4.3.5 Learning ability

The intelligent air conditioner can continuously collect and sort the air conditioning process and air environment data in a certain period during the work process; it can accumulate a certain amount of data about the user's habits of using the air conditioner, the air environment data, the air conditioner's self-operating data, other third-party data; analyze the accumulated data to form a variety of air-conditioning operating strategies.

Note 1: The intelligent learning ability of intelligent air conditioners can be realized through the cloud or locally.

Note 2: Intelligent learning can be through autonomous learning or human assistant learning.

4.3.6 Feedback ability

The intelligent air conditioner can present the operating status of the air conditioner and the perceived environmental information to the interactive end through a human-computer interaction. The information fed back by the air conditioner can be actively pushed to the interactive terminal or can be queried through the interactive terminal. The information fed back by the air conditioner can be fed back to the interactive terminal. The information fed back by the air conditioner includes, but is not limited to, the setting temperature of the air 2018, it is 100 points; otherwise it is 0 point; recorded as alpha;

b) If meeting the clause 4.1.2 network and security requirements in GB/T 28219-2018, it is 100 points; otherwise it is 0 point; recorded as b;

c) If meeting the clause 4.1.3 electromagnetic compatibility requirements in GB/T 28219-2018, it is 100 points; otherwise it is 0 point; recorded as c.

The full score is 100 points. The actual result = alpha × 40% + b × 30% + c × 30%.

5.2 Evaluation of interconnection / interoperability
