1. Conversion from HCFC-22 to HC-290 in Residential Air-Conditioners Update on China and India Experiences Joint Meeting of the Regional Ozone Networks for Europe & Central Asia (ECA) and South Asia (SA) Istanbul, Turkey, 26-30 April 2010 Markus Wypior, GTZ-Proklima 03.05.10 PROKLIMA

3. Types of room air-conditioning equipment

4. Historical and forecast production of RAC equipment in China (for domestic consumption) Increase is nearly exponential !

6. Success of Greenfreeze Technology-Diffusion Worldwide Now, even in USA, introduction of HCs in some domestics and trials in ice cream freezers and bottle coolers
