A recent report presenting the energy performance and environmental impact of recently installed refrigeration systems in a large retail chain showed that...
Following its approval by the US EPA, a large American appliances producer has decided to use HFO-1234ze (E) as a blowing agent for its refrigerators’ polyurethane insulation foam.
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.
Update F-Gas Regulation Review page :
R-410A geothermal heat pumps have been successfully tested for providing cooling to one of the an antennae of the ASKAP (Australian Square Kilometre Array Pathfinder), installed in extremely warm West Australia.
A meeting between UK DEFRA (Department for Environment) and members of the ACRIB F-Gas Implementation Group and other stakeholders (equipment manufacturers, installers, retailers, refrigerant suppliers, recyclers and the refrigerated transport sector) have had the opportunity to exchange views on the recent EU Commission’s Draft Proposal 643 (2012) for the revision of the existing F-Gas Regulation 842(2006).
Two HFC chillers, one of 1,750 kW and one of 900 kW, equipped with magnetic bearings, have been installed at the San Francisco Public Utilities Commission (SFPUC) headquarters in downtown San Francisco.
The UK Environment Agency had carried out a study to assess the flammability of refrigerator insulation foam blown with HCs (Hydrocarbons :cyclopentane, i-pentane, n-pentane or mixtures of these gases), and found that all tested foam samples should be considered "highly flammable", and, as such, should be classified as hazardous waste, unless tested and demonstrated otherwise.
Two HFC based 300 kW highly efficient chillers have been installed at the National Library of Scotland to replace ageing HCFC-22 chillers. The chillers are linked to a free cooling system, providing chilled water to a number of air handling units.
