Abstract

The invention discloses a visualization experiment system and device for testing separation characteristics of condensation water and belongs to the technical field of air condition heat exchanger. The system includes a combined air condition system, a condensation water visible testing unit, an air flow measurement unit and a frozen water system. The combined air condition system is used for performing filtration and heat-wet treatment on air in an entrance and then sending the air to a sample machine testing segment so as to meet requirements of experiment conditions. The condensation water visible testing unit is used for utilizing an endoscope for photographing a separation process of condensation water on heat exchange fins of the sample machine testing segment and recording pressure, temperature and humidity of the sample machine testing segment before and after the separation process. The air flow measurement unit is used for utilizing a flow nozzle and an electric micromanometer for testing air flow in the testing experiment condition. The frozen water system is used for utilizing a circulating water pump for conveying frozen water in a constant low temperature water bath into the experiment sample machine so as to take way heat of the sample machine. According to the invention, visible testing and thermo-technical characteristic testing of the separation process of condensation water in a heat exchange channel can be realized conveniently.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning heat exchangers, and relates to a visual experiment system and a device for testing condensate precipitation characteristics. Test of its thermal properties. Background technique [0002] Finned tube heat exchangers are partition wall heat exchangers and are widely used in air conditioning, refrigeration and chemical industries. When the surface temperature of the fins of the finned tube heat exchanger is lower than the dew point temperature of the air flow through the heat exchanger, the moisture contained in the air will condense on the surface of the fins, and the condensed water will adhere to the fins. On the surface, this process is called the wetting process or wet condition. In the process of dehumidification, heat and mass are exchanged between the air and the surface of the fins at the same time, and the condensed water precipitated under wet conditions will adhere to the surf...
