is detected by an air temperature sensor 20 to calculate a temperature fluctuation in the refrigerated chamber due to opening and closing of the door. Based on the door opening closing time and a temperature fluctuation, an air state after opening and closing of the door is predicted. Based on a predicted air state, the outputs of the wall face cooling pipe 16 and the air cooling part 18 are controlled. |
