AmericanStandard air chillers/heaters

Good point. I hadn't thought of that. I have a vague memory of using 20W-50 in the summer and 5W-20(30?) in the winter. This was back in the 80's, though, so I might be thinking of a different car with the oil types.

The next time a friend comes over I'll ask him to open and close the doors to see if I can air movement at the vents.

Thanks,

Jim

Those vents in your pictures are the original ventilation systems for your building. There was a blower system attached to all the vents on the top of the building. These were all hooked together, usually in a row from top to bottom and sometimes connected to another row. Some blowers were on timers to run for a few hours in the morning and evening. Others were on all the time. This was before the time when most units now have individual exhaust fans. Some buildings still use this type of system for air removal and exchange. Others have taken these and added exhaust fans into the individual living spaces and vent the exhaust through them.

Warm, have you checked out the chiller and/or cooling tower? You might be able to get a tour.

Chiller Plant

Here is a link showing a very large chiller plant in operation along with all of the associated equipment, pumps, etc. The apartment building would be quite similar but on a smaller scale.

The chiller-boiler room tour sort of like what was in a gov't building that I used to work in at Downtown Wash DC.A few times I had to start the Trane chiller system that cooled my area of the building I was in.I would go to unit#3-touch the enable button and several minutes later the shop was cooling down.It was amazing how fast the cooling would work!.The Trane chiller was 1200Ton capacity.don't know what other areas of the buiding it cooled.Sure that has been all changed now-the chiller area of that building would be automated and remote controlled.The building engineer at the time let me start the chiller.I also repaired an air compressor for him-was a quiet night in the studio maintenance shop-you wouldn't think air compressors would be under usual studio equipment.The engineer needed help in installing the intake air unloader valve relay.The compressor worked fine after the relay install.Before it wasn't unloading and tripping its breaker.We have a much smaller chiller/boiler room here at the transmitter plant-have to check it each night.two 150 tone carrier chillers and two Cleaver Brooks boilers-those only work in winter-and only when really needed.Transmitter heat helps.Sometimes have to reset the chillers if the control room temp climbs up when its really hot outside.
