Natural refrigerants as successors of R22
Things are beginning to heat up for the refrigeration and air-conditioning industries. At the end of 2009, the next stage of regulations in the government’s plan to phase out R22 becomes effective. The refrigerant, utilized in countless cold storage warehouses and refrigeration systems, is now only available as a recycled commodity. Since no new R22 (chlorodifluoromethane) may be sold, there might soon be a bottleneck, which synthetic replacements can only bridge for a short while. Also, the climate-damaging hydrofluorocarbons are being threatened with a ban. The funding program of the German government therefore makes the radical conversion to natural refrigerants a feasible alternative.
