Abstract

The invention relates to an energy efficiency evaluation method for a pipe-shell-type heat exchanger. The method comprises the following steps that an energy efficiency parameter of the pipe-shell-type heat exchanger is acquired; an energy efficiency characteristic function is established by adopting the energy efficiency parameter based on net energy exchanged by the pipe-shell-type heat exchanger; an optimal overall heat transfer coefficient of the pipe-shell-type heat exchanger is determined, and an optimal energy efficiency index is obtained in combination with the energy efficiency characteristic function. According to the energy efficiency evaluation method, the optimal energy efficiency index and an energy efficiency evaluation index can be obtained, and a basis is provided for heating power design of the efficient pipe-shell-type heat exchanger.

Description

technical field [0001] The invention relates to the technical field of heat exchanger energy efficiency evaluation, in particular to a method for evaluating energy efficiency of a shell-and-tube heat exchanger. Background technique [0002] A heat exchanger is a device for transferring heat between hot and cold fluids. It is an indispensable part to ensure the normal operation of industrial production. It occupies an important share in metal consumption, power consumption and investment. The heat exchange pressure vessel belongs to the high Energy-consuming special equipment. At the same time, the heat exchanger is one of the main equipment to improve energy utilization. Shell and tube heat exchangers are also called shell and tube heat exchangers. It is a partitioned wall heat exchanger that uses the wall of the tube bundle enclosed in the shell as the heat transfer surface. This kind of heat exchanger has simple structure, low cost, wide flow cross-section, and easy to ...
