Project scale: The project has a heating area of 10000 square meters, 16 units, and an investment amount of about 1.5 million yuan at a time.

9. Annual operation and maintenance fee

When the ambient temperature is-20 ℃, the annual power consumption per unit of product is about 1400 degrees. In industrial electricity, it is 1 yuan/kWh, and the annual unit operating electricity fee is about 1400 yuan. There is no need for subsequent investment in raw materials, and water is recycled water, so the annual operating cost of raw materials and water is 0. Maintenance costs such as labor costs (wages), equipment depreciation, repair costs, and management fees are approximately 4000 yuan/year. Comprehensive calculation, the annual operating cost per unit product is about 5400 yuan.

Heating is used in winter and central air conditioning is used in summer, which can save operating costs for users 'heating and cooling systems to the greatest extent possible. 2. Long service life and low operating costs. Developed and produced according to the inverse Carnot principle, it uses the refrigerant in the pipeline to exchange heat with the air, and flows through the heat exchanger to heat cold water and cool hot water; the air source heat pump unit has been optimized and designed on this basis to achieve a higher energy efficiency ratio, which can still maintain an energy efficiency ratio of 3.6 when the ambient temperature is-15℃, and the heating capacity is increased by more than 26% compared with ordinary air conditioners. 3. It is not affected by ambient weather and is available all year round. Compared with solar energy, the use of Yuelongkong air source heat pump unit is not affected by ambient weather and can operate normally in rainy days to ensure normal use every day. 4. Environmentally friendly products without any pollution. The unit structure is advanced, safe and reliable, and there is no danger of pollution, explosion, poisoning, etc. It is a heating equipment that produces domestic hot water and commercial water, has small investment, has the lowest operating costs, and has the most obvious energy conservation.

13. Level of impact of obstacles on technology transfer

Financing difficulties: The initial investment in technological innovation R & D is large, and purchasing equipment and materials requires a large amount of working capital. The economic affordability of local residents is low: the initial investment in ultra-low temperature air source heat pump units is large (about 10,000 - 20,000). Local residents have low acceptance of this technology: residents know less about ultra-low temperature air source heat pump units and are more accustomed to traditional heating methods. *It is difficult to introduce HVAC talents.
