Designing a Dedicated Modern Wine Cooling System

Chiller & Cooling Best Practices, Mar. 2017, by Kevin Trowhill.
http://www.coolingbestpractices.com/industries/beverage/designing-dedicated-modern-wine-cooling-systems

"The temperature of wine must be kept stable throughout its production and storage in order to ensure final product quality that is acceptable for distribution and sale, and so cooling systems are an integral component of wine production. In wineries, the entire harvest can be destroyed by a temperature fluctuation during processing or storage, leading to catastrophic consequences for wineries. Cooling systems must meet three main criteria in order to be effective in wine production and storage applications: the cooling systems must be able to achieve the ideal temperatures for wine production processes; they must deliver consistent, reliable operation; and they must be well-designed for safe, convenient use."

Refrigerants in Transition: Impacts on HVAC-System Design

HPAC Engineering, Dec. 2016, by Ryan Geister.

"With the world’s attention increasingly focused on climate change, organizations are more attuned to carbon-footprint implications during the building-design process and the impacts buildings have on the environment. HVAC-system efficiency plays a crucial role in a building’s environmental impact. While it is important to choose equipment that delivers high-efficiency performance, it is even more critical to consider a building’s entire HVAC system during design."

Supermarkets: A Bellwether of Industry Changes

Air Conditioning, Heating & Refrigeration News, Sep. 7, 2015, by Ron Rajecki.
http://www.achrnews.com/articles/130513-supermarkets-a-bellwether-of-industry-changes

"Supermarkets and their needs will always be one of the front-and-center elements of the HVACR industry. These high-profile businesses operate long hours, use large amounts of energy, and have tens of thousands of dollars in perishable product that needs refrigeration 24/7. Trends in supermarkets can often provide insights into changes to come for the rest of the commercial refrigeration world, and — as is the case industry-wide — refrigerants are on the minds of many in the supermarket sector."

Post-HFC-Phaseout Refrigerant Options

Air Conditioning, Heating & Refrigeration News, Aug. 3, 2015, by Ron Rajecki.
http://www.achrnews.com/articles/130217-post-hfc-phaseout-refrigerant-options

"The July 2 ruling from the U.S. Environmental Protection Agency (EPA) that sets forth the timeframes for the phaseout of certain hydrofluorocarbons (HFCs) in specific applications presents some challenges for the refrigeration industry. The ruling also presents new opportunities for growth of the natural refrigerants market. The ruling, however, was not unexpected, and it did not catch many of the major refrigerant manufacturers flatfooted."

Safety and Energy-Saving Resulting from Early Detection and Prevention of Leakage of Low-Flammable Refrigerants

IEA Heat Pump Centre Newsletter, #33 2015, by Masahide Sumi. [Open PDF then scroll or jump to page 22.
http://etkhpcorder.extweb.sp.se/ViewDocument.aspx?RapportId=1267

"Leakage of refrigerants represents a high cost in terms of the energy required in refrigeration and air conditioning devices. As it is expected that low-flammable refrigerants will be used in many devices in the future, this issue can be very important for the global environment, energy saving and safety. The following article describes detection systems which can easily detect and identify leakage at an early stage, and a method which can easily prevent leakage from plumbing and joints of air conditioning equipment."
