1. A cooling device (1) comprising more than one cabinet (2, 102, 202) wherein items to be cooled are placed and which are positioned separately, a compressor (5) positioned into a chamber separately from the cabinets (2, 102, 202) and providing a cooling cycle to be performed, and more than one val
1. A cooling device (1) comprising more than one cabinet (2, 102, 202) wherein items to be cooled are placed and which are positioned separately, a compressor (5) positioned into a chamber separately from the cabinets (2, 102, 202) and providing a cooling cycle to be performed, and more than one valve (6, 106, 206) providing a determination to which cabinet (2, 102, 202) and in which amount the refrigerant pumped from the compressor (5) will be directed, a cabinet card (3, 103, 203) located on each cabinet (2, 102, 202), wherein the cabinet card located on each cabinet includes a dip switch which sends a sequential logic signal according to an on/off positions of the dip switches, a main board (4), including storage of a memory of the sequential logic signal for each type of cabinet (2, 102, 202) and storage of a corresponding cooling algorithm, the main board adapted to detect the cooling algorithm that corresponds to the sequential logic signal coming from the cabinet card (3) according to the data stored in its memory, and the main board (4) adapted to apply the cooling algorithm stored in its memory corresponding to the logic signal related to each cabinet (2, 102, 202) and thus to control the compressor (5) and the more than one valve (6, 106, 206) in accordance with the cooling algorithm corresponding to the sequential logic signal coming from the cabinet card (3, 103, 203). 2. The cooling device as in claim 1, wherein the main board (4) receives the sequential logic signal corresponding to the on/off positions of the dip switches from each cabinet card (3, 103, 203) after each electricity failure and updates the cabinet data (2, 102, and 202) to the sequential logic signal corresponding to the on/off positions of the dip switches from each cabinet card (3, 103, 203) received. 3. The cooling device as in claim 1 or 2, further comprising a communication indicator (7) indicating whether there is communication between the cabinet cards (3, 103, 203) and the main board (4). 4. The cooling device (1) as in claim 3, wherein the communication indicator (7) comprises LEDs glowing green and red, wherein the green LED therein glows if the communication between the cabinet cards (3, 103, 203) and the main board (4) can be realized properly and wherein the red LED therein glows if the communication cannot be realized properly. 5. The cooling device (1) as in claim 1 or 2, further comprising a cabinet indicator (8, 108, 208) located on each cabinet (2, 102, 202) between the cabinet cards (3, 103, 203) and the main board (4). 6. The cooling device( 1) as in claim 5, wherein the cabinet indicator (8, 108, 208) comprises LEDs glowing green and red, wherein the green LED therein glows if the communication between the cabinet cards (3, 103, 203) and the main board (4) can be realized properly and wherein the red LED therein glows if the communication cannot be realized properly. 7. The cooling device (1) as in claim 1 or 2, wherein the main board (4) can set each cabinet (2) to a safe mode if the control card (3) related to the cabinet cannot communicate with the main board (4) by closing the valve (6) transferring refrigerant to the cabinet (2) having the cabinet card (3) which cannot communicate with the main board.
