Solar energy and biological energy complementary cogeneration cooling heating system

Abstract

The invention provides a cold-heat cogeneration system in which the solar energy and the biomass energy are complemented. The cold-heat cogeneration system is characterized by comprising a solar energy heat collecting box 1 which is communicated with a hot water storage box 2, wherein the hot water storage box 2 is communicated with a high temperature fermentation apparatus 3 which is communicated with a medium temperature fermentation apparatus 4; the medium temperature fermentation apparatus 4 is communicated with a normal temperature fermentation apparatus 5; the high temperature fermentation apparatus 3, the medium temperature fermentation apparatus 4 and the normal temperature fermentation apparatus 5 are communicated with a compressing apparatus 6 and are connected with a circulating water pump 14 which is connected with the solar energy heat collecting box 1; the compressing apparatus 6 is connected with a refrigerating device which is communicated with a purifying device 11, the purifying device 11 is connected with a generating device which is connected with the refrigerating device, and a turbo pressurized cooler 9 and a cooler 10 for a cylinder sleeve arranged at the lower part of the generating device are connected with a heat exchanger 12 and the hot water storage box 2. The cold-heat cogeneration system has the advantages of high energy utilization rate, low cost and good economical efficiency.

Description

Technical field: [0001] The invention relates to the technical field of utilization of renewable energy such as solar thermal energy and biomass energy, in particular to a combined cooling, heating and power generation system in which solar thermal energy and biomass energy complement each other. Background technique: [0002] In recent years, as one of the important directions of the world's second-generation energy technology development, the cogeneration system of cooling, heating and power has received extensive attention worldwide. The cogeneration system of cooling, heating and power is an advanced energy consumption method, which is a comprehensive production capacity and energy distribution system for cascade utilization according to energy quality. Distributed energy systems must follow the principle of scientific energy use (scientific use of energy, scientific allocation of energy and scientific management of energy), adopt various advanced technologies, and optim...
