New energy cold and heat system for distributed energy storage power system

Abstract

The invention discloses a new energy cold and heat system for a distributed energy storage power system. The new energy cold and heat system comprises a fan coil unit arranged in the distributed energy storage power system and used for adjusting the temperature of the distributed energy storage power system, an absorption refrigerating machine connected with the fan coil unit and used for providing a cold source for the fan coil unit, a cooling tower connected with the absorption refrigerating machine and used for providing cooling water for the absorption refrigerating machine, a solar heat collector connected with the fan coil unit and the absorption refrigerating machine and used for providing a heat source for the fan coil unit and the absorption refrigerating machine, a first flow controller and a second flow controller. A brand-new heat management manner for the distributed energy storage power system is provided; the problem about heat management of the distributed large-scale container type energy storage power system is solved; the temperature of the work environment of a lithium ion battery is guaranteed, and the life cycle of the lithium ion battery is prolonged; and theprotection level is increased.

Description

technical field [0001] The invention relates to the field of distributed energy storage power supply systems, in particular to a new energy cooling and heating system for distributed energy storage power supply systems. Background technique [0002] Based on the background of the national power reform and the substantial increase in the installed capacity of renewable energy power generation, energy storage technology will play an important role in the five major links of power generation, transmission, transformation, distribution, and use. Traditional electric energy storage methods include physical energy storage methods such as water pumping, air compression, and flywheels, which are widely used, but the project investment is large, the construction period is long, and environmental damage and other problems are not suitable for the storage of distributed energy generation. dispute. With the formation of my country's lithium-ion battery industry chain, large-scale appli...
