What are the advantages and disadvantages of coal to electricity, heating, air source heat pump and regenerative electric heater?

Advantages: the heat pump has remarkable energy-saving effect, reduces coal pollution in winter and improves air quality.

Disadvantages: the cost is too high.

Step 2 heat up

Advantages: fast heat dissipation and high efficiency.

Disadvantages: it is not hot locally and takes up space.

3. Air source heat pump

Advantages: it does not occupy the effective use area of the building and has no pollution to the environment.

Disadvantages: In places with low outdoor temperature in the north, heat pump heating is insufficient in winter, and auxiliary heaters are needed. The reliability of air source heat pump in cold area is poor.

4. Regenerative electric heater

Advantages: It only needs to be electrified for 6-8 hours every day, so that heating can be realized 24 hours a day, thus achieving the purpose of saving heating costs.

Disadvantages: High surface temperature makes indoor air dry. If it is used improperly, it will make people breathe poorly and have a fever all over the body, which will have a bad impact on health. Such as damage to the skin.

Extended data:

Characteristics of air energy heat pump;

(1) The air source heat pump system integrates cold and heat sources, and there is no need to set up a special refrigeration room and boiler room. The unit can be placed on the roof or ground at will, without occupying the effective use area of the building, and the construction and installation are very simple.

(2) The air source heat pump system has no cooling water system, so it does not consume cooling water, and the cooling water system does not consume electricity. In addition, there are many reports of Legionella infection caused by cooling water pollution. From the point of view of safety and hygiene, air source heat pump also has obvious advantages.

(3) The air source heat pump system needs no boiler, corresponding boiler fuel supply system, dust removal system and flue gas exhaust system, which is safe and reliable, and has no pollution to the environment.

(4) The air source heat pump cold (hot) water unit adopts modular design, and there is no need to set up a standby unit. In the process of operation, the computer automatically controls and adjusts the running state of the unit to adapt the output power to the working environment.

(5) The performance of air source heat pump will change with the change of outdoor climate.

(6) In the area with low outdoor temperature in northern China, auxiliary heaters are needed because of insufficient heat pump heating in winter.
