NL1024256C1 - Tunnel network cooling system, especially for underground train network, uses trains to shift locally cooled air through tunnels - Google Patents

Abstract

Cooling equipment is installed in the tunnels and/or in intermediate regions between the tunnels and/or on the trains themselves and used to supplement the so-called plunger effect in which cooling is brought about by the trains shifting masses of air as they travel through the tunnels. In this system, locally cooled air is shifted by the trains.

Description

COOL SYSTEM FOR TUNNEL NETWORK

Large cities are generally equipped with tunnel transport networks, which make it possible to transport people efficiently from A to B.

5 These tunnel systems have become of vital importance for large cosmopolitan centers.

Most of these tunnel transport systems were built at a time when the transport requirement was considerably lower than the current time required. Nowadays many more people are being moved in these 10 tunnel networks.

Nevertheless, these networks remain a very strong transport alternative for travel in metropolitan areas.

Due to the increased quantities of people to be transported, the temperature development has also increased sharply. The total tunnel system has become warmer, especially in those spaces that are far away from the central air supply.

People and means of transport can be seen as moving continuous heat sources.

This greatly reduces the comfort for passengers and can even lead to life-threatening situations.

The traditional cooling and ventilation facilities currently in use are not sufficient to provide the entire network with cooler air quickly, energy-efficiently, safely and affordably.

. 25 As a result, the only option for reducing the temperature is to use fewer means of transport and to transport fewer people. This is of course an impossible alternative.

The strength of the current systems, on the other hand, is that the network is essentially one large air pump, the objects moving through the tunnels functioning as plungers moving air through the entire network. This uses little additional energy: the objects drive fresh air everywhere in the network.

Unfortunately, this effect is not large enough to cause the higher temperature to be reduced quickly enough.

The invention relates to the combination of the existing "plunger system", which provides general air ventilation within a tunnel network, with cooling equipment to be installed locally, which in the interstices and / or 40 in the tunnels and / or in the moving objects regulates the air present there in temperature.
