Abstract

A refrigerator incorporates a variable speed refrigeration system including a variable speed compressor, an evaporator fan, a fresh food compartment stirring fan and a multi-position damper. Various temperature sensors are provided to sense system parameters which are used by a controller to regulate each of the variable components in order to compensate for temperature changes within a refrigerator compartment and, maintain the compartment within a confined temperature band, in a highly effective, energy efficient and synergistic manner.
