Why is a Portable Air Conditioner called a Spot Cooler ??

LinkedInPinterestTwitterShare

As the term Spot Cooler implies, the portable air conditioner can only effectively cool one spot or area. Portable spot coolers are not meant to replace central air conditioning. The spot cooler is meant to supplement, or in emergency situations take the place of central air that has been shut off due to maintenance, theft of critical components or break down. The spot cooler can be placed in the right position to cool the person or equipment as needed for these situations. At times, computer rooms (server rooms) and other areas need supplemental cooling. This is a perfect fit for the spot cooler. The spot cooler is brought in to help the existing central air system without the cost of a major equipment upgrade.

Is the portable air conditioner the only equipment that could be called a spot cooler? No because other types of spot coolers are available. The evaporative cooler that is manufactured by Port-A-Cool® is the best example of a spot cooler that is not a portable air conditioner. These evaporative coolers will effectively cool many areas that a portable air conditioner can not cool due to the size of the area. The evaporative cooler can lower the temperature of the air 10 to 25 degrees. The cost to run the Port-A-Cool® spot cooler is also much less than that of portable air conditioners. A typical Port-A-Cool® spot cooler can be run for less than $1 per day.

So for all your spot cooler needs remember to call an expert. Spot Cooling Systems has been in business since 1984 providing spot coolers for rent and purchase. Please call us 24 hours a day 7 days a week. 866-990-5700

What is a portable air conditioner?

LinkedInPinterestTwitterShare

Portable air conditioners are, of course, portable.  A portable air conditioner is used to supplement, replace, used in an emergency, and back up situations.  Some server rooms out grow their permanent air conditioning system. A portable air conditioner is used to supplement the system providing an inexpensive solution to cool the server room.  In the situation where an air conditioning system needs to be replaced but the cost is prohibitive, the portable air conditioner is a viable alternative that is less expensive than a complete system replacement. In times when the primary air conditioning system is offline for maintenance, or breakdown, Portable air conditioners will be brought in on a temporary basis providing the cooling that is needed.  Some entities like to have a portable air conditioner standing by just in case of an emergency.  These units will be placed where needed and not turned on until an emergency happens and the portable air conditioner is needed.

The portable air conditioner has all the same components that your home or office air conditioning system has only it is fully self contained and on casters for easy deployment.  When installing a portable air conditioner you must remember that it needs a place to exhaust the hot air that is removed for the space to be cooled. A portable air conditioner must have somewhere to place the heat that is removed in order to cool the room.  Most commercial applications only require a portable air conditioner to be vented through the ceiling via a hot air duct connected to a ceiling panel.  In some cases the hot air can be duct-ed out a window.  Also, portable air conditioners, in an emergency can be vented out a door, assuming the adjoining space is not occupied.

Cooling Strategies for IT Wiring Closets and Server Rooms, Part 2

LinkedInPinterestTwitterShare

Let’s understand that our problem to solve is heat removal, rather than supplying cold air.  If heat is not removed, the heat in that space that houses IT equipment will accumulate and raise the temperature.  Remember that every kilowatt of heat used by your IT equipment creates a kilowatt of heat power that must be removed.  And to remove it we need to allow for, or create a channel to move it to a colder place.

Heat can either flow through the walls or ceiling of the space.  It can flow to cooler air via a grille or a vent that could have a fan to assist the movement of the airflow.  Heat can also be removed by your building’s air cooling system or removed by a dedicated air conditioner.

Portable spot coolers from Spot Cooling Systems are an excellent, economical choice for cooling your IT wiring closet or server room.   They are available in many different sizes to meet the demands of your equipment and space.

Portable Cooling Strategies for IT Wiring Closets and Server Rooms, Part 1

First we must specify the appropriate temperature at which we must maintain for the proper operation of your equipment.  IT equipment manufacturers usually provide a maximum temperature in which their devices are designed to operate and to guarantee performance and reliability.  This temperature is usually 104 degrees (40C). 

This is the maximum.  Operating at that temperature generally will not provide the same level of performance and longevity as operating at lower temperatures.  Because of this, IT equipment manufacturers publish a recommended operating temperature for their equipment.  Recommended operating temperatures are between 70F (21C) and 75F (24C) with the goal of no higher than 77F (25C).

The ExtraCooler portable air conditioner is available in various sizes and electrical voltages to meet every wiring closet and server room needs.  Spot Coolers are perfect for maintaining the recommended operating temperatures in your IT Closet or Server Room.  They are mobile, easy to operate and built to last.  For everyday, weekend, emergency or contingency planning, give us a call and your cooling needs will be taken care of by the experts at Spot Cooling Systems. 

Environmental Threats and Their Costs. The Series

LinkedInPinterestTwitterShare

The most common environmental threats to server rooms are temperature, humidity, water leaks, human error, intrusion, vibration, and power outage. Many of these threats, such as temperature and humidity, are related, which complicates environment monitoring and heightens the need for an automated, sophisticated system.

This series on Environmental Threats and Their Costs starts with the biggest threat to computer hardware, temperature.

Temperature

Temperature is the main environmental threat to computer hardware. The generally accepted, ideal temperature is between 68 and 74 degrees Fahrenheit (20 to 24 degrees Celsius).

Excessive heat degrades network performance and causes downtime. As the temperature increases, a heat sinks fan works harder to cool the central processing unit (CPU). Continuous overworking causes the fan to fail, leading to a machine overheating. A machine shuts down when it reaches an unsafe temperature in order to prevent permanent damage. An administrator must then be located, day or night, go to the machine, and reboot it after it has cooled. Consequently, services hosted by a down machine are unavailable until it is restarted, which can take minutes or hours. If the server hosts critical services (e.g., e-commerce, user validation, email) that are not distributed to backup servers, revenues can be lost, users cannot login, and communications are interrupted. If the shut down is not done properly, data can be lost.

Excessive heat and rapid temperature changes also damage equipment. Rapid temperature increases can increase humidity, while rapid drops can cause water in humid air to condense on equipment. Together, heat and moisture accelerate the break down of materials used in microchips, motherboards, and hard drives, which is called premature aging. In worst cases, a machine won’t shut down when the temperature exceeds safe levels, and circuits are damaged. Ultimately, heat-damaged equipment must be replaced, increasing the cost of network maintenance.

Controlling temperature is becoming more important and more difficult because of changes in equipment design and greater use of network services. New equipment runs hotter because it runs faster and does more work. Also, more circuits are placed closer and closer together, trapping heat in a smaller space. Smaller equipment also means that more equipment can be placed in the same space, usually packed tighter together. The increase in density of equipment causes a rise in the amount of heat dissipating in a rack cabinet. Increased network usage also increases heat, so as usage levels change during the day, so does the temperature and the need for cooling. For networks that operate near capacity 24 hours a day, every day of the year, there is little, if any, time for machines to cool down.

Green Computing

LinkedInPinterestTwitterShare

Green computing or green IT, refers to environmentally sustainable computing or IT.It is  ”the study and practice of designing, manufacturing, using, and disposing of computers, servers, and associated subsystems—such as monitors, printers, storage devices, and networking and communications systems—efficiently and effectively with minimal or no impact on the environment. Green IT also strives to achieve economic viability and improved system performance and use, while abiding by our social and ethical responsibilities. It’s resultant of global warming but actually it is ‘Desktop Warming’.

To comprehensively and effectively address the environmental impacts of computing/IT, we must adopt a holistic approach and make the entire IT lifecycle greener by addressing environmental sustainability along the following four complementary paths:

Green use — reducing the energy consumption of computers and other information systems as well as using them in an environmentally sound manner
Green disposal — refurbishing and reusing old computers and properly recycling unwanted computers and other electronic equipment
Green design — designing energy-efficient and environmentally sound components, computers, servers, cooling equipment, and data centers
Green manufacturing — manufacturing electronic components, computers, and other associated subsystems with minimal impact on the environment

Background information: The U.S Environment Protection Agency launched energy star’, a voluntary labeling program in year 1992, which is designed to promote and recognize energy-efficiency in monitors, climate control equipment, and other technologies. This resulted in the widespread adoption of sleep mode in computers and electronics popular among consumer electronics. The term “green computing” was probably introduced after the Energy Star program began; there are several USENET posts dating back to 1992 which use the term in this manner. Concurrently, the Swedish organization TCO Development launched the TCO certification program to promote low magnetic and electrical emissions from CRT-based COMPUTER DISPLAYS; this program was later expanded to include criteria on energy consumption, ergonomics, and the use of hazardous materials in construction. The Organisation for Economic Co-operation and Development (OECD) has published a survey of over 90 government and industry initiatives on “Green ICTs”, i.e. information and communication technologies, the environment and climate change. The report concludes that initiatives concentrate on greening ICTs rather than tackling global warming and environmental degradation through the use of ICT applications. In general, only 20% of initiatives have measurable targets, with government programmes including them more frequently than business associations.Many governmental agencies have continued to implement standards and regulations that encourage green computing. The energy star program was revised in October 2006 to include stricter efficiency requirements for computer equipment, along with a tiered ranking system for approved products. More than 26 US States that have established state-wide recycling programs for obsolete computers and consumer electronics equipment. Green Computing Impact Organisation (GCIO) is a non-profit organization dedicated to assisting the end-users of computing products in being environmentally responsible motivating community of environmentally concerned IT leaders who pool their time, resources, and buying power to educate, broaden the use, and improve the efficiency of, green computing products and services. Members work to increase the ROI of green computing products through a more thorough understanding of real measurable and sustainable savings incurred by peers; enforcing a greater drive toward efficiency of vendor products by keeping a community accounting of savings generated; and through group negotiation power.

It is becoming widely understood that the way in which we are behaving as a society is  environmentally unsustainable, causing irreparable damage to our planet. Rising energy prices, together with government-imposed levies on carbon production, are increasingly impacting on the cost of doing business, making many current business practices economically unsustainable. It is becoming progressively more important for all businesses to act (and to be seen to act) in an environmentally responsible manner, both to fulfill their legal and moral obligations, but also to enhance the brand and to improve corporate image. Companies are competing in an increasingly ‘green’ market, and must avoid the real and growing financial penalties that are increasingly being levied against carbon production.

IT has a large part to play in all this. With the increasing drive towards centralized mega data centers alongside the huge growth in power hungry blade technologies in some companies, and with a shift to an equally power-hungry distributed architecture in others, the IT function of business is driving an exponential increase in demand for energy, and, along with it, is having to bear the associated cost increases.

How to Contribute in Green Computing

As computers play an ever-larger role in our lives, energy demands, costs, and waste

are escalating dramatically. Consider the following from the Climate Savers Computing

Initiative:

In a typical desktop computer, nearly half the power coming out of the wall is wasted

and never reaches the processor, memory, disks, or other components. The added heat from inefficient computers can increase the demand on air conditioners and cooling systems, making your computing equipment even more expensive to run. Even though most of today’s desktop computers are capable of automatically transitioning to a sleep or hibernate state when inactive, about 90 percent of systems have this function disabled. Some 25 percent of the electricity used to power home electronics—computers, DVD players, stereos, TVs—is consumed while the products are turned off. Turn off your computer at night so it runs only eight hours a day—you’ll reduce your energy use by 810 kWh per year and net a 67 percent annual savings. Purchase flat-screen monitors—they use significantly less energy and are not as hard on your eyes as CRTs.Purchase an Energy Star–compliant computer. Note that laptop models use much less energy than desktop units.  Plug your computer into a surge protector with a master control outlet, which automatically senses when the computer is not in use and cuts power to it and all your peripherals. Plan your computer-related activities so you can do them all at once, keeping the computer off at

other times.  Consider a smaller monitor—a 14-inch display uses 40 percent less energy than a 17-inch one. Enable the standby/sleep mode and power management settings on your computer. Forgo the screen saver—it doesn’t save energy or your screen unless you’re using an old monochrome monitor. Review document drafts and e-mails onscreen instead of printing them out. Power off your monitor when you are not using it instead of using screen savers. Consider using an ink-jet printer—although a bit slower than laser printers, inkjets use 80 to 90 percent less energy. Buy vegetable or non-petroleum-based inks—

they are made from renewable resources, require fewer hazardous solvents, and often

produce brighter, cleaner colors.  Turn off all printers and peripherals unless you are using them. Do not leave the computer running overnight or on weekends. Choose dark backgrounds for your screen display—bright-colored displays consumer more power.  Reduce the light level in your room when you are working on your computer.

Network and share printers where possible. Print on recycled-content paper. Look for non-chlorine bleached papers with 50 to 100 percent post-consumer waste. Use double-sided printing functions. E-mail communications as an alternative to paper memos and fax documents.

Create Green Machines:

Activating the power management features on your computer saves energy and money while helping the environment. Your computer’s SLEEP and HIBERNATE settings are two of the most effective ways for you to make your computer more environmentally friendly. You can activate these functions manually or through your operating system’s pre-set power management settings.

Sleep Mode

Sleep or standby mode conserves energy by cutting off power to your display, hard drive, and peripherals. After a pre-set period of inactivity, your computer switches to a low power state. When you move your mouse or press any computer key, you exit sleep mode and your computer takes you back to its previous operating state. Sleep mode is an especially effective way to conserve battery power in a laptop computer. However, if your computer loses power for any reason while in sleep mode, you may lose unsaved work.

Hibernate Mode

Hibernate mode saves energy and protects your work by copying system data to a reserved area on your hard drive and then completely turning off your computer. It also reduces wear and tear on your components. When you turn power back on, your files and your documents appear on your desktop just as you left them. Be sure to set your system to automatically go into hibernate mode any time your battery power reaches a critically low level.

Calculating Server Room Heat Loads

LinkedInPinterestTwitterShare

Priceless corporate data and tens of thousands of dollars of server room equipment can quickly be at risk for loss if server room temperatures aren’t maintained correctly. Because server room equipment releases so much more heat than any other office location, portable air conditioners are the ideal solution for cooling the server room by being location specific with your critical cooling requirements.

Server room cooling needs

Before purchasing air conditioners for a server room, you’ll need to calculate how much heat must be displaced. With the excessive amount of heat produced by the server room equipment, you can’t choose a portable air conditioner based on the general square foot recommendations alone. Instead, you’ll need to pay attention to the entire BTUs generated in the server room.

In principle it’s easy to calculate the size of air conditioning unit you’ll need for your server room just add together all the sources of heat and install an air conditioning unit that can remove that much cooling. In practice however, it’s rather more complicated.

Calculating The Heat Load

The amount of heat generated is known as heat gain or heat load. Heat is measured in either British Thermal Units (BTU) or Kilowatts (KW).

1 KW is equivalent to 3412 BTUs. 12000 BTU = 1 Ton of Cooling Capacity

Factors Include:

  • The floor area of the room
  • The size and position of windows, and whether they have blinds or shades
  • The number of room occupants (if any)
  • The heat generated by equipment
  • The heat generated by lighting

To calculate the heat load you will need the following information.Room Area BTU = Length (m) x Width (m) x 337

    • South Window BTU = South Facing window Length (m) x Width (m) x 870
    • North Window BTU = North Facing windows Length (m) x Width (m) x 165
    • If there are no blinds on the windows multiply the result(s) by 1.5.
    • Windows BTU = South Window(s) BTU + North Window(s) BTU
    • Total Occupant BTU = Number of occupants x 400
    • Equipment BTU = Total wattage for all equipment x 3.5
    • Lighting BTU = Total wattage for all lighting x 4.25

Total Cooling Required

Add all the BTUs together

Room Area BTU + Windows BTU + Total Occupant BTU + Equipment BTU + Lighting BTU = Total Heat Load

Total Heat Load divided by 12000 = Total Cooling Tonnage

For example if the calculated BTU = 16400 BTU then 16400/12000 = 1.36 Total Cooling tonnage required. Since the requirement is 1.36 Tons you would consider using our SCT18, 1.5 Ton unit to cool your server room.

Choosing A Unit:

Portable air conditioners, also called spot coolers, are ideal for server room cooling because they focus a lot of cooling energy exactly where it’s needed.

Considerations:

What type of outlet power is available?

Spot Cooling Systems, Inc. makes this calculation simple.

Our 1 Ton SCT14 and 1.5 Ton SCT18 units operate off standard 115 volt, 60 Hz, 1 phase, power on a 15 Amp circuit.

Our 2.5 Ton SCT30, 3.5 Ton SCT42 and 6.5 Ton SCT83 operate pm 208-230 Volt, 60Hz, 1 phase power on a 20, 30, 60 Amp circuit respectively.

The 5.4 Ton ECHD65 operates on 208-230 Volt, 60 Hz, 3 phase power on a 40amp circuit and the 6.5 Ton SCT83B unit uses 460 Volt, 60 Hz, 3 phase power on a 20 Amp circuit.

Is Your Server Room Firewalled?

All Spot Cooling Systems portable air conditioners discharge the heat removed form the room to an open ceiling cavity. In the case of a firewalled server room that heat has nowhere to escape. The simple solution to this is to install a firewall damper to which duct work can be attached to allow heated air to discharge to an open location.
