Due to the high density of urban buildings, if high-rise residential buildings use room-type air source heat pumps, they will affect each other and the heating effect will be poor; the volume ratio of rural residential buildings does not exceed 0.3, and air source heat pumps do not interfere with each other, which can achieve the best performance of heat pump heating.
Current situation of urban heating
In addition, my country's cities and towns have built a relatively complete centralized heating system, and about 40% of the heat sources use cogeneration heat sources. When the cogeneration heat source with better operation adopts the exergy sharing method to share the total amount of coal burned by electricity and heat, the coal consumption corresponding to its heat production is converted according to the average coal consumption of coal-fired units in the country, and its COP can reach 4~7, which is a more energy-saving heat source than air source heat pumps.
At the same time, cogeneration can also be transformed into a heat-electricity coordinated cogeneration with power peak-filling function by adding large-scale heat storage devices. More than 60% of coal-fired power plants in northern my country are still pure power plants. If these are transformed into cogeneration and power peak-shaving plants as winter heating sources for urban buildings, their energy saving and peak-shaving effects will be better than air source heat pumps.
Advantages of practical air source heat pumps in rural areas
The building density in rural areas is low, and the investment and operation costs of large-scale centralized heating pipelines are much higher than those in cities with highly concentrated building density. Therefore, decentralized air source heat pumps should be used as heat sources.
Using air source heat pumps to achieve "coal to electricity" in rural areas is the best choice. It can eliminate the serious pollution caused by the burning of scattered coal in local heating in winter and significantly reduce haze; it can improve the indoor comfort of farmers in winter, and the economic burden is lower than that of scattered coal heating; it can be used as a "virtual peak-shaving power plant" to achieve large-scale power peak-shaving and valley-filling through active energy regulation; it can significantly improve the power generation efficiency of coal-fired power plants and improve the current inefficient operation of high-efficiency power plants; it can eliminate the bottleneck of wind power and photovoltaic power generation access to the Internet and promote the development of renewable energy power.
The future of air source heat pumps in rural areas
The market capacity of air source heat pumps is large. There are 50 million farmers in the Yellow River Basin in northern my country, and there is a demand market for 100 to 150 million air source heat pumps. The power load in northern my country is 600 million kW, and the total peak-to-valley difference is less than 150 million kW. Rural air source heat pumps can basically solve the problem of power peak regulation in northern winter. The application prospects of air source heat pumps are broad and will be very promising.
