Built environment test technology course is established by using available heat exchanger experiment device. Vortex flow meter,pressure sensor and thermal couple are installed on the platform. Parameters such as heat exchange rate of exchanger,flow rate of cold(hot)water,circulation resistance of cold(hot)water side,temperatures of exits and entrances for cold(hot)water are gauged and these signals are collected by Agilent 34972A data logger.We take full advantage of available device and reduce expenditure of purchasing relevant equipment and promote teaching effect.
