I recently visited a friends project involving restoration of the oldest theater in Texas built in 1912. This theater is in the beginning stage of reatoration and has no working hvac equipment. It was cooled starting in the late 40s by evaporative coolers which work some of the time in Central Texas but not so much when the humidity is high. The coolers are in bad condition and we do not plan to reuse them. Heat was provided by 2 hanging gas fired fan forced heaters in the front of the auditorium. These will not be reused either. They do not provide any heat for the lobby, restrooms, or box office. There is a very strange control panel for the evaporative coolers with a guage, a container with some kind of chemical and the on off switches for each of the blowers. I wish someone could tell me what the guage and the jar of chemical would be for. I am not old enough to know what it is. there is a 1/4' tube running from the guage to each cooler cabinet. I can post pictures if anyone can help. I will be contacting a good friend I previously worked with to help with this project but I am open to suggestions on the job.
The theater is 50' wide, 100' long including the lobby area and the ceiling is
20' high. The walls are brick outside and plaster inside. The floor will be concrete when finished, wood now. The roof is metal squares about 2X2 and are original 1912 vintage. The roof is shingle over wood pitched in the center so there is an attic running fromt to back with room for ductwork in the center. The seating capacity after completion will be aprox 250 persons. When completed the attic will be insulated which is is not now.
I really want to know what the old controls are for. I do not know how to post pircures on here. Jim in Waco, TX email@example.com.
