Convert Tons of Refrigeration to BTUs per Hour
A ton of refrigeration is approximately equal to 12, BTU/h or kW. History/origin: The ton of refrigeration originated around the s during the transition from stored natural ice to mechanical refrigeration. A ton of refrigeration is a unit of power sometimes used in the United States. It is defined as the energy put off by melting a ton of ice every 24 hours, and is approximately 12, BTUs per hour.
Whether you own a home or a business, you can easily figure out your air conditioning needs once know some HVAC rules of thumb. We help Las Vegas residents with their cooling needs. Call Us Unfortunately, this can cause far more problems than it solves. HVAC units are designed to run uninterrupted for long periods, during which time they can remove what to wear glacier hiking alaska humidity while cooling your building.
If the HVAC unit is too large, it will constantly stop and start, leading to a decreased lifespan for your HVAC unit along with humidity problems inside your building. In order to determine the right amount how to make foot orthotics AC for your building, a contractor will do a Manual J calculation. If you are thinking about replacing your HVAC unit, you can conduct your own estimate to get an idea about your cooling needs.
For example, each ton of air conditioning can remove 12, BTUs from a building in an hour. A commercial building will have radically different HVAC needs than a residential one. They generally have higher roofs, greater foot traffic, and different insulation, which can radically alter calculations.
There is much variation among commercial buildings as well as some require far more cooling needs than others. However, in many cases, one ton of air conditioning what happened to you lyrics remove about 12, BTUs from square feet in an hour. You can use this to determine the cooling load of your building and the minimum size of your HVAC unit.
Commercial buildings will likely have higher foot traffic than residential spaces, so add BTUs to your calculation for every person who works inside a building.
Every window facing sunlight will also add 1, BTUs to your estimates. Every additional kitchen in your building will add another 1, BTUs to your calculations. In order to calculate how much air conditioning you will need, divide the square footage of your building by Then, multiply this number by 12, BTUs, and then add to that number the additional heat generated by windows, workers or how many btu per ton of cooling such as kitchens.
This number will provide you with a good idea of the size of the air conditioner you will need. Some companies now divide the square footage by 1, which can give you a range of values for your HVAC needs. Given the higher cooling needs of commercial buildings, commercial HVAC will have different costs than residential.
You can expect to pay anywhere between 1. This can increase dramatically if you run a business that generates lots of heat. Residential buildings have different air conditioning needs than larger commercial spaces. Given the Las Vegas climate, this number can reach a maximum of about square feet per ton for most buildings. Many of the same rules of thumb that apply for larger commercial spaces also apply for residential ones.
One major difference is one ton of air conditioning capacity will cool more square footage. Given our climate zone in Las Vegas, if you have a square-foot home, you can expect one ton of air conditioning to cool about to square feet. Each section will contain about 12, BTUs that need to be removed per hour, similar to commercial spaces. Assuming the minimum cooling capacity of square feet per ton for your HVAC unit, a square foot home will require 4.
Your HVAC unit will need to remove about 4. If your home is square feet, you can calculate your HVAC needs the same as you would for a square foot home. Your air conditioner will need to be able to remove this much heat from your home per hour to keep a stable temperature. While your calculations can give you an idea of what you would expect to pay, a host of factors could change what your building needs.
If you buy an HVAC unit that produces too much cool air, it could have a shorter lifespan and your building might face problems with humidity.
An expert can conduct a more detailed assessment, which you can compare with your own. About Service Area Why Us? April 26, Categories: Uncategorized. Contact Our Cooling Specialists.
How Can We Help You Today?
Apr 26, · Assuming the minimum cooling capacity of square feet per ton for your HVAC unit, a square foot home will require tons of air conditioning to cool. Your HVAC unit will need to remove about x 12, BTUs, or 48, BTUs, per hour to keep your home cool. Calculate BTU/hr. BTU/hr. = Gallons per hr x x?T°F; Calculate tons of cooling capacity; Oversize the chiller by 20% Ideal Size in Tons = Tons x ; You have the ideal size for your needs; For example, what size chiller is required to cool 40GPM from 70°F to 58°F??T°F = 70°F - 58°F = 12°F; BTU/hr. = 40gpm x 60 x x 12°F. Mar 05, · Thus, a 2, square foot area with two windows, four regular occupants, and one kitchen would have a BTU of 52, This would require tons of AC or square feet per ton. This is close to the square feet per ton sizing of the HVAC industry in Chicago and Orlando, but you will notice the variance due to us adding a kitchen and windows.
Below, we offer a summary for finding the correct HVAC tons per square foot in commercial and residential buildings. Most single unit houses require 1 or 2 tons of AC, but in commercial buildings, you will require far greater AC infrastructure.
If your AC system is too small, then it will take longer for it to remove heat from your building. In practical terms, this means that the AC will run longer and consume more energy. However, if the AC system is too large, then it will never run at full efficiency and, as a result, will consume more energy than necessary. This is because buildings retain and lose the amount of heat and cold air at different levels i.
Furthermore, you must also factor in how occupants will use the AC system throughout the year. These are both complex calculations that will result in a peak heating load figure and a peak cooling load figure. You need these figures to ensure your HVAC system runs efficiently. You should not use average figures to determine the final size of your air conditioner and heating system, but rather, to get a rough idea of the scope.
They will then calculate the BTU by dividing the space in square feet by and then multiplying its answer by 12, Thus, a 2, square foot area with two windows, four regular occupants, and one kitchen would have a BTU of 52, This would require 4. This is close to the square feet per ton sizing of the HVAC industry in Chicago and Orlando, but you will notice the variance due to us adding a kitchen and windows.
The industry standard is a benchmark, but not a firm rule. For example, buildings in hot climates will get hotter i. However, buildings in cold environments have a different issue, which is to retain heat, not remove it. Moreover, as noted earlier, failing to calculate the right size of your HVAC units can cause major operational issues. These include costlier operating costs and, potentially, more frequent HVAC maintenance and repair work.
Additional variables affecting your calculations include the type of HVAC system. For example, with an Underfloor Air Distribution UFAD system, you can diffuse cool air closer to people and, as a result, use less energy and require less time to cool the space.
