Electronics Magazine

 

This issue of ELECTRONICS magazine featured a cover story on how the new Westinghouse Analog Recording Air-Conditioning Computer (WARAC) was "the first computer known to have been developed specifically for the determination of residential air conditioning loads".

The 4-page article includes drawings and pictures, one of which is the block diagram of the environmental and structural variables considered by the the computer. Another shows the "recording" of the fluctuations in daily temperatures.
