[-] text [+]

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.

Euroklimat | R290 fluid chillers providing air conditioning for a cash & carry warehouse in Padua, Italy by Giulia Fava

Euroklimat offers a wide range of propane chillers for a variety of applications. The presentation will provide an opportunity to view an installation in Italy at one of the premier Cash & Carry chains, which has opted for a natural refrigerants solution to meet the demand for air conditioning throughout the building.

The cooling capacity of 500 kW is provided by two R290 air cooled fluid chillers. This case history demonstrates how, even for such a high cooling requirement, propane is a practical alternative to high GWP refrigerants. With more than 350 installations across Europe, Euroklimat’s team of technicians has over a decade of experience in design and construction of R290 fluid chillers and they are always available to share their expertise.
Huayi Compressor Barcelona | R290 compressor range for small light commercial applications by Vicente Guilabert Hernandez
Huayi Compressor Barcelona , S.L. has a long consolidated history designing, manufacturing and selling compressors for the light commercial refrigeration market using hydrocarbons as refrigerant gas. In 2016, Huayi Compressors Barcelona, S.L. has launched the smaller B and L ranges starting from 2.2 cc and able to work with R290 in LBP and HMBP applications.

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

International awareness with regard to the handling of environmentally harmful substances has been increasing in recent years.  Due to legal requirements resulting from this, applied technologies in the field of HVAC&R have increasingly been substituted by applications with natural refrigerants. Considering the mandatory continuous reduction of emissions that are harmful to the environment, this development will probably continue in the following years.
As a technology change across the market has already been taking place for a number of years, it makes sense to compare the energy efficiency of existing plants that run on traditional refrigerants with that of new plants that use natural refrigerants. Against this background, we will compare various R134a plants with several R744 plants with regard to their energy efficiency, fault statistics and plant performance, all based on measurements. The use of different plant concepts and technologies, e.g. heat recovery, ejectors and parallel compression, will be considered.
