Heat Admitted into a Cold Storage Room by its Door-opening

Abstract

From his experimental results, H. S. W_HITESEL has given an empirical formula to estimate the heat load of the door-opening for a household refrigerator cabinet. To ascertain that his formula is equally applicable or not to a cold storage room of a larger size, we had made some experiments with a cold storage room, which has a preliminary chamber 168 ft³ and a cold storage chamber 216 ft³ in the internal volume respectively.
The results of our experiments have also shown that the values calculated from W_HITESEL'S formula are nearly equal to the measured values in the case, where the door-opening takes place between the open room air and the preliminary chamber; but for the case, where the door-opening takes place between the preliminary and the cold starage chambers, the volume of the latter being larger than that of the former, his formula must be modified.
