Distributed combined cooling, heating and power supply system

Abstract

The invention provides a distributed combined cooling, heating and power supply system. The distributed combined cooling, heating and power supply system comprises a power output device, a generationdevice and a cooling and heating output device; the power output device outputs mechanical energy and high temperature flue gas through a power machine; the generation device is connected with the power output device and used for converting mechanical energy into electrical energy; the cooling and heating output device is connected with the power output device and generates cooling capacity and heating capacity by using the mechanical energy and the high temperature flue gas; and the output power of the generation device and the cooling and heating output device can be adjusted. Three different forms of loads including cooling, heating and power are provided to users by the generation device and the cooling and heating output device at the same time.

Description

technical field [0001] The present disclosure relates to the technical field of energy machinery, in particular to a combined cooling, heating and power supply system. Background technique [0002] The distributed energy system is a new type of energy supply system that is different from the traditional large-capacity, large-scale power grid centralized energy supply method. The most rapidly developing distributed energy system is the distributed cogeneration system of cooling, heating and power. It is a miniaturized, modularized energy system that is integrated and arranged close to the user end, and can coordinate and meet the user's cooling, heating, and electrical load requirements as a whole. Supply system, also known as triple supply system. The distributed energy supply system has flexible layout and various structures, which can efficiently realize the comprehensive cascade utilization of energy and achieve higher primary energy utilization efficiency, which can gen...

Problems solved by technology

[0004] However, in the process of realizing the present disclosure, the applicant found that when using variable host load regulation, the regulation performance of the joint supply system is also poor due to the poor efficiency of the host load variable working condition; The energy storage device increases the initial investment of the system. At the same time, the response time of the energy storage device is long, and the regulation of user load fluctuations is slow.
