Conversion Formula:
| From: | To: |
The EER (Energy Efficiency Ratio) to kW/Ton conversion is a calculation used in the HVAC industry to convert between different efficiency metrics. EER measures the efficiency of cooling equipment, while kW/Ton represents the power input required per ton of cooling capacity.
The calculator uses the conversion formula:
Where:
Explanation: This conversion allows HVAC professionals to compare efficiency across different measurement systems and select appropriate equipment for specific applications.
Details: EER and kW/Ton are critical metrics for evaluating cooling system efficiency. Lower kW/Ton values indicate higher efficiency, while higher EER values indicate better energy performance.
Tips: Enter the EER value (must be greater than 0). The calculator will automatically compute the corresponding kW/Ton value. Higher EER values will result in lower kW/Ton values, indicating better efficiency.
Q1: What is a good EER rating?
A: For residential units, EER values typically range from 8-12. Higher values indicate better efficiency. Commercial systems can have EER values up to 16 or higher.
Q2: What does kW/Ton represent?
A: kW/Ton measures the power input (in kilowatts) required to produce one ton of cooling capacity. Lower values indicate more efficient systems.
Q3: How does EER relate to SEER?
A: EER measures efficiency at a specific operating condition (usually 95°F), while SEER (Seasonal Energy Efficiency Ratio) represents seasonal average efficiency under varying conditions.
Q4: What is a typical kW/Ton value for commercial systems?
A: Standard efficiency systems might be around 1.0-1.2 kW/Ton, while high-efficiency systems can achieve 0.6-0.8 kW/Ton or better.
Q5: Why is 12 used in the conversion formula?
A: The number 12 comes from the conversion between BTU/hr and tons of cooling (1 ton = 12,000 BTU/hr) and the relationship between watts and BTU/hr.
