A gas dehumidification device having two heat exchangers, each including a first and second fluid line. Each second fluid line at least partially surrounds the respective first fluid line. Each heat exchanger thermally couples a fluid in the respective heat exchanger second fluid line with a first coolant on an outside surface of the respective heat exchanger second fluid line. The gas dehumidification device further comprises a two-position valve. In a first position, a fluid comprising a higher temperature than the first and/or second coolant is conducted into the first heat exchanger first fluid line and in the second position, the fluid is conducted into the second heat exchanger first fluid line. A controller is configured to place the valve selectively into the first or second position.

A heat exchange flow path portion is formed by alternately winding two spirally-shaped first and second heat transfer walls, with a predetermined gap interposed therebetween in the radial direction of the flow path pipe, around the outer periphery of a cylindrical flow path pipe, in which a cooling heat source is disposed in a main heat transfer flow path inside thereof. An inlet flow path and an outlet flow path for introducing compressed air into the flow path pipe and discharging compressed air from the flow path pipe are alternately formed, in the radial direction, from the gap between the heat transfer walls. Heat exchange is performed between compressed air that flows in the flow path and compressed air that flows in the flow path.

An air-cooled condensing heat exchanger system (“ACHX”) installed in a fossil power plant flue gas treatment system recovers water and low temperature waste heat from boiler flue gas for advanced coal fired power plant applications. More particularly, the ACHX system recovers water from combustion flue gas by phase change. To recover water from flue gas, the ACHX system uses ambient air from an air intake installed on the stack to cool down the flue gas in the ACHX.

Herein is disclosed a dehumidifier for dehumidifying ambient air in an airstream from an inlet to an exhaust from an outlet in a housing. The dehumidifier comprises an evaporator having an evaporator downstream face and an evaporator upstream face; and downstream 5 from the evaporator a condenser having a condenser downstream face and a condenser upstream face. The dehumidifier further has a thermosiphon arrangement configured to be arranged with a thermosiphon evaporator part upstream from the evaporator and a thermosiphon condenser part upstream from the condenser and downstream from the evaporator. The thermosiphon arrangement comprises a thermosiphon block configured for a refrigerant to communicate between a first header and a second header interconnected with a fluid communicator arrangement being multiple tubes, wherein the thermosiphon block is sealed and contains the refrigerant.

An apparatus for the vacuum packaging of food, which includes a base structure which defines a vacuum chamber which can be connected to a vacuum pump. Between the vacuum chamber and the vacuum pump, at least one air filtration device is provided which has elements for varying at least one thermo-fluid dynamics parameter of the flow of air extracted from the vacuum chamber by the vacuum pump, in order to enable the elimination, from the air extracted from the vacuum chamber, of water, biochemical liquids and biological materials.

A liquid desiccant air-conditioning system provides a uniform liquid desiccant flow distribution and wetting out of membranes used in the membrane-modules of the system.

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.

A heat exchanger module unit that provides heat exchange between a fluid and a heat medium by indirect heat exchange through a phase-change material disposed between movement paths of the fluid and the heat medium movement paths, includes: a multiple number of plates having a partition, which is formed with a through-hole through which the fluid and the heat medium move, are stacked with a spacing gap, through which the fluid and the heat medium move, at one side of the partition; the spacing gaps are selectively connected through a connector connecting the respective through-holes so as to form a fluid passage and a heat medium passage through which the fluid and the heat medium move independently respectively; the spacing gap, in which the phase-change material is received, is located and disposed between the spacing gaps forming the fluid passage and the heat medium passage through which the fluid and the heat medium move respectively such that heat exchange is made between the fluid and the heat medium through the phase-change material. One of the fluid and the heat medium is disposed at one side of the phase-change material and another phase-change material is disposed at the opposite side thereof.
