From the view of the amount of human-averaged fossil energy resources, coal resources are only 60% of the world's average level, oil is only 10% of the world's average level, and natural gas is only 5%. From the perspective of energy production and consumption, China has become the second largest energy producing country and the second largest energy consuming country in the world at present, and environmental pollution caused by mass production and use of fossil energy is very serious.
A Combined Cooling, Heating and Power (CCHP) system is a system derived from a Combined Heat and Power (CHP) system, and the system is a Combined heat and Power system which is established on the basis of the concept of cascade utilization of energy and generates heat, electricity and cold by taking combustible gas (including natural gas, methane, blast furnace gas, coke oven gas and the like) as primary energy. The system utilizes equipment such as a small gas turbine, a gas internal combustion engine, a micro-combustion engine and the like to combust fuel to obtain high-temperature flue gas which is firstly used for power generation and then used for refrigeration and heating by utilizing waste heat; if the sulfur content of the fuel is very low, domestic hot water can be provided through the low-temperature flue gas heat exchanger, and exhaust energy is fully utilized. The energy utilization rate is improved to more than 80 percent, and a large amount of primary energy is saved. However, the cold, hot and electricity triple supply system needs three loads of cold, hot and electricity to be matched for operation, otherwise, the high-efficiency energy utilization rate cannot be achieved; the difference of the three loads of cold, heat and electricity in the area is large along with the difference of factors such as the area, the climate, the day and night, and the like, so that the three loads of cold, heat and electricity which are matched are not easy to obtain.
