A method of cooling air includes a liquid coolant subsystem including a cool water source configured to hold water, an air cooling subsystem including an air chamber that contains air therein, an air conditioning apparatus including a heat exchanger of a liquid-to-air type having a heat sink in thermal communication, a fan assembly configured to move air along the heat sink of the heat exchanger, a thermostat, a temperature sensor, and a control circuit in electronic communication with the temperature sensor and the thermostat, a plumbing subsystem including an inlet piping component in fluid communication with heat exchanger, an outlet piping component in fluid communication with the exchanger, and a solenoid valve. The control circuit may be configured to activate the fan assembly and to open the solenoid valve, allowing for the transfer heat to water from the air moved by the fan assembly.

A container refrigeration device includes: a fan controller which reduces a rotation speed of an inside fan when a temperature inside a container is stabilized; and a rotation speed controller which reduces an operational rotation speed N of a compressor such that the temperature inside the container becomes equal to a target temperature as the fan controller reduces the rotation speed of the inside fan.

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.

Integrated air conditioning and water-harvesting systems are disclosed. In these systems, one subsystem (air conditioning or water-harvesting) may be a primary subsystem and the other subsystem may be a secondary subsystem. As load on the overall system increases to the point the cooling demands for both subsystems cannot be met simultaneously, the system automatically reduces output of the secondary subsystem. In certain embodiments, an atmospheric water-harvester may be connected into the (potentially pre-existing) chilled-water system that provides cooling throughout a building, either via distributed fan-coil units or a centralized air-handling unit. Additionally, providing cooled-air exhaust from an atmospheric water-harvester to a building's cooling system allows substantial quantities of water to be produced at nominal incremental operating cost over a simple, straightforward air conditioning system.

A method of manufacturing a refrigerator comprises preparing an inner case including an ice making chamber and an opening; preparing an outer case to be coupled to an outside of the inner case; preparing a refrigerant pipe assembly including a refrigerant pipe having at least a portion to be disposed in the ice making chamber to supply cooling energy, and a refrigerant pipe insulator to insulate the refrigerant pipe; inserting the refrigerant pipe assembly into the opening of the inner case in an inward direction from the outside of the inner case such that a portion of the refrigerant pipe insulator is disposed in the ice making chamber, and a remaining portion of the refrigerant pipe insulator is disposed between the inner case and the outer case; and foaming a body insulator between the inner case and the outer case, thereby supporting the refrigerant pipe insulator by the body insulator.
