5. Air resource heat pump running costs compare with other ways HUIHUANGSUN

6. Analysis and Conclution 1 、 Operating cost's investigation and analysis ： Inverstigation and analysise of operating cost for example: Air resource heat pump + low temp. rediant floor heating, the water Temp. is 30 ℃～ 40 ℃， The difference of temp. is 5 ℃ 。 In Beijing's winter, Daytime's energy efficiency rate(COP) can stabilize at 3.0 above ； Although Winter's outdoor is cold, and aravage energy efficiency is also lower than daytime, but we can use nighttime's preferential benefit from peak-valley electricity price ， User's actual heating costs are cheaper. The result of this survey: heating costs is 12~22/m 2 whitch is 50% ～ 75% of the central heating HUIHUANGSUN

7. Analysis and Conclution （ continue...... ） 2 、 The investigation and analysis of Initial investment costs (one time fee) ： — The electric boiler + radiator + storage electric heater and electric heating and so on are lower — The Secondary Air source heat pump for low temperature radiation heating system 。 — The highest is solar energy + assisted air-source heat pump floor heating HUIHUANGSUN

8. Analysis and Conclution （ continue...... ） 3 、 The investigation and analysis of public facilities capacity increase fees ( Capital Investment ) ： This fee is one of the largest investment in the government, not only need consideration of the initial investment cost but also to assess the efficiency of equipment use for year-round 。 — Air resource heat pump floor heating and heat pump heating with solar energy anxiliary are lower 。 — Wall - mounted gas boiler, storage-heating electric heating and electric floor heater and electric boilers are higher — The later's expense is 2-3 times of former 。 HUIHUANGSUN

9. Analysis and Conclution （ continue...... ） 4 、 Investigation and Analysis of the hot water temperature and room temperature fluctuation ( comfortability ) ： Society is in the development, heating comfortability is very important, which is the embodiment of Humanization 。 — The comfortability of Low Temperature ground radiation heating is the best ； — The radiator is the second ； — The storage electric heating is lower 。 HUIHUANGSUN

10. Analysis and Conclution （ continue...... ） 5 、 Investigation ans analysis of power consumption and energy efficiency rate (COP)(Energy saving) ： (COP) is an important index to evaluate the efficiency of energy-saving heating equipment, solar auxiliary air source heat pump floor heating heating system is the highest, The second is the air source heat pump heating system, The lower is electricity heating mode. But there are any disadvantages on solar heating system from before cases: 1 、 The maintenance of solar heating system is rather complicated, and maintenance cost is higher, non-proffesional people can't competency. 2 、 it can't heating in night and days without sunshine, it can work only under anxiliary energy. — Electric boiler anxiliary: electricity is too expensive. — Wll-mounted boiler anxiliary: Initial investment is higher, and it is the key whether there is enough gas 3 、 From the effect of energy saving and convenience of the comprehensive, air source heat pump heating is the best choice. 。 HUIHUANGSUN

11. Analysis and Conclution （ continue...... ） 6 、 Total cost of the whole process: （ Eight years ） is a comprehensive economic evaluation index 。 It is considering the initial investment in a project, and operating costs of a project, it is used scientific evaluation method in economically developed countries. This investigation taked evaluation to 6 kinds clean energy heating means of the whole process, they include equipment initial investment, infrastructure capacity fee and 8 years's operating expensive. — Air resource heat pump with anxilirary radiant floor heating system is the lowest ； — The higher is the electric boiler + radiator heating system / heat storage electric heating electric heater / etc. 。 — Wall mounted gas boiler is in the between of above 2 kinds 。 The air source heat pump heating is the first choice in cold area!
