Absorption heat storage system using absorption refrigeration and control method thereof

Abstract

The invention provides an absorption type heat storing system cooled by adopting absorption type refrigerating. The absorption type heat storing system comprises an absorption type refrigerating sub circulating system and an absorption type heat storing sub circulating system. The absorption type refrigerating sub circulating system comprises a second evaporative condenser (6) and a second absorption generator (5). The absorption type heat storing sub circulating system comprises a first evaporative condenser (3), a connecting valve (2) and a first absorption generator (1). The invention further provides a control method of the absorption type heat storing system cooled by adopting absorption type refrigerating. The absorption type heat storing system cooled by adopting absorption type refrigerating and the control method of the heat storing system have the beneficial effects that the system reaches a large concentration slippage and a high energy storage density in the heat storing process; energy can be stably stored in a chemical energy form in the energy storing process, so that heat loss is avoided; and in the output process, heat quantity output and cold quantity output can be conducted according to needs. The absorption type heat storing system is used for storing solar heat energy and industrial waste heat, high in energy storing density, and long in storing period andhas a plurality of output modes.

Description

technical field [0001] The invention relates to an absorption heat storage system, in particular to an absorption heat storage system adopting absorption refrigeration cooling and a method thereof. Background technique [0002] The key issue of sustainable development in today's world is to effectively solve energy and environmental problems, and the use of clean and renewable energy is the only way for human development. As a clean and renewable energy source, the utilization of solar energy has become a hot research direction in recent years. The main technologies of solar thermal utilization include solar thermal power generation based on solar thermal sources, solar thermally driven refrigeration, and solar thermally driven dehumidification. However, solar heat sources are affected by weather, day and night, and seasons, showing strong instability and seasonal differences over time. for efficient storage. For example, for the mismatch between supply and demand of solar...

AI Technical Summary

Problems solved by technology

[0004] These two heat storage methods have serious heat dissipation during the energy storage process, and the longer the time is, the more serious the energy loss is, which is not suitable for long-term energy storage, nor can it solve the problem of long-term differences in solar energy utilization.
