Hi sifus, i am comparing Midea and Sharp 1HP R32 inverter aircond.
Sharp: BTU=9700, power=890w, 5 stars rating
Midea: BTU=10000, power=755w, 4 stars rating

EER=BTU/power
Why Sharp has lower EER but higher stars rating?

your  figures seem  something not right  nod.gif

use  EER ,    check  the  AC spec  for this value.  the higher the more powersaving.

How is EER calculated?
The air conditioner EER is its British thermal units (BTU) rating over its wattage. For example, if a 10,000-BTU air conditioner consumes 1,200 watts, its rating is 8.3 (10,000 BTU/1,200 watts). The higher the rating is, the more efficient the air conditioning unit is. However, a higher rating is usually accompanied by a higher price.
from shopee
Power Supply (V-Hz-Ph) 220-240V~ ,50Hz, 1Ph
Cooling Capacity (Btu/h) 9500
Power Consumption (W) 880
Running Current (A) 3.8
Weighted EER (Btu/h/w) 10.45
Energy Efficiency Star Rating 3

Sorry, i forget to put the links in my earlier post.

Sharp: https://my.sharp/products/air-care/ahx9ved2?v=1149
Midea: https://www.lazada.com.my/products/midea-10...i768154307.html

Sharp EER=9700/890=10.9 (website put 5 stars rating)
Midea EER=10000/755=13.25 (picture shows 4 stars rating)

My calculation is correct right? I am confuse why Sharp one higher stars rating.
