REFRIGERATION SYSTEM IS DISCLOSED IN WHICH TEMPERATURE REGULATION AND ENERGY EFFICIENCY ARE IMPROVED. EACH COMPARTMENT (7, 8) TO BE COOLED IS PROVIDED WITH A VARIABLE SPEED FAN (10, 11), THE SPEED OF WHICH IS CONTROLLED DEPENDENT ON THAT COMPARTMENT'S TEMPERATURE, THE TEMPERATURE REQUIRED OF THAT COMPARTMENT, AND THE DIFFERENCE BETWEEN REQUIRED AND ACTUAL TEMPERATURES FOR ANY OTHER COMPARTMENTS. THE TEMPERATURES ARE MONITORED CONTINUALLY AND FAN SPEEDS ALTERED SO THAT THE COMPARTMENT FURTHEST FROM ITS REQUIRED TEMPERATURE RECEIVES THE MOST COOLING (HIGHEST FAN SPEED). AN ALTERNATIVE EMBODIMENT IS ALSO DISCLOSED WHEREIN THE SPEED OF ONE COMPARTMENT'S FAN IS FIXED AND THE OTHER VARIED. (FIG. 2)
