  • Patent number: 10726964
    Abstract: A system usable in a nuclear environment provides a reservoir of liquefied breathable gas in fluid communication with a deployment system. The deployment system uses a stream of the breathable gas from the reservoir to operate a gas turbine which runs an electrical generator that is mechanically connected therewith to generate electrical power that is stored in a battery bank. The stream of breathable gas then flows from the turbine and is split between a heat exchanger that is situated in heat exchange relation with the interior region of the main control room and an outlet that provides breathable gas to the control room. The portion of the stream that flows through the heat exchanger cools the main control room. The other portion of the stream that provides breathable gas to the main control room also recirculates the atmosphere in the control room.

  • Patent number: 10274219
    Abstract: When a controller determines that a leakage of refrigerant occurs, the controller executes a control of rotating an air-sending fan at high rotation speed. After the control, the controller executes a control of stopping rotation of the air-sending fan or reducing a rotation speed of the air-sending fan in accordance with a result of detection by a first refrigerant sensor provided in a lower portion of a heat exchanger chamber. Thus, the air-sending fan is prevented from continuing the rotation at high rotation speed. Therefore, an indoor unit for an air-conditioning apparatus is excellent in safety and is capable of avoiding feeling of discomfort of a user due to the high-speed rotation of the air-sending fan.

  • Patent number: 8919142
    Abstract: 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 seat 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.

    Abstract: 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.
