Benefits of technology

The patent describes a refrigerator with two sides and an opening for accessing the storage compartment. The refrigerator has two cooling circuits, one for the storage compartment and one for the outgoing air. The refrigerator also has a door that can be opened and closed to access the storage compartment. The refrigerator can operate in a single mode or a dual mode depending on the needs. The technical effects of this patent include improved cooling efficiency and flexibility in accessing the storage compartment.

Problems solved by technology

In addition, these refrigerators are often frequently opened and closed.
Unfortunately, opening a door on a refrigerator permits air at ambient temperature to enter a storage compartment of the refrigerator.
Frequently opening the door increases the amount of ambient air that enters the refrigerator.
Older refrigerators that relied upon simply running cooling systems longer, more frequently, or using larger cooling systems typically do not meet the new goals and regulations.

Abstract

A refrigerator operates in a single mode and a dual mode. A plurality of sides defines a storage compartment. At least one door provides access to the storage compartment via an opening in at least one of the sides. At least one outlet vent expels air across the at least one opening towards at least one inlet vent configured to receive at least a portion of the expelled air. A first cooling circuit is fluidly coupled to at least the storage compartment. A second cooling circuit is fluidly coupled to at least one of the outlet vent, the inlet vent, and at least one air screen inlet vent. The refrigerator operates in the single mode when the door is closed during which the first cooling circuit operates. The refrigerator operates in the dual mode when the door is open during which the first cooling circuit and the second cooling circuit operate.

Description

BACKGROUND[0001]The present application relates to refrigerators and freezers, typically of the commercial variety although the disclosed embodiments may be used for private / personal refrigerators.[0002]The hospitality, catering, and institutional markets use and require refrigerators and freezers adapted to their unique operating environments. For example, these markets require a refrigerator with a large capacity and the ability to store not just fresh foods, but also prepared foods, including entire prepared meals. In addition, these refrigerators are often frequently opened and closed.[0003]Unfortunately, opening a door on a refrigerator permits air at ambient temperature to enter a storage compartment of the refrigerator. This warmer air must then be cooled by the cooling system of the refrigerator to ensure that the interior temperature of the storage compartment remains sufficiently cool. Frequently opening the door increases the amount of ambient air that enters the refriger...
