摘要：T his article proposed a newm easurem ent m ethod for the fan coil water flowbased on pressure and tem perature.Firstofall,we have som e theoreticalanalyses to influencing factors offan coilim pedance S,m eanwhile,we carry out som e experim ents based on som e factors which influence the im pedance S, and we got the m ain factors influencing im pedance .T he last,we derived a com prehensive form ula of im pedance under the condition of the various factorsinfluence.Finally when we getthe experim entaldata,such aspressure△P、,tem perature Tw,we gotwaterflowQ. T his m ethod can realize fan coil flowm easurem ent on the water side in these cases of do not increase the fan coil resistance on the water side and lower investm ent of m easuring instrum ent. T herefore, it is suitable for the newair conditioning system ,and is suitable for existing air conditioning system energy saving transform ation.
