hot

my lab has been at 25 degree for a week.
in order to raise the temperature, the air ventilation just kept blowing hot air out.
n so i bought a new tee last friday.
i guess the plant ops people finally realize that they should do sth w/ it.
n so today, the whole system is down!!!
the lab gets cooler... but... it generates a vacuum that we can't open the lab door!!!
