Embodiment 1

[0053] see figure 2 , when the hybrid indirect cooling compressor experimental system of the present invention performs the linkage experimental test of the open and closed test sections, it is necessary to open the circuit switch valve 13 and close the deflation switch valve 11. The gas passes through the flow meter 4, flows into the compressor 6 under test in the open test section for pressurization, and then adjusts the pressure through the regulating valves 9 and 10, and lowers the temperature in the heat exchanger 12, and flows into the compressor under test in the closed test section 16 for pressurization, and finally through the regulating valves 18 and 19 to reduce the pressure and discharge it into the muffler 22 to complete the linkage experiment test. During the test, when the inlet pressure of the tested compressor 16 is on the low side, reduce the opening of the air release regulating valve 11, increase the opening of the air supply regulating valve 27 (the suppl...

Embodiment 2

[0055] see image 3 , when the experimental system of the hybrid indirect cooling compressor of the present invention performs the experimental test of the open test section, it is necessary to open the deflation on-off valve 11 and close the circuit on-off valve 13 . The gas passes through the flowmeter 4, flows into the compressor 6 under test in the open test section for pressurization, and then adjusts the pressure through the regulating valves 9 and 10, and finally discharges into the muffler 22 through the air release switch valve to complete the experimental test of the open test section . During the test, the air supply unit does not operate; the cooling unit chooses whether to use nozzle water spraying to cool down according to the exhaust temperature of the closed-type compressor 6 under test.

[0056] To sum up, the hybrid intercooled compressor experimental system proposed by the present invention can not only be applied to the experimental test of the intercooled...

Description

technical field [0001] The invention belongs to the technical field of compressed air energy storage, and relates to an experimental testing system suitable for a compressed air energy storage compression subsystem, in particular to a hybrid indirect cooling compressor experimental system. Background technique [0002] With the development of the economy, the society's demand for energy is gradually increasing, but what follows is the lack of energy and the low utilization rate. In order to optimize the energy structure and protect the environment, it is necessary to vigorously develop renewable energy such as wind energy and solar energy. However, there are many problems in the process of large-scale promotion and utilization of renewable energy, such as intermittency and volatility. In order to solve the above problems, electric energy storage technology can be used, and there are many electric energy storage technologies, among which compressed air energy storage is not l...
