Selection of water-mixing connection structures and power analysis of pumps in heating system

Presents the suitable pressure conditions of six popular structures of water-mixing connection and the calculating methods for effective power of pumps. Compares the powers of pumps of available water-mixing connection structures in different pressure conditions, and discusses the selection of water-mixing connection structures. Analyses the energy-saving ratios of the optimal structures and the influence of water-mixing ratio on the energy-saving ratio. With a case, illustrates the selection of suitable water-mixing connection structure and its energy-saving ratio in heating system with constant flow.
