A refrigerator includes a main body that has a storage chamber and a drying chamber; a thermoelectric module that includes a heat absorber and a heat dissipater; a cooling fan that circulates air in the storage chamber to the heat absorber and the storage chamber; a heat-dissipating fan that blows air to the heat dissipater; an air guide that has a passage for guiding air heated by the heat dissipater to the drying chamber; a heater that is disposed in the passage; and a damper that controls a flow of air in the passage between the heat-dissipating fan and the heater. Heat of the heat dissipater transfers to the drying chamber through the passage of the air guide and the damper, thereby being able to dry an object to be dried.

A Step Flow control device and methods therefore provide instructions to control operation of various absorption chiller components based on measured load or temperature information. Operating an absorption chiller according to Step Flow balances the flow of heat energy through the absorption chiller to increase efficiency and prevent crystallization. The control device may be integrated into various components of an absorption chiller or may be remote therefrom. In this manner, Step Flow can be used in new absorption chiller installations or be used to retrofit existing installations.

The system comprises a plurality of first fluidic flow channels and a distribution device fed by a flow of a first fluid, notably a liquid, and injecting the flow of first fluid into the plurality of first channels at an output of the distribution device. The output of the distribution device consists of an distribution element for the first fluid, notably formed in a porous material, configured in such a way as to be passed through by the first fluid with a pressure drop such that the first fluid leaves from the distribution element with a uniform surface distribution at an output surface of the distribution element, in a way that ensures a uniform feed of first fluid for the first channels.
