Abstract

The present invention relates to 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 ) providing the cooling cycle to be performed, and more than one valve ( 6, 106, 206 ) providing the refrigerant pumped from the compressor ( 5 ) to be determined, to which cabinet ( 2, 102, 202 ) and in which amount it will be directed.

First claim

The invention claimed is:

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.
