Computers operate best when the room temperature is cooler. The more computers you have the more heat you must deal with. There are several factors used to determine the proper size portable air conditioner needed to satisfy the heat load in a computer room, so please accumulate the following data as it pertains to all equipment in your computer room, telecommunications equipment room or electrical panel so we may accurately serve you When you have compiled this data it is time to visit our Cool Estimate page to determine the proper sizing of the equipment to cool your room. After determining the appropriate Model or if you would like one of our staff to assist you, call us and we will assist you in getting the right equipment for your application. Our toll-free number is 1-800-807-5798.
What is the total wattage of the equipment to be cooled. This is determined by multiplying Amperage x Voltage (i.e. 20 amps 230V power 4,600 Watts)
What is the size of the room to be cooled? (length, width, height)
Are personnel in the room most of the time? If so, how many?
Are there any windows in the room? If so, how large are they and which direction do they face?
What is the room construction? (wood and sheetrock, concrete block, etc)
Is the room insulated? What is the R-value of the insulation
What is on the other side of the 4 walls of the room (equipment cabinet) to be cooled? (i.e. Is the area adjacent to your cooling project cooled with air conditioning or is it a furnace with extreme temperatures?)
Decide on an Air-Cooled or Water-Cooled Model. See the explanation of the difference in air or water cooled.
Now, visit our BTU calculators and choose the calculator that is right for you.
Please remember when comparing portable air conditioners from different Manufacturers the advertised cooling capacity can be very different based on the temperature and humidity levels used in the Laboratory tests (this laboratory testing has everything to do with the advertised BTU capacity the manufacturer is stating but has nothing to do with the the conditions in which the air conditioner will operate). The cooling capacity, BTU (British Thermal Unit), can be determined by several methods so before you purchase know how the BTU values for the Air Conditioner you are purchasing are determined. Two (2) common rating methods are as follows:
80 degrees and 50% relative humidity
95 degrees and 60% relative humidity
What causes the same identical machine to have such different values? It is because the higher temperature and humidity levels increase the ability of the refrigerant to absorb heat which increases the cooling capacity. Again, this has to do with determining the advertised btu of a particular machine and has nothing to do with its ability to operate in a particular operating environment.
This evaluation process is performed in a Laboratory where the rating conditions are very specific. A return air plenum is put on the Evaporator and the Condenser to insure the air coming into the unit is exactly the right temperature and exactly the correct humidity level. It is during this precise testing process that the BTU ratings are established. The same identical machine can advertise different BTU ratings just by using a different set of values in the rating process (i.e. 65,000 at 80 degrees and 50% relative humidity and 84,000 btu when tested at 95 degrees and 60% relative humidity).
Since the same machine can be sold as a 65,000 btu or an 84,000 btu machine you should know what you are buying. If you need 84,000 btu but only get 65,000 btu you have not solved your cooling requirement. Also, be aware that the warranty on the compressor is different from one Company to another (some are 5 years others are 3 years). Use our Comparison Chart in determining the value of one unit and the other.
