Abstract

The invention discloses an ammonia water working medium combined cooling heating and power system utilizing a medium-low temperature heat source and a working method thereof, and belongs to the technical field of medium-low temperature heat source recycling and power engineering. Ammonia water is adopted as a cycle working medium, Kalina cycle, ammonia water absorption refrigeration cycle and ammonia water absorption heat pump cycle are organically integrated to form the novel ammonia water working medium combined cooling heating and power system for the medium-low temperature heat source, andelectric energy, cold energy and heat energy can be provided for users. The system has three operation modes of power generation, cold power and heat power, for example, the power generation mode canbe operated in spring and autumn, the cold power mode can be operated in summer, and the heat power mode can be operated in winter in China. The system meets the requirements of users for different types of energy, gradient utilization of energy is achieved, and the energy utilization efficiency of the medium-low temperature heat source is improved.

Description

Technical field [0001] The invention belongs to the technical field of medium and low temperature heat source recovery and utilization and power engineering, and specifically relates to a cold, heat and power cogeneration system using a medium and low temperature heat source as an ammonia working medium and a working method thereof. Background technique [0002] With the continuous growth of human demand for energy, large-scale burning of fossil energy has had a serious impact on the atmospheric environment and ecological environment, and people are increasingly worried about resource depletion and environmental pollution caused by the large-scale use of traditional fossil energy. Under such circumstances, the development and utilization of renewable energy and the recycling of industrial waste heat have attracted more and more attention from all over the world. The development and utilization of renewable energy and industrial waste heat plays a vital role in saving fossil energ...
