风道式气-气换热设备热工性能检测装置

Detection apparatus for thermal performance of air duct type gas-gas heat exchange equipment

Abstract

本发明公开了一种风道式气-气换热设备热工性能检测装置,其特征是分别设置第一风道和第二风道;第一风道和第二风道呈水平交叉布置,第一风道和第二风道的结构设置均为:自风道入口起依次串联设置加热段、稳流段、测试段、试件、方圆过渡段和风机,构成气流通道;气流通道自风道入口至方圆过渡段的入口位置均为矩形横断面;第一风道和第二风道是以试件为交叉布置的交叉点。本发明可以实现对空气-空气换热设备的热工性能检测。
The invention discloses a detection apparatus for thermal performance of air duct type gas-gas heat exchange equipment. The detection apparatus is characterized in that: a first air duct and a second air duct are arranged respectively; the first air duct and the second air duct are arranged to be horizontally intersected, and the first air duct and the second air duct have a same structure that a heating section, a steady flow section, a test section, a test piece, a square and round transition section and a fan are sequentially arranged in series connection with the inlet of the air duct as a starting point so as to form an air flow passage; cross section of the part of air flow passage between the air duct inlet and the square and round transition section is rectangular; the test piece is an intersecting point for the intersecting arrangement of the first air duct and the second air duct. The invention enables detection of thermal performance of air-air heat exchange equipment to be realized.
