Abstract: The subject of this invention is a method of heat transfer in the embedded structure of a heat regenerator and the design thereof. It regards the related heat regenerators, which operate on the principle of the described method and enable a reduction of the pressure drop due to the fluid flow through the heat regenerator and consequently an increase of the power density. The concept of the operation of the heat regenerator by this invention, in which for the oscillation of the flow of the primary (first) fluid (P), electromechanical elements are applied. In the housing (1) between the elements (2) for the oscillation of the primary (first) fluid (P), there are positioned a primary hot heat exchanger (PT) and a primary cold heat exchanger (PH). In the direction of the arrow (A) the unidirectional flow of the secondary (second) fluid (S) flows from the heat sink into the primary cold heat exchanger (PH).

Abstract: The present invention refers to an improved cooling system for a refrigerator, preferably a domestic refrigerator, comprising a cell in which is located at least one compartment for the storage of food below freezing point, with said compartment being cooled using at least one wire tube evaporator arranged on at least one wall of said cell. It is provided for according to the invention that a wire tube evaporator (3, 4, 5) arranged inside said cell (1) is hydraulically connected to a tube evaporator (7), which extends in a manner similar to a coil (6) along the outer periphery of said cell (1).

Abstract: The present invention refers to a system for vertically adjusting a shelf, such as in refrigerating appliances, cabinets, lockers and similar, said shelf comprises horizontal support members (10, 11) arranged perpendicularly to vertical guides (1, 2) where they can be vertically adjusted, and a deposit plate (12), a drawer or similar, being attached to said horizontal support members (10, 11). The invention is based on a fact that said shelf is fixed in a form-locking and friction-type manner in vertical guides (1, 2) by means of horizontal support members (10, 11).

Abstract: The present invention refers to a refrigerating appliance preferably for cooling of drinks, comprising a cooling section with a freezing unit arranged therein having a freezing section where an ice making device is arranged, said cooling section and/or freezing section being optionally divided into several compartments by means of partition walls, and having an evaporator for creating and supplying cold air into the freezing section and cooling section, where several cooling channels are formed in a body of the refrigerating appliance for distributing cooling air via several discharging slots into each separate compartment.
