Energy and cost efficiency of R290 and R600a in commercial, light commercial, and air conditioning applications, as well as how to deal with the U.S.’s 150 gram propane limit, are just some of the subjects addressed by the Technology Case Studies chosen for presentation at this year’s ATMOsphere America 2013, which will take place on 18 & 19 June.
Low energy consumption when using R290 as alternative to R404a in a light commercial refrigeration freezer by Vicente Guilabert Hernandez, HUAYI Compressor Barcelona, S.L.
Focusing on commercial refrigeration applications, the case study highlights the complete system energy savings achieved when using R290 as an alternative to R404a, combined with the use of high efficiency mechanical kits and electrical motors, in a light commercial freezer.
Innovative hydrocarbon solutions – applied on a bottle cooler by Alex Alvey, Tecumseh Products Company
Focusing on small bottle coolers, single-door merchandisers and small beer (keg) cooler appliances, the case study will present energy efficiency gains and improvements in pull-down time, achieved when replacing HFC refrigerant with HC refrigerant for several real life examples in the US.
How to manage 150 grams propane limit with big plug in appliances in US Market by Doug Smith & Zgliczynski Marek, Embraco North America
In 2011, the EPA SNAP positive conclusion opened up an opportunity in the U.S. household and light commercial refrigeration applications for the use of hydrocarbons. However, the approved charge limit of 150g of propane creates a challenge for larger sized light commercial appliances. This case study presents different options for addressing this issue, including a comparative analysis.
Designing low charge R290 room air conditioners with smaller diameter copper tubes: examples from the US and China by John Hipchen, Exel Consulting
The case study demonstrates that when using smaller diameter, inner-grooved copper tubes in an R290 air conditioner, the refrigerant charge can be greatly decreased. Based on the 15 million units that have already been sold in China, the presentation will show examples of how this is, and can be, implement in North America. In addition, the presenters will give some insights on the development work that is being done in China with R290.
