Enable system for a controlled atmosphere system for a refrigerated container
First Claim
1. Apparatus for controlling the temperature and the atmosphere within a confined space comprising:
- a controlled atmosphere system for controlling the atmosphere within the space;
electrical control means for controlling operation of said controlled atmosphere system, said controlled atmosphere system control means being operative to control said controlled atmosphere system only when it is receiving an enabling signal;
a refrigeration system for controlling the temperature within the space;
a programmable electrical control means for controlling and monitoring the operation of said refrigeration system, said refrigeration system control means including, means for determining if the controlled atmosphere system should be operating, and, for generating a controlled atmosphere system enabling signal when said determination has been made; and
means for communicating said enabling signal from said refrigeration system controller to said controlled atmosphere system controller.

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.
