This is the second of two articles on the Harvard Tunnel...
Weld Hall, one of nine operating stations in the Tunnel system, regulates the busy Main Yard area of Harvard. Next year, when an electronic data processing unit is put in the basement, Weld will become the control center of the entire system. The office of Mr. Floyd Kingsbury, foreman of the Tunnel engineers, is strategically located next to the room in which this "computer" will reside, and it was here that Mr. Kingsbury gave us a briefing on how Harvard is heated...
Steam from the Cambridge Electric Company's boilers enters the three pipes in the Tunnel at a pressure of one hundred pounds per square inch and a temperature of 425-430 degrees Fahrenheit. (Depending on the needs of the University, one or more of these pipes may be shut down.) After going through reducing valves which lower its pressure to about five pounds per square inch, the steam travels to individual buildings where it heats tanks of water. The Houses and most other buildings outside the Yard have their own water reservoirs, including separate tanks for domestic hot water...
...station. At all times, both in the Yard and outside, the steam remains within a closed network of pipes; but in the process of giving up heat much of it condenses to distilled water. This condensate is collected and pumped (through a small pipe on the floor of the Tunnel) back to the Western Avenue power plant where it is again converted to superheated vapor...
...data board makes it possible to find out what you want to know about a building without actually going inside. In the past, if a complaint came from, say, the Biological Laboratories that rooms were overheated, Buildings and Grounds had to dispatch a North Yard Tunnel man to the Biological Laboratories in order to get readings from the relevant thermometers and pressure guages. Now, whenever he wishes, a man sitting in front of the Langdell Hall data board can find out the air temperature of the Biological Laboratories (or a great many other things about any building in the North...
