Abstract: An air conditioning device includes a buck converter which comprises a switching device, an inductor, a diode and at least one capacitor. The diode is a SiC diode, and the buck converter further includes an attenuator associated to the SiC diode and a ferrite bead associated to the switching device.

Abstract: A method for controlling a compressor of a refrigeration system wherein refrigerant flow through the compressor is controlled by at least one valve, whereby the valve is opened or closed in a cycle of consecutive time intervals of an identical length, so that the valve is either completely closed or completely open during a time interval, whereby a. determining a percentage capacity for the compressor-corresponding to the current refrigeration requirement of a refrigeration location, b. determining the open time percentage of the valves over a number of time intervals, c. opening the valve for the following time interval when the ratio of the percentage capacity is greater than that of the open time percentage previously determined, and d. closing the valve-for the following time interval when the ratio of the percentage capacity is smaller than that of the open time percentage of the valves previously determined.

Abstract: The invention relates to a shrinking process for producing solid, transportable and printable containers by wrapping the articles to be packaged with a film in such a manner as to produce an overlapping section of the film ends on the base area, heating by heat exchange or convection in order to seal the free ends in the area of overlap, and finally heating in a shrinking oven, the container so produced being stabilized by the shrinking process.
