Description

technical field [0001] The invention relates to a solar secondary source heat source tower heat pump integration device, in particular to a solar secondary source heat source tower heat pump suitable for household type regional air conditioners used in summer "high temperature and high humidity" and winter "low temperature and high humidity" climate environments Integrated device. Background technique [0002] Southern China is located in the subtropical monsoon climate zone. In winter, the cold air from the north moves south and merges with the warm and humid air, making the vast area in the south a confrontation zone of cold and warm air. It is precisely because of this special climatic condition that the humid air contains infinite low-temperature potential energy of secondary sources converted from solar energy. The latent heat energy content is high in the humid air state. Since the traditional air source heat pump air conditioner continues to use the large temperature...

AI Technical Summary

Problems solved by technology

The latent heat energy content is high in the humid air state. Since the traditional air source heat pump air conditioner continues to use the large temperature difference heat transfer technology in the air conditioning industry, in low temperature and high humidity climates, the evaporation temperature is low, resulting in premature frosting and unable to operate normally for heating. Directly using electric heating for heating, high energy consumption has become a technical problem that has been difficult to solve for decades, and the humid heat in the air has become a harmful renewable energy source for air source heat pumps

[0003] At present, foreign countries have developed a device that uses a large temperature difference open cooling tower + salt solution + reverse osmosis membrane to directly aerate and circulate to absorb low-temperature heat sources in the air. The concentrated concentration of the salt solution causes the salt solution to absorb the condensed moisture in the air, and the reverse osmosis membrane cannot be used to effectively separate the moisture in the solution, and the discharge pollutes the environment, and the solution loss is large

Using the salt solution aeration cycle to absorb the low-temperature heat source in the air, another fatal problem is that the dissolved oxygen in the salt solution increases, which seriously corrodes the equipment, and the mist phenomenon of the open cooling tower is very serious. The steel structure is also severely corroded
