Shape Energy Resources' CabinAir system is a thermal storage heating and air conditioning system that stores heat or cool energy in a phase change thermal fluid system. The CabinAir design, interconnected to the climate control system on a heavy duty vehicle, is charged from the engine coolant or air conditioning system. On an Electric or Hybrid Electric Vehicle, the CabinAir system is charged during the battery recharging time using an on-board refrigeration system or electric resistance heating element powered by the battery recharging source. Vehicle drivers can select whether to store heating or cooling energy and later retrieve it as needed for cab comfort conditioning. This product technology will reduce unwanted emissions, save fuel, and condition a vehicle's interior environment making it comfortable for driving or resting.
