Narrative:
Flight left on time. On climb out the flight deck was noticed to be rather chilly. Captain turned up temperature controller for PAC1. After some time the flight deck temperature and cabin temperature only got cooler; not warmer. Even with temperature controller in full hot and in manual mode; the temperature continued to drop. After talking with maintenance control; no solution was offered. Dispatch offered for us to descend. We requested lower from center; they assigned FL340. By this time the flight deck temperature was 8 degrees; cabin temperature 15 degrees. Since the captain and myself were freezing and shivering; we elected to divert to alb; 30 mi from our current location; and sort out the problem on the ground. Had the flight continued the temperatures would have continued to drop; compromising the safety of the flight.
