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 refrigerator comprises a main body including a suction port and a plurality of discharge ports; a storage compartment formed inside the main body; a thermoelectric element to supply cold air to the storage compartment while discharging heat generated; a heat sink receiving the heat from the thermoelectric element; a blowing fan below the heat sink to cool the heat sink; and a scroll housing to accommodate the blowing fan, the scroll housing including an inlet through which air from the suction port to the blowing fan. The scroll housing includes a linear portion which forms a part of the inlet, the linear portion is formed perpendicular to the flow direction of air passing through the heat sink, and air that has passed through the blowing fan is respectively discharged in several directions through the plurality of discharge ports.

A partitioning member for a total heat exchange element includes a sheet shaped porous base, a moisture permeable membrane provided on the porous base, and a functional material. The functional material produces at least one of an antifungal effect, an antibacterial effect, and an antiviral effect. The moisture permeable membrane contains the functional material. Alternatively, a partitioning member for a total heat exchange element includes a functional membrane containing a functional material producing at least one of an antifungal effect, an antibacterial effect, and an antiviral effect, with the functional material covering a surface of the porous base or the moisture permeable membrane.

A method of operating a heating device includes heating air in a heating device chamber. The method further includes exhausting outgoing air from the heating device chamber via a first flow path through which the outgoing air flows in a first direction, and supplying incoming air to the heating device chamber via a second flow path through which the incoming air flows in a second direction opposite to the first direction. The latent heat in the outgoing air in the first flow path is transferred to the incoming air in the second flow path thereby condensing water vapor contained in the outgoing air to produce liquid water.

A micro-climate control system includes a thermoelectric system integrated with a fan assembly. The thermoelectric system is operable to actively cool or heat air as the air passes through the fan assembly. The thermoelectric system includes a thermoelectric heat pump, a heat reject subsystem, and a heat accept subsystem. The fan assembly is operable to draw air from a space to be conditioned and output conditioned air passed through one of the heat reject subsystem and the heat accept subsystem to the space to be conditioned and output air passed through the other away from the space to be conditioned. In this way, the micro-climate control system may provide localized comfort, while allowing a larger climate control system to maintain a more efficient temperature set point. In this way, the overall energy consumption may be reduced while providing the same level of effective comfort.
