Pipe arrangement for transporting temperature control media, comprising a base body which is produced by means of blow molding and from which at least a first channel and a second channel are formed, wherein the first channel and the second channel have a first orientation towards one another in a first section and a second orientation towards one another in a second section, wherein the first orientation is different from the second orientation.

A fluid vapor distillation apparatus. The apparatus includes a source fluid input, and an evaporator condenser apparatus. The evaporator condenser apparatus includes a substantially cylindrical housing and a plurality of tubes in the housing. The source fluid input is fluidly connected to the evaporator condenser and the evaporator condenser transforms source fluid into steam and transforms compressed steam into product fluid. Also included in the fluid vapor distillation apparatus is a heat exchanger fluidly connected to the source fluid input and a product fluid output. The heat exchanger includes an outer tube and at least one inner tube. Also included in the fluid vapor distillation apparatus is a regenerative blower fluidly connected to the evaporator condenser. The regenerative blower compresses steam, and the compressed steam flows to the evaporative condenser where compressed steam is transformed into product fluid.

A method of constructing a coil wound heat exchange module and transporting and installing the coil wound heat exchange module at a plant site, such as an natural gas liquefaction plant. A module frame is constructed and attached to a heat exchanger shell prior to telescoping of a coil wound mandrel into the shell. The module frame includes a lug and two saddles that remain attached to the shell throughout the process and when the heat exchanger is operated. The lug and saddles are constructed and located to stabilize the shell during construction, telescoping and transport (when in a horizontal orientation), and when the shell is installed at the plant site (in a vertical orientation). The lugs and saddles are adapted to allow for thermal expansion and contraction of the shell when it is transitioned from ambient to operating temperature and vice versa.

A heat exchanger and a method for manufacturing the same provides a double pipe heat exchanger including an outer pipe, an inner pipe forming a first fluid passage and a second fluid passage between the inner pipe and the outer pipe, first and second connecting pipes to pass fluid from the outside and exhaust the fluid by connecting ends of the outer pipe, and a connector to connect the inner pipe and each connecting pipe to the outer pipe. The connector includes expanded ends of the outer pipe and a reducing part configured to assemble the inner pipe inserted in the outer pipe with an end of each connecting pipe by forming at an end of each expanding part with a pressing process. The center line of the inner pipe connected to the connector is disposed at an upper side of the inner circumference surface of the outer pipe.

A dish washing machine including a housing having an interior wash space for washing dishes. The housing has a liquid inlet for adding a liquid to the dish washing machine. At least one rotating spray nozzle sprays the liquid onto dishes positioned within the interior wash space. The machine further includes a heating tank for heating the liquid which is supplied to the at least one rotating spray nozzle for spraying onto the dishes in the interior wash space. Two heat exchange systems are within the housing. The two heat exchange systems transfer heat from the liquid heated by the heating tank to the liquid added to the dish washing machine from the liquid inlet. A first one of the two heat exchange systems passes heat from water in the wash tank or the interior wash space to water in the first one of the two heat exchange systems.

A double pipe forms an inner flow path, through which a low-pressure side refrigerant flows, inside an inner pipe, and forms an inner-outer flow path, through which a high-pressure side refrigerant flows, between the outer pipe and the inner pipe. It comprises an expansion valve side connector and a counter-expansion valve side connector which are interposed between distal ends of the outer pipe and the inner pipe and members to be connected. An outer diameter of the outer pipe is 30 millimeters or less. A ratio of a difference between an inner diameter of the outer pipe and an outer diameter of the inner pipe with respect to the inner diameter of the outer pipe is 25% or less. A sealing member is provided to prevent a refrigerant leakage. The plurality of members are mechanically fixed.
