A method of connecting a heat exchanger, which is used primarily in oil and gas operations to heat tanks of liquids, such as drilling mud, water, heavy oil or other such fluids from freezing or becoming too viscous to pump, to a tank.

A reservoir tank for use in a nuclear reactor building includes a reservoir tank in which cooling water is stored. A partition part is disposed in the reservoir tank and partitions the inside of the reservoir tank into a first storage tank and a second storage tank so as to separate the cooling water in the reservoir tank. An inflow part is disposed in the partition part and allows the cooling water of the second storage tank to naturally flow into the first storage tank by the difference between the water levels of the first and second storage tanks when the water level of the first storage tank is lowered. This configuration is advantageous in that a nuclear reactor does not need to be pressurized and reheated when the nuclear reactor building is cooled due to a severe accident.

The disclosure relates to devices and methods for ventilating enclosed area such as shipping containers or structures erected to temporarily contain cargo items. A central element in such devices and methods is a ventilation stack assembly in which a vertically-oriented stack having an outlet is connected at its other end to a pipe leading to an inlet. A first housing having the dimensions (and preferably the fittings) of a standard shipping container is rigidly connected to the stack and pipes, and the assembly can be physically manipulated as if it were a standard shipping container. Gas (e.g., fumigant) provided to the pipe inlet passes through the pipe and into and through the stack, exiting at the outlet, which can be situated at an altitude whereat gas discharged therefrom is dispersed into the atmosphere at a location and concentration at which displeasure or hazard to humans can be reduced.

The invention relates to a floor (10) for a container, the floor comprising at least one section (11,11′,11″) is, wherein the floor section (11,11′,11″) is formed from a single sheet element and includes a number of protruding elements (20′, 20″, 20″) and a base (28), the floor section (11,11′,11″) has a polygonal shape with a length (L) extending in a first direction (X) and a width (W) extending in a second direction (Y) being perpendicular to the first direction (X), each protruding element (20, 20′, 20″) includes a base element having two side walls (22,23) extending perpendicularly from a base (28) of the floor section (11,11′,11″). The invention further relates to a method of manufacture of a floor section (11, 11′, 11″) for a container floor (10).

Systems and methods can control refrigeration within a refrigerated freight container. Thermal sensor nodes can be positioned within the freight container. Temperature measurements can be wirelessly relayed from the sensor nodes to a gateway associated with the freight container. The received temperature measurements can be aggregated and logged at the gateway. Thermal models of the freight container and associated cargo loads can be established in response to the logged temperature measurements and loading plan for the foreign container. The refrigeration system can be controlled in response to processing the thermal models. The refrigeration system can be controlled to optimize compliance parameters associated with the cargo loads.

A refrigerated storage container is provided and includes a container housing defining an interior, an air conditioner operable to maintain control of temperatures within the interior and a local controller configured to cycle the air conditioner on and off within a time window based on waste heat ingestion from neighboring refrigerated storage containers.

A powder container (10) comprising a pressure vessel (12) for containing a quantity of powder (14) and a quantity of pressurised gas (32), an outlet through which, in use, the powder (14) can flow out of the pressure vessel (12), and an outlet valve (24) for selectively opening and closing the outlet, wherein the container (10) further comprises a data sensing and/or logging means (56, 58, 60, 62, 64) adapted to monitor and/or log various parameters of the powder (14) and/or the pressurised gas (32) and further comprising a control unit (54) adapted record and log the sensor readings either continuously, or at intervals, the control unit (54) comprising a communications module adapted to relay sensor readings, or log files, to a remote monitoring station.

An energy storage system includes a plurality of battery strings, each battery string including a plurality of batteries coupled electrically together; a plurality of temperature sensors; an enclosure housing the plurality of battery strings and the temperature sensors; a plurality of fans positioned in different locations within the enclosure; and a temperature control system. The temperature control system includes a heating, ventilation, and air conditioning (HVAC) components, and a controller. The controller is programmed to execute the method that includes determining fan speed operating commands based at least in part on sensed temperatures at the different locations, and operating the fan speed in response to the operating commands provided to the respective fans.
