Abstract
A variable refrigeration system including a cooling system having a compressor, a condenser, and a refrigerant. An active insulation system includes an insulation portion disposed therein that holds a gas. The insulation portion is operably connected to the compressor and includes an insulation panel adjacent a refrigerated compartment. A controller is operably connected to the cooling system and to the active insulation system. The controller operates between a first stage, wherein the controller sends a signal to the compressor to compress the refrigerant in the cooling system, and a second stage, wherein the controller sends a signal to the compressor to alter the gas content in the insulation portion of the active insulation system.
