1. A data acquisition system for monitoring a cooling system including a microcontroller, a refrigerant compressor, evaporator, and condenser, said data acquisition system comprising:

  • a computer having a memory containing predefined operating parameters and an input for receiving a monitored operating parameter, and in communication with the microcontroller to receive said monitored operating parameter;

    a first sensor in communication with the microcontroller and adapted to sense a first operating parameter of the cooling system;

    a second sensor in communication with the microcontroller and adapted to sense a second operating parameter of the cooling system; and

    a third sensor in communication with the microcontroller and adapted to sense a motor operating parameter of the cooling system;

    wherein said monitored operating parameter includes at least one of said first operating parameter, said second operating parameter, and said motor operating parameter, said computer being operable to compare said monitored operating parameter to said predefined operating parameters to diagnose the cooling system.
