Embodiment Construction

[0040] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is carried out on the premise of the technical solution of the present invention, and detailed implementation and specific operation process are given, but the protection scope of the present invention is not limited to the following embodiments.

[0041] This embodiment introduces the Organic Rankine Cycle (ORC) into the traditional distributed cogeneration system of cooling, heating and power. The technology changes the flow rate of the working medium in the ORC system, thereby changing the power generation of the ORC system and the heat recovered from the prime mover 92 .

[0042] The combined cooling, heating, power and organic Rankine cycle system (CCHP-ORC) proposed in this embodiment includes a gas turbine, a gas internal combustion engine and other prime movers 92, a waste heat recovery module 93, a heat exchanger 1, an ...

Abstract

The invention relates to a combined cooling heating-power cogeneration and organic Rankine cycle combined system. The combined system comprises a combined cooling heating-power cogeneration device andan organic Rankine cycle device connected with the combined cooling heating-power cogeneration device. The organic Rankine cycle device is further connected with a variable frequency control device.The variable frequency control device comprises a variable frequency control module and a motor which are connected mutually. The variable frequency control module is connected with a common frequencypower network. The motor is connected with the organic Rankine cycle device. Compared with the prior art, the combined system has the advantages of being dynamically adjustable in thermoelectricity output, high in energy utilization rate and control flexibility, low in operation cost and the like.

Description

technical field [0001] The invention relates to the field of distributed energy systems, in particular to a combined cooling, heating, power and organic Rankine cycle combined system. Background technique [0002] Combined Cooling, Heating and Power (CCHP) system is a common application form of distributed energy systems. It usually follows the principle of energy cascade utilization. On the basis of power generation, it can effectively use the waste heat of the system for heating or cooling, thereby improving the utilization rate of primary energy. . [0003] Organic Rankine Cycle (Organic Rankine Cycle, referred to as ORC) is a Rankine cycle with low-boiling point organic matter as the working medium, which consists of four parts: heat exchanger, expansion power machine, condenser and working medium pump; its main feature is that it can Low-grade waste heat power generation. The organic working medium absorbs heat from the waste heat flow in the heat exchanger to generat...
