Sanyo Air Conditioners has developed a new approach to converting existing R22 air-conditioning systems to use R410A. The cost of such a conversion is reduced by about 30% by using existing refrigerant pipework. The Renewal system can be used with virtually all types of R22 systems from leading manufacturers. On most installations, existing wiring can also be used. Any flare connections are replaced to enable the system to accommodate the higher working pressures of R410A. There are also significant ongoing savings in energy costs.’
