Proposed as a substitute for R404A (GWP of 3922) because of its lower GWP of 1300, a new HFO refrigerant blend has achieved a better refrigeration performance than R404A in a thoroughly tested commercial display unit.
Two 2,500 kW HFC-134a specially designed for “mission critical facilities” (note) Chillers systems have been added to two existing systems in a renovated large US Data Center serving its region customers.
Academic research has concluded that air conditioning is the central determinant in the reduction of the mortality risk associated with high temperatures that took place during the 20th century in the United States.
A new refrigerant leak detection system has been developed, achieving a much higher accuracy than the current detection methods through combining the use of a hydrogen-nitrogen mixture and of a hydrogen electronic detector.
At the last Montreal Protocol Meeting, IPAC published a Position Paper addressing among others future amendments to the Protocol, recommending that any amendment to control HFCs should provide unambiguous and self-implementing protections for medical uses of HFCs.
Two 4,750 kW highly efficient HFC-134a based large-size centrifugal chillers have been added to two already installed 1,250 kW chillers, to supply district cooling to the "Tokyo Sky Tree District", a 10.2-hectare area project centered on the 634-meter "Tokyo Sky Tree" tower.
