Multi-mode cooling, heating and power integrating system driven by waste heat

Abstract

The invention relates to a multi-mode cooling, heating and power integrating system driven by waste heat. The multi-mode cooling, heating and power integrating system driven by waste heat comprises ageneration mechanism, a separator, a shunt, an expansion machine, an electric generator, a heat supply mechanism, a condenser, a cooling mechanism, a regenerator, a first cylinder block and a second cylinder block. Compared with the prior art, the multi-mode cooling, heating and power integrating system driven by waste heat has the following beneficial effects that low-grade waste heat is utilizedeffectively, heat energy of waste heat sources, difficult to utilize, can be generally converted into the same-grade heat energy for heating and converted into higher-grade electric energy and cold energy to be used; a manual and automatic integrated electric three-way valve regulated by a control system can enable a working circuit to be switched among multiple modes of power-heat united supply,cold-heat united supply and cold-heat-power united supply; since common industrial waste heat has the characteristic of stable output, selective and continuous output of electric quantity, cooling capacity and quantity of heat of the system can be ensured; and a concentrated solution is transported from an absorber at a low-pressure end to a generator at a high-pressure end by a novel solution pumping structure comprising the absorber, a working chamber, a high-pressure cavity, a solenoid valve and a control system.

Description

technical field [0001] The invention relates to the fields of absorption technology, power generation technology and refrigeration and heating technology, and in particular to a multi-mode integrated cooling, heating and power system that can be driven by low-grade waste heat. Background technique [0002] Waste heat is the energy that is not used in energy utilization equipment under certain economic and technical conditions, that is, redundant and waste energy. According to the survey, the total waste heat resources of various industries account for about 17% to 67% of their total fuel consumption, and the recyclable waste heat resources are about 60% of the total waste heat resources. However, due to reasons such as enterprise production structure and industrial equipment configuration, A large number of waste heat resources in our country are still discharged directly. It can be seen that the effective and reasonable use of waste heat resources will be an important way ...
