Description

technical field [0001] The invention relates to an absorption heat storage system, in particular to a dual-pressure absorption heat storage system and a control method thereof. Background technique [0002] Energy shortage and environmental pollution are two major problems plaguing today's society, and the use of environmentally friendly and renewable energy sources such as solar energy, wind energy, tidal energy and geothermal energy can effectively solve these two problems. As one of these renewable energy sources, solar energy has been a hot research direction in recent decades. Among them, the main technologies of solar thermal utilization include solar thermal power generation based on solar energy efficient heat collection, solar thermal driven refrigeration, solar thermal driven dehumidification, etc. However, solar thermal sources are affected by time and show strong instability. In order to solve the instability of solar thermal energy utilization and the mismatch ...
