To give you an idea of what the new rating should be (based on the old rating), we have created a conversion table from BTU ASHRAE to BTU DOE using the median 35% difference (rounded up to 100 BTU). This will illustrate how to convert from the old BTU ASHRAE rating to the new DOE BTU SACC rating.
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.
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.
To figure out exactly how big ducts you need for central air conditioning systems, we have prepared complete CFM duct charts for all different kinds of ducts: Duct sizing chart for flex ducts (round ducts with 5-20 inch diameter). Duct sizing chart for metal ducts (round ducts with 5-20 inch diameter).
4 Φεβ 2023 · 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. This is typically considered the most important factor when buying a new portable air conditioner.
This table defines the recommended minimum pipe insulation thickness based on the fluid design operating temperature range. The calculator located on the bottom of this webpage will determine an alternate insulation thickness outside of the stated conductivity range.
For example, a model previously rated at 14,000 BTU or 14K BTU (ASHRAE) is now considered a 10,000 BTU or 10K BTU (SACC) unit. What is the difference in the ratings? The ASHRAE testing was based on ideal situations whereas the SACC testing is based closer on real-life conditions.
