ھن ڳڻپيوڪر بابت

the cooling it starts from the U.S. EPA rule of thumb of about 20 BTU/h per square foot, then adjusts for ceiling height, sun exposure, occupancy and heat-producing rooms. For heating it scales the floor area by a BTU-per-square-foot factor that rises with a colder climate. So a 6,000 BTU/h need is about half a ton or 1.76 kW. This is a well-informed starting point for shopping: a proper HVAC load calculation (Manual J)The result is converted to tons and kilowatts and rounded up to a sensible unit size, using 1 ton of cooling = 12,000 BTU/h and 1 kW.The cooling adjustments are: scale by ceiling height relative to the standard 8 ft; subtract about 10% for a heavily shaded room or add 10% for a very sunny one; add roughly 600 × 20 = 6,000 BTU/hThe result is converted to tons and kilowatts and rounded up to a sensible unit sizeThe result is converted to tons and kilowatts and rounded up to a sensible unit sizeThe result is converted to tons and kilowatts and rounded up to a sensible unit sizeThe result is converted to tons and kilowatts and rounded up to a sensible unit sizeThe result is converted to tons and kilowattsThe result is converted to tons and kilowattsThe result is converted to tons and kilowattsThe result is converted to tons and kilowattsThe result is converted to tons and kilowattsThe result is converted to tons and kilowattsThe result is converted to tons and kilowattsThe result is converted to tons and kilowattsThe result is converted to tons and kilowattsThe result is converted to tons and kilowattsThe result is converted to tons and kilowattsThe result is converted to tons and kilowattsThe result is converted to tons and kilowattsThe result is converted to tons and kilowattsThe result is converted to tons and kilowattsThe result is converted to tons and kilowattsThe result is converted
