C - ban on new equipment except heat pumps and PAC D - ban on using any new equipment
Phaseout of HCFC in Hungary• According to Montreal Protocol and the International agreement• Hungarian Government regulation from 2003: – from 30 September 2003, (ban on) use new equipment HCFC – from 30 April 2004, (ban on) use reversible equipment (Heat pump)• Reduction new HCFC import step by step ! For on-going servicing needs of existing equipment: – in 2003-2004 696 t/y import – in 2004-2007 464 t/y import – in 2008-2009 387 t/y import• 31 December 2009, stop the import!!!• 1 January 2010, ban on production and import (new HCFC) except for use in equipment manufactured before 1/1/2010 (so no production or importing for NEW equipment that uses these compounds) !• 31 December 2014 final ban
Before and after 1-1-2010?• What should be done than?• For servicing of existing equipment!• New technology for servicing!• Reclaimed, recycled refrigerant?• Replacement (drop in or retrofit) with alternative refrigerant!
What about the solution!• According to the regulations (2037/2000) 1005/2009 and 842/2006• Training and certificationYour role: as an air-conditioning or refrigeration technician, you play an important role in the phase out procedure of HCFC refrigerants by installing, servicing, end repairing equipment that may contain HCFCs - better understand your responsibilities under the regulations. - adapt to changing industry practices, and - provide consumers with appropriate information about the HCFC phase out.
A) Servicing air-conditioning andrefrigeration systems• You must have a certification (personnel and company),• Do best practice, locate and repair leaks (leakage checks),• you must use refrigerant recovery equipment during service, maintenance, or repair,• you may recharge equipment only with recovered HCFC refrigerants,• recovered refrigerant cannot be sold to new owner,,• it must be recycled or sent to an certified reclaimer prior to resale.
B) Disposing of refrigerating and air-conditioning equipment,1. prior to equipment disposal, you must properly recover HCFCs from existing refrigeration and air-conditioning equipment to help ensure the availability of future supplies, protect the ozone layer, and comply with the regulations,2. you may recycle the recovered HCFC refrigerants,3. you may send recovered HCFC refrigerants to be reclaimed or destroyed.4. Disposal companies have to be special licences for transport and disposal procedures
C) Alternative refrigerants1. In generally HFCs,2. Certified personnel has to be informed about the acceptable and unacceptable substitutes for specific criteria of different refrigeration and air conditioning applications.3. Alternative refrigerants generally cannot be used as a "drop-in" replacement in an existing system without modifying the system components, sealings, etc
R-22&Co.• It is a popular refrigerant that is commonly used in a variety of refrigeration and air-conditioning equipment, including• Residential Commercial and Industrial Uses (-55- +15 oC)• How can we replace it, for example in: (LBP-MBP-HBP) - Window air-conditioning units - Packaged air-conditioners and heat pumps - Dehumidifiers - Chillers - Central air-conditioners - Retail food refrigeration - Air-to-air heat pumps - Cold storage warehouses - Ground-source heat pumps - Industrial process refrigeration - Ductless air-conditioners - Transport refrigeration -Chest or upright freezers

Practical advices• What to advise the customer? – Proof the task and conditions of the system, in generally: – If the refrigeration capacity of the system <300 kW, new system with new refrigerant, – If the refrigeration capacity of System > 300 kW, and fill in (R-22 T, reclaimed!) Replacement with - R-407C (HFC), - R-422A, - R- 422D
Real and actual situation- 31 December 2009, important datum- In 2010 R-22 refrigerant stock is about ≈ 700 t?.- For servicing R-22 (demand) ≈ 15- 25%, ≈ 105 -175 t/y.- Ban on new R-22 production. Reclaimed refrigerant isn’t enough. ≈ 40 t/y reclaimed refrigerant (all) 2010! more than 65-135 t/y absent, wanted !!! But the refrigerating system is running!
Tendency in refrigerant policy! What about HFCs?? Phase out?? Phase down? Depending Fgas regulation review,• ODP=0, reduction on GWP 1.) R-717 (NH3), R-744 (CO2), R- 290, R-600a….2.) Phase down HFCs : For MAC, GWP less than 150 (Aut. Air-cond.). Instead of R-134a GWPR-134a=1300: -HFO-1234yf (tetrafluoropropene) GWP=4 (mild flammability) -HFO-HFC (HFO-1234ze) blend (fluoro olefine) GWP=6 (testing) But proper use, containment and recovery, disposal, energy efficiency TEWI
The best combination to reduce energy consumption and face up to regulatory changesPolitical context – The objective of the EU : +20, -20, -20 until 2020:- Reduction in Greenhouse gas levels -20%- Reduce the energy consumption -20%- Renewables in energy mix +20%
