Abstract

The invention discloses a low-temperature air-cooled heat exchanger performance detection testbed. The testbed comprises a reverse flow type wind tunnel, a temperature and humidity adjusting assembly,a refrigeration unit and a control cabinet, wherein the temperature and humidity adjusting assembly and the refrigeration unit realize the high-precision adjustment of wind speed, temperature and humidity in the wind tunnel under the control of the control cabinet. The testbed has the advantages of being large in temperature, humidity and wind speed adjusting range and high in control precision,is suitable for the environment with low temperature, low humidity and large concentration, and is particularly suitable for researching the heat exchanger performance under frosting conditions.

Description

technical field [0001] The invention relates to a heat exchanger performance detection test bench, in particular to a low-temperature air-cooled heat exchanger performance detection test bench. Background technique [0002] As an important equipment for exchanging heat between two fluids, heat exchangers are widely used in various links of national production, such as chemical industry, petroleum, power, food, air conditioning, boilers and many other industrial productions. They occupy an important position and are widely used. [0003] In recent years, with the continuous increase of energy and material costs, energy conservation and emission reduction has become an important strategic measure in my country, which has greatly promoted the research on high-efficiency energy-saving heat exchangers. Saving energy means a lot. [0004] Heat exchanger resistance, heat transfer capacity, mechanical properties and economic performance are important performance indicators of heat e...
