Low Temperature Air Distribution with Ice Storage System: A Case Study
This paper discusses the performance of an off peak ice storage air conditioning system installed on an office warehouse building in Dallas, Texas. The system also incorporates a low temperature (45 degree) air distribution system utilized with parallel fan-powered VAV boxes. The entire system is controlled by a microprocessor based Building Automation System (BAS) incorporating state-of-the-art direct digital controls (DDC). The economic performance of the system will be discussed by comparing utility bills, and the system performance will be observed through the use of actual trend logs taken from the BAS on a typical summer day. The reduced space relative humidity levels, resulting from the low temperature distribution system, will be ahown in actual trend logs also. The method of distributing low temp air without causing occupant discomfort (cold air dumping) will also be discussed.
