Definitions
- Refrigeration appliance in particular domestic refrigeration appliance, and method for controlling a refrigeration appliance
- the invention relates to a refrigeration device, in particular household refrigerating appliance, according to the preamble of claim 1 and a method for controlling such a refrigerating appliance according to claim 9.
- the cooling performance that is the time required to cool newly introduced into the refrigerator food from an ambient temperature to the storage temperature plays an increasingly important role.
- electronically controlled refrigerators have a so-called super-cooling function, in which a normal refrigeration compartment temperature is lowered to the coldest regulator setting for a predetermined period of time and then normal operation takes place again.
- the cooling power introduced into the refrigerator can be controlled by switching on and off of the compressor.
- the generic refrigerator has a cooling fan, which can generate an air flow in the refrigerator.
- the control device can be controlled in a first operating mode to a first desired temperature and in a second mode, such as the above-mentioned super-cooling function, be controlled to a second reduced target temperature.
- the object of the invention is to provide a refrigeration device and a method for controlling such a refrigeration device, in which the cooling capacity is increased without increasing the total energy consumption significantly.
- the object of the invention is solved by the features of claim 1 or claim 9. Advantageous developments of the invention are disclosed in the subclaims.
- the fan controlling the control device is designed so that in the second mode, a time interval of the fan overlaps at least partially a Stehzeitintervall of the compressor in time.
- the cooling capacity can be specifically increased only in the second operating mode, that is to say when the super-cooling function is activated, while the cooling capacity remains the same during normal operation. This means that in normal operation no additional increase in the energy consumption of the refrigeration device takes place.
- the cooling performance increase takes place only in the second operating mode, while in normal operation the fan can remain switched off in the compressor idle time.
- the additional running times of the fan according to the invention are therefore limited only to the second mode, so that a permanent increase in the energy consumption of the refrigerator can be avoided.
- the runtime interval of the fan during the second mode of operation may be greater than the runtime interval of the compressor. This ensures that the runtime interval of the fan overlaps both the transit times and idle times of the compressor.
- the cooling space of the refrigeration device together with the introduced refrigerated goods form a controlled system whose actual temperature is detected by means of the refrigerator space sensor and conducted to the control device. As soon as the detected actual temperature is greater than a switch-on temperature predetermined by the control device, the control device switches on the compressor, whereby a cooling power is introduced from the evaporator into the cooling space. If the actual temperature drops below a predetermined switch-off temperature, the control device switches off the compressor.
- the response of the controlled system formed by the cold room and chilled goods is accelerated by connecting the fan, that is, the inertia of the controlled system is reduced. This means that when goods are introduced through the air flow generated by the fan, the heat transfer from the newly introduced product to the cold room sensor is intensified, which consequently shortens the period of time until the compressor is switched on again.
- control device may preferably control the fan such that its transit time interval not only temporally overlaps the idle time interval of the compressor, but also at least partially overlaps the runtime interval of the compressor. In this way, even when the compressor is switched on, the inertia of the existing refrigerated space and imported goods controlled system can be reduced. This means that the cooling of the new goods introduced into the cold room is also accelerated during the cooling phase.
- the second operating mode can be activated by manual operation of an input element by a user in the manner of the super-cooling function known per se. Such activation can usually take place after a goods introduction, in which the newly introduced product is to be cooled from the ambient temperature to the cold room temperature in a shortened time.
- the runtime interval of the fan can correspond substantially to the entire operating time of the second operating mode.
- the control device can according to a predetermined
- the second mode automatically returns to the first mode, ie to normal operation, switch over.
- the fan runs in the second mode in continuous operation.
- the fan In contrast to the second operating mode can be dispensed with in the first mode to such a continuous operation of the fan in favor of reduced energy consumption.
- the fan In the first operating mode, the fan can be switched on only when the compressor is activated, that is, in the cooling phase, in order to keep the fan running time as low as possible for reasons of energy saving. In the first operating mode, therefore, the fan operation is coupled to the compressor operation.
- the fan in the second operating mode, the fan can be actuated by the control device independently of the standing / running times of the compressor.
- Fig. 1 in a side sectional view of a refrigeration device
- Fig. 2 shows the time course of the actual temperature of the cooling chamber with the Radiostän- the compressor and the fan.
- FIG. 1 a refrigeration device with a cooling space 3 is roughly schematically shown in a schematic representation, which is divided into four cooling compartments 6 by means of three horizontal floors 5.
- the refrigerator 3 is closed with a door 7 front. Both the appliance door 7 and the walls delimiting the cooling space 3 are designed to be heat-insulating in a known manner.
- the refrigerator is associated with a known refrigerant circuit 1 1, in which an evaporator 9, a compressor 13 and a condenser 15 is connected.
- the refrigerant circuit 1 1 is electronically controlled by means of a control device 17.
- the control device 17 with a refrigerator sensor 19 and the compressor 13 in signal communication.
- the refrigerator sensor 19 detects an actual temperature T
- the actual temperature T ⁇ st with user-specified predetermined target temperatures T S i, T S2 compared. Based on this comparison, the controller 17 turns the compressor 13 on or off.
- the refrigeration device is equipped with a fan 21. This is provided according to FIG. 1 within the cooling space 3 at the upper end of the evaporator 9 and generates an air flow 23 in the switched-on state.
- the refrigeration device of a designated in Fig. 2 with I first mode in which the refrigerator is running in normal mode temporarily switched to a second mode Il, in which a so-called super-cooling function is activated.
- the second mode Il can, in particular for a goods introduced into the cooling chamber 3 the user side by manual actuation of an input member 25 of the control means 17 are activated for a predetermined operating time .DELTA.t S c.
- the regulating device 17 regulates the actual temperature T
- the setpoint temperature T S i in the first mode I for example, in a range of 4 to 6 0 C.
- the Set temperature T S2 for example, at 1 0 C. In this way, the cooling capacity of the refrigerator is increased when activated super-cooling function.
- the setpoint temperatures T S i, T S2 shown are each assigned on and off temperatures T in and T out .
- the control device 17 turns on the compressor 13 as soon as the actual temperature T ⁇ st the respective switch-on temperature T exceeds .theta..sub.M. In contrast, the control device 17 turns off the compressor 13 as soon as the actual temperature T ⁇ st the switch-off temperature T from below.
- the control device 17 controls the compressor 13 and the fan 21 such that the operation of the compressor 13 and the operation of the compressor 13 are controlled. drive the fan 21 is coupled. This means that the time intervals .DELTA.t S i of the compressor 13 coincide with the time intervals .DELTA.t S2 of the fan 21 in time.
- the user presses the input element 25 at time t 0 , as a result of which the control device 17 controls the refrigeration device for the operating time ⁇ t S c in the second operating mode II.
- the fan 21 runs according to the invention in continuous operation.
- the operation of the fan 21 is therefore in the second mode Il - in contrast to the first mode - decoupled from the operation of the compressor 13. Accordingly, the fan 21 in the second mode Il also during the idle time intervals .DELTA.t S i of the compressor 13 in operation.
- the solution according to the invention does not lead to a permanent increase in energy consumption of the refrigerator, but is the cooling performance when needed, that is, upon actuation of the input element 25, increased.
