ICE HOUSES AND 



In houses which are used for storage only a continuous 

 door should be provided to facilitate the filling and remov- 

 ing of the ice. The doors should be as well insulated as any 

 other part of the wall and should be provided with clamps, 

 which will enable one to close the doors absolutely tight, 

 thereby preventing any leakage of air. The doors are 

 usually beveled and closed against some material, as felt, 

 which makes a good seal. If loose insulating material is 

 used around the ice, a built-up door should be provided to 

 keep it away from the outside door. Where combined ice 

 house and cold store rooms are built great care should be 

 taken in the construction of the door to the cold storage 

 room, as this door is opened so frequently that losses will 

 occur, due to poorly designed doors. The door should open 

 and close easily and quickly from both sides, and when 

 closed it should prevent the leakage of air. A three-foot 

 door is large enough for all ordinary purposes. All win- 

 dows should be at least double and rigidly fastened in place. 



ICE HOUSE NEEDS VENTILATION 



All ice houses should be provided with some means of 

 ventilation, to aid in breaking up the heat radiation of the 

 roof and to carry off moisture. When the ice house is 

 opened the cold air will literally fall out and be replaced 

 with warm air, which, when the ice house is closed again, 

 will, unless given a chance to escape, use considerable re- 

 frigeration before it is cooled down to the temperature of 

 the ice. To reduce this loss a door is provided above the 

 ice, which is opened just after the day's supply of ice is re- 

 moved and should be tightly closed soon afterwards. 



When houses are exposed to the direct rays of the sun 

 it is well to provide some means of circulating air in the 

 walls to break up the heat radiation, as shown in Fig. 2. 



USE ODORLESS WOODS IN COLD STORAGE 



ROOMS 



The best wood to use in building cold storage rooms 

 will depend on the most available wood. It should be odor- 

 less and free from all defects. Wood with a slight odor 

 should be whitewashed to prevent the stored products be- 

 coming tainted. The lumber should be thoroughly dried
