1. An apparatus comprising:
- a first sensor for sensing a first cooling system operating parameter;
a second sensor for sensing a second cooling system operating parameter;
a third sensor for sensing a motor operating parameter; and
a computer including data sets of normal operating parameters for a plurality of cooling systems stored in a memory and receiving system configuration information data for an individual cooling system, said computer selecting one of said data sets of normal operating parameters based on said received system configuration information data and comparing said first cooling system operating parameter, second cooling system operating parameter, and motor operating parameters with said selected normal operating parameters to diagnose a cooling system.

Abstract
A data acquisition system and method includes monitoring a cooling system having a refrigerant compressor, evaporator, and condenser, and employs a number of sensors to monitor various operating parameters of the system. A database stores predefined operating parameters for a plurality of cooling systems. The operating parameters are provided to a computer, which compares the provided operating parameters of the monitored cooling system with the predefined operating parameters to provide diagnostic results for the monitored cooling system.
