Type of article: Periodical article

Summary

THE MAIN TASKS OF COMPUTERS IN INDUSTRIAL REFRIGERATION ARE MONITORING, CONTROL AND COMMUNICATION, WITH MONITORING BEING THE MOST FUNDAMENTAL TASK BECAUSE WITHOUT INPUTS OF VARIOUS KINDS (MAINLY DIGITAL AND ANALOGUE), THERE WOULD BE NO INFORMATION TO COMMUNICATE OR TO APPLY TO SYSTEM CONTROL. THE ARTICLE DEALS WITH THE PRINCIPAL PARAMETERS WHICH NEED TO BE MONITORED IN INDUSTRIAL REFRIGERATION SYSTEMS: TEMPERATURE, USING VARIOUS TYPES OF SENSORS, PRESSURE, ELECTRICAL CURRENT AND POWER USING TRANSDUCERS WHICH PRODUCE A MILLIAMPERE OR MILLIVOLT SIGNAL AND, ALSO, THE RATE OF FLOW IN THE SYSTEM. MICROCOMPUTERS ARE NOW BEING USED TO MEASURE AND CONTROL FROST FORMATION ON LOW TEMPERATURE AIR COOLERS. SPECIFIC CONTROL SYSTEMS ARE ALSO DEALT WITH, SUCH AS SINGLE AND TWO-STAGE HALOCARBON SYSTEMS, LIQUID CHILLERS, TWO-STAGE AMMONIA SYSTEMS AND MULTIPLE SCREW COMPRESSOR INSTALLATIONS, THESE BEING TYPICAL APPLICATIONS FOR THE TELSTAR MICROCOMPUTER.
