How to Read What Ton AC Unit I Have Within an air conditioner a specific substance known as a refrigerant is changed between gaseous and liquid states by applying pressure changes within a sealed system. This process is called refrigeration. Refrigeration capacity is measured by how much heat can be moved within a given period of time. One unit of measure for this capacity is British thermal units (Btu) and another is tons of refrigeration (ton). The Btu rating of all AC units or systems is stated on a label or data plate on the machine. It should be easy to find. Once the Btu rating is known, it can be converted to tons of refrigeration. Locate the outdoor part of the AC unit. If it is a split system, with an air handler within the building and a condenser unit outside, the data plate or label displaying the Btu rating will be on the condenser unit, outside. If it is a package unit, all in one housing, that will be outside. It should be close to the an outside wall, in a painted metal housing.

Unless it is water-cooled, it should have an obvious electric fan in it. Locate the data plate or label, which will be about 3 inches by 4 inches in size, applied flatly to the surface of the housing. It will be a metal tag, riveted to the outside of the housing, with information stamped onto it, or a stick-on label, with information printed on it. Find the Btu rating. The label will state the manufacturer, model number and serial number. It will also state the voltage, amperage and wattage ratings of the AC, as well as the Btu rating. ac motor control circuits projectsThe Btu rating is the figure that you need.why is my ac unit clicking Convert the Btu rating to tons of refrigeration.how to protect outdoor ac unit

One ton of refrigeration is equal to 12,000 Btu of cooling capacity. Therefore, the Btu rating divided by 12,000 equals the ton rating. Formula: Btu ÷ 12,000 = tons Example A: The label states that the cooling capacity is 36,000 Btu. Divide the 36,000 by 12,000. The answer is 3. The ton rating is 3 tons. Example B: The label states that the cooling capacity is 18,000 Btu. 18,000 divided by 12,000 equals 1.5. The ton rating is 1.5 tons. If the data plate or label showing the information needed is not in plain view, it might have come off or been removed. The information you are seeking might be on a label or technical data sheet inside the housing. Before opening the housing, disconnect electrical power to the unit as there are exposed high voltage components inside. This can be done by turning off the circuit breaker in the building's electrical panel, or pulling the disconnect located near the outside AC unit.

ENERGY STAR products usually exceed minimum federal standards by a substantial amount. The ENERGY STAR logo is on all qualified products that meet specific standards for energy efficiency. ENERGY STAR-qualified products exceed the federal minimum standards for efficiency and quality -- sometimes significantly. Look for the label on appliances, electronics, water heaters, windows, and other products that consume energy in your home. To help you figure out whether an appliance is energy efficient, the federal government requires most appliances to display the bright yellow and black EnergyGuide label.

Although these labels will not show you which appliance is the most efficient on the market, they will show you the annual energy consumption and operating cost for each appliance so you can compare them yourself. How to Read the ENERGYGUIDE Label The EnergyGuide label is required to be placed on all appliances by the manufacturers. The label provides information about energy consumption, and shows you how much energy an appliance uses compared with similar models. Keep in mind that the numbers are averages: actual costs will differ somewhat depending on how you use them. The label shows the following: Maker, model number, and size of the appliance. Estimated yearly operating cost (based on the national average cost of electricity), and the range of operating costs for similar models. The ENERGY STAR® logo indicates that this model meets strict criteria for energy efficiency. Estimated yearly electricity consumption. Key features of the appliance and the similar models that make up the cost comparison range.
