Dec 08, 2017 Each piece of HVAC equipment has a nameplate containing features and details. The problem is, this information is imbedded in the model number and must be interpreted to be useful. By learning to interpret the code, you can increase your ability to repair, test, diagnose, and sell upgrades. Carrier Nomenclature How To Read AndLets take a look at how to read and interpret equipment nomenclature. Carrier Nomenclature Download At TheExample is available as a download at the end of this article. These letters or numbers group equipment into categories such as furnaces or air handlers. Condensing units, heat pumps, cooling or heating coils, and package units also follow this pattern. Once you master the nomenclature of your favorite manufacturer, it becomes easy to find and learn others. One digit or number buried within the nomenclature can be trickier to spot than a sequence of numbers or letters. When testing, remember this is only a laboratory rating and rarely equals actual installed equipment performance. Once installed into a building, the effects of the distribution system bears on the equipment. Equipment is made to be installed in an upflow, downflow, or horizontal position.

For example, some manufacturers use numbers to represent nominal fan cfm capacity; 08 represents 800 cfm, 10 represents 1000 cfm and so on. Using this method, a 3 in the model number at the correct location indicates a 3-ton fan having a standard rated airflow of 1200 cfm. These correspond with the traditional 2, 2.5, 3, 3.5, 4 and 5-ton fan ratings at 400 cfm per ton. The components and features represented vary from one manufacturer to another and from one type of equipment to another. ASHRAE 205P is being developed to standardize manufacturer specifications and performance data as demand for access to this valuable data is increasing at an alarming rate.
