Narrative:

About 10 minutes after takeoff and about FL230; the cockpit filled with smoke accompanied by an acrid odor. I had just increased the temperature setting on all three temperature selectors. Both crew members immediately donned oxygen masks. I moved the temperature selectors back to the full cold setting. I took control of the aircraft and asked the first officer (first officer) to run the smoke; fire or fumes checklist. We asked for vectors. We immediately received vectors and a lower altitude from center. The QRH procedures were completed and the first officer constructed the ILS. We requested emergency vehicles. After about 2 minutes the smoke dissipated and the landing was uneventful. AC pack malfunction caused smoke in the cockpit.
