| Abstract: | In order to study the evaporation and condensation mechanism of new refrigerants and single tube, a new test device with stable performance was designed and set up, which could be used in vaporing, condensing and falling film evaporation outside single tube/tubes. The device also could be used for evaluating the effects of refrigerant, mass flow and tube diameter. And the control system was established using Siemens PLC and Sunway Force Control Configuration Software, which could realize the data acquisition, automatic control and monitoring. The test efficiency could be improved significantly. At the same time, the verification of the condensation heat transfer outside plain tube was conducted. The results showed the reliability and rationality of the experiment device. |
