The Ningbo Metro will control the temperature from the carriage today!How's the effect?Reporter visits on the spot!

On August 10, the Ningbo Metro tried on the entire train carriage to officially implement the zoning temperature control mode. How's the effect? The reporter made a special visit.

Temperature difference is about 2 ℃

On the morning of the 10th, the reporter saw at the Sakura Park Station that the indicator of "Strong Cold, Weak and Cold Carry" was posted on the platform door. Among them, the "strong cold" carriage was located at the head and tail of the train carriage. Located in the middle of the train.

The temperature difference between the "strong and weak" carriage is about 2 ° C. Zhao Mengyao, the relevant person in charge of the Ningbo Rail Transit Transportation Center, introduced: "On the platform door of each side of the platform, we posted the guidance and prompts. When passengers were waiting for the car, we could choose different compartments to ride according to the prompts."

"Partition temperature control" does not mean that the temperature of the carriage is constant

Although the Ningbo Metro has launched a "strong and cold" carriage to control temperature control, unlike civil air conditioners, the air conditioning temperature in the carriage cannot always be in a constant state.

Trains are repeatedly shuttled in various environments such as elevated, ground, and underground. Because of the different conditions, the environmental temperature has been changing dynamically. At the same time, the temperature of the carriage is also affected by the frequent exchange of hot and cold airflow inside and outside the stop switching door, the density changes of the high and low peak passenger flow, the physical sensation of the long and short passenger, and the difference in demand. As a result, the physical temperature temperature of different passengers is still different.

Differential exploration of public services

The air -conditioning temperature of the subway car has always been a topic of discussion. The implementation of the "partition temperature control" of the subway is the embodiment of differentiated public services and a useful exploration.

Zhao Mengyao said: "We launch the" partition temperature control ", such differentiated services allow passengers to find the 'comfort zone' and enhance the travel experience. This is the first attempt since the opening of the Ningbo Metro. Traveling is more 'temperature'. "

"Strong and weak cold" carriage question and answer

1. Does it be promoted for a long time?

At present, the Ningbo Metro's "Strong and Cold" carriage trial operation plan is in the high temperature season this year. 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.

2. How to ensure that the air conditioner is running normally?

In order to ensure that everyone can have a comfortable ride environment, the maintenance personnel of the Ningbo Metro regularly check, maintain, eliminate and clean the air conditioners in the station and the carriage.

Before the train goes online, the driver will also check the train air conditioning function, and it will go out to carry passengers after confirming that it is correct.

3. How to choose the carriage?

In the process of ride, if the temperature is high, you can go to the "strong cold" compartment at both ends of the train. If the temperature is low, you can choose to go to the "weak cold" car in the middle of the train.
