New air conds

After the central air cond failed some time back, the pressure on the window units found at the general heavy equiptment lab increased. The frequent breakdowns of the air conds caused many in the lab to break sweat. Thus, the department had no choice but to fix the air conds. So the day came when workers lined up outside the yellow doors:


Workers in the general equiptment area. They had to open up the false ceiling, take out the old air cond ducts, put in new air cond ducts, made a mess of the whole place.


The old air cond ducts. Someone should culture some of that stuff on petri dishes. Could open a zoo I think...


The new Mr.Slim Mitsubishi units. I guess its a 2.5 horsepower. There were 4 units installed. Supposedly they are going to close the doors that lead from the main lab corridor to this general lab area. So the corridor will still be hot while the general lab will be freezing antarctica.
