Abstract: A multi-chamber refrigeration system is described. The refrigeration system comprises a first refrigeration compartment within a housing, and a second refrigeration compartment within the housing and mechanically coupled to the first refrigeration compartment. A control unit is electrically coupled to the first refrigeration unit and the second refrigeration compartment. A compressor is coupled to the control unit through a first solenoid valve and through a second solenoid valve. The first solenoid valve is operable to alter an operating temperature of the first refrigeration compartment, and the second solenoid valve operable to alter an operating temperature of the second refrigeration compartment.
