摘要:
A geothermal system includes a first circuit including a first heat exchanger exchanging heat with a controlled space, a second circuit including a second heat exchanger exchanging heat with an outdoor temperature sink that varies seasonally, a geothermal heat exchanging assembly arranged to exchange heat between a geothermal source and the fluid in both the first and second circuits and a pumping device allowing the first circuit to function as a heat pump. The flow in both the first and second circuits is seasonally reversible to alternately heat or cool the controlled space. An expansion motor connected in series with the second circuit in communication between the second heat exchanger and the geothermal heat exchanging assembly is driven by expansion of fluid in the second circuit to function as a Rankine cycle in either seasonal direction of the flow to power the pumping device in both seasonal directions.

A space-saving, high-density modular data pod system and an energy-efficient cooling system are disclosed. The modular data pod system includes a central free-cooling system and a plurality of modular data pods, each of which includes a heat exchange assembly coupled to the central free-cooling system, and a distributed mechanical cooling system coupled to the heat exchange assembly. The modular data pods include a data enclosure having at least five walls arranged in the shape of a polygon, a plurality of computer racks arranged in a circular or U-shaped pattern, and a cover to create hot and cold aisles, and an air circulator configured to continuously circulate air between the hot and cold aisles. Each modular data pod also includes an auxiliary enclosure containing a shared fluid and electrical circuit section that is configured to connect to adjacent shared fluid and electrical circuit sections to form a shared fluid and electrical circuit that connects to the central free-cooling system. The auxiliary enclosure contains at least a portion of the distributed mechanical cooling system, which is configured to trim the cooling performed by the central free-cooling system.

A refrigerator in which a refrigerant pipe assembly including a refrigerant pipe and a refrigerant pipe insulator coupled to the refrigerant pipe is inserted into an inner case in an inward direction from an outside of the inner case through an opening of the inner case. 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. The refrigerant pipe insulator portion disposed between the inner case and the outer case is supported by a body insulator foamed between the inner case and the outer case. In accordance with this structure, it is possible not only to insulate the refrigerant pipe, but also to easily insert the refrigerant pipe into the ice making chamber and to keep the refrigerant pipe in a firmly-supported state.
