The second part of the experiment began with an activation of the evaporative cooled condenser. Water was pumped via a nozzle to the top of the cooling pad, saturated the pad, and excess water was re-circulated back to the water tank. The total time required to saturate the pad was approximately 5 min, and it took roughly10 min for the refrigeration system to reach steady state again. Due to evaporative losses, makeup water was periodically added to the water tank. The total quantity of makeup water was regarded as water was consumed by the DEC. This water consumption data was
