We are pleased to announce the third round of case studies from Dorin, embraco, EPTA and Frascold to be presented at ATMOsphere China 2018.

The ATMOsphere Review Panel is pleased to announce the second round of case study selections for ATMOsphere China 2018 taking place on 11-12 April in Beijing.

Dorin, embraco, EPTA and Frascold will discuss their innovative natural refrigerant-based technologies at the conference.

The presentations are:

Dorin | Transcritical CO2 in Chinese industrial applications by Giacomo Pisano

This presentation will showcase the technical challenges faced by Dorin in the design of industrially sized compressors using CO2 as a refrigerant.

Examples of successful implementation in industrial systems will be detailed, such as cold storage warehouses in China and ice-rink applications in relation to the forthcoming Winter Olympic Games in Beijing in 2022.

embraco | Variable speed R290 compressors in Chinese light commercial refrigeration by Andre Paz Rosa

This case study will highlight two new applications of embraco's variable speed R290 compressors in China. The first is in a Haier ice-cream freezer which is widely used in the Chinese market. The second details the compressor's use in vending machine and ice coffee machine in China. The case study will detail the compressor's ability to reach a high cooling capacity while also balancing efficiency in several applications.

EPTA | Warm climate efficiency improvements for transcritical CO2 systems by John Austin-Davies

This case study will detail the results of trials conducted on EPTA's Full Transcritical Efficiency concept. EPTA's FTE concept has been developed as an innovative solution for the operation of transcritical CO2 systems in warm climates. The case study will detail its comparison to alternative systems in a working supermarket. Additionally, a simulated analysis of the system if installed in a warm southern China area will be included.

Frascold | Comparison and analysis of two CO2 transcritical booster systems by Livio Calabrese

This presentation will analyse and compare the performance of two different solutions during CO2 transcritical operation based on a one-year analysis.

This analysis includes transcritical booster systems with and without parallel compression system, as well as with and without heat recovery for sanitary hot water production and space heating. It is based on a sample of temperature ranges in Milan, Italy and will be compared to temperature conditions in Beijing, Shanghai and Guangzhou, showing COP results of up to 3.75.
