Feasibility Study of Noise-Level Reductions for Computer Display Channel Equipment Using Underfloor Environment Air Cooling.
Abstract
A Rocky Mountain Region Employee Suggestion, No. 9-73-4-ZDV-AF, recommended the removal of equipment cooling fans and the use of existing room air-conditioning for a noise-level reduction and as the equipment cooling medium. The underfloor cooling air was directed into the cabinets through the area occupied by the fans. The removal of the fans would result in a noise-level reduction within the room. This report evaluates feasibility studies of noise-level reduction through recovery conducted at the Boston Air Route Traffic Control Center (ARTCC). Results showed that it is possible to reduce noise levels and, in most equipment critical electronic locations, provide a reduction in operating temperature as a result of the flow of the colder underfloor air through the Computer Display Channel (CDC) equipment.
