WebMOTOR: PUMP: 1 EA FLA: 8.6 FAN: 1 EA FLA: 0.4 Where we have 10.4 amp from the compressor, 8.6 amp from the pump motor and 0.4 amp for the fan (water-cooled units still have a small fan to exhaust the heat from the case) for a total amp draw of 19.4 amp. Then we can convert amps to watts using the formula from above: WebSystem fan static pressure Fan motor efficiency Infiltration Reheat minimum airflow The Design phase will first assign the peak or block load calculated by the Load phase to the systems providing cooling. Once the loads have been assigned, the latent and sensible components of the loads are totaled and the sensible heat ratio

WebJan 7, 2009 · Check ASHRAE Handbook of Fundamentals, calculating heat load, internal gains. Essentially, for a motor in the airstream, it amounts to the full KW draw of the motor x use factor (how much is the motor running?). For a motor running 1/2 the time, use factor = 0.5. Usually amounts to 1.5 to 3 Deg temp rise. MintJulep (Mechanical) 7 Jan 09 11:36.
