Type of article: Article

Summary

A COMPUTER SIMULATION WAS USED TO EXAMINE THE EFFECTS OF ERRORS IN THE SENSORS OF AUTOMATIC CONTROLS FOR HVAC SYSTEMS. COMPUTER CALCULATIONS USING THE BLAST PROGRAM INDICATE THAT SENSOR ERRORS CAN INCREASE THE ANNUAL ENERGY REQUIREMENTS ATTRIBUTABLE TO AN AIR HANDLING SYSTEM BY AS MUCH AS 30 TO 50 PER CENT. ERRORS IN THE MIXED AIR TEMPERATURE SENSOR AND THE COOLING COIL SENSOR APPEAR TO BE CRITICAL FOR THE TYPE OF HVAC STUDIED. THE BUILDING SELECTED FOR THIS STUDY WAS AN OFFICE BUILDING OF LIGHT WEIGHT CONSTRUCTION IN WASHINGTON. E.W.S.
