Description

technical field

[0001] The invention relates to the technical field of waste heat utilization, in particular to a solar water heating system in which waste heat in summer can be used for solution dehumidification. Background technique

[0002] The solar water heating system technology is very mature, with good reliability and performance, and has multiple benefits such as economy, energy saving, and environmental protection. However, there is a common problem in solar water heating systems, that is, the imbalance between the heat supply and heat demand of the system. Especially in summer, the heat supply of the system is often much greater than the heat demand. According to the measurement data, the temperature of the water produced by the solar water heating system in summer can generally reach 65°C, and it can exceed 70°C when the sunshine is particularly good, while the water temperature is generally only required to be around 40°C, and the per capita water consumption is...
