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.
The US Air-Conditioning, Heating, and Refrigeration Institute (AHRI) has published “AHRI 700-2012: Specification for Fluorocarbon Refrigerants”, which specifies acceptable levels of contaminants (purity requirements) for all fluorocarbon refrigerants : CFCs, HCFCs, HFCs, HFOs and refrigerant blends.
Two 125 kW Organic Rankine Cycle (ORC) generators using HFC-245fa as working fluid have been installed in an Italian manufacturing plant where they increase the output of a biomass boiler, which converts the wood waste generated at the factory into renewable energy to heat and power the facility.
The EU Commission’s Draft Proposal 643(2012) for the revision of the existing F-gas Regulation 842(2006) was made public on November 7, 2012.
A recent consultant study, carried out on behalf of EPEE, has investigated the potential costs and the reduced greenhouse gas emissions from an HFC consumption phase-down in the EU.
An ASHRAE technological achievement award was delivered to the “Montréal Biodôme”, Quebec new energy recovery and energy transfer system, based on HFC-134a heat pumps.
A R410A based hybrid rooftop air conditioner adapted to hot-dry climates by utilizing indirect evaporative cooling to increase cooling capacity has been certified to pass the rigorous Western Cooling Challenge performance requirements to reduce peak electrical demand by 40% compared with current US federal standards.
