Abstract: Methods and apparatus for a two chamber freezer whereby both chambers can be maintained at a substantially constant ultra-low temperature, such as within the range of about −40° C. to −80° C. Short term items may be stored in and accessed by the upper door from an upper chamber while long term items may be stored in and accessed by the lower door in the lower chamber. The upper and lower chambers are thermodynamically independent of each other thereby reducing the power usage of the freezer.

Abstract: A method and apparatus which provides a pressure sensor and/or temperature sensor connected to the low pressure side of a refrigeration system, or the discharge line of a scroll compressor. When the scroll compressor rotates backward, the change of pressure or temperature immediately sends a signal to work with a time-delay relay and a normally closed relay to immediately cut off the electrical power supply to the compressor. Thus, causing the scroll compressor to stop rotating in the undesirable direction.
