Abstract: The present application provides a refrigerated merchandising case. The refrigerated merchandising case may include a refrigerated product area, a rear panel with a roller channel and a number of support apertures, and a number of shelves with a roller and a number of attachment prongs. The shelves may maneuver along the rear panel via the roller within roller channel and attach via the attachment prongs and the support apertures.

Abstract: A refrigeration display case for refrigerating and displaying perishable goods includes a plurality of evaporator coils for cooling air, a display case frame forming a display area, and a coil cover for at least substantially covering a portion of the plurality of evaporator coils and coupled to the display case frame. The coil cover includes a planar member having a living hinge formed in the planar member extending from a first side end to a second end and defining a first portion of the planar member and a second portion of the planar. The living hinge is configured to allow movement between the first portion of the planar member and the second portion of the planar member. Other embodiments and designs are included.

Abstract: A refrigeration system includes a first circulation fan electrically coupled to a power source via a first load wire. A relay is electrically coupled to the first circulation fan via a second load wire and to the power source. In an open position, the relay interrupts electrical voltage from the relay to the first circulation fan via the second load wire causing the first circulation fan to operate in a low-speed mode. In a closed position, the relay supplies electrical voltage to the first circulation fan via the second load wire causing the first circulation fan to operate in a high-speed mode. Operation of the first circulation fan in the high-speed mode reduces a defrost cycle time associated with the refrigeration system relative to operation of the first circulation fan in low-speed mode.

Abstract: Display cases may include deflectors and fans. The deflectors may alter air currents generated by fans to provide an air current to display portions of the display case. In some implementations, the altered air current may have a first portion with a velocity that is greater than a velocity of a second portion, where the first portion is closer to a display portion of the display case.

Abstract: A refrigeration control apparatus comprises a master unit with a mother board. The mother board comprises a bus configured to carry signals between boards coupled to the mother board. A processor board interfaced to the mother board is provided. The processor board comprises a processor, and a program memory where instructions for the processor are stored on the program memory. An interface circuit coupled to the mother board is provided. A load control module interfaced to the mother board is provided, wherein the load control module comprises an interface circuit coupled to the mother board, and a circuit breaker coupled to a power input. A load relay comprising a first interlocked relay and a second interlocked relay coupled to the circuit breaker is provided. The load relay is configured to switch power. An override switch and the processor coupled to the load relay to control the load relay is provided.
