In recent years, the competition between "traditional air conditioner" and "air source heat pump" has become more and more intense. Consumers are often confused and puzzled. Today, Leomon will give you a science lesson on air source heat pump.
1. Working principle
First, let's take a look at the principles of the two to understand how they work. Working principle of air source heat pump. Air source heat pump uses refrigerant as a medium. The vaporization temperature of refrigerant is low and it can be vaporized at -40℃. Therefore, there is a temperature difference between it and the outside temperature. The refrigerant absorbs the outside temperature and vaporizes. It is compressed and heated by the compressor to become a high-temperature and high-pressure gas. After exchanging heat with water through the heat exchanger, the pressure is released through the expansion valve and returns to the low-temperature and low-pressure liquefied state. Through the continuous circulation of the refrigerant and the exchange of heat with water, the water in the water tank is heated. Traditional air conditioners use Freon as a refrigerant. By adjusting the refrigerant flow rate with the refrigerant as the medium, the outdoor unit can transport refrigerant liquid to several indoor units through pipelines.
2. Stability
Secondly, observe the stability of the two. The process of the outdoor unit of the air source heat pump completing the refrigeration cycle is a complete system. The indoor unit is independent of the outdoor unit through heat exchange and does not affect each other, which makes its stability more prominent. However, the outdoor unit and indoor unit of the traditional air conditioner together constitute the refrigeration system. Once one unit fails, the entire system will be unbalanced. The traditional air conditioner is a ripple effect, and the performance is not as good as the stability of the air source heat pump.
3. Comfort
Again, in terms of comfort, the medium of the air source heat pump is water, and the wind blown out is softer, more peaceful, and less irritating to the body. The "traditional air conditioner" can make people who are heated outdoors feel a burst of coolness instantly, but the fusion temperature difference may cause discomfort such as colds, and it is also easy to get what is usually called air conditioning disease.
4. Environmental protection
There are also countries that attach importance to energy conservation and environmental protection, and advocate ecological harmony. Air source heat pumps do not use Freon refrigerants, and the indoor medium is water, which does not pollute the environment. In traditional air conditioners, the medium in the indoor pipes is refrigerant, which is the culprit of the greenhouse effect and will also damage the atmosphere. In terms of safety and environmental protection, it is very different from air source heat pumps and cannot be matched at all.
5. Energy saving
Finally, by comparing the energy saving of the two, let the facts speak for themselves. The cooling and heating temperatures of traditional air conditioners cannot be adjusted, that is, the input power will not change. There is only one condition, which is to shut down when the indoor set temperature is reached and to start when the indoor set temperature is not reached. In terms of energy consumption, the cost is naturally uncontrollable, while the temperature of air source heat pumps can be adjusted, and the flexibility is naturally much higher, and inverter output can be achieved. We must also be clear that air source heat pumps actually rely on heat pumps to start cooling, absorbing a large amount of free heat energy in the air for cooling or heating, which is very energy-saving and saves 75%. In the long run, the cost is lower than that of "traditional air conditioners" and is more cost-effective.
Air source heat pump wins the competition
Through the above comparison, it is obvious that "air source heat pump" is more in line with people's pursuit of healthy life and is also the call of the country for energy conservation and environmental protection. Looking at the current use of air conditioners, from hotels, villas, schools, hospitals to thousands of households, more and more customers choose air source heat pumps to cool down in summer and heat in winter. It is not only low-consumption and energy-saving, but also safer and more environmentally friendly.
