Abstract: The invention relates to a heatable floor for livestock stalls comprising a plurality of hollow, right-angled plate elements whose hollow spaces are filled with a heat transfer fluid and can be heated by means of heating lines (11) running through the hollow spaces, wherein each plate element comprises one upper shell (1) having an inlet opening (5) and forming a standing surface for the livestock and one lower shell (7) supporting the upper shell (1), the shells being connected to one another liquid-tight at their edges and having means for suspending carriers and being supported on one another by supports (6, 9) that run through the hollow space.

Abstract: The invention relates to a method for the storage of deep-frozen goods in a freezer having a speed-controlled compressor. In accordance with the invention, the compressor is operated in long-term operation and the temperature is lowered in a low-temperature mode to a temperature which is clearly below ?18° C., and is kept substantially constant at this selected temperature with only low temperature fluctuations which are caused by a change in speed of the compressor.

Abstract: The present invention relates to a refrigerator and/or freezer, comprising a liquefier, an evaporator and a compressor, wherein the refrigerator and/or freezer includes means by which a pressure compensation between liquefier and evaporator is prevented or slowed down during the standstill of the compressor, and that the refrigerator and/or freezer includes a means for effecting the compressor start-up, wherein the means for effecting the compressor start-up comprise means for increasing the starting torque of the compressor and/or means for increasing the starting current of the compressor motor and/or means which ensure that the crank shaft of the compressor stops in a preferred position after shutting off the compressor motor, and/or means for the at least partial pressure compensation between the pressure side and the suction side of the compressor and/or means for reducing the initially required starting torque.
