Patent number: 11287172Abstract: An augmented heat transfer system can be used to control the humidity of adjacent conditioned spaces by selectively absorbing latent heat energy from a relatively warm space, such as a loading dock, and discharging this energy in the form of sensible heat to an adjacent relatively cold space, such as a freezer served by the loading dock. This transfer of sensible heat energy into the cold space induces a vapor compression system to remove sufficient moisture from the cold space to avoid uncontrolled precipitation. At the same time, the process of removing moisture/latent heat from the warm space can also be used to reduce humidity in the warm space via condensation on a cold evaporator. Therefore, in operations where the warm space and the cold space are both nominally sealed from ambient air, such as an indoor loading dock serving a freezer, the augmented heat transfer system can eliminate uncontrolled precipitation in the freezer while also mitigating moisture ingress to the freezer from the dock space.Type: GrantFiled: January 29, 2019Date of Patent: March 29, 2022Assignee: Tippmann Companies LLCInventor: Daniel J.

Publication number: 20190274336Abstract: 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.Type: ApplicationFiled: December 21, 2018Publication date: September 12, 2019Applicant: Tippmann Companies LLCInventor: Daniel J.

Publication number: 20190241311Abstract: 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.Type: ApplicationFiled: April 15, 2019Publication date: August 8, 2019Applicant: Tippmann Companies LLCInventor: Daniel J.

Patent number: 9915463Abstract: 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.Type: GrantFiled: February 27, 2017Date of Patent: March 13, 2018Assignee: Tippmann Companies LLCInventor: Daniel J.

Patent number: 9784490Abstract: 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.Type: GrantFiled: March 14, 2013Date of Patent: October 10, 2017Assignee: Tippmann Companies LLCInventor: Daniel J.

Patent number: 9297570Abstract: 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.Type: GrantFiled: June 11, 2014Date of Patent: March 29, 2016Assignee: Tippmann Companies LLCInventor: Daniel J.
