Use of Plant Toom Logbook Data to Establish Performance of a Cooling Production System
MetadataShow full item record
In medium and large size air-conditioning (A/C) systems maintaining a logbook that has hourly data on operation of chillers and pumps is mandatory. The paper presents a methodology for establishing performance of a chilled water A/C system and applies the same for an office building in Kuwait. Data collected between March and October 2004 were analyzed. Inadequate control of supply water temperature and low chiller loading were identified as the key parameters leading to inefficiency of cooling production. This simple and low cost approach can be extremely valuable for medium size plants in capacity range of 100-250 RT, which are often without any other mechanism for performance data gathering such as plant room manager or building automation system.
