Case studies from Advansor, Carrier, EPTA, Euroklimat, Huayi Compressor Barcelona, SCM Frigo and Wurm will be presented at ATMOsphere Europe 2017 in Berlin, Germany.

The ATMOsphere Review Panel is pleased to announce the third round of case study selections for ATMOsphere Europe 2017 on 25-27 September in Berlin.

Advansor, Carrier, EPTA, Euroklimat, Huayi Compressor Barcelona, SCM Frigo and Wurm will discuss their innovative natural refrigerant-based technologies at the conference. 

The presentations are:

Advansor A/S | Transcritical CO₂ challenges traditional NH₃/CO₂ cascade systems by Mark Kristensen

Transcritical CO₂ systems are not only adventurous for commercial refrigeration installations; same technology is now being applied in industrial projects. The tendency of considering only TC CO₂ as an alternative to chemical refrigerants in supermarkets and convenience stores is meanwhile old news, in the past year(s) TC CO₂ has been chosen as the better alternative to traditional NH₃/CO₂ cascade systems. Benefits which consultants and end users are getting aware; as a result more and more MW project tenders now specify TC CO₂, either as only solution or as alternative to NH₃/CO₂.

This case study explains the concept and configuration of a 3,5 MW TC CO₂ system installed in the Netherlands. The case study addresses issues including first costs, operating and service costs.

Carrier | Latest developments in multicompressor CDUs using CO₂ by Julien Pourriere & Guillaume Burvingt

One of the most exciting areas of development in CO₂ as a refrigerant is in the area of small condensing units. We will present the results of the latest developments of our pioneering CO₂Y product range with multicompressors.

EPTA | CO₂ FTE transcritical technology performance vs previous solutions in real store conditions by Francesco Mastrapasqua

Francesco Mastrapasqua will presents the new FTE system, advanced CO₂ transcritical solution applied in real store conditions. In particular the case study will present an in-depth analysis of the energy efficiency and operational benefits of the FTE system in presence of liquid and gas ejectors, parallel compression and mechanical subcooling.

Extensive data will be presented to reason for increased usage of CO₂ refrigeration systems in any climatic condition and any store format, combining costs, energy saving and reliability, a significant contribution to make CO₂ natural refrigerant the new technological standard everywhere.

The case of study will demonstrate the benefits of using the smallest R290 compressor in a very small can cooler as replacement of the previous R134a system. There are several associated benefits that will be shown in the case of study.

SCM Frigo | TC CO₂ unit in South Africa with parallel compression, vapor ejector and hot gas defrost system

The case study will be presented in the Industrial Refrigeration Panel. The case study explains the performance of a transcritical CO₂ unit installed in warm climate (south Africa) with parallel compression technology, vapor ejector and hot gas defrost system.

Wurm | Performance comparison of modern CO₂ installations in operation  by Dr. Lukas Patryarcha
