Problems solved by technology

Since the exhaust steam at the tail of the steam turbine still has a certain working ability, reusing it can effectively improve the efficiency of the organic Rankine cycle, and the potential of solar energy resources is huge, which can convert the exhaust steam at the tail of the steam turbine that still has a certain working ability into secondary energy. However, since the use of solar energy resources is limited to the daytime, it is necessary to design a new type of organic Rankine cycle system with a new type of combined cooling, heating and power system with collection / storage capacity, which can be used more reasonably. of natural resources

Description

technical field [0001] The invention relates to the technical field of organic Rankine cycle, in particular to a novel combined cooling, heating and power generation system based on a movable solar heat collector. Background technique [0002] my country's rapid economic development has brought about energy shortages and serious environmental pollution. Among them, the utilization rate of natural energy such as geothermal energy and solar energy is low, while my country's geothermal resources are very rich, and solar energy resources are everywhere. Belonging to renewable resources, the rational use of natural resources has become an important way to alleviate energy problems. [0003] Organic Rankine Cycle (Organic Rankine Cycle, referred to as ORC) system is a Rankine cycle system with low boiling point organic matter as the working medium. It is mainly composed of waste heat boiler or heat exchanger, steam turbine, condenser and working medium pump. Its working The princi...
