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. These operating parameters are provided to a computer, which stores predefined operating parameters for a plurality of cooling systems. The computer compares the provided operating parameters of the monitored cooling system with the predefined operating parameters to provide diagnostic results for the monitored cooling system and possible service procedures. If the computer does not recognize the monitored cooling system identifier, a connection is made to a master computer in order look up the predefined operating parameters in a master data base.
