Influence of fans on building air conditioning energy consumption

Taking control region of indoor air velocity under fan air adjustment condition as study basis, simulates the influence of fan air adjustment on velocity field in typical buildings by means of CFD software. Taking PMV as evaluation index for thermal comfort, studies the coupling relationship among air velocity, temperature, etc., under the working condition of air conditioning with and without fan air adjustment under typical human body activity status. Obtains the indoor temperature value meeting thermal comfort standards with fan air adjustment. Analyses the influence of fan air adjustment measures on the energy saving of buildings and the potential of energy saving. Puts forward several suggestions for the energy saving of buildings.
