The present invention is a combined cooling, heating and power supply system with compressed air as an energy source. The characteristics of the vortex tube are used to divide the compressed air into two fluids, cold and hot. According to the principle, the heat of the thermal fluid is rationally utilized through the heat exchanger to output electrical energy and thermal energy. At the same time, the heat released by the interstage cooler in the process of compressing air is also utilized to maximize the utilization of the energy of the entire system. For different heating, cooling and power supply requirements, the performance of the system can be adjusted by adjusting the pressure regulating valve, the valve at the hot gas end of the vortex tube, and the water flow rate. The invention has high energy utilization rate, not only can effectively utilize the low-grade heat energy generated in each stage of the system, but also does not need to consume additional fossil energy in the whole working process, only compressed air is used as the energy source, and the cold, heat and electricity are realized. Combined supply, the system operates efficiently and saves energy and reduces emissions.
Description
technical field [0001] The invention belongs to the technical field of energy, relates to energy cascade utilization in the fields of compressed air, vortex tube refrigeration and combined cooling, heating and power (CCHP), and particularly relates to a combined cooling, heating and power supply system and method using compressed air as an energy source. Background technique [0002] As an "energy multimedia" that can convert, store and use various forms of energy, compressed air has the advantages of high safety factor and low environmental pollution. Therefore, compressed air as an energy storage medium is a very important medium with huge economic benefits. benefits and social benefits. However, most of the current energy storage systems for the application of compressed air are to heat the compressed air first (whether it is the combustion chamber or the waste heat of the exhaust gas from the turbine outlet), and then enter the expander to do work, which will cause the c...
