Abstract : A recently completed construction is an apparatus to measure steady-state and periodic heat flow through 8-ft square wall sections. The apparatus consists of two 8- by 8- by 4-ft boxes open on one side, between which the test wall is placed. One box is maintained at the desired constant cold side temperature from -35F to +50F for steady-state tests or varied according to some predetermined cycle for periodic heat flow tests. The other box is electrically heated to maintain a constant warm side temperature of from 65F to 75F. The heat transmission coefficient for the wall specimen is calculated from the measured electrical input and temperatures. (Author)
