Air-cooled heat exchange experimental device
This is a system commonly used in heating and cooling air conditioning equipment for buildings and houses, as well as radiators. It is a tabletop experimental device where heated hot water circulates through copper pipes in a heat exchanger and exchanges heat with the air flowing through a wind tunnel. The device comes with a 32-tube heat exchanger, and as an option (sold separately), 16-tube and 16-tube fin-type heat exchangers are available, allowing experiments to be conducted with either type of heat exchanger installed. The hot water system consists of a tank with a PID-controlled heater, a pump, and a water level gauge, and it digitally displays the inlet and outlet temperatures and flow rate of the hot water. The air supply duct system is made up of an orifice and pressure holes for flow measurement, an electric fan, and a slide valve, and it digitally displays the temperatures at the duct inlet and the inlet and outlet of the heat exchanger, as well as the differential pressure across the orifice. In the empty space on the right side of the device, an optional (sold separately) data automatic collection system (VDAS-F) can be installed. By using the data automatic collection system, various data can be collected in real-time to a PC (sold separately), allowing for the analysis of experimental results.
