An ultra low temperature refrigeration system and technique, includes a cabinet with a storage chamber maintained at a certain temperature range, a door providing a seal with the cabinet when engaged with the cabinet, and a dehumidifying unit connected to the cabinet for dehumidifying the storage chamber within the cabinet.

Frost reduction by active circulation

A storage cabinet () is provided for an ultra-low temperature freezer (). The cabinet () includes a base platform (), a plurality of side structural insulated panels () each defining a side wall of the storage cabinet (), and a plurality of generally vertically oriented posts () extending from the base platform (). Each of the plurality of vertically oriented posts () has a slot () for receiving an edge portion (,,) of one of the insulated panels () therealong. The slot (a) may have a generally U-shaped profile that surrounds the edge portion (,,) of one of the insulated panels (). At least one of the generally vertically oriented posts () has a channel () that extends along a longitudinal dimension thereof, the channel () being configured to receive one of insulation, tubing, or wiring of the freezer therethrough.

Modular cabinet for ultra-low temperature freezer

A refrigeration system is provided for use with an ultra-low temperature freezer having a deck and a refrigerated cabinet supported above the deck. The system has a first refrigeration stage and a second refrigeration stage. The first stage defines a first fluid circuit for circulating a first refrigerant. The first stage has a first compressor, a condenser and a first expansion device that is in fluid communication with the first fluid circuit. The second stage defines a second fluid circuit for circulating a second refrigerant. The second stage has a second compressor, a second expansion device and an evaporator that is in fluid communication with the second fluid circuit. The system includes an insulated enclosure supported within the deck and a split-flow heat exchanger that is in fluid communication with the first and second fluid circuits and which is located within the insulated enclosure.
