Distributed cooling, heating and power combined supply system

Abstract

The embodiment of the invention discloses a distributed cooling, heating and power combined supply system, and relates to the technical field of energy treatment. The system comprises a gas turbine power generator set, a gas internal combustion engine power generator set, an ORC equipment power generator set, a slot type solar heat collecting field, an absorption type refrigerator, a multipurpose heat exchanger, a first heat exchanger, a second heat exchanger, a third heat exchanger and a plurality of valves. A high-temperature energy storage system, a low-temperature energy storage system, a gas boiler and a compression type refrigerator are further included. A gas turbine and a gas internal combustion engine are combined, the gas turbine continuously runs to be responsible for providing basic power loads, and the gas internal combustion engine serves as a peak regulating unit. By means of the distributed cooling, heating and power combined supply system, fuel consumption can be reduced, gradient utilization of the energy is achieved, and reliability and energy saving performance of the distributed cooling, heating and power combined supply system are further improved. Gas turbine inflow air is cooled in summer, and the generating capacity of the gas turbine is improved; and gas turbine inflow air is heated in winter, and accordingly the phenomenon of ice blockage of an air inlet system is reduced.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of energy processing, and in particular to a distributed combined cooling, heating and power supply system. Background technique [0002] The combined cooling, heating and power system is developed on the basis of combined heating and power, and it is the main direction and form of distributed energy development. The distributed energy system is relative to the traditional centralized energy supply energy system. The traditional centralized energy supply system adopts large-capacity equipment for centralized production, and then transmits various energies to a wide range of energy sources through special transmission facilities. Many users; and the distributed energy system has flexible layout and various structures. It produces and provides energy to users on the spot according to the needs of users. It can efficiently realize the comprehensive cascade utilization of energy and achieve...
