Celantel’s need to discover.
In 1977 Telettra Spa patented the world’s first passive shelter.
The invention concerned a TLC shelter station able to ensure the functioning of the radio equipment housed in it, in environmental conditions varying from – 55° a + 40°, without the use of air conditioning devices with energy consumption.
The same was used for No. 64 stations of the Trans-Siberian ( BAM project URSS)
Inventors: Amos Bazzoli, Enzo Celant, Guido Scagliotti.
The shelter inside has a configuration in which the three functions performed by the passive air conditioning system are included. In this way the traditional logic of heat exchange of the passive system components is inverted.
Formulation derived from the previous patent of 1997 for higher internal dissipations suitable for sub-zero temperatures.
Metal structure to support shelter for GSM stations to be placed on the terraces of the buildings making the installation independent from their bearing capacity.
System with internal/external passive exchange micromodules inserted into walls or ceilings.
Mini “serial” modules for the storage and internal thermal exchange in plastic material, integrated together according to the power to be dissipated.
Semi-passive module to be placed inside the shelters close to the wall and interacting with the external one through a sealed aeration circuit, such as to guarantee the hermeticity of the same.
Metal module incorporating in a single gauge the three functions necessary for each passive system i.e exchange with the external environment, exchange with internal one and accumulation.
It refers to a container for electric and electronic apparatuses, equipped with a device for the passive or semi-passive conditioning of rooms, in particular, a pole for containing electric and electronic apparatuses for cellular phones.
It refers to a pole for telecommunications, in particular for cellular phones, adapted to contain electric and electronic apparatuses and equipped with a system for passive or saemi-passive conditioning which uses a special external heat exchanger.
It refers to a pole for telecommunications, in particular for cellular phones, which has also the function of containing electric and electronic apparatuses. In particular, it equipped with a device for passive or semi-passive conditioning so to containing the increase in temperature.
Module which can be combined with existing shelters in order to convert them into passive air conditioning and, therefore, gaining the advantages deriving from this.
