ATMOsphere Asia 2016 selects naturals case studies

By team, Jan 18, 2016, 12:18 3 minute reading

With our annual ATMOsphere event series kicking off less than a month from now, we’re putting the final touches to the programme of ATMOsphere Asia 2016. This year, participants arriving in Tokyo will enjoy an impressive two-day programme boasting a record number of speakers, including 10 different technology case studies covering both commercial and industrial refrigeration technology.

With ATMOsphere Asia returning to Tokyo, Japan for the third time, next month will see the conference take over the Shin-Maru Conference Square on 9-10 February. In what promises to be a thrilling few days, Tokyo will be the place for the Asian HVAC&R industry to discuss and influence the future development of the natural refrigerant sector.

The presentations will cover a range of different technologies with a focus on natural refrigerants used in a variety of applications. The following ammonia-based case studies will be presented over both days of the conference.

Ammonia heat pump optimization at high temperature water heating, Rolf Christensen, Alfa Laval

This case study presentation will showcase the possibility to increase efficiency for high temperature ammonia heat pumps where a relatively large temperature rise on the water side exists. By splitting the condenser into two sections, it is possible to lower the condensing temperature and consequently increase the COP of the system. It is also possible to reach outlet temperatures higher than the condensation temperature. Using the concept, one can also achieve outlet temperatures substantially higher than the condensation temperature, and still recover much more heat than only that available by means of desuperheating.

Ultra-low charge ammonia glycol chiller cutting down operating costs, Inderpal Saund, Danfoss

The case study will describe in detail a recently installed ultra-low charge glycol chiller operating with ammonia as refrigerant. The capacity of the chiller is 160kW at -2 SST; the total charge is 4.9kg of ammonia. This brings the specific refrigerant charge down to an unprecedented 30g/kW refrigeration capacity (compared to 2,000g/kW in some commercial applications). The case study will further detail the decision-making process of the end user (Sylvan Mushrooms Australia) and how the ultra-low charge ammonia glycol chiller reduces operating costs as well as minimising the environmental footprint.

Operating results of CO2/NH3 refrigeration system, Ryouhei Suzuki, Mitsubishi Heavy Industries

This case study will explain the product outline of C-LTS by showing the introduction of the system flow lineup and operating results onsite. In addition, the latest installed examples of the CO2 hot water heater (Q-ton) will be presented. 
Mitsubishi Heavy Industries is experienced in the freezing device and refrigerator manufacturing business, with the CO2/ammonia refrigeration (C-LTS) series launched in 2005.
