Abstract
WITH the aid of cold-storage plant it is possible to regulate the supply of perishable foodstuffs to a city so that, whatever the season, the supply may be sufficient. A privately owned cold-storage build ing has been erected in Madrid with this end in view. O. Rhunke gives a description of the plant used in this building in the Escher-Wyss News of April. A five-storied building was constructed in the immediate vicinity of the principal markets, with the railway track on one side and the Calle de Toledo on the other. The level of the railway is 23 ft. above the level of the street, so that goods are unloaded from the railway into a chute and delivered into the street from the ground floor. Ten thousand cubic metres are provided for storage for eggs, fruit and fish. The main cooling is by conditioned air with brine-circulated cooling in addition. The temperature and humidity of all the cooling rooms have to be kept within prescribed limits. The used air is cleared out several times every day and ozonising is employed. Special care has to be taken to prevent any inter ruption of the cooling process taking place. A cooling capacity of thirteen million British thermal units per day is required. It was at first thought that such a spacious building would considerably exceed the needs of the city, but three months after the opening practically all the space was utilised.
