Novel combined cooling, heating and power system utilizing internal combustion engine waste heat and working method thereof

Abstract

The invention discloses a novel combined cooling, heating and power system utilizing internal combustion engine waste heat and a working method thereof. According to the technical scheme, the exhaustgas of an internal combustion engine releases energy through a waste heat boiler HRG to drive an organic Rankine cycle power generation system to circularly generate electricity; except that the exhaust gas of the internal combustion engine releases the energy through the waste heat boiler HRG to drive the organic Rankine cycle power generation system to circularly generate electricity, the remaining energy is divided into two branches, namely, a first branch and a second branch; the first branch is used for driving an ammonia absorption type refrigeration sub-cycle system to carry out cycle refrigeration; and the second branch, the internal combustion engine cylinder sleeve water and the organic Rankine cycle power generation system provide heat for a heat supply system. The system has the advantages that the organic Rankine cycle, the ammonia water power cycle and the heat supply device are coupled and integrated so that the cycle acting amount, the refrigerating capacity and the heat supply quantity can be increased, and the efficiency of the combined system can be improved.

Description

technical field [0001] The invention relates to a new cooling, heating and power cogeneration system for utilizing waste heat of an internal combustion engine and a working method thereof. Background technique [0002] The energy industry is the basic industry for national economic development and an important material basis for human survival and development. In the rapid development of contemporary society, a large amount of fossil energy such as coal and oil is being consumed. However, fossil energy is non-renewable, and with the continuous increase of consumption, fossil energy has gradually become a scarce energy source, and the cost of developing and using fossil energy is skyrocketing. In the face of increasingly severe environmental and energy problems, the realization of full utilization of exhaust heat from internal combustion engines has attracted increasing attention. Among the unused heat of internal combustion engine fuel combustion, exhaust gas accounts for ...
