Electrical Current Generation by the Flow of Refrigerants

Charge generation rates have been measured for two halocarbons and their mixtures, having electrical conductivities ranging from 7.5 ×10¿12 to 2 ×10¿15 ¿¿1 ·cm¿1. These fluids were passed through a 1.55-mm diameter tube as a liquid and as a mist at high velocity at ambient temperatures. Due to the high vapor pressures of the materials, a closed system capable of operating at pressures up to 30 atmospheres was utilized.
