Embodiment Construction

[0025] exist figure 1 In the control loop according to the prior art shown in , the target value for the internal appliance housing temperature is provided as an input signal to the regulator. The regulator can be, for example, a PID controller. The PID controller determines a manipulated variable according to the cooling technology for air-conditioning the appliance housing, for example based on a device characteristic characterizing the refrigerant circuit, wherein the manipulated variable is transmitted to the regulating device in the form of a drive signal. The conditioning device may be, for example, a refrigerator or a heat pipe arrangement.

[0026] If the regulating device is a refrigerator, the manipulated variable can be, for example, a compressor speed or at least one fan speed of at least one fan. Compressor and fan speeds are adjustable. The regulator determines the manipulated variable on the basis of the available device characteristics such that the regulati...

Abstract

The invention relates to a regulation method for an appliance enclosure cooling device having a refrigerator and a heat pipe arrangement, the method comprising the steps of: measuring the current internal appliance enclosure temperature and determining a target temperature for the internal appliance enclosure temperature, wherein the internal The appliance housing temperature and the target temperature form the input signal of the regulator for driving the appliance housing cooling device, and wherein the regulator outputs a control signal for determining the manipulated variable of the refrigerator; Proportional measured variable regulator signal; in case the required cooling power is to be provided by the refrigerator or in case the required cooling power is to be provided by the heat pipe arrangement, the ambient appliance housing temperature is measured and the corresponding energy efficiency of the refrigerator and heat pipe arrangement is determined ;Select and activate which of the two refrigerant circuits provides the required cooling capacity with greater energy efficiency.

Description

technical field [0001] The invention relates to an adjustment method for a cooling device for an electric appliance casing. Background technique [0002] The appliance enclosure cooling device comprises a first refrigerant circuit with a refrigerator and a separate second refrigerant circuit with a heat pipe arrangement, wherein ambient air is led through the outer circuit of the appliance enclosure cooling device for heat dissipation and from the The air to be cooled inside the cooled appliance housing is led through an internal circuit of the appliance housing cooling device. An appliance housing arrangement with such an appliance housing cooling device is known, for example, from DE 10 2012 108 110 A1. [0003] For an energy-efficient operation of such an appliance housing cooling device, the refrigerant circuit of the two refrigerant circuits that provides the required cooling capacity more efficiently must be selected at any operating point. On the one hand, this requ...
