Abstract


This article studies the characteristics of parallel pump operation in the pump load time considering the frequency number , on the basis of the pump performance curve , pipeline characteristic curve and electricity , and many other factors , the preparation of the variable speed pump schemes analysis software . This software can be of general fluid transmission and distribution system and air conditioning , secondary pumping system variable flow regulator of many programs for technical and economic analysis and comparison , designed or modified to provide technical support for the project , and can be calculated in a variety of situations each pump 's operating parameters , provided in accordance with the actual control dig . Secondly, the use of this software gives the example of an air conditioning secondary pump frequency control programs , detailed in the example given various possible frequency control programs in each pump 's operating parameters , as well as various speed control program saving rate and payback period . For air conditioning pump system , taking into account the chilled water / cooling water variable flow chillers cooling performance , its variable flow operation simulation . This article also discusses the air conditioning secondary pump system and a pump system with variable flow control strategy .
