SYSTEM OF INTERNAL ENVIRONMENTAL CONTROL AND USES OF THE SAME
FIELD OF THE INVENTION The field of the subject matter of the present are the environmental control systems, specifically the internal environmental control systems, such as those used in exterior component cabinets, remote closure systems and / or remote access cabinets.
BACKGROUND The telecommunications and data communications industries have grown exponentially in the last 5 to 8 years, partly because both industries have been able to expand their client base of clients that are close to the center of operations / transmissions to clients that they are located at a significant distance from the operations / transmissions center. Also, many of the components used in the site of operations or in a remote site are more complex and are even smaller / more compact. The expansion of data transmissions to clients located at significant distances from the operations center is facilitated by remote sites that are portable and smaller than the center of the operations site. Both industries include those facilities and industries that
provide uni and bidirectional data transmission and transport. The telecommunications industry also includes wireless communications, wire-based communications and combinations thereof. Wireless communications include infrared, satellite, antennae, etc. Wire-based communications include fiber-optic cable, conventional cable, coaxial cable, shielded twisted-pair and unshielded cable, etc. The. sites and / or remote data and telecommunications sites usually contain connections and electrical components of telecommunications, such as batteries, antennas, circuit boards, keypads or other related components that in many cases can be fragile, relatively inaccessible and certainly sensitive to the elements and other environmental conditions. Therefore, those data and telecommunication sites, including remote sites, should be closed or otherwise contained in a protective enclosure system. Data and telecommunication sites, including remote sites, should be verified to identify system failures, such as sudden surge suppression modules, air conditioners and fans, power rectifiers, batteries and other user equipment with alarms. Additionally, verification must report changes to the site, such as interference in the cabinet, change 3
of temperature and humidity. Data and telecommunication sites, including remote sites, should also be environmentally controlled, such as with air conditioning, heating and humidity control, so that electrical and telecommunications components do not break down, short or degrade from another mode, leading to poor performance of the components or products. Remote closed systems also present other layers of complexity when reviewing viability at a remote site. If the remote site is smaller or otherwise restricted, the remote site must be sufficiently small and accessible. If the remote site is an area where there are environmental challenges, such as severe heat, rain, snow or extreme cold - the closed system or remote enclosure must be able to withstand environmental challenges, while being easily accessible and in which work easily Additionally, outdoor enclosure applications and / or closed or remote enclosure systems are typically provided with environmental control systems that provide heat exchangers or air conditioners, which are commonly powered by AC. Many of these environmental components are available in outdoor applications, but they are not equipped to handle the extremes of temperature that can be found in the environment.
outdoors or in the open. Due to the sensitive nature of the equipment and electronic devices, extreme heat can produce a thermal break at approximately 51.6 ° C (125 ° F). Additionally, if battery temperatures can be regulated at approximately 25.0 ° C (77 ° F), peak life and performance can be achieved. To optimize the performance of environmental control systems in outdoor enclosures it is necessary to isolate the interior of the enclosure making it as airtight as possible. However, this quality of air tightness can work against the goal of applying backup battery operation times of 2-8 hours when AC power is lost and / or AC-powered environmental systems are lost as well. The heat generating equipment operating in a sealed space with moderate to high outdoor temperatures will continue to raise the internal temperature until a thermal break occurs. This interruption condition can occur between 10-30 minutes, substantially less than the initial backup goal of 2-8 hours. On the basis of the disadvantages, disadvantages and cost problems of environmental control of a closed system or conventional enclosure, it would be useful to develop and implement an environmental control system that a) controls the internal space of the enclosure system or closed; b) provide multiple access points to facilitate the 5
repair and installation of equipment; c) is aesthetically functional given the structure of cable entry and routing; and d) it can maximize the life and performance of the battery, while maximizing the long-term use of the internal components and related electronic devices.
SUMMARY OF THE OBJECT MATTER An internal environmental control system for an outdoor closed system is described that includes: a) at least one air intake component coupled to the closed system to the exterior, b) at least one component of air exhaust coupled to the system closed to the outside, c) an environmental detection device; and d) an environmental regulating device coupled to the environmental detection device, at least one air intake component, at least one air exhaust component or a combination thereof, wherein the regulation device activates at least one of at least one an air intake component or at least one air exhaust component. Also described herein are methods for controlling the internal environment of a closed system or remote enclosure which include: providing an internal environmental control system; provide ambient air; and direct the environmental air through the internal environmental control system.

The environmental regulating device can also activate at least one motor coupled to the ventilation component and at least one air intake component, at least one motor coupled to the ventilation component of at least one air exhaust component or a combination of the same. In a contemplated modality, as mentioned at the beginning, an internal environmental control system can be used with any closed system or suitable enclosure, (such as a closed system or remote enclosure, another electronic enclosure or system arrangement of electronic components) . The enclosed or remote enclosure systems contemplated are described in the commonly owned PCT Application, Serial No. PCT / US02 / 34800 filed on October 30, 2002 and the US Requests Serial No. 10/481306 (filed in December). 17, 2003) and 10/793619 (presented on March 4, 2004, which is a continuation in part of 10/481306), all of which claim 12
Priority of the Provisional US Application Serial No. 60/379480 filed on May 10, 2002 and which are incorporated by reference in their entirety. But it should be understood that the contemplated internal environmental control system can be used in a number of closed-system or enclosure arrangements, including those that are designed for completely exterior, completely interior, or a combination of exterior and interior. A contemplated internal environmental control system eliminates the aforementioned thermal break condition, while allowing maximum battery run times over the available CD backup power - all without having great impact on operating times by inducing more load CD. Figure 1 shows a view of the enclosed or enclosed system 100, which in this case is a remote enclosure or closed system 110, with an internal environmental control system 120 comprising exhaust ventilation 112 and intake 114 operated by a fan controlled by an auxiliary motor. The remote enclosure or closed system 110 is similar to those shown and described in the filed applications referred to above, which have already been incorporated herein by reference in their entirety. It should be understood that the internal environmental control system maintains the nature of airtightness 13
air and the enclosure during normal power conditions and ventilation during the battery backup condition. Additionally, by controlling thermostatic between the auxiliary cooling system, two other performance problems can be solved: a) prevention of automatic operation at cold ambient temperatures, and b) activation in a normal energy mode in the case of environmental system failure principal. Other internal environmental control systems contemplated may comprise at least one of any or all of the following: an exhaust apparatus, an intake port, an auxiliary cooling device or device, auxiliary fans, auxiliary heating devices (for sub-freezing conditions) ), protective covers or coatings, warning lights and / or devices, conduits or air flow direction pipes, etc. Figure 2 shows another contemplated ventilation assembly 200 comprising a flap returned by a spring, controlled by a motor, 210 which is attached to an axle or rod 220 on a motor driven by AC 24V 230. A ventilation assembly also contemplated it comprises at least one fan hole 250 which engages or aligns in the fans mounted on the door (not shown). The ventilation mounting components 200 in this embodiment are at least partially enclosed by an enclosure of 14
NEMA 3R 240 vent. Flap 210 is normally closed by a high tension spring and the flap sits on a gasket 260 attached to the vent surface. Figure 3 shows the inside view of the door in Figure 1 illustrating two fans driven by CD 310. Figure 3 also shows a rail-mounted thermostat 320 and a 48V DC converter at 24V AC to 330. The system operates when the thermostat reaches the set thermal temperature, and therefore using the fans and driving the ventilation motors that open the intake and exhaust air. It was contemplated that the system will continue to operate until the temperature returns below the activation temperature. When this happens, the system shuts off the fans and the spring closes the flaps again sealing the vents. These fan assemblies can be chained to address variable cooling requirements when dictated by the application. Figure 4A and Figure 4B show a contemplated embodiment of the internal environmental control system 400 for a closed system or remote enclosure (not shown in its entirety). The air intake component 405 comprises a plurality of flaps 410 that are closed during normal operation of the components in the closed system or remote enclosure. When the temperature conditions of the internal environmental control system exceed a value of 15
pre-set thermostat, the air exhaust component 430 is activated and a plurality of fans and / or bellows 420 which constitute at least part of the air exhaust component 430 are activated by the environmental regulation device 440, which is a source of CD energy in this mode. A thermostat (not shown) acts as an environmental detection device in this mode. High temperature conditions, as discussed here, are typically caused by air conditioner failures or AC power failures. When DC power is applied, the fans expel air through the system, through at least part of the plurality of flaps in the component of that air station, which opens as a result of fan pressure, and the external deflectors via a labyrinth. When air is withdrawn from the closed system or remote enclosure, fresh air is brought to the enclosed system or enclosure via at least some of the plurality of flaps of the air intake component. At least some of the plurality of flaps of the air intake component open under the force of the pressure difference between the internal environment and the external environment (environment). Both the air intake component and the air exhaust component are designed to avoid external influence, such as wind, can cause it to open while the system is under normal operation.

Figures 7A-7C show another contemplated embodiment of the internal environmental control system where the system is coupled to at least two sides 702, 704 of a system closed to the outside, such as a closed system or remote enclosure (not shown in its entirety). If there are additional cabinets attached to the system closed to the outside, at least part of the internal environmental control system may be coupled to one of the walls or doors of the additional enclosure, or there may be multiple internal environmental control systems. As with the other embodiments described herein, the vent component may comprise a plurality of flaps on one or both of the air intake components or the air exhaust component to prevent recirculation of air. In this mode, the internal environmental control system is designed for systems with high static pressure loads.
17
The air intake component 710 may comprise a plurality of bellows (not shown) as inverse curved impellers, drawing cold air through a labyrinth filtered inlet 720 comprising an inlet cover 722, an inlet baffle 724 and a filter inlet 726, and expels air through the air exhaust component 730 located in the rear door 704 of the closed system to the outside, where the air exhaust component 730 comprises an exhaust door assembly 732 and a bellows assembly of exhaust fan 734. Each of the bellows in the air intake component comprises a type of "check valve" flap system, so that if one of the plurality of bellows fails, the flaps over the bellows failed they close automatically and avoid. that the air of another bellows recirculates towards the fan of the failed bellows. Also, in this embodiment, each bellows and the plurality of related flaps is in an autonomous replaceable module to allow its easy replacement, if necessary. Figure 7C shows the air flow 750 towards the air intake component 710 and outwardly 760 of the air exhaust component 730 in this contemplated embodiment. Table 1 shows the specifications for a contemplated modality comprising a remote enclosure or enclosure system; however, it should be appreciated that the system 18

For example, under "environmental" Table 1 shows that there is an air conditioner with a heater in the enclosure system or remote closed. A humidifier or dehumidifier may also be added to the system, or an air conditioner without the heater and vice versa may be present or added to the system. Another example would be a remote enclosure or enclosure system that can be designed to be smaller or larger depending on the needs of the remote site or the remote delivery site. If the enclosure or enclosure system is selected to accommodate at least one expansion enclosure then the internal environmental control system designed to accommodate the environmental needs of at least one additional enclosure is contemplated. At least one expansion enclosure may contain telecommunications components or electronic components that are subject to demarcation protection of the original remote enclosure system. At least one expansion cabinet is coupled to at least one frame system and / or at least one of the side panels in the coupling interface, which has already been previously described.
