High altitude derate
WebAltitude can have an effect--but probably from two mechanisms... One is temperature--Above ~5,000-7,000 feet, many electrical devices need power derating because there is less dense air and less cooling effect. The other is that many batteries have a pressure vent and less air pressure will let the batteries vent at low pressures.

ACF * (Actual gas BTU content / 950) * 3,000,000 BTU/H input 2,499,000 BTU/H * .87 (87% full load efficiency) = 2,174,130 BTU/H corrected output B) Benchmark 3000 Boiler applied at an altitude of 7,000 ft. and the gas BTU content is 850 Web81%. 90%. When the component needs to be de-rated for both temperature and altitude, the de-rating factors given in the respective tables should be multiplied together. When a component, like liquid-cooled FC, has both air- and water-cooled parts, derating should be calculated for both parts of the respective ambient- and coolant temperatures.

However, as mentioned before, as the altitude increases, the air becomes a poorer insulator and the spacing distances have to be increased per the following table (assuming an 8 mm clearance at 2000m). As can be seen from this table, if a power supply is to be …
WebAt higher altitudes, less-dense air has a reduced capacity to insulate against flashover. Most electronics are designed to operate at altitudes up to 1000-2000 metres. Above this, it may be necessary to purchase electronics such as speed controls designed specifically for use at high altitudes.

Assuming the 20% de-rate, your 24000BTU outdoor unit would deliver 19200BTU and your 24000BTU indoor head would be able to deliver 19200BTU. If you combine the two, you end up with a 19200BTU system, not 40% down. the paint mixer salt lake cityWebIn electronics, derating is the operation of a device at less than its rated maximum capability to prolong its life.
