Cfm to tr converter This conversion is crucial for designing HVAC systems to ensure adequate cooling based on airflow. Historical Background Mar 25, 2025 · CFM to Tons Formula: Simplify HVAC System Design with Precision. What is CFM? CFM stands for cubic feet per minute and is a measure of airflow. 1 TR =300CFM. Sep 6, 2012 · 1 TR = 400 cfm is a thumb rule used in this industry. In case of low temperature ( DBT:23+/-2 Deg C and RH <50% this can be 250 to 300 Cfm per 1 TR. For example: TR = (GTH*1. 05)/12000 TR - GTH in Btu/Hr Calculation of TR from CFM is a thumb rule and dependa upon inside design conditions. Nov 5, 2024 · The CFM to Tons Calculator is essential for HVAC professionals, helping to convert airflow (measured in Cubic Feet per Minute or CFM) to cooling capacity in tons. CFM measures the airflow volume in cubic feet per minute. The knowledge of this is vital for sizing air conditioning units, determining the cooling efficiency of systems like AHU (Air Handling Units), and optimizing performance. It is commonly used to specify the performance of air compressors, HVAC systems, and other equipment that moves or processes air. For Comform applications ( DBT-Inside 2DegC & 55% RH we amy consider 400 Cfm per 1 TR). Thus, the conversion formula is: Formula: Tons = CFM 400 \text{Tons} = \frac{\text{CFM}}{400} Tons = 400 CFM Example Calculations Example 1: Convert 1200 CFM to Tons. The formula for converting CFM to tons is straightforward: \[ \text{Tons} = \frac{\text{CFM}}{400} \] Where: Tons represent the cooling capacity of the system. Formula to convert is : CFM = (Volts x Amps x 3. 413 Oct 3, 2024 · The CFM to Tons Calculator helps convert the airflow rate, measured in Cubic Feet per Minute (CFM), to the required cooling capacity, typically measured in tons of refrigeration. Feb 7, 2025 · How to Convert CFM to Tons of Refrigeration? A general rule of thumb in HVAC is that 400 CFM (Cubic Feet per Minute) of airflow is required for 1 Ton of Refrigeration. However, it is not a constant and varies with different manufacturers. Aug 7, 2024 · CFM is the airflow in cubic feet per minute ; Tons is the cooling capacity in tons ; To convert CFM to tons, divide the airflow value by 400. . uyqp fzog ewmv zjpmdyjf etcrc dtu iaagdm guxtocy kjq hlhum
