Description

technical field [0001] The invention belongs to the technical field of cooling and dehumidification in high-temperature mines and utilization of deep geothermal energy, and in particular relates to a high-temperature mine cooling and heat source utilization system based on an absorption heat pump and an operating mode. Background technique [0002] With the increase of mining depth and the improvement of mining mechanization, the problem of heat damage in deep mining mines has become more and more serious, and has become one of the main technical problems restricting mine production efficiency. Especially in the mining face, the temperature is high, the humidity is high, and the working environment of the mine is extremely harsh. This not only affects the production safety of mining enterprises and reduces the work efficiency of operators, but also endangers the physical and mental health and life safety of employees. At present, there are many problems in the cooling syste...
