How about air heating? What are the advantages of air heating?

There are only three real advantages of low temperature air energy heat pump: 1. Energy saving; 2. Environmental protection; 3. It can be used in areas above -35℃.

First of all, talk about this energy saving.

The low-temperature liquid refrigerant in the low-temperature air energy heat pump can absorb a large amount of low-temperature heat in the air and vaporize it, which is compressed by the system compressor to form high-temperature and high-pressure refrigerant vapor. These vapors exchange heat with water in the heat exchanger, then the water is heated to raise the temperature, and the refrigerant is condensed to form a low-temperature gas-liquid mixture, which enters the next cycle.

Because the system will absorb the heat in the air and then convert it into mechanical energy, the thermal efficiency is high. Normal temperature air energy heat pump

Generally, it can reach more than 400%, while the thermal efficiency of low-temperature air energy heat pump can reach between 230% and 350% due to the influence of low-temperature weather. The higher the temperature, the higher the thermal efficiency.

The thermal efficiency will not exceed100% if electric heating is used directly; Gas wall-hung boiler

Burning natural gas, the thermal efficiency will not exceed 100%. From the point of view of thermal efficiency, low-temperature air energy heat pump kills electric boilers and wall-hung boilers, as well as the actual heating cost.

Liaoning 100㎡ family, the insulation effect is ok. The heating cost of low-temperature air energy heat pump is nearly one-third lower than that of electric boiler and half faster than that of wall-hung boiler.

Secondly, the low-temperature air energy heat pump is green and environmentally friendly.

This is an important reason for the rapid development of low temperature air energy heat pump in the north. As we all know, coal-fired heating is vigorously eliminated in the north because of air pollution control. Under the background of changing coal into electricity, air energy heat pump, biomass energy, solar energy, geothermal energy and other clean energy equipment have been popularized and applied.

Solar energy has low operating cost, harsh use conditions and high investment and maintenance costs; Biomass boiler is unsafe and has certain operating conditions; Geothermal needs drilling. Can you imagine the feeling of the city being overhead after more than ten years? And the cost after an operation is very high; Let's talk about low-temperature air energy heat pump first. It can be installed in one place, and there is no need to dig and bury pipelines in a large area to build a boiler room. Simple installation, safe use and the highest overall feasibility.

Finally, it is also the essential difference from air conditioning: low temperature resistance.

Friends who have learned about the heating principles of air conditioning and air energy heat pump will find that the two principles are actually the same, so why is air energy heat pump better? The key lies in low temperature resistance and more power saving. Low temperature air energy heat pump adopts enhanced steam injection technology.

Yes, now it can adapt to the environment of -35℃ However, due to different implementation standards, air conditioning focuses on refrigeration, and the heating capacity is not as good as air energy heat pump. When the temperature is low, the air conditioner needs electricity for heating, which consumes a lot of electricity and cannot be used by ordinary families.

Of course, you may have something to say. Since low-temperature air can have so many benefits, who still uses air conditioners, electric boilers and wall-hung boilers? Everything has two sides, and it is conditional for low-temperature air energy heat pump to save electricity.

First of all, the thermal efficiency will decrease with the decrease of temperature. The energy-saving effect is not obvious in the environment below 25℃ and above -30℃; The energy-saving effect is not good in the environment below -30℃ and above -35℃; It can't work normally below -35℃.

Therefore, it can't be used in areas below -35℃ in the north. It is not recommended to use in the area of -35℃~-30℃ without electrical assistance. If the temperature is higher than -25℃ in winter, then the low-temperature air energy heat pump exists for you.

Second, the larger the area, the more obvious the energy-saving effect of using air energy heat pump. Generally speaking, if the heating area is less than 60m2, it is not recommended. If you want to use it, you can consider the air energy heat pump hot air blower.

. Not because of the performance of the unit, but because of the equipment cost. The price of an air energy heat pump is not low, and it is unrealistic to pay the electricity bill by saving energy. Except those who have money to spend at home. Like large commercial enterprises, the energy-saving effect is very prominent. Some low-temperature air energy products can even be sold for more than ten yuan a square meter.

Third, the price of low-temperature air energy heat pump is usually more expensive than electric boiler and wall-hung boiler, which is also an important reason for air energy saving, but many people are still unwilling to use it.
