Chillers provide high performance in a compact size
July 1, 2015
Mitsubishi Heavy Industries Ltd. (MHI) has developed a new series of centrifugal chillers, called the ETI-Z Series, that use a new low-global warming potential (low-GWP) refrigerant, HFO-1233zd(E). The various models in the new series will be progressively launched starting this September.
Energy savings and enhanced thermal comfort for occupants will drive sales
June 29, 2015
The market will be driven by an increase in demand for energy saving in buildings and enhanced thermal comfort for occupants, in addition to the increasing benefits of chilled beam systems, such as low noise levels, floor-to-floor space savings, and good IAQ in various applications.
A well-maintained unit will continue to function at the original optimum efficiency

These simple preventive cooling tower maintenance tips can help users save up to 15 percent on electricity costs. Routine maintenance also helps to conserve water and extend the operating life of cooling equipment.
The chillers increase energy efficiency and reduce environmental impact

Trane, a brand of Ingersoll Rand, has introduced the Trane® Sintesis™ family of air-cooled chillers, which are engineered to use the low-global warming potential (GWP) refrigerant R-513A. The chillers are now available for order in North America, Latin America, Europe, and the Middle East.
The Carrier ChillerVu plant control system is able to control Carrier 19, 23, or 30 series chillers (air- or water-cooled) and includes full integration capabilities, allowing it to monitor and control other equipment in the chiller plant, including non-Carrier chillers.
Even as the economy has improved, some building owners and operators remain hesitant to make large capital expenditures to replace older chiller systems. In these cases, there are less expensive options available that can enable decision makers to achieve substantial efficiency upgrades by retrofitting their chillers.
When it comes to large commercial systems, cooling towers seem to receive less attention than other system components. Yet, cooling tower maintenance is vital to ensuring overall system efficiency and preventing downtime.
Some in the industry have described ASHRAE Standard 90.1 as a complex standard, yet chiller experts say the shift in the standard to a more holistic view of chiller efficiency is the right direction for the industry.
