As the cooling coils are located entirely outside of the storage room proper, the room itself can be filled with goods snug up to the false ceiling at the top and against air ducts on sides. The side ducts and false ceiling only occupy about two inches of space in their respective locations, so the space occupied by the air system is very small. Storage men will at once appreciate that a saving of even 5 per cent in space adds that much to the profits of the season's business, as it is as expensive to cool vacant space as it is to cool it when occupied by goods. As an objection to the forced circulation system, it has been urged that the expense of running fans continuously for handling the air was so large as to be a serious item of expense. With a well constructed apparatus and a large light weight fan wheel running at a slow speed, the air in a room containing 15,000 cubic feet, which will store about 5,000 cases of eggs, may be circulated with an expenditure of effort not exceeding one-half a horse power. The selection of a fan for propelling the air is of considerable moment when installing an air circulating system in a cold storage room. Fans also play an important part in handling air for ventilating, and the merits of the different kinds and forms of fans will be discussed under "ventilation." CHAPTER IV. VENTILATION. value of T N discussing" humidity and circulation, it has been ventilation. I. 1 explained how a large portion of the gases of decomposition and impurities of various kinds, which are incident to the presence of perishable products in cold storage, are carried by the moisture existing in the air, and that when this moisture is frozen on the cooling pipes, or absorbed by chemicals, the foul matter is largely rende...
