Problems solved by technology

The existing methods of utilizing industrial waste heat and waste heat are almost all simply using thermoelectric technology to generate electricity for evaporative cooling air-conditioning equipment, but the utilization rate of waste heat in hot water after heat exchange is generally low, because the final hot water The temperature is not high, and part of the heat will be lost in the process of transportation, so it is difficult to meet the needs of civilian use

In addition, the circulating cooling water in the evaporative cooling air-conditioning equipment adopts normal temperature water, and the heat dissipation effect on the air-conditioning equipment is not obvious in the actual evaporative cooling process, which in turn leads to a high operating load of the air-conditioning equipment and accelerates the power consumption of the air-conditioning equipment during operation.
