Yukio Yamaguchi - Efficient CO2 refrigeration system
PDF document
published on 3 February 2014
This presentation analysed a CO2 cascade system installed in a small supermarket with a cooling capacity of 6.0kW, including its initial test results and actual performance efficiency ratings. Yukio Yamaguchi, General Manager of the Development Department of CO2 Refrigeration within SANDEN, highlighted CO2 as the working fluid that provides the ultimate commercial & environmental solution. He stated that the implementation of governmental incentives for POS are required to assist the wide-spread uptake of CO2 on the market. This presentation also showcased SANDEN's signature heat pump technology and vending machines.

Sadao Nishimura - Ultra Eco-Ice system - innovative solution for Japanese supermarkets
PDF document
published on 3 February 2014
Sadao Nishimura from Yamato presented the company's innovative Ultra-Eco-Ice System, which uses cold energy accumulated during nighttime for refrigeration and air-conditioning inside the store and display cases. At night, thermal storage refrigerators produce low-temperature brine ice, which is accumulated in a thermal storage tank. This allows supermarkets to better deal with peak demand during the day. In the winter, the system is able to recycle the condensing heat recovered from the refrigerators in-store floor heating. The Ultra Eco-Ice System is already used in 13 facilities.

Katsuhiko Harada - Development of CO2 cooling system for supermarket
PDF document
published on 3 February 2014
In this presentation, Katsuhiko Harada, the President of Nihon Netsugen Systems, described a CO2 cooling system in development for medium and large size supermarkets. Partnering with German compressor manufacturer GEA Refrigeration Technologies, Nihon's prototype unit includes GEA Bock's CO2 semi-hermetic reciprocating compressors. The prototype unit is a booster system consisting of transcritical and subcritical compressors. One unit can cool down both medium temperature and low temperature domestic cabinets whilst creating hot water by way of a heat recovery function. The first supermarket installation is planned for 2014.

Michael Englebright - Solutions for small footprint CO2 installations
PDF document
published on 3 February 2014
CO2 technology is becoming a mainstream solution for medium to large installations; however, the uptake of CO2 solutions in small installations still faces some barriers, such as investment cost, usability for installers and system complexity. Michael Englebright, Global Key Accounts Manager for Retail at CAREL, showed how these barriers can be addressed and overcome and highlighted the advantages of using a CO2 transcritical booster system.

Oliver Javerschek - Evaluation of CO2 booster system in Asian climate conditions
PDF document
published on 3 February 2014
Oliver Javerschek, Project Manager at Bitzer, presented real data about an experimental and empirical study of a second generation CO2 booster system in an Asian climate. He provided a comparison of an optimised R404A / R404A system, an optimised hybrid system R134a / CO2 cascade and a CO2 booster system. In the chosen Asian climate, the optimised hybrid system with R134a and CO2 showed the best annual efficiencies; however, applying a 3rd generation CO2 booster system could shift the results in favor of the CO2 booster system.

Bill Ho - Plug-in hydrocarbon showcases - case studies from Japan and South East Asia
PDF document
published on 3 February 2014
AHT Cooling Systems produces a range of R290 cabinets. In his presentation, Bill Ho, Sales Director for AHT Cooling Systems Asia Limited explained that his company has supplied more than 530,000 of these cabinets all over the world. The R290 cabinets are not only environmentally friendly; they are also very low on energy consumption and low on capital costs. They provide significant energy savings compared to remote systems and offer up to a 60% reduction in running costs compared to open top freezers. Design benefits include a large volume capacity, high visibility due to the curved lids and lowered front edges, as well as flexibility within the store (plug-in solution).
