New Vehicle Air-Conditioning System
KARIYA, Japan—Automotive technology supplier DENSO has developed a vehicle air-conditioning system that uses ejector technology. The company claims that the small refrigerant injector reduces the vehicle’s compressor power consumption by up to 25% compared to conventional car air-conditioning systems. The ejector replaces an expansion valve, and recovers expansion energy, which normally is lost in the expansion valve, and converts it into pressure energy, reducing the compressor’s workload. The system will be installed on the new Toyota Prius, scheduled to be introduced this month. – (via ASHRAE.org)
