shrinking the size of the traction drive and its associated high heat flux electronics while maintaining net power output [5]. A previous paper [6] details the development process for the floating loop. Figure 1 shows schematically the layout of ORNL's floating loop. An adjoining loop shares the condenser with the existing automotive AC.High-pressure liquid exits the condenser and enters the loop. The use of the hotter refrigerant is possible because the temperature demands of the electronics are not as strenuous as that of the passenger compartment.The subcooled refrigerant is pumped through the loop and reenters the condenser after the automotive AC the loop and reenters the condenser after the automotive AC refrigerant contains some liquid and is not entirely vapor. In this test configuration, a resistive heat load was used to simulate the waste heat of a motor and its associated electronics.
