These days
Everyone has not been by the weather in the mountain town
"Flickering" is dizzy
18°C in the morning and over 30°C in the afternoon
The sun is shining today
Tomorrow it will rain heavily
Temperatures fluctuate
It's April
But let everyone
Tasted "the taste of early summer and late autumn"
I had to turn on the "put on and take off" mode
Gu Shiyun
There was no more cold after the rain in the valley
The world has warmed up
It doesn't matter if it's sunny or rainy
All kinds of work to welcome the arrival of summer
It's all time to prepare
Let's take a look at the air conditioner today!
In addition to refrigeration, the air conditioning system on rail transit trains also has a more important role of ventilating the semi-enclosed compartment environment. In order to ensure the normal use of the air conditioning system, in the daily train "train inspection" and "balanced repair" and other repair processes, maintenance personnel will clean, sanitize and maintain various filters of the train air conditioner and other equipment.
However, in addition to daily maintenance, the air conditioning system also has a "spring whole". The so-called "spring whole" means that after the train air-conditioning system has experienced long-term operating load in autumn and winter, the maintenance personnel will carry out more comprehensive inspection, cleaning and maintenance of the train air-conditioning system unit components, various relays, contactors, terminals, and air-conditioning drainage pipelines of the train air-conditioning system, so as to ensure the smooth operation of the train air-conditioning system in hot weather and provide a cool and comfortable riding environment for passengers.
In March every year, the train maintenance personnel of Chongqing Rail Transit will start the "spring rectification" maintenance work of the air conditioning equipment one after another, and the maintenance personnel during this period will become "beauticians" to make a deep "SPA" for the train air conditioning.
The "spring finishing" maintenance of a train air conditioner is divided into disassembly, cleaning, disinfection, reloading, inspection and other links.

The first is disassembly. The maintenance personnel will remove the roof air conditioning unit, the fresh air of the air conditioner, and the return air filter. Secondly, the individual parts are cleaned and disinfected. The maintenance personnel will use a high-pressure water gun to rinse the fresh air and return air filters of the air conditioner, and spray disinfectant to sanitize. For the inner cavity of the air-conditioning unit, evaporator and other locations that are easy to accumulate dust and cause poor refrigeration effect, they will use soot-blowing machines to carefully blow soot and remove dust to ensure the refrigeration effect of the entire air-conditioning unit. After the cleaning work is completed, the maintenance personnel will return all the accessories one by one and conduct relevant functional tests on the entire air-conditioning system to ensure the smooth operation of each air-conditioning unit.

At present, a total of 4,036 air-conditioning equipment has been maintained on the Ring Line, Line 1, Line 2, Line 3, Line 5, Line 6, Guobo Line, Line 9 and Line 10, and the air-conditioning maintenance work of other lines will also be started one after another. When summer comes, when the air conditioning in the carriage is fully turned on, the train after the "spring rectification" will bring you a cooler and more comfortable travel experience, let's look forward to it.
