Hybrid vehicles have special needs when it comes to heating, ventilation and air conditioning (HVAC) operation. Refrigerant charging should be performed away from open flames or high energy ignition sources. Consequently, a large amount of kinetic energy is converted into vortices and is wasted. Let's be clear: There's no such thing as a truly air-powered car. But, since it still has some pressure, the compressor doesn’t have to work quite as hard.Ejector cycle. Depending on the quantity released in air, the material can travel a considerable distance to a low-lying ignition point. It next flows through an expansion valve, but this expansion valve doesn’t make the refrigerant vaporize. Carbon dioxide was considered. The Prius ejector A/C system has two evaporators stacked together so that they would fit inside the blower assembly box behind the dash.
