A direct electric heating (DEH) system for heating a subsea pipeline is provided. The DEH system includes a subsea power cable adapted to be coupled to a three phase electric power source. The DEH system further includes two or more subsea DEH modules. Each subsea module of the two or more subsea DEH modules is provided for heating a different pipeline section of the subsea pipeline.

An air conditioning apparatus and an air conditioning method for cooling a passenger space of a vehicle that accommodates a user include a tank that is capable of storing compressed air, and a control unit to release the compressed air stored in the tank into the passenger space. Energy that is generated without putting a workload on the power source or electric power of the vehicle is used for at least one process of compressing air in the tank, cooling the compressed air stored in the tank, and heating the compressed air stored in the tank.

An anti-ice buildup system for roof vent pipes that is easy to install and that prevents ice buildup in roof vent pipes. The anti-ice buildup system for roof vent pipes generally includes a first segment and a second segment extending downwardly from the first segment. At least a portion of the first segment is adapted to remain outside of a vent pipe and at least a portion of the second segment is adapted to extend downwardly through an upper opening in the vent pipe. The second segment is constructed of a thermal conductive material to conduct heat from the vent air and sunlight.

Connector assembly, and/or motor-vehicle connector assembly, with at least one connector and at least one media line connected to the connector. The media line is electrically heated, a heat-conducting element being arranged in the transition region between connector and media line. The heat-conducting element extends with a first heat-conducting section into the media line and with a second heat-conducting section into the connector. By means of the electric heating of the media line, the heat-conducting element is heated, and/or indirectly heated, and in particular is heated and/or indirectly heated as far as the region of the connector.

An airfoil according to an example of the present disclosure includes, among other things, an airfoil body having an internal passage for conveying a fluid flow. The internal passage includes first and second passage sections coupled at a turn section. A baffle includes a body arranged in the second passage section to define two cooling flow paths, and a first wedge region extends from the body into the first passage section such that the fluid flow is directed through the turn section between the first passage section and the two cooling flow paths.

Embodiments for a cryohead heat transfer coupling as well as methods for extracting heat from an article using these couplings are provided. Couplings employ a component made from a material having a greater mean thermal coefficient of expansion than the mean thermal coefficient of expansion of other coupling components and of the article. As a result, differential contraction during cryocooling contributes a shrink fitting of a portion of the coupling resulting in enhanced thermal conduction when cooling and a releasing of the coupling when ambient temperature is restored.

A drying apparatus includes a compartment for containing objects to be dried, a closed-loop air pathway and a regeneration heat exchanger. The closed-loop air pathway includes a cooling element and a heating element, and is configured to extract from the compartment air that includes moisture in the form of vapor, to evacuate heat energy from the extracted air to an external fluid flow by cooling using the cooling element so as to remove at least some of the moisture from the air, to reheat the air using the heating element, and to re-introduce the reheated air into the compartment. The regeneration heat exchanger is inserted in the closed-loop air pathway and is configured to transfer heat from the air extracted from the compartment to the air exiting the cooling element in the closed-loop air pathway.

An unbonded flexible pipe for offshore transportation of fluids from a subsea facility. The unbonded flexible pipe has a length along a longitudinal center axis, and a first and a second end, and a first end fitting connected to the first end. The unbonded flexible pipe comprises from inside and out an electrically conductive carcass, an electrically insulating innermost sealing sheath, at least one electrically conductive armor layer comprising at least one helically wound electrically conductive wire and an electrically insulating outer sealing sheath. At least the electrically conductive layers are mechanically terminated in the first end fitting and the pipe comprises electrical connections arranged to apply a voltage over the electrically conductive layers which electrically conductive layers are electrically connected at a distance along the length of the unbonded flexible pipe from the first end fitting of the unbonded flexible pipe to provide an electric circuit.

A medical treatment system, such as peritoneal dialysis system, may include control and other features to enhance patient comfort and ease of use. For example, a peritoneal dialysis system may include a control system that can adjust the volume of fluid infused into the peritoneal cavity to prevent the intraperitoneal fluid volume from exceeding a pre-determined amount. The control system can adjust by adding one or more therapy cycles, allowing for fill volumes during each cycle to be reduced. The control system may continue to allow the fluid to drain from the peritoneal cavity as completely as possible before starting the next therapy cycle. The control system may also adjust the dwell time of fluid within the peritoneal cavity during therapy cycles in order to complete a therapy within a scheduled time period. The cycler may also be configured to have a heater control system that monitors both the temperature of a heating tray and the temperature of a bag of dialysis fluid in order to bring the temperature of the dialysis fluid rapidly to a specified temperature, with minimal temperature overshoot.
