A defrost system for a vapor-compression based refrigerator/freezer combines increased operational efficiency with a high likelihood of robust adoption by technical and business personnel. The system includes a controller programmed to monitors and reports several key performance indicators on each evaporator of the system, and to provide reliable, repeatable “initiate defrost” and “terminate defrost” signals which may prompt actions by an operator or automatically control system components. The controller is designed to provide accurate and efficient defrosting signals regardless of the style of evaporator used, the location of the evaporator and other conditions including pull-down, high traffic locations and operations, and low use periods such as weekends.

A sheet-based cover assembly can be used to create an air seal around a palletized product assembly. The assembly includes a plurality of flexible poles which support a covering. In an at-rest state unaffected by external forces, the flexible poles hold the covering open and allow the palletized product assembly to be installed in position, ready to be acted on by a vacuum-creating fan or air handler. When the fan is activated, the vacuum draws the covering tight around the palletized product assembly, deflecting the poles under the force of the vacuum pressure created by the fan. The sheet covering is flexible but relatively air-impermeable, such that the vacuum created behind the palletized product assembly flows primarily through, rather than around, the product.

Systems and methods for measuring a temperature of a product are provided. An example method includes providing a temperature probe assembly. The temperature probe assembly includes a temperature probe configured to sense a temperature, a body in electrical communication with the temperature probe, and a scanner fixed to the body. The method further includes scanning a code, via the scanner, and receiving a temperature reading, via the temperature probe. The temperature reading corresponds to a temperature of a product in which the temperature probe is inserted. The method further includes outputting an indication of the temperature reading, based on the code.

A high efficiency airflow management system can be used to reliably and consistently draw air through palletized product stacks with a minimum of energy expenditure. A racking system is provided with a grid of pallet bays separated from an air plenum/chamber by a wall having an airflow opening for each pallet bays. An air seal is formed at the periphery of each opening by resiliently flexible side seals and a top seal to form a highly airtight interface between the pallet assembly and the adjacent airflow opening. When a pressure differential is developed between the chamber and the pallet bay, air is efficiently drawn substantially exclusively through the pallet assemblies with minimal leakage. The flexible sealing arrangement accommodates pallet assemblies with unevenly stacked rows of cases without significant loss of system efficiency.

Systems and methods for airflow management around palletized cases of goods in a warehouse storage facility are provided, in which airflow around each individual layer of cases is facilitated while airflow “spillage” around the sides, top or bottom of pallet assemblies is minimized or eliminated. One exemplary device for such airflow management includes palletized product spacers disposed between respective layers of vertically stacked cases, in which the product spacers facilitate a substantially unidirectional longitudinal airflow. Another exemplary airflow management device is a series of automatically adjustable air dams disposed at the tops of respective pallet assemblies which prevent air spillage and establish intermediate air manifold spaces. Yet another device is a lateral pallet spacer prevents direct abutment of the side surfaces of neighboring pallet assemblies and thereby ensures that the air manifold spaces are in fluid communication with the spacers of multiple pallet assemblies.

A modular air handler is adapted for installation in a racking assembly behind palletized product. The air handler operates to move air through the adjacent layers of palletized product upon placement of the palletized product in the adjacent space.

An automatically adjustable swing seal for a rack-aisle freezing and chilling system extends, for example, from the top horizontal frame member of a racking structure and defines an intake opening along with side seals and a bottom seal. The swing seal is positioned at a height such that a product stack having a top edge positioned at any point along the face of the swing seal creates a seal between the intake opening and the stack via the swing seal, the side seals, and the bottom seal. Thus, stacks of varying heights may automatically be accommodated. Further, the bottom edge of the swing seal may be beveled, such that if a product stack is not evenly stacked a portion of the uneven stacking will not catch against the swing seal when the stack is pulled away from the opening.

An installation and method for freezing and cold storage of palletized product. A chiller is provided in the interior of a cold storage warehouse space that maintains the temperature of ambient air within the space below freezing. A plurality of racking structures each define an air flow chamber having air intake openings on opposite sides thereof and an air outlet to enable freezing air to be drawn into the chamber through the intake openings and exhausting into the warehouse space. Pallets on pallet guides are pressed against the intake openings such that freezing air is drawn through the palletized product to thereby quickly freeze the product. The pallet structure and air flow chambers are arranged in spaced-apart rows to enable a forklift to pass down the aisles so as to place and remove the palletized product.

A refrigeration system includes a supplemental heat exchanger operably disposed between a condenser and an evaporator. This supplemental heat exchanger is located in selective fluid communication with the air in the conditioned space, and can be toggled between an “invisible” mode in which the heat exchanger acts as a simple fluid conduit between the condenser and evaporator, and a “humidity reduction” mode in which the heat exchanger operates to transfer heat from hot refrigerant to the colder conditioned space. This addition of heat into the conditioned space decreases the relative humidity of the conditioned space and subcools the refrigerant leading to the expansion valve and evaporator. This subcooling of the liquid enables the evaporator to operate at a lower temperature which enhances the moisture removal from the air moving through the evaporator. The supplemental heat exchanger may be located in a physically elevated position relative to the remainder of the conditioned space to utilize stratification of hot air to create a default “invisible mode” without inducing airflow.
