ABSTRACT:
A refrigerator includes a mode-change chamber, having first and second dampers which may be selectively used as a freezer compartment, refrigeration compartment or chill compartment. When the freezer compartment mode is selected, the first damper permits the flow of cold air into the mode-change chamber to maintain the temperature in the mode-change chamber at a freezing temperature. When the refrigerating compartment mode is selected, the second damper permits the flow of cold air into the mode-change chamber to maintain the temperature in the mode-change chamber at the selected refrigeration temperature. When the chill compartment mode is selected, the control temperature of the second damper is forcibly expanded by a heater to maintain the temperature in the mode-change chamber at a chill temperature between the freezing and refrigeration temperatures.
