ABSTRACT:
A refrigerated container is provided which has a refrigeration system and a controlled atmosphere system. The refrigeration system and the controlled atmosphere system are both provided with electronic controllers. The refrigeration controller is programmed with certain acceptable conditions under which the controlled atmosphere system will be allowed to operate. When these conditions are satisfied the refrigeration controller will send an enabling signal to the controlled atmosphere systems controller allowing it to operate. If at any time during operation the refrigeration controller determines that the controlled atmosphere system should not operate, it removes the electrical enabling signal, causing the controlled atmosphere system to stop.
