The high-temperature material heat exchange of pipeline, and driving heat source is used as in the generator and evaporator, the high-temperature material is changed into low temperature
Material；
The low temperature process into process water pipeline is absorbed heat in the absorber and condenser with water, be changed into high temperature work
Skill water.
6. method according to claim 5, wherein, the big temperature difference source pump also includes heat exchanger, and methods described also includes：
Heating agent water lines and process water pipeline is set also to be each passed through the heat exchanger so that into the low temperature of process water pipeline
Process water is divided into two-way, all the way into the absorber and condenser, all the way into the heat exchanger, and causes the heating agent
Water and the low temperature process are exchanged heat with water in the heat exchanger.
7. method according to claim 5, wherein, the temperature of the high-temperature material is 120-140 DEG C, the temperature of the low-temperature material
To spend for 30-50 DEG C, the low temperature process is 25-45 DEG C with the temperature of water, and the high-temperature technology is 65-85 DEG C with the temperature of water,
The heat medium water circulates between 20-40 DEG C and 100-120 DEG C.
8. method according to claim 7, wherein, the temperature of the high-temperature material is 125-135 DEG C, the temperature of the low-temperature material
To spend for 35-45 DEG C, the low temperature process is 30-40 DEG C with the temperature of water, and the high-temperature technology is 70-80 DEG C with the temperature of water,
The heat medium water circulates between 25-35 DEG C and 105-115 DEG C.
