The invention relates to a visual CO2 mixed working medium saturation state point test system, which comprises a working medium precooler, a working medium storage tank, an evaporator, a heat exchanger, a front-end precooler, a front-end condenser, a subcooler and a visual observer. The outlet end of the working medium precooler is connected to the inlet end of the working medium storage tank, the outlet end of the working medium storage tank is connected to the inlet end of the evaporator, the outlet end of the working medium precooler and the outlet end of the working medium storage tank are each provided with a pipeline sight glass, a visual precooling observer is arranged between the front-end precooler and the front-end condenser, and a visual condensation observer is arranged between the front-end condenser and the subcooler. Through the arrangement of the visual window, experimenters can visually observe the states of droplet generation and bubble disappearance in the phase change process of the working medium, the states are recorded through the high-speed camera, the accuracy of actually measured data can be effectively guaranteed, and the CO2 mixed working medium saturation state point testing system has important use value for a CO2 mixed working medium saturation state point testing experiment and is suitable for conversion application.
Description
technical field [0001] The invention belongs to the field of thermal equipment, relates to mixed working fluid measurement technology, especially a visual CO 2 Mixed working fluid saturation state point test system. Background technique [0002] With the increasingly prominent problem of energy shortage and the strengthening of environmental protection awareness, the attention, research and utilization of renewable energy by the whole society have been continuously strengthened. Geothermal power generation and ground source heat pump heating are the main ways to utilize geothermal resources at present. Selecting suitable working fluids for different grades of heat source conditions and utilization methods has become the focus of research, in order to maximize the use of geothermal resources, improve efficiency, and reduce losses. . [0003] In order to improve the efficiency of geothermal power generation and ground source heat pump systems and reduce the heat transfer los...
