The updated heat pump efficiency metrics are similar to the ones you know, but focus on practical considerations for real-world performance.
Advancements are always being made when it comes to increasing energy efficiency. We’re here to help you stay up to date on all the latest changes, including the newly introduced metrics for measuring heat pump efficiency:
Seasonal Energy Efficiency Ratio 2 (SEER2): SEER2 provides an evaluation of a heat pump’s efficiency throughout a cooling season. It measures the total heat removed from the conditioned space. A high SEER2 indicates the heat pump is very efficient in air conditioning mode.
Energy Efficiency Ratio 2 (EER2): EER2 focuses on the efficiency of a heat pump at a specific moment in time, providing a snapshot of its performance under steady-state conditions. The higher the EER2, the more efficient the heat pump is.
Heating Seasonal Performance Factor 2 (HSPF2): HSPF2 evaluates the efficiency of a heat pump during the heating season, considering both the energy consumed and the heat produced.
These sound the same as the heat pump efficiency ratings you’ve come to know, don’t they? The key difference is the introduction of the M1 testing procedure.
Introducing the M1 Testing Procedure
Heat pump efficiency ratings were adjusted to include the M1 testing procedure in order to better reflect the field conditions of heat pumps that have already been installed. The procedure increases the systems’ external static pressure by a factor of five. This change ensures that the ratings align more closely with the real-world scenarios faced by the equipment.
With the implementation of the M1 testing procedure, the corresponding SEER2, EER2, and HSPF2 new metrics were created. These metrics allow consumers and industry professionals to understand the system’s efficiency and performance in cooling, steady-state conditions, and heating.
Benefits of the New Heat Pump Efficiency Metrics
The key benefits of the new heat pump efficiency metrics include:
- Accuracy in Real-World Conditions: SEER2, EER2, and HSPF2 subject heat pumps to conditions that are closer to those encountered in actual installations. This ensures that consumers can make informed decisions based on the equipment’s real-world efficiency in various scenarios.
- Improved Performance: The incorporation of M1 testing allows heat pumps to perform more reliably and efficiently in the environments where they are installed, whether it’s for cooling, steady-state conditions, or heating.
In addition, the introduction of the M1 testing procedure contributes to a more accurate and transparent assessment of HVAC systems. Overall, these metrics help provide practical tools for measuring energy efficiency in our everyday lives, helping consumers make informed decisions about their heat pump purchases.
