Retrofit of Standard Analog-Electronic Control Panels at Existing Army Facilities

摘要

The U.S. Army Construction Engineering Research Laboratory (USACERL) previouslydeveloped designs and guidance documents for Standardized Heating, Ventilating, and Air-Condition in (HVAC) Control Systems. These Standard Control Systems, using analog electronic controllers, would save money be reducing energy consumption and maintenance requirements through improved control of HVAC processes and reliability of components. In this study, completed under the Facilities Engineering Applications program, USACERL retrofitted 17 of the standard control systems at three Army installations to determine if they would correctly control the HVAC systems, reduce energy consumption, and reduce maintenance requirements. The study showed that retrofitted standard analog-electronic control panels would correctly control the HVAC system and would require little maintenance. The data collection results enabled researchers to estimate overall HVAC system energy consumption, but unexpected problems with the HVAC equipment coupled with the complexity of data collection and analysis, prevented the ability to make any claims about energy savings. The evolution of the analog-electronic Standard Control Systems into the single loop digital controller-based Standard Control Systems eliminated the emphasis to complete the analysis of the analog electronic Standard Control Panel performance. The study did show that a good control system would not compensate for design flaws or defective components of an HVAC system. Keywords: Retrofitting, Energy control systems, Energy consumption. (rh)
