The design and running of textile air conditioning spraying system constant pressure frequency converting control were discussed.Aimed at the problem of ineffective energy consumption increasing for the spraying pump caused by the simple adjusting method of spraying system in the sprinkling chamber of the textile mills,according to the operating performance curve rule of the water pump and pipe network and the basic theory of the water pump frequency converting control,adapting constant pressure variable frequency for the spraying pump control was put forward.With the adjustment method by adjusting the nozzle numbers in the spraying calandria work,constant pressure variable flow control of the water spraying volume was realized.It was proved by practical analysis that the effect of 22.8% yearly average energy-saving for the spraying system could be achieved by the constant pressure frequency conversion renovation of the spraying system in textile mills.It is considered that constant pressure frequency converting control of the spraying system can improve the thermal & humidity treatment effect of the spraying cham-ber.The regulation precision and reaction speed of the air conditioning control system are improved.Fine regulation of the air conditioning spraying system in textile mills can be achieved.
