A high performance innovative HFC-134a chiller, having recently received a UK Cooling Industry Award, has brought significant energy savings to its users.
After their adoption by the EU Ecolabel National Competent Bodies, in June 2011, Ecodesign requirements for domestic air conditioning appliances of up to 12 kilowatts have been published on March 10 in the Official Journal.
Abbotsford Regional Hospital and Cancer Centre (Vancouver, British Columbia, Canada) has received a first place award for the design of its HFC-based cooling system, featuring two 3,200 kW high-performance centrifugal chillers.
The Polish subsidiaries of one of the World’s largest Supermarkets chain have installed new commercial refrigeration systems using the HFC blend R-407F (containing HFC-32, HFC-125 and HFC-134a) in 75 stores, from which 60 are newly installed and 15 having been converted from R-404A (containing HFC-125, HFC-143a and HFC-134a).
HFO-1234ze, for which the US EPA has accepted a GWP of only 6, is being used as a propellant for non flammable technical aerosols.
A British supermarket chain, previously committed to hydrocarbons refrigerants, has decided to test an HFO-1234ze chiller in one of its stores.
Most accidents are due to equipment failures or human errors. These factors reinforce the fact that for each refrigerant use, and particularly those with dangerous properties, accidents must be minimized by high technical standards, good maintenance of installations and adequate training.
According to a new Report from French research institutes ARMINES/ERIE, commissioned by EPEE, Greenhouse Gases (GHG) emissions from refrigeration, air-conditioning and heat pump equipment have decreased since 1990 and are set to decrease even further in the coming 20 years.
While dismantling an old refrigeration system in a brewery near Brussels, three workers from an outside firm cut a pipe still containing ammonia under pressure. They were surprised by the sudden release of ammonia from a pipe that was supposed to be empty.
