Abstract: A method for controlling a refrigerant distribution in a vapour compression system, such as a refrigeration system, e.g. an air condition system, comprising at least two evaporators. The refrigerant distribution determines the distribution of the available amount of refrigerant among the evaporators. While monitoring a superheat, SH, at a common outlet for the evaporators, the distribution of refrigerant is modified in such a manner that a mass flow of refrigerant to a first evaporator is altered in a controlled manner. The impact on the monitored SH is then observed, and this is used for deriving information relating to the behaviour of the first evaporator, in the form of a control parameter. This is repeated for each evaporator, and the refrigerant distribution is adjusted on the basis of the control parameters. The impact may be in the form of a significant change in SH.

Abstract: A water filter assembly, and a refrigerator and a water purifier having the same, including: a manifold having a inflow path through which raw water flows in and an outflow path through which filtered water flows out; a case supporting the manifold; and a filter cartridge coupled to a lower side of the case such that it is separable and connected with the outflow port of the manifold, wherein a fluid flow control unit is installed between the manifold and the filter cartridge and rotates according to a rotation of the filter cartridge, the center of the rotation is the same as the center of an outlet of the filter cartridge, and the fluid flow control unit includes a disk having a connection hole allowing the raw water inflow path and an inlet of the filter cartridge to communicate only at a certain position.

Abstract: A cooling circuit for removing waste heat from a cooling device of an electromechanical converter is provided. The cooling circuit includes a chilling medium, a cooler for extracting heat from the chilling medium, a return connecting the cooling device of the converter to the cooler and conducts warm chilling medium, a feed connecting the cooler to the cooling device of the converter and conducts cool chilling medium, and an absorption chiller for extracting heat from the chilling medium. The absorption chiller is driven by the heat of the warm chilling medium that is in the return.
