Heat exchanger performance test and energy efficiency evaluation system

Abstract

The invention discloses a heat exchanger performance test and energy efficiency evaluation system. A to-be-tested platform is provided with an oil-water to-be-tested heat exchanger and a water-water to-be-tested heat exchanger; inlets of a hot oil loop and a hot water loop are respectively communicated with hot side outlets of the two to-be-tested heat exchangers; the steam loop comprises a steam-oil heat exchanger and a steam-water heat exchanger; the steam-oil heat exchanger and the steam-water heat exchanger provide exchange heat through steam; inlets of the steam-oil heat exchanger and the steam-water heat exchanger are respectively communicated with outlets of the hot oil loop and the hot water loop, and outlets of the steam-oil heat exchanger and the steam-water heat exchanger are respectively communicated with hot side inlets of the two to-be-tested heat exchangers; an outlet of the cooling water loop is communicated with cold side inlets of the two to-be-tested heat exchangers; an inlet of the cold water loop is communicated with cold side outlets of the two to-be-tested heat exchangers, and an outlet of the cold water loop is communicated with an inlet of the cooling water loop; and the data acquisition system comprises a plurality of detection sensors mounted on the pipeline.

Description

technical field

[0001] The invention relates to the technical field of heat exchanger performance testing, and more specifically relates to the measurement of flow, temperature and pressure of different working fluids, as well as the measurement and calculation of heat transfer coefficient and heat exchange resistance between different working fluids. Energy efficiency evaluation. Background technique

[0002] A heat exchanger is a device that transfers part of the heat of a hot fluid to a cold fluid, also known as a heat exchanger. With the increasing tension of energy supply around the world and the increasing awareness of natural ecological environmental protection, heat exchangers have been widely used, playing an important role in energy saving and consumption reduction. At the same time, due to the serious loss of energy consumption of some heat exchanger devices, it brings greater cost pressure to the operation of enterprises.

[0003] Therefore, it has very urgent ...
