Web8 de jul. de 2002 · Heat dissipation would be a concern at high altitudes. But the largest reason equipment is derated is because the dielectric strength of air decreases as the altitude increases. As the dielectric strength decreases then a potential of 500 volts at sea level may perform fine but at 10000 feet it may flashover. Web4 de set. de 2024 · Each unit de-rates according to altitude. 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. WebDensity Change at High Altitude. At sea level, the density of air is .075 lbs/ft 3 (1.19 kg/m 3), see Table 1. This value is created by all of the other molecules in the atmosphere weighing down on the molecules at sea level. As the elevation increases, there are fewer molecules weighing down and the density of the air decreases. porthbeer cove
