The invention relates to a counter flow enthalpy exchanger (1) having a parallelogram-shaped central part (11), whose ends in the flow direction through the exchanger it is joined by end parts (12, 13), which become narrower in the direction from the central part (11), whereby in order to separate the flow of the heat-transfer medium in the direction from the inner space to the outer space are arranged contour identical and with respect to the flowing medium sealed vapour-permeable lamellae (10) with shaping means for generating turbulent flow, whereby every two adjacent lamellae (10) form one interplate flow channel in the central part (11) one interplate flow channel. The lamella (10) is made as a one-piece self-supporting moulding common to the central part (11) and the end parts (12, 13), whereby it does not have a reinforcing support grid. Two adjacent lamellae (10) form one interplate flow channel in the end part (12, 13), in the walls of which are formed straight protrusions (121, 131) situated in the direction of the heat-transfer medium flow between the central part (11) and corresponding inlet or outlet of this medium.

A heat exchanger for heat exchange between at least two fluids includes a plurality of heat exchange elements each having at least one fluid-guiding path for conducting at least one of the fluids through. The heat exchanger has a cylindrical shape or substantially cylindrical shape with a cylinder axis around which the heat exchange elements are adjacently arranged. At lease a region of each of the heat exchange elements forms an outline structure at least substantially like one of a triangular cylinder, a trapezoidal cylinder, a circle-sector cylinder, and an annulus-sector cylinder. As a result of adjacent arrangement of the heat exchange elements, the heat exchanger or at least a region of the heat exchanger has an outline structure at least substantially like one of a polygonal cylinder, a polygonal hollow cylinder, a circular cylinder, and annular cylinder. The cylindrical shape of the heat exchanger may alternatively be a cone frustum. The heat exchanger may be incorporated into an air device.

The system and method for a green integrated electric power plant mounted on rooftops, includes platform on which installed low body and upper body with gap. There are no rotatable parts for generating electric power except the propeller of generator which is affected by three air flows. The generator with propeller placed inside of upper body vertically. Low body has inside tube and spirals. Also low body has a few windows. Each window supplied by tangential plate for creating confined vortex. Thus one wind flow acting through low body directly on propeller, second air flow move warm air flow from source of warm air such as laundry or boiler room of building through conduit, inner tube and multiple Venturi tubes also act as a propeller. Third wind air flow moves perpendicular to vertical axes of generator and goes through gap between low body and upper body directly on propeller.

Provided is a solvent separation method and a solvent separation apparatus that make it possible to efficiently retrieve the thermal energy possessed by an exhaust atmosphere released in a solvent-removal step to suppress reductions in a temperature of the exhaust atmosphere. In the solvent separation method and the solvent separation apparatus, a vaporized solvent is removed from a gas while heat-exchange between the gas within a condensation part and the gas within a dust-collection part is conducted by using a heat exchange part that is placed between the condensation part that introduces the gas into a first direction and the dust-collection part that introduce the gas into a second direction opposite to the first direction the gas discharged from a downstream side of the condensation part.

The invention relates to an exchanger device comprising a first and a second end piece (1, 2) and an exchanger body (3, 4) arranged in-between. At least one first and one second channel (150, 151) in the exchanger body (3, 4) connect inlets and outlets (10, 11, 20, 21) of the two end pieces (1, 2), wherein the inlets and outlets (10, 11, 20, 21) are arranged in end faces of the end pieces (1, 2), which face away from the exchanger body. The exchanger body forms a multi-helix, in particular a double helix or multiple concentric ring surfaces, wherein the windings of the multi-helix or the concentric ring surfaces form separating walls (3, 4) between the at least one first and the at least one second channel (150, 151). The device according to the invention allows for the formation of exchanger devices with high efficiency yet also with a small outer diameter. The manufacturing process is also simplified.

A method uses a sheet shaped member to separate two spaces from each other. The sheet shaped member includes a base having a first principal surface and a second principal surface, and a moisture permeable membrane provided on or close to the first principal surface of the base. The first principal surface of the base is arranged in one of the two spaces having a lower water vapor pressure when the two spaces separated from each other by the sheet-like member have different water vapor pressures.
