Abstract
A data acquisition system and method includes monitoring a cooling system having a refrigerant compressor, evaporator, and condensor, 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.
