VENTILATION. 



.The candling and breaking rooms should be furnished with a supply 

 of fresh, drj 7- air. If the plant is located where the humidity is com- 

 paratively low, a stream of fresh air can be forced into the rooms 

 through several layers of cheesecloth, by means of a suction fan. 

 The ideal method is the bunker system by means of which the air 

 is cooled on bunker coils and admitted through pipes into the breaking 

 and candling rooms. When this method is the only source of refrigera- 

 tion for the rooms, care should be taken that the bunker room is of 

 adequate size to provide sufficient refrigeration during the warm 

 summer weather. 



In small candling and breaking rooms refrigerated with brine coils, 

 an electric fan is usually suffieicnt to keep the air fresh, especially if 

 the doors are opened frequently for the admission or transmission of 

 material. The difference in temperatures within and without causes 

 a rapid change of air.
