<p>PROBLEM TO BE SOLVED: To permit the improvement of an energy efficiency by providing a pressure reducing device or an opening degree adjusting means to control the flow rate of refrigerant, which flows into respective coolers, in a refrigerator controlling a freezing chamber and a refrigerating chamber independently. SOLUTION: A closed circuit is constituted by connecting a compressor 31, a condenser 32, an opening degree adjusting means 40, a first cooler 27 and a second cooler 29 sequentially through a refrigerant pipe 34 while a refrigerating chamber fan 28 and a freezing chamber fan 30 are provided near the first cooler 27 and the second cooler 29. Cold air, produced by the first cooler 27 and the second cooler 29, is supplied to a freezing chamber and a refrigerating chamber by the operation of the refrigerating chamber fan 28 and the freezing chamber fan 30. Then, the pressure of refrigerant of high pressure side is reduced by the opening degree adjusting means 40 to discharge the same into low pressure side. In this case, when the cooling operation of the refrigerating chamber 23 is started by driving the refrigerating chamber fan 28, the opening degree of the opening degree adjusting means 40 is increased to increase the flow rate of refrigerant and reduce a pressure difference between the high pressure side and the low pressure side.</p> |
