Abstract

Claims (51)

1. A method for managing environmental conditions of an information handling system (IHS), comprising:

making a first determination that increased cooling provided by a cooling system associated with the IHS is needed to maintain a temperature set point;

identifying, in response to the first determination, a first compressor in a compressor array, wherein the cooling system comprises the compressor array, and wherein compressors in the compressor array are organized in an order;

making a second determination that the first compressor in the compressor array is already running;

based on the second determination:

identifying a second compressor in the compressor array, based on the second compressor being after the first compressor in the order;

making a third determination that the second compressor is available; and

starting, based on the third determination, operation of the second compressor;

making a fourth determination that reduced cooling provided by the cooling system is needed to maintain the temperature set point;

identifying, in response to the fourth determination, a third compressor in a compressor array, wherein the third compressor is after the second compressor in the order;

making a fifth determination that the third compressor in the compressor array is not running;

based on the fifth determination:

identifying the second compressor in the compressor array, based on the second compressor being before the third compressor in the order;

making a sixth determination that the second compressor is running; and

stopping, based on the sixth determination, operation of the second compressor.

2. The method of claim 1 , wherein the first compressor and the second compressor are arranged in parallel.

3. The method of claim 1 , wherein the first compressor and the second compressor are arranged in series.

4. The method of claim 1 , wherein the first compressor is associated with a first cooling circuit and the second compressor is associated with a second cooling circuit.

5. A cooling system for an information handling system (IHS) comprising:

a plurality of compressors; and

a processor programmed to:

make a first determination that increased cooling provided by a cooling system associated with the IHS is needed to maintain a temperature set point;

identify, in response to the first determination, a first compressor in a compressor array, wherein the cooling system comprises the compressor array, and wherein compressors in the compressor array are organized in an order;

make a second determination that the first compressor in the compressor array is already running;

based on the second determination:

identify a second compressor in the compressor array, based on the second compressor being after the first compressor in the order;

make a third determination that the second compressor is available; and

starting, based on the third determination, operation of the second compressor;

make a fourth determination that reduced cooling provided by the cooling system is needed to maintain the temperature set point;

identify, in response to the fourth determination, a third compressor in a compressor array, wherein the third compressor is after the second compressor in the order;

make a fifth determination that the third compressor in the compressor array is not running;

based on the fifth determination:

identify the second compressor in the compressor array, based on the second compressor being before the third compressor in the order;

make a sixth determination that the second compressor is running; and

stop, based on the sixth determination, operation of the second compressor.

6. The cooling system of claim 5 , wherein the first compressor is associated with a first cooling circuit and the second compressor is associated with a second cooling circuit.

7. A non-transitory computer readable medium comprising computer readable program code, which, when executed by a computer processor enables the computer processor to perform a method for managing environmental conditions of an information handling system (IHS), the method comprising:

making a first determination that increased cooling provided by a cooling system associated with the IHS is needed to maintain a temperature set point;

identifying, in response to the first determination, a first compressor in a compressor array, wherein the cooling system comprises the compressor array, and wherein compressors in the compressor array are organized in an order;

making a second determination that the first compressor in the compressor array is already running;

based on the second determination:

identifying a second compressor in the compressor array, based on the second compressor being after the first compressor in the order;

making a third determination that the second compressor is available; and

starting, based on the third determination, operation of the second compressor;

making a fourth determination that reduced cooling provided by the cooling system is needed to maintain the temperature set point;

identifying, in response to the fourth determination, a third compressor in a compressor array, wherein the third compressor is after the second compressor in the order;

making a fifth determination that the third compressor in the compressor array is not running;

based on the fifth determination:

identifying the second compressor in the compressor array, based on the second compressor being before the third compressor in the order;

making a sixth determination that the second compressor is running; and

stopping, based on the sixth determination, operation of the second compressor.
