; ; ;
The Research Department of the Columbia Gas System Service Corporation has developed a personal-computer-based site data acquisition system (DAS), and a modular data acquisition software package, including specific modules for acquisition of data from gas-engine heat pumps, and real-time calculation of COP. The DAS hardware and software have been implemented at 12 field-test sites nationwide, acquiring data from 1.8RT - 4RT gas-engine heat pumps. The DAS consists of an IBM personal computer (or 100% compatible clone); MetraByte data acquisition, counter/time and analog multiplexer/amplifier boards, EDA constant-current power supply and pulse train Debounce boards; and a Hayes 1200 baud modem. The software consists of the Columbia-designed, modular data acquisition, engineering unit conversion, data analysis, data display and data storage routines, and KTALK file dispatcher with bi-directional communication and error checking routines. The system stores operating system, data acquisition/analysis and communications software on one floppy-disk drive, and stores data in 60-kb data blocks on a second floppy-disk drive. The system scans up to 138 sensors every 15 seconds, and stores averaged data to disk every 15 minutes, or on every change in heat-pump operating mode.
