Abstract: An example control system for a temperature controlled environment operates by alternatively executing on-cycles during which the controller controls the compressor to operate in an on-state and off-cycles during which the controller controls the compressor to operate in an off-state. During the off-cycle the control system executes a defrost cycle. To reduce power consumption of the temperature controlled environment, the control system executes a particular defrost cycle during the off-cycle based upon a stored indication of defrost cycle type.

Abstract: An example control system for a temperature controlled environment operates by monitoring sensor data indicating a temperature associated with a temperature controlled environment, starting a compressor cycle, and ending the compressor cycle based on: the time since the start of the compressor cycle exceeding a maximum compressor runtime; the temperature being at or below a first set point temperature and the time since the start of the compressor cycle reaching a first minimum compressor runtime; the time since the start of the compressor cycle reaching a threshold duration of time without the temperature associated with the return airstream reaching the first set point temperature, and the temperature being at or below a second, higher, set point temperature; and/or the temperature being at or below a minimum temperature and the time since the start of the compressor cycle exceeding a second, shorter, minimum compressor runtime.

Abstract: An accessible cooling environment includes a back wall, an opening opposite the back wall, a roof panel, first and second side walls at least partially defining the opening, and an interior space at least partially defined by the back wall, roof panel, and first and second side wall. A fan configured to circulate air through the interior space, an evaporator disposed inside the interior space, and an air curtain assembly configured to form an air barrier adjacent to the opening. The air curtain assembly includes one or more deflectors for separating the air barrier into a first air curtain and a second air curtain. The first air curtain has a first temperature and the second air curtain has a temperature lower than the first temperature.

Abstract: A system for cooling a product includes an enclosed environment having an outlet, an inlet, and a temperature in a first temperature range. An antechamber is at least partially surrounding the inlet of the enclosed environment and has a temperature in a second temperature range. A conveyor system includes a conveyor path extending between the inlet and the outlet of the enclosed environment and provides a spiral travel path. The temperature range of the enclosed environment is configured to cool the product before the product exits through the outlet of the enclosed environment.

Abstract: A method of manufacturing a hybrid insulating panel includes providing a mold of a frame, dispensing a first foam material in a liquid phase in the mold, and placing a beam in the mold. The method includes curing the first foam material to form an integrated frame, in which the integrated frame includes the beam at least partially surrounded by the first foam. Further, the method includes dispensing a second foam material into a panel cavity to form a panel body. The panel cavity is at least partially defined by a side of the integrated frame. The method includes curing the second foam material to form a panel body, wherein the panel body is secured to the integrated frame.

Abstract: An enclosure for use as a walk-in freezer or refrigerator includes a first panel and a second panel connected to the first panel. Each of the first and second panels includes a body having a frame coupled to the body. The frame includes a beam of a first material and a jacket of a second material at least partially enclosing the beam. An interior edge of the frame is adjacent to the body. An exterior edge is defined by the jacket and defines a joint member. The joint member of the first panel defines a groove, and the joint member of the second panel defines a protrusion adapted to engage the groove of the joint member of the first panel. At least one joint member includes a deformable portion that compresses when the joint member of the first panel engages with the joint member of the second panel.

Abstract: An insulated panel system includes a joint disposed between two insulated panels. The joint has a male portion and a female portion. The female portion has a flange, sidewalls, and a base that can be secured to an existing structure. The male portion includes a top plate with sealing sides that rest against the face of the insulated panel when inserted into the female portion. The sealing sides prevent warm air and/or moisture from ingress into a refrigerated space defined by the insulated panels. Also disclosed is a sealing joint for insulated structural panels.

Abstract: A hybrid structural member for an insulated structural panel includes a core member surrounded on at least two sides by a high-density structural foam. The hybrid structural member may be manufactured by placing a core member in a cavity of an injection mold and surrounding the core member by insulating foam on at least two sides. The core member may be held in place by screws, posts, pins, a vacuum, or other suitable means.

Abstract: An insulated panel system includes a joint disposed between two insulated panels. The joint includes a gasket for increasing the efficiency of walk-in refrigerator and freezer spaces. A butyl-free gasket having a plurality of protrusions may be disposed between a first insulated panel, having a male portion, and a second insulated panel, having a female portion. A latch mechanism, disposed in part in the two insulated panels, operably engages to bring the male portion of the first insulated panel into a sealing engagement with the female portion of the second insulated panel, with the gasket disposed therebetween. The plurality of protrusions of the gasket are compressed between the male and female portions of the first and second panels, such that a plurality of sealing junctions are formed between the first and second panels.
