PASSIVE COOLED SHELTERS
Telecommunication and general electronic equipment normally require carefully controlled climatic conditions when installed inside the shelter.The passive conditioning system is based on the exploitation of physical phenomena such as thermal capacity, thermal isolation and heat transmission.
The Passive Conditioning System, suitably dimensioned is extremely reliable and has an operational life span which is usually longer than those obtainable with standard active conditioning systems. The use of passive conditioning shelters is possible in desert and other geographic areas where there are big thermal differences between night and day.
The use of passive conditioning shelters is a must when the provision of commercial power is not currently available and it has to be produced locally with expensive systems such as:
- solar cells
- aeolian generators
- generating sets
and where maintenance is difficult and expensive to carry out, such as in desert or remote areas.
Results
The passive conditioning system allows the total control of the internal climatic conditions (temperature and humidity) resulting in:
- • significant reduction in operating costs
- • reduced maintenance
- • complete isolation of the interior from the external ambient
- • reduction of the internal thermal oscillations
- • improved equipment lifetime.
Omnishelter ® propose two different types of passive conditioning:
• PICS
- • Passive Integral Conditioning System, which doesn't require any power supply for its operation.
- • Passive Enhanced Conditioning System, which allows an increase in the overall efficiency of the temperature control and can be used when a very small portion of electrical power generated locally (typically limited to a few watts) can be made available for this purpose.
All the elements constituting a passive cooling system are housed in a separate subsystem, structurally independent from the main structure, which can be packed and shipped separately with substantial savings in freight costs. As an additional advantage, the configuration of the passive cooling systems does not reduce the internal available area for the installation of the other equipment.
In order to guarantee the safe operation of the equipment, Omnishelter ® take all possible measures to prevent intrusion of insect, dust, sand or other particles inside of the shelters. The experience gained in supplying shelters world-wide allows Omnishelter ® to select and combine many various solutions in order to guarantee the highest reliability and durability of the system.
