pcraturc 20° lower than the outside air for the month, an average of 

 about 5 kilowatt hours was used per day. The average milk load was 

 not high and being well precooled did not influence the temperature 

 and current consumi)tion as nuich as did tlie outside temperature. 



July. The outside temperature averaged 70°. With a moderate load 

 of milk the room temi)crature averaged 47°. Warm weather on tlie 

 21st and 22nd, coupled with the defrosting of the tank on the 23rd, pulled 

 the room temperature up over 50°. The current consumption to bring 

 this l)ack reached the high jioint of 12 kilowatts, or twice the average. 



August. The ten degree rise to 80° — 10° higher than the average for 

 the month — caused a five degree rise in the cold room temperature and
