What Is Precision Air Conditioning And Why Is It Necessary?

What is precision split air conditioner and why is it must?

Compared to yesterday’s monolithic telephone system, these days’s worldwide communications network is a much more complex and constantly evolving cluster of interconnected systems. And with continually more mission-critical processes reliant on transmission accuracy and 100 percent uptime, the requirements for reliability and operation have never been greater. Precision AC Split is one cornerstone of a economically-designed support system for this network.

Communications network cooling desires differ from typical commercial or “relaxation” requirements, in the following significant ways.

Commercial cooling systems may be required to operate only during heats months and during normal performance hours. Communications sites, but, generate temperature 24 hours per day, 365 days per year, and so the cooling equipment must be able to work reliably when outdoor ambients are as high as 120degF or as low as -20deg. Because of this constant cooling requirement, the choice of reliable and electrical effective components are vital.

Unlike general commercial air conditioner systems, these precision ac split units are designed to run continually, require a small amount of maintenance, and offer precise manage of temperature and humidity. Standard air conditioners quickly lose efficiency and break under continual running.
Electronic Load

While completely cooling load is determined by the structure house, solar load, space pressurization or ventilation air, electronic equipment and people, the primary load in a communications site is normally the equipment. The primary loads in commercial website are normally people and ventilation air. In the process of cooling, largely air conditioners cool the air (sensible cooling) and eliminate moisture (latent cooling). Since electronic equipment does not release or absorb moisture, the ac split selected for a communications site need primarily cool the air, not take away moisture. The air conditioner necessary normally be selected with a “sensible temperature ratio” of no lower than 78 percent.

A system more typical of a commercial application, with a sensible temperature ratio of only 65 percent, could consume as much as 20 percent more power to cool the same site, and could make simpler humidity levels in the space to unacceptable levels.
Precision ac split is designed from the ground up to protect equipment, not people. “Luxury” air conditioning systems are designed for the relaxation of people, and simply cannot give the mild of environment required by high-running telecom equipment.

There are fundamental differences between standard and precision air conditioning…reasons why “people coolers” won’t protect equipment. People are far more tolerant of heat and humidity swings, whereas equipment requires precise levels of temperature and humidity maintained around the clock. This means weighty-duty systems and precision controls; people coolers don’t have either the strength or sensitivity for the work.

Heat Manage

The high density heat load in a telecommunications area is beyond the size of common ac split systems. Equipment is brilliant maintained in a stable environment of 72degF /-2degF (22.2degC /-1degC). As telecom equipment generates large quantities of heat in small areas, six to ten times the temperature density of normal office room, the split air conditioner system must have more than just enough cooling power.

It have to have the precision to react quickly to a drastic change in temperature load and prevent wide heat fluctuations, which is something a large house system cannot do.
Humidity Control
Telecommunications equipment should be protected from both internal condensation and static electricity discharges. Maintaining the exact humidity level in the computer area is just as vital as maintaining proper heat.

Too high a humidity could cause condensation within the telecom equipment and the potential for hardware hurt. If humidity is too cheap, static electrical could disrupt working or even shut down the telecom system. An frequent construction system cannot normally control the environment within these boundaries.
Air Volume

Telecommunications equipment requires greater air volumes than ordinary ac split can provide. Typical comfort systems are designed to supply in the midst of 300 and 400 CFM (cubic feet per minute) per ton of cooling. Telecom systems require amongst 500 and 600 CFM per ton. The high-density heat load in a relatively small room requires more changes of air than a less dense “relaxation” application. While a normal office area requires only two air changes per hour, a telecom room requires up to 30 changes per hour. Without proper air volume, hot spots and heat fluctuations could increase within the room. Also, greater air volumes provide the higher sensible heat ratios required by telecom equipment.
Air Filtration

Filtration of both area pressurization and recirculation air is critical in a communications site, and the air filter must have an “ASHRAE 52-76″ Standard Efficiency of no lower than 25 percent. This efficiency is much higher than normally provided in a commercial system.
