Power Saving Technology of Scroll Compressor for Car Air Conditioner

摘要

Car air-conditioner compressor input power must be reduced to protect against global warming. Input power was reduced by developing a highly efficient scroll compressor and implementing outer demand capacity control. The highly efficient scroll compressor was achieved by developing a high-strength scroll center profile that reduces recompression loss. This effect was verified by compression chamber pressure measurement. Suction pressure is controlled optionally by a new demand capacity control valve that controls air temperature discharge directly, without reheating the heater core - greatly reducing overall compressor inpur power.
