Problems solved by technology

Compared with the mature cogeneration system of heat, power and cooling in developed countries, there is still a certain gap in the coordination and matching of the output of the three energy sources of heat, power and cooling due to the constraints of the current power structure system in China.
At the same time, taking into account my country's national conditions and energy medium and long-term development planning goals, the above three combined heating, power and cooling systems that use coal or natural gas as input energy, the former is more serious to air pollution, while the latter has clean combustion and high efficiency advantages, but my country's natural gas resources are limited and energy utilization costs are relatively high
