Point-to-Point Verification of Monitored Sensors at Reynolds Army Clinic and Hospital Final Report

Abstract

A point-to-point verification of the heating, ventilating, and air conditioning (HVAC) system of the Reynolds Army Community Hospital (RACH) in Fort Sill, Oklahoma was done by the Energy Systems Laboratory (ESL) of Texas A&M University. Work began on January 12, 2004 and was completed on July 2, 2004. The facility consists of a clinic section having 212,000 sq.ft and a hospital section with 300,100 sq.ft. Both sections are contained in one building for a total of 512,000 sq.ft. The clinic section of the facility is occupied from 0700 hours – 1700 hours while the hospital side operates 24/7. Verification of the facility began shortly after the completion of a $2 million upgrade of the Energy Management Control System (EMCS) by Johnson Controls from their existing 8540 pneumatic system to a direct digital control (DDC) Metasys version 12.0 system. Only the points read by the control system and used for control sequencing were verified. In the following sections of this report detailed information will be provided for the type of equipment used for the point-to-point verification and calibration, calibration tolerances for the devices requiring calibration, areas that require attention prior to calibration, and calibration procedures. The remaining sections will focus on the central plant, clinic, and hospital areas. Each section will contain individual field data for each component tested and calibrated.
