You can see the shelter air system air conditioning unit to the right in the picture. There were originally 2 electrical generators in this room. The generators were located in front of the unit in the center of the picture. I believe the unit in the center of the photo is an air conditioning unit for the mechanical room itself. It has an air outlet at the top and air filters in it but isn't connected to the shelter air system by any ducting. The generators would have contributed quite a bit of heat to the room so it makes sense to me that the room would have had to have an air conditioner. The silver round air supply ducts for the generators can be seen to the left of the unit in the center of the photo. These ducts lead back into an air duct which draws it's air from the air filter chamber. The entry to the air filter chamber is in the far wall behind the center unit. The grating in the far corner, visible between the air conditioners, is the cover for the well pit. The air filtering system is actually part of the mechanical/ventilation system of the shelter but I decided to give it a separate page due to it's somewhat complicated layout. These photos were taken during the March 2003 tour. In the above left photo you can see the generator mufflers at the top center and top right under the large air duct in the photo. You can see the generator power leads hanging from their conduits just past the air duct. I found out during the second tour that the generators were removed some time in the 1990s. The grey door to the right in the picture is one of the electrical panel doors. Another bit of new information I found out during the March 2003 tour is that the air conditioners cooled the air with well water instead of refrigerant. I assume that the generator cooling systems must have also used well water. I'm not sure how that worked because the well water would have to pumped through the air conditioners and then out somewhere. Not sure where the well water would have been pumped out to. Door Lift Hydraulic System (Above Right Photo) These are the hydraulic pumps and fluid tanks for the blast door lifting cylinders. This system still appeared to be in good condition at the time. Here's another somewhat pointless photo I took in 2003. It does show the layout of the mechanical room a little. The mechanical room air conditioner is on the right and the door hydraulic system can be seen against the far wall. Go to the Air Filter System Back to Mayor's Office Back to EOC Main
