Shenzhen is one of the
great technological hubs of China
and the world, but it has a problem: the climate is almost tropical and it is very hot and humid almost all year round.
The solution is not to install more air conditioners in homes, businesses and shopping centers, but to
cool entire neighborhoods
with a large station that cools an entire neighborhood at a distance.
Those responsible for developing this idea is the company
Qianhai Energy Company
and the project has the support of Chinese public institutions.
Since its inception in 2014, the company has managed to install and operate 3 stations that, at the moment, offer air to businesses and public areas.
No private residences.
This is so because its operation lasts a long time and
it is only effective if it works more than 8 hours continuously
.
Since this is not the case in homes, those in charge prefer not to provide services to homes due to an energy saving issue.
Its objective is precisely that: not to spend so much energy on refrigeration and to centrally assume consumption in the warmest times of the year.
Preliminary reports suggest that these public air conditioners can
save about 130 million kilowatts of electricity annually
.
With the stipulated 10 stations, the city of Shenzhen expects to supply
400,000 tons of fresh air to an area of almost 20 square kilometers
of the city.
The big downside to this massive cooling system
is that it requires great planning and a very particular architecture for the cold distribution to be effective.
The recent construction of Shenzhen, which has grown exponentially in the last 20 years, allows this system to work efficiently.
