PM-1 AIR-COOLED CONDENSER TEST PERFORMED AT THE CLIMATIC LABORATORY, EGLIN AFB, FLORIDA
Abstract
A single module of the PM-1 four-module condensing system was tested over an ambient temperature range of +70 to -65 degrees F. All modes of normal operation, transportation and handling, as well as some emergency conditions, were imposed on this condenser section. The unit was shown to have an adequate margin of safety in all of its design parameters. The calculated over-all heat transfer coefficient was exceeded by 5.3%. The air side pressure drop was 17.2 percent less than predicted. The total power requirement for the design heat load was, when extrapolated to 6500 ft elevation, 10% less than predicted. It was shown that the total PM-1 plant load can be carried by 3 sections (at sea level) at ambient temperatures below approximately 50 F. The entire condenser can operate well below its minimum flow requirement of 2400 lb/hr at all ambients and it was shown that the air cooler can cover the range of 400 to 750 lb/hr at all ambient temperatures. Modifications were made to the unit during the test to achieve the above performance. These modifications included the addition of flow guides and orifices to the air cooler tube inlets, the addition of air baffles to the main bank and air cooler tubes, a change in the location of the condensate outlet connection and a change to the air cooler water box division plate drain ports. The ability of the unit to be transported aboard a C130A Air Force cargo plane was demonstrated. (Author)
