Disclosed herein are an apparatus, method and system for storing perishable items that degrade in the presence of oxygen and/or humidity and that are frequently accessed by a consumer. The apparatus comprises an openable insulated vessel with precisely controlled internal temperature and humidity, which becomes airtight when closed, and a corona ozone generator with an oxygen gas feed tank and fan within the insulated airtight enclosure, which converts ambient oxygen trapped within the airtight enclosure into ozone by circulating the enclosed volume of air through the corona ozone generator after the vessel is opened and then closed. Also disclosed is a refrigerated embodiment of the apparatus, which may be self-contained and transportable. The apparatus is network connected to allow for remote control and monitoring and sends alerts to web applications or mobile applications when monitored parameters substantially vary from their settings.

The invention provides an underground thermal energy storage having a shape selected from substantially cylindrical and an n-gonal prism, having an axial direction that in use is vertical, and comprising an inner volume for holding a liquid, said energy storage device comprising a peripheral outer wall, a peripheral inner wall around said inner volume, and a filling layer between said inner wall and said outer wall, said inner wall comprising a series of modular wall parts provided with a heat exchanger for exchanging thermal energy with said liquid, said modular wall parts arranged in rings and said modular wall parts each having opposite radial surfaces that are in use vertical, an inner tangential surface contacting said inner volume, an outer tangential surface directed towards said outer wall, and opposite axial surfaces that are in use horizontal, said modular wall parts comprising an elastic sealing between a joint of adjacent radial surfaces for limiting liquid flow between the inner volume and the filling layer and taking up thermal expansion of the modular wall parts, and said filling layer comprising an insulating layer extending over at least part of a height of the underground energy storage, having an R value designed for providing said outer wall at a temperature of below 30 C. when said inner volume is at a temperature of at least 90 C., and a structural layer for maintaining said insulating layer and said prefab inner wall parts in position.

A container for a refrigerating machine has: a storeroom storing a stored objective; a housing chamber housing an evaporator and an evaporator fan and guiding an inside air in the storeroom to flowing back to the storeroom after passing through the evaporator; a first ventilation duct connected to the housing chamber and having a first blower fan and a first heat storage body; a second ventilation duct connected to the housing chamber and having a second blower fan and a second heat storage body; and a controller controlling the first blower fan and the second blower fan. The controller controls the first blower fan and the second blower fan and switches between (i) a mode in which an outside air inflows through the first ventilation duct, and the inside air outflows through the second ventilation duct and (ii) a mode in which an outside air inflows through the second ventilation duct, and the inside air outflows through the first ventilation duct, at a specified time interval.

A method for defrosting frozen foods by recycling the water that is used to defrost the frozen foods. Food is first placed inside of a container and then water is pumped from the bottom of the container where the water is heated and by use of a pump and natural rise of heat allowed to flow around the food.

An system and method for cooling of electronic equipment, for example a computer system, in a subsurface environment including a containment vessel in at least partial contact with subsurface liquid or solid material. The containment vessel may be disposed in a variety of subsurface environments, including boreholes, man-made excavations, subterranean caves, as well as ponds, lakes, reservoirs, oceans, or other bodies of water. The containment vessel may be installed with a subsurface configuration allowing for human access for maintenance and modification. Cooling is achieved by one or more fluids circulating inside and/or outside the containment vessel, with a variety of configurations of electronic devices disposed within the containment vessel. The circulating fluid(s) may be cooled in place by thermal conduction or by active transfer of the fluid(s) out of the containment vessel to an external heat exchange mechanism, then back into the containment vessel.

A tube connection assembly includes a first connector along a connection axis having a first engagement surface transverse to the connection axis, and a second connector connected to a tube, the second connector having a second engagement surface transverse to the connection axis. The first connector and the second connector are engagable together joining the first and second connectors in a coupled state, the first engagement surface and the second engagement surface spaced a predetermined distance when in the coupled state. A fastener is provided positionable in a locked state and an unlocked state, the fastener in the unlocked state being slidable along the tube, and the fastener in the locked state retaining the first engagement surface and the second engagement surface. The fastener may include a pair of opposing retaining surfaces spaced at least the predetermined distance, at least one of the retaining surfaces having a lead-in.
