Developing process of an accurate and reliable experiment rig for air-conditioning heat-exchanger was introduced, which includes the function of the experiment rig parts and designing range of the parameter. The performance of different condenser through a number of experiments was studied. The influence of face velocity, condensing temperature and contact thermo-resistance on the quantity of heat-exchanger and the influence of air resistance on face velocity were analyzed. The experimental result can be used for practical production and improve the performance of heat-exchanger effectively.
