The temperature curve is the average of the mean 24-hour temperatures. Referring to the curve showing the variation in the supply of milk from month to month, it will be noted that there is practically a fixed relation between the temperature of the air and the supply of milk. The average of the milk supply, which is taken as 100 per cent, is available during April and September, while the maximum occurs during June. The highest summer temperature occurs the latter part of July and the first of August, and the maxi- mum amount of work to be done by the refrigerating plant is during July. Therefore the condi- tions existing at this time should be taken as a basis for determining the size of the re- frigerating plant required. If the capacity of the refrigerat- ing plant is sufficient to han- dle the maximum load run- ning eight hours a day, it will handle the average load run- ning four hours a day. The time of running the machine will decrease from a maximum of eight hours during July until it can be shut down entirely in the Northern States during December, January, and Feb- ruarj^. In the South it will be necessary to operate the refrigerating plant to some extent during the entire year. The curve marked "compres- sor curve" shows the approx- imate daily hours the compres- sor will have to be operated to produce sufficient refrigeration to take care of the milk during the different months of the year. This curve, however, is based on the milk supply and weather conditions existing in the Northern States, where the dairying industry is prin- cipally located at the present time.
