Section, including frame shall not exceed 3,500 lbs. (excluding refrigerant).

2.4.2 Refrigerant shall be in accordance with A-A-58060A.

2.5 Performance Requirements

2.5.1 Operating Modes: The ECS shall have two states: “ON” and “OFF.” The “ON” state indicates that the ECS is powered and is controlling temperature and humidity. This is also referred to as the “operating” state, and includes the Start Up, Transient, and Steady-State sub states. The “OFF” state indicates that the ECS is not powered. This is also referred to as the “non-operating” condition. Storage requirements assume the ECS is in the “OFF” state.

2.5.1.1 Sub-States of the ON state

- Start Up sub-state: The ECS is on, but the temperature and humidity conditions in the ECS/CSU main compartment are outside the bounds. The EEU payload electronics cannot safety be energized when the ECS is in Start Up sub-state.

- Transient sub-state: The ECS is ON, and the temperature and humidity in the EEU/CSU main compartment are within the bounds, but not within the steady-state bounds. The EEU/CSU electronics can safely be energized while the ECS is in the TRANSIENT sub-state. The ECS may go from STEADY-STATE to TRANSIENT under the following circumstances:

a) a temperature change is commanded by the user.

b) an auto-restart occurs.

c) the heat load inside the EEU/CSU changes by more than 10%.

The ECS shall recover and return to STEADY-STATE within120 minutes.
