What is the CSPF energy efficiency index on an air conditioner? What do they mean?

We often see on air conditioners with energy efficiency indicators such as EER or CSPF. This article will help you better understand the CSPF energy performance index. Let’s find out with Tnhelearning.edu.vn!

What is the CSPF Energy Performance Index?

CSPF (short for Cooling Seasonal Performance Factor) means all-season refrigeration performance index. The CSPF index tells us, for 1kWh of air conditioning consumption, how much cold air will be received from the device, including seasonal temperature changes in a year.

Like EER, CSPF is also a measure to evaluate the energy efficiency of air conditioners and air conditioners. The higher the CSPF value, the greater the cooling efficiency.

In our country, the whole-season cold efficiency index CSPF has greater practical significance in determining the energy efficiency of air conditioners, especially in the North because this area has winter.

How to calculate CSPF

CSPF = CSTL/CSTE

In there:

• CSTL is the total amount of heat that the air conditioner takes away from the air-conditioned space during the entire season.
• CSTE is the total amount of electricity consumed by the air conditioner in the whole season under survey.

What does the CSPF Energy Performance Index mean?

For consumers, the CSPF index is quite important in choosing to buy air conditioners. With the same product type, if consumers choose a product with a larger CSPF, it means that the air conditioner can save more electricity.

Compared with EER, CSPF is more accurate and closer to reality. Current new inverter air conditioners are also often measured and evaluated by CSPF index more than EER index due to its accuracy.

Hopefully with this article, Tnhelearning.edu.vn has provided you with a better view of the CSPF index. From there, you can choose to buy the most suitable air conditioner for your family. If you have any comments, please leave them below!
