Distributed energy waste heat utilization system and working method thereof

Abstract

The invention relates to a distributed energy waste heat utilization system and a working method thereof. A water-air heat exchanger is connected with a prime motor, the prime motor is connected withthe user side, a flue gas outlet of the prime motor is connected with a lithium bromide unit, a cylinder liner water outlet of the prime motor is connected with a first distributor, the first distributor is connected to a heat pump and the lithium bromide unit, the heat pump is connected to the user side, a flue gas outlet of the lithium bromide unit is connected with a flue gas-water heat exchanger, the flue gas-water heat exchanger is connected with the user side, the flue gas-water heat exchanger is also connected with a second distributor, and the second distributor is connected with the heat pump and the user side; and the lithium bromide unit is connected with the user side, the lithium bromide unit is also connected with a third distributor, the third distributor is connected to theuser side and the water-air heat exchanger, the third distributor is also connected to an electric refrigerator, and the electric refrigerator is connected to the user side. By means of the distributed energy waste heat utilization system and the working method, the distributed energy waste heat quality is effectively improved, and the problem about safety and economical efficiency reduction of aworking condition system in summer is solved.

Description

technical field [0001] The invention belongs to the field of energy, and in particular relates to a distributed energy waste heat utilization system and a working method thereof. Background technique [0002] As a cutting-edge technology for substantial energy saving, distributed energy is one of the four cutting-edge technologies in the energy field of scientific and technological development planning. It has the advantages of small size, high efficiency, cleanness, and closeness to users. important practical significance and far-reaching strategic significance. [0003] Distributed energy sources with gas internal combustion engines as the prime mover generally provide energy such as cooling, heating, and electricity for hospitals, hotels, commercial complexes, and office buildings, such as the Chinese patent No. 201720678899.1. The waste heat of internal combustion engines is mainly divided into flue gas waste heat and cylinder jacket water waste heat. The two parts of w...
