LU-VE’s New Combined Spray and Adiabatic System for CO2 Gas Coolers
2017/09/22
Emeritus is the latest innovation developed for the range of condensers, dry coolers, and CO2 gas coolers manufactured by LU-VE Exchangers. This new technological advance (patent pending) is the result of collaboration with Polytechnic University of Milan and brings together the benefits of spray systems and adiabatic precooling. A sophisticated control system maximizes the effects of these combined systems.
 
Emeritus is particularly suitable for air-conditioning and refrigeration applications: when applied to CO gas coolers, high system Coefficient of Performances (COPs) can be reached even during the hottest periods of the year. This means that the ‘CO2 equator’ can be redrawn, extending the geographical area in which trans-critical systems can be cost-effectively constructed. The technology with an adiabatic system alone shows clearly superior performance. A reduction of 10 K in the CO2 outlet gas temperature has a positive consequent impact on the COP of the system. LU-VE made a comparison under equal conditions (the same capacity, the same evaporation temperature, etc.), and a COP increase of 69% was obtained (hypothesis of a simple cycle with an evaporation temperature of -8°C: the COP rises from 1.31 to 2.21).
