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.

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 …
