A more satisfactory arrangement for refrigerating 
with ice is to have the ice house take the place of the 
ice chamber shown in Fig. 3714. This, of course, requires 
an ice house with the same degree of insulation as that 
of the refrigerator itself, because no saw dust is used 
in packing the ice.

house dispenses with the handling of ice, produces bet- 
ter circulation and therefor results in a drier and cooler 
refrigerator. The increased circulation is due not so 
much to the larger mass of ice with which the air comes 
in contact as to the greater height of the ice house. Cir- 
culation may be reduced, if desirea, by regulating or 
closing the opening at the ceiling by means of a slide 
or register.

of 40° F. may be maintained in a simple ice box, con- 
structed as shown in Fig. 38.
