A 75MW system will have approx 50,000Kg R134a So leakage will be 500Kgs per year. This costs……….$20,000 per year in 2011....or more (Doubling every 2-3 years so by 2030 maybe $640k ?) And @ 1300 GWP = 650,000 kgs of Carbon =2.32 million miles in a VW Golf

Editor's Notes
- Heat Pumps See 'Logie Baird Star Envit.ppt' slides 9 and 10 Cooling of something involves the heating of something else (e.g. refrigerator extracts heat from inside and discharges this (plus compressor hear) as waste heat into the kitchen) Usually, that heat is 'lost' as waste from the process into the atmosphere Heat pumps either: Capture the heat from useful refrigeration, and run heating and cooling together Concentrate on the heat side of the process, and cool something that doesn't actually need to be cooled for any other reason, in order to generate heat e.g. ground, air, water If coupled to a “clean source of electricity, e.g. hydro or nuclear, or wind, or tidal, they multiply the heating capability of these resources by 3 fold. (Need 1/3 as many of the power stations!!) Heat pumps are environmentally 'friendly' and can generate heating and cooling extremely efficiently, and for that reason they are seeing widespread adoption

- Natural Refrigerant Here we see a timeline of refrigerant usage. Up unit the mid 1980s, the industry were happily using CFC refrigerant. However, with a link between ozone depletion and CFCs/HCFCs, the Montreal Protocol was signed in 1987 and resulted in the start of a 20 year phase out programme. CFC were banned from use in 2000 in the EU.

CFC were banned from use in 2000 in the EU.
- HCFCs, whilst having a lower ozone depletion were to follow. They were banned from new system in the EU in 2000 and a ban on the use of virgin R22 in existing systems can into place in January 2010. A total ban will start from January 2015 and until then, only recycled R22 can be used in existing plant. This has resulted in an increase in refrigerant cost, which is expected to continue to rise.
- Considerable time and money has been invested in finding replacement fluid for R22. His resulted in the new generation of HFC refrigerants. These have no harmful effect on the ozone layer but typically have global warming potentials 1000s of time greater than CO2. 1kg of R404A in the atmosphere is some 3400 time more potent than CO2. HFCs are also more searching refrigerants and have been shown to result in greater risk of leakage. If you are wanting to cut your carbon footprint, they aren’t the best solution. In recognition of this, the EU has put legislation in place to monitor and reduce refrigerant leakage. The F-Gas regulation puts greater emphasis on leak detection and can result in penalties for persistent offenders. This legislation is to be reviewed in 2011 and could result in tighter restrictions and could mean great taxation (as seen in Scandanavia). The future for HFCs is not certain and natural refrigerants are the way forward. Ammonia has excellent performance characteristics across a wide range of operating conditions and is ideal for heat pumps applicatiosn.
