Thermal Efficiency Characteristics Of Indirect Evaporative Cooling Systems, Ben Costelloe, Donal Finn May 2005

Thermal Efficiency Characteristics Of Indirect Evaporative Cooling Systems, Ben Costelloe, Donal Finn

Conference Papers

Recent developments in enhancing heat transfer in cooling towers, together with the success of chilled ceilings, have prompted a review of the evaporative cooling technique. in temperate maritime climates. The thermal efficiency of such systems is a key parameter, as a measure of the degree to which the system has succeeded in exploiting the cooling potential of the ambient air. This paper presents the results of experimental research into the thermal efficiency of a water-side open indirect evaporative cooling test rig designed to achieve low (1-4 K) approach conditions. Secondary efficiencies in the range 0.24-0.76 have been achieved.

Mechanical Damping System For Structures, Jay A. Puckett, Patrick S. Mcmanus, Homer R. Hamilton Iii Jan 2005

Mechanical Damping System For Structures, Jay A. Puckett, Patrick S. Mcmanus, Homer R. Hamilton Iii

Durham School of Architectural Engineering and Construction: Faculty Publications

A mechanical damping system for a structure is provided. The mechanical damping system comprises a tubular impact frame secured to the structure. A support frame is secured to the structure with the support frame spaced from the impact frame. An elongated member is provided having a first end and a second end. The first end is secured within the support frame and the second end is free from connection and extends into the impact frame. At least one impact mass is secured to the second end of the elongated member, the impact mass movable within and contactable with the impact …


Research Into Evaporative Cooling Of Buildings In Maritime Climates, Ben Costelloe, Donal Finn Sep 2002

Research Into Evaporative Cooling Of Buildings In Maritime Climates, Ben Costelloe, Donal Finn

Reports

Concern with environmental emissions has focused attention on traditional forms of energy use in buildings, with a view to reducing and making more rational use of energy consumption. One area of concern is the traditional, refrigeration based, commercial air conditioning system, which has high levels of electrical power consumption in fans and refrigeration compressors. There is also concern among building owners and design teams, supported by the PROBE series of post occupancy studies, conducted by the CIBSE, that many buildings, with traditional forms of air conditioning, under perform in terms of occupant satisfaction, ease of operation and control, maintenance costs …


Evaporative Cooling Availability In Water Based Sensible Cooling Systems, Ben Costelloe, Donal Finn Sep 2001

Evaporative Cooling Availability In Water Based Sensible Cooling Systems, Ben Costelloe, Donal Finn

Conference Papers

Recent developments have prompted a review of evaporative cooling technology as an effective means of cooling modern deep plan buildings. Prominent among these developments is the success of high temperature sensible cooling systems, such as chilled ceilings, which require a supply of cooling water at 14 to 18°C. Crucial to the success of evaporative cooling technology, as a significant means of cooling in modern applications, is the ability to generate cooling water, in an indirect circuit, at a temperature which closely approaches the ambient adiabatic saturation temperature or wet bulb temperature. Recent research in this area has shown that it …


Motorized Insulated Damper Assembly For Furnace Systems, William Max Kirk, Timothy Wentz Apr 2001

Motorized Insulated Damper Assembly For Furnace Systems, William Max Kirk, Timothy Wentz

Durham School of Architectural Engineering and Construction: Faculty Publications

A damper unit is provided that is adapted to be positioned in a furnace duct line. The damper unit has a housing which is in communication with a fresh air source and a furnace system. The housing has a damper blade which is moveable between an open position which allows air flow through the housing and a closed position which prevents air flow through the housing. The blade is coupled with a Solenoid so that when the Solenoid is activated the blade is moved to an open position allowing air flow through the housing. Further, a fan is located in …


Cultural Resources Overview And Management Plan For Big Flat, Del Norte County, California, Susie Van Kirk Jun 1994

Cultural Resources Overview And Management Plan For Big Flat, Del Norte County, California, Susie Van Kirk

Susie Van Kirk Papers

This report presents the findings of a prehistoric and historic cultural resources records search and the resulting cultural resources managements recommendation for the Big Flat Planning Unit located in Del Norte County, California. This study was requested by Ernie Perry, Director of the Del Norte County Planning Department. The results of this study together with are intended to be incorporated into an Environmental Impact Report being prepared by Del Norte County Staff for the private lands which make up the Big Flat Planning Unit. The Environmental Impact Report is being prepared to assess possible impacts to the study area which …

Dickey-Lincoln School Lakes Project Environmental Impact Statement: Appendix J: Coordination With Other Agencies & Public Involvement (Supplement), New England Division, United States Army Corps Of Engineers

Dickey-Lincoln School Lakes Project

This agency will be particularly concerned about any impact which this project might have on any existing, proposed or known units of the National Park System, or any known historic, natural or environmental education sites which are currently part of , or eligible for, the National Landmark Program. This report is a planning aid for the proposed Dickey-Lincoln Dams and Reservoirs project in Maine. A number of endangered, rare, or unique animal species are known or suspected to occur in the project area.


Dickey-Lincoln School Lakes Project Transmission Studies Environmental Impact Statement: Appendix B: Alternative Power Transmission Corridors, United States Department Of Energy, United States Department Of The Interior Jan 1978

Dickey-Lincoln School Lakes Project Transmission Studies Environmental Impact Statement: Appendix B: Alternative Power Transmission Corridors, United States Department Of Energy, United States Department Of The Interior

Dickey-Lincoln School Lakes Project

This report identifies alternative corridors of land within which transmission lines could be routed and details various impacts on the environment which would be associated with introduction of transmission facilities. Many alternative corridor locations were identified (see Figure 1-1). Identification of these alternative transmission corridors was a complex process, since the number of potential corridors capable of connecting the various substations was myriad; the 'least desirable' potential corridors, i.e., those where transmission facilities might have entailed severest impacts on the environment, had to be eliminated from consideration before alternative corridors could be delineated. Identified alternative corridor locations were subsequently evaluated …
