Abstract

Carrying out building block type alternant combination for multifunctional heat engineering integrative performance test unit, the method can be in use for carrying out following 8 items of relevant heat engineering experiment: mensurating performance coefficient of refrigeration cycle; available energy loss in heat transfer of temperature difference in heat exchanger; performance of cooling tower; intelligent controlling temperature of hot water tank; performance of condenser, performance of evaporating pipe, performance of cooling pipe, and performance of compressor. Full automatic computer test means are adopted in the invention so that dynamic changes of parameters to be tested can be observed visually. The method excitates students' interest in experiment to test parameters, process data, and accomplish whole procedure for measuring each performances.

Description

technical field [0001] The invention relates to an experimental method for teaching and scientific research, in particular to a thermal experimental method. Background technique [0002] With the improvement of the requirements for personnel training in the 21st century, many colleges and universities have gradually carried out and strengthened the construction of experiments. The current development of thermal experiment benches is as follows: [0003] The "Multifunctional Heat Transfer Experimental Bench" established by Wang Yao, Wang Gang and Kuang Guodong of Dalian University of Technology is mainly used for heat transfer analysis in chemical process. , also developed heat transfer CAI software including data acquisition, data processing and result output. The "Multifunctional Convective Heat Exchange Experimental Platform" designed and developed by Yunnan Wang Jing, Li Qinggang, Wang Xihua, etc., can be used to conduct professional and technical basic courses "Heat Tra...
