Cooling system flood prevention tool

A method to prevent flooding comprising:

• removing heat from a first space proximate to a first load using a refrigerant;
• removing heat from a second space proximate to a second load using the refrigerant;
• removing heat from a third space proximate to a third load using the refrigerant;
• removing heat from a fourth space using a fourth load using the refrigerant;
• compressing the refrigerant from the fourth load using a compressor;
• detecting a first temperature of the refrigerant from the first load, the second load, and a third load using a first temperature sensor;
• detecting a second temperature of the refrigerant from the first load, the second load, the third load, and the compressor using a second temperature sensor;
• triggering an alarm if a difference between the first temperature and a saturation temperature of the refrigerant is below a first threshold for a first duration of time;
• and
• triggering an alarm if a difference between the second temperature and the saturation temperature is below a second threshold for a second duration of time.

A flood prevention system comprising:

• a high side heat exchanger configured to remove heat from a refrigerant;
• a flash tank configured to store the refrigerant from the high side heat exchanger;
• a first load configured to use the refrigerant from the flash tank to remove heat from a first space proximate to the first load;
• a second load configured to use the refrigerant from the flash tank to remove heat from a second space proximate to the second load;
• a third load configured to use the refrigerant from the flash tank to remove heat from a third space proximate to the third load;
• a fourth load configured to use the refrigerant from the flash tank to remove heat from a fourth space proximate to the fourth load;
• a first compressor configured to compress the refrigerant from the fourth load;
• a first temperature sensor configured to detect a first temperature of the refrigerant from the first load, the second load, and the third load;
• a second temperature sensor configured to detect a second temperature of the refrigerant from the first load, the second load, the third load, and the first compressor;
• and
• a controller configured to:
• trigger an alarm if a difference between the first temperature and a saturation temperature of the refrigerant is below a first threshold for a first duration of time;
• and
• trigger the alarm if a difference between the second temperature and the saturation temperature is below a second threshold for a second duration of time.
