  • Patent number: 6679065
    Abstract: A temperature controlled apparatus comprises a reversible solid state device having a first section and a second section; portions of the first and the second sections are disposed in intimate contact. The first section is disposed adjacent to a portion of an external wall surface of a compartment and the second section is disposed adjacent to a portion of an internal wall surface of the compartment. A compartment fan is disposed within the compartment. The reversible solid state device and the compartment fan are coupled to a controller. The controller is configured to modify a compartment air temperature inside the compartment by controlling the reversible solid state device and the compartment fan to flow a compartment air across the second section. The controller is configured to control the reversible solid state device and the compartment fan in at least one temperature operational mode.
