Ningbo Metro has been "available in the hot and cold zone" from today. Do you think it is necessary?

Beginning on August 10, the Ningbo Rail Transit has implemented the temperature control mode of the train carriage. A train, the four -section of the head and tail is the "strong cold area", the middle carriage is "weak cold zone", and the temperature difference between the "strong and weak cold" carriage is about 2 ° C. On the morning of the 10th, the reporter saw at the Sakura Park Station of the Metro that the indicator of the "Strong and weak and cold carriage" was posted on the platform door.

"In order to meet the differentiated needs of different passengers on the temperature of the train and improve the comfort of passengers, we borrowed the innovation moves of cities such as Beijing, Guangzhou." It has always been a hot topic of everyone. The Ningbo Metro has implemented a "partition temperature control", which is also a exploration of differentiated public services.

At the scene, the reporter also randomly interviewed several passengers. The "post -90s" Xiao Jin is a classmate. He believes that the Ningbo Metro's move is "intimate". Xiao Jin said: "I'm more afraid of heat, and I will definitely choose a strong cold carriage, but it may be more suitable for the elderly and children." Student Shi is a college student at school. When I wear skirts to sit down for a long time, I will feel cold. Now the subway has the function of "hot and cold selection". This setting is very humane.

Of course, there are also passengers admitting that they do n’t feel much about the temperature difference in the compartment, and they feel that they are almost the same. In this regard, the reporter learned that although the "strong and weak and cold" compartment carried out temperature control, "strong cold" was controlled at 24 degrees, "weak cold" was controlled at 26 degrees, but unlike civil air conditioners, the air conditioner of the subway carriage was air -conditioning. Temperature cannot always be absolutely constant. Because the train is repeatedly shuttled in various environments such as elevated, ground, and underground, at the same time, the temperature of the carriage will be frequently exchanged by the hot and cold airflow inside and outside the door, the density changes of the high and low peak passenger flow, the physical sensing and demand differences of long and short passengers. The influence of factors, so the physical temperature of different passengers is still different.

Will the "strong and weak cold" compartment be promoted for a long time? It is reported that the trial plan of the Ningbo Metro's "strong and weak" compartment is this year's high temperature season. Whether the subsequent implementation will be implemented for a long time, it will be determined in conjunction with citizens' feedback and operating actual assessment during the trial period.
