The BTU ASHRAE measures that efficiency (and the resulting BTU output) at 80°F. 2 different units can have the same BTU ASHRAE; but, if they have a different temperature-efficiency relationship, the BTU DOE rating will be different.
4 Φεβ 2023 · When shopping for a portable air conditioner, you might have noticed two different BTU ratings on the packaging. Why are there two different numbers, and what do these ASHRAE and SACC ratings mean? A portable AC’s BTU (British Thermal Unit) rating measures the air conditioner’s cooling capacity.
19 Οκτ 2023 · The primary difference between ASHRAE and SACC BTU ratings lies in the testing conditions. ASHRAE provides a rating based on consistent, controlled laboratory conditions, while SACC offers a rating that considers the fluctuations in temperature and humidity that occur in the real world.
4 ημέρες πριν · Lower SACC BTU Ratings; Portable air conditioners will often have a lower SACC BTU rating compared to their ASHRAE rating. For example, a unit with an ASHRAE rating of 12,000 BTUs might have a SACC rating of 7,000 BTUs. This is because the SACC method accounts for the environmental factors that reduce the unit’s actual cooling ability. Energy ...
22 Ιουλ 2022 · What is the difference between BTU SACC vs ASHRAE ratings for portable air conditioners? The quick answer is that the new SACC ratings are an average of 30% lower than the ASHRAE ratings. For example, an LG portable AC with a 14,000 BTU has a DOE SACC of 10,000 BTU.
15 Ιουλ 2024 · Different testing methods lead to different air conditioner BTU ratings. Learn the differences between ASHRAE and SACC testing procedures to help you find the right AC for your space.
SACC stands for Seasonally Adjusted Cooling Capacity. It is based on the current testing standards that all currently manufactured portable air conditioners must display. The SACC BTU rating is always lower than the previous ASHRAE standard.
