Influence of the Dry Cooler Capacity on the Efficiency of Chillers

The EcoDesign Directive has set high efficiency standards and we are all under a legislative and a moral duty to ensure chiller systems are fit for purpose and as energy efficient as possible. While EcoDesign has forced Chiller technology to improve significantly over the years, energy savings can be further enhanced by the addition of dry coolers.
However, a recent drop in dry cooler sales, shows that many new chiller installations are missing out on important energy and financial savings. Chiller systems have to hit Minimum Energy Performance Standards (MEPS) and have separate performance requirements depending on chiller type and application. Ensuring systems go above and beyond MEPS brings lower running costs, less environmental impact, and possible future proofing against further legislation. To allow for energy efficient system design, manufacturers have to provide EcoDesign data by law. However, not all data is equal and for the professional, navigating between certified and un-certified products can be a minefield.
Eurovent Certita Certification (ECC) was asked by the ECC certified heat exchanger manufacturers, to independently test the performance of nine heat exchangers. These were manufactured by seven European companies, not participating in the Eurovent certification programme. The objective of this presentation is to share and explain the results of these tests to understand the impact of dry coopler capacity on chillers efficiency.
