摘要

Operation energy consumption of heat pump systems is one of the key problems for system design. This study establishes the models of transportation energy consumption ratio and transportation distance limit and puts forward the concepts of new economic specific frictional resistance. According to existing calculation formulas of specific frictional resistance, calculation formulas for more economic specific frictional resistance are deduced by combining with economic indexes. In this way, a range (30-400 Pa/m) of new economic specific frictional resistance is obtained to determine the transportation energy consumption ratio of water. On this basis, the pipe network is designed to reduce and control the transportation energy consumption ratio of pumps to 15%-20%.
