Cooling Analyses for Protective Structures Located Above and Below Ground
The objective was to develop techniques for predicting and controlling the effective temperatures in protective structures located both above and below ground. Two techniques were developed for underground structures: (1) A trial and error solution and (2) A graphical solution developed for this report. To check their validity, a 2-week field test was performed in a 200-man shelter at the U. S. Naval Construction Battalion Center, Port Hueneme, California. A trial and error solution for underground shelters, published by the ASHRAE, was also checked. Results indicated that all three solutions were satisfactory. For above-ground shelters, the technique described in NCEL Technical Note N-734 was expanded to include more types of structures, and the method of solution was made more flexible. Early in the experimental work, the need for instruments to measure thermal properties of soils in situ was recognized. A probe to determine thermal conductivity of soil, and a contact device to determine the coefficient of heat penetration into soil. (Author)
