Electric Household Refrigeration 



The average size of all units 

 was 15.7 cubic feet of total 

 contents and 11.3 cubic feet 

 of food storage space. An av- 

 erage of 30 percent of the total 

 space in the refrigerators was 

 occupied by the chilling unit. 



The average size of the four 

 usual household type ma- 

 chines was 10.5 cubic feet of 

 total contents and 7.2 cubic 

 feet of food storage space. 



All the common types and 

 qualities of insulation ordina- 

 rily encountered were repre- 

 sented, ranging from a simple 

 double wood wall, with no 

 special insulation of any kind, 

 to the modern heavily insulat- 

 ed type. 



The table of refrigeration 

 specifications shows consider- 

 able variation in the other 

 details and conditions which 

 prevailed during the tests.

The refrigerator- on Farm Xo. 1 is a steel cabinet with white lacquer 

 finish, insulated throughout with cork-board, trimmed with nickel- 

 plated hardware, and furnished with castor glides. (Fig. 2). The in- 

 terior is lined with hard-baked white enamel and equipped with heavy, 

 rust-resisting, removable wire shelves. 



The entire equipment is located in the kitchen, a room 8 feet wide 

 and 16 feet long, without direct heat from a stove or furnace. An elec- 

 tric range is used for cooking. In winter the room is heated indirectly 

 from the furnace by way of the dining-room door. The room tempera- 

 ture is about the normal temperature that is maintained in a home.

The refrigerator on Farm No

 construction consists of an inner and 



outer wall of % inch matched hard pine sheathing, varnished on the 

 outside, on a frame-work of studding. An air space and one or two 

 layers of building paper are between the walls. No special insulation 

 is used at any point. An outside icing door, without gaskets, opens on-

 operated. The interior is made entirely of unfinished hard pine
