What does it mean to change residential coal to electricity?

1, coal to electricity means replacing traditional boilers with electricity as clean energy, that is, replacing boilers.

2. There are two ways to convert media into electric energy:

Replace ordinary coal-fired boilers with electric boilers;

The coal-fired boiler and the original HVAC system were all cut off, and heating facilities such as electric heating film or heating cable were replaced.

Advantages of air source heat pump:

According to the 20 16 Guiding Opinions on Promoting "Changing Coal into Clean Energy, Reducing Coal for Coal" issued by Beijing Agriculture Committee, it is clearly put forward that the selection of heat source equipment: in principle, the use of "direct heating" electric heating equipment is prohibited in all districts, and the use of "multi-energy linkage, multi-heat combination and multi-source integration" is encouraged.

Low temperature air source, etc. , which integrates various devices, should guide residents to use efficient air source heat pump (COP) in villages in plain areas. The promotion of heat pump and multi-energy linkage equipment in each district should not be less than 80% of the heating equipment in this district. Investigate its reason, mainly for two points:

The energy-saving effect of heat pump is remarkable:

1. Take an 80㎡ residential building in Beijing as an example. The heating days in Beijing are 120 days, and the heating load area index is 60W/㎡. If the heating time is 24 hours a day, the heating load (kW h) q = 8432.64. The COP of air source heat pump is calculated at a low level, taking 250%, and the power consumption in the whole heating season is 3373 degrees.

2. According to the special heating power consumption from 2 1 o to 6: 00 the next day, 0. 1 yuan/degree and 0.48 yuan/degree in daytime, the use cost is about 1 100 yuan, which is more than half of that of direct electric heating.
