| The Dangers of IT Equipment Overheating | The Solution : Spot Air Conditioners |
| Electronics equipment can suffer both short-term and long-term effects from overheating. |
If an air-conditioning system does not keep the temperature low enough, the equipment in the data center may continue to function and show no signs of overheating, but its life cycle may be considerably shortened, adding to investment costs.
In situations where the cooling capacity of the air-conditioning system is inadequate, severe overheating can quickly occur, especially if there are several or more racks of equipment, which can generate a large amount of heat.
As the temperature rises to the danger level, servers, which contain a company’s critical data, will usually shut themselves down to prevent possible damage or data loss. Network routers, which handle a company’s internal and external data transmissions, such as e-mail and telephone communications, are even more heat-sensitive. Overheating can permanently damage them, requiring costly replacement.
Potentially even more costly than equipment replacement, however, is system downtime. If a downtime occurs, all business activities and transactions supported by the electronics equipment come to a halt, sometimes with devastating results.A relatively new class of commercial portable air conditioners, called portable spot air conditioners or portable spot coolers, provides a convenient and cost-effective way of cooling office data centers. Portable spot air conditioners can be used in leased spaces, where installation of a precision-cooling system or mini-split may not be allowed. Because they are portable and are therefore designed to hold up under hard use, these units are often even more rugged than permanent systems. In fact, many portable units have been in operation for 20 years or more, with only minimal maintenance. There are two basic types of portable spot air conditioners: air-cooled and water-cooled. Although water-cooled air conditioners are more efficient than air-cooled ones, they use high-pressure water lines that can leak. Consequently, along with portable evaporative coolers, which can also leak, they are usually considered too risky to use with IT equipment. For the purposes of this paper, therefore, the terms “portable air conditioner” or “portable spot cooler” refer only to air-cooled systems.
| How Spot Industrial air conditioners Works |
| Split air-conditioning systems consist of two separate units. One is the outdoor unit containing a compressor, condenser coil and hot-air exhaust fan. The other is the indoor unit, containing an evaporator coil and cool-air delivery fan. Spot air conditioners, on the other hand, are self-contained systems, combining a compressor, condenser coil and evaporator coil in a single unit. Within the unit, cold refrigerant flows through copper tubing from the compressor coil into the evaporator coil. A fan blows over the evaporator coil, pushing cool air out. A second fan pushes hot exhaust air out through flexible ducting, which is usually directed into the crawl space above a drop ceiling. |
Excess moisture removed from the air collects in a small condensation tank, which can be emptied manually or, with most models, automatically via a pump.
Key Points
The most important benefit of portable spot air conditioners is that they allow quick and easy installation that does not involve construction. This gives them a lower cost than other systems, and also means they do not violate most lease agreements. Installation, which does not normally require prior approval of the building owner, usually consists of no more than rolling a unit in, removing a drop-ceiling panel and positioning the exhaust duct in the space, which the panel previously occupied. Another important benefit of portable spot air conditioners is their flexibility. Whenever necessary, they can be quickly and easily moved to a different place in the data center and their airflow redirected. This is particularly helpful if any new hot spots develop, such as when equipment is added or racks are reconfigured. Also, if the business moves to a new location, unlike permanently installed air conditioners, the portable units can be taken along, eliminating the need to invest in new equipment. In addition, manufacturers offer portable spot air-conditioner models with the same type of convenience and safety features found on permanent units. These include the ability to communicate with the data center or building’s monitoring and control systems, and to receive automatic safety shutoff commands from the building’s fire-alarm control panel.
