In recent days the temperature dropped, not to mention the small partners in the South, even the author is now trembling trembling typing, holding a hot water bottle in and we type typing exchange.
Why do not you say air conditioning? In the South, most of the empty energy only summer cooling function, and no heating function.And compared with the cooling function, the air conditioning heating function can be described as a lot of shortcomings:
1, air-conditioning work to adapt to the temperature is 40 degrees minus 5 degrees. In other words, when the outdoor temperature is too low, the outdoor unit is very easy to frost air-conditioning, air conditioning start takes more time to defrost the outdoor unit, This will not only consume more energy, but also reduce the air conditioning heating effect.
2, the air-conditioning outlet is generally in the upper part of the human body, the hot air against the person's head blowing, blowing air conditioning when people's head will feel very hot, but the body is most afraid of cold feet but often do not feel warm, this warm The method is not suitable for human physiological perception.In addition, air conditioning heating will reduce the humidity in the air, resulting in the evaporation of water on the surface of the human body to speed up, make the population dry and throat dry itchy, very uncomfortable.
3, the price reason to 1.5 hp air-conditioning, for example, do not open the electric auxiliary heat conditions, the general heating power is 1kw, heating 3000kw. In theory, is to consume 1kw of electricity, can produce 3kw of heat However, due to the above mentioned first point, it is impossible to achieve such a high heating efficiency when the air conditioner is heating in winter.
Compared with the air-conditioning, the advantages of air to heat pump heating is very obvious, the air heat pump can not heat to the end of warm or radiator, hot air is blowing from bottom to top, plus its heat transfer process is achieved through water Of the heating will not affect the reduction of air humidity, so the human body will feel a lot of comfort, comfort is much stronger than air-conditioning heating.
In terms of power consumption, the air heat pump mainly uses the heat in the air plus less energy to heat, heating power is 1KW, heating 4000KW, which consumes 1KW of electricity, can produce 4KW of heat, and is not subject to outdoor temperature According to Niuntai air can provide data, Beijing outdoor minus 20 degrees, the room temperature to 20 degrees, the monthly power consumption will not exceed 450 yuan, with the cost of coal, but more than air-conditioning consumption Less electricity.
Because of the advantages of air-to-heat pumps, air-to-air heat pumps have become the star equipment for coal-to-electricity in the northern coal-to-electricity conversion project in 2016 and have been vigorously promoted by the state.
