     You must:

     • Make sure the total refrigeration load includes the loads imposed by all of the following:

     – Heat flow into the container caused by the temperature difference between both:

     ▪ The ambient temperature;

     AND

     ▪ The design storage temperature

     – Heat flow into the tank caused by maximum sun radiation

     – Filling the tank with ammonia warmer than the design storage temperature.

     • Provide emergency power capable of handling loads imposed by both of the following:

     – The temperature difference between the ambient temperature and the design storage temperature;

     AND

     – Sun radiation.

Note:

Emergency power is not necessary for facilities able to effectively vent vapors when the refrigeration system is not operating.
