Advantages
1. Energy saving
Undoubtedly, the biggest advantage of air energy water heaters is energy saving. The low-temperature heat energy in the air is converted into high-temperature heat energy through the compressor. Based on the same hot water production, compared with the electric heater, the electric energy is saved to the maximum, and the use cost is only 1/4 of that of the electric water heater. Compared with the traditional gas water heater, it does not consume any gas fuel, and the use cost is only 1/3 of that of the gas water heater. Taking air as the main body and saving energy can not only save people's use cost, but also conform to the main body of energy saving in the world, which is one of the biggest highlights of air energy water heaters.
2. Convenience
The selling point of air energy water heaters is air, and for household items, one of people's most basic needs is convenience, so convenience has become the second bright spot of air energy water heaters. Because the amount of air is not affected by indoor and outdoor, sunny and cloudy days, compared with solar water heaters, air energy water heaters are very convenient, and can be used whether they are installed indoors or outdoors, and whether the temperature is above zero degrees Celsius on cloudy and sunny days. In addition, after using up a box of water, the air energy water heater can make another box of hot water in less than one hour, which can be used by a family all day.
3. Safety
Electric water heaters have the potential safety hazard of electric leakage, while gas water heaters have the worry of gas poisoning. Compared with these two kinds of water heaters, air energy water heaters avoid direct contact between electric heating elements and water through medium heat exchange, thus solving the potential leakage hazard of electric water heaters. Secondly, because the raw material is air, it also eliminates the possibility of gas explosion or gas poisoning of gas water heaters, making people more comfortable and worry-free.
4. Environmental protection
Energy conservation and environmental protection complement each other, and environmental protection is another plus point in the energy-saving advantage of air energy water heaters. First of all, the air energy water heater uses electric energy to compress air to produce heat energy, and does not emit waste gas and toxic gas, which is not only safe, but also creates a pollution-free bathing environment. Secondly, the service life of air energy water heaters is as long as 15-2 years. Long service life can not only reduce the cost and trouble of replacing water heaters, but also reduce the waste production in a sense, which is also an important aspect of environmental protection.
As a new technology product, air energy water heater stands out in the water heater market with many varieties. Today, people's awareness of energy conservation and environmental protection and consumers' awareness are getting higher and higher. I believe that air energy water heaters will definitely bring a new look to the water heater market with their advantages of high efficiency, convenience, safety and environmental protection!
Disadvantages
1. Environmental adaptability
The heat source of air energy water heater is the air we all need, and as an energy-saving product, its energy-saving degree is closely related to the COP value energy efficiency ratio. Because most air energy water heaters on the market today are designed to work at -4℃, air energy water heaters often perform well in the south where the ambient temperature is relatively high.
However, in the northern cities where the temperature is only -1℃ in winter, it is difficult for the air energy water heater to achieve the expected effect in the design. If the temperature is -2℃, the unit can't even start. Basically, it can only be electrically heated in winter (large electric kettle, and it will automatically heat when the temperature is low)
2. Installation of air energy water heaters
Domestic air energy water heaters often need a water tank to heat and store hot water. Take a family of 3-5 people as an example and need a water tank of 12L-15L. Such a large-sized water tank is not easy to coordinate with the whole home, so consumers can only install the air energy water heater on the balcony. However, with the improvement of people's requirements for home environment, this big guy on the balcony is unwilling to be accepted by consumers.
3. Consumer's awareness of heat pump water heater
Heat pump water heater is a new thing in the domestic market, and consumers' awareness of it is still very low. Many people think that it is impossible to get three copies of heat with one copy of heat, and the same is true for other products related to the application of thermal recovery technology, although the popularity of heat pump air conditioners is already very high. People's understanding is limited to the fact that air conditioners are big consumers of electricity, but they don't know that they are more energy-saving than briquette stoves. Nowadays, consumers' awareness of air energy water heaters is still very low because some large shopping malls have not yet sold air energy water heaters.
4. The purchase cost is very high
An air energy water heater can buy many gas water heaters. Although it is a little energy-saving, this cost can be used to pay electricity or gas bills for seven or eight years.
with the development of the industrial revolution, in the early 19th century, people became interested in whether heat could be "pumped" from a lower temperature medium to a higher temperature medium. The British physicist J.P.Joule put forward the principle that the temperature of a compressible fluid can be changed by changing its pressure.
with the development of heat pump technology today, there is a new technology of electromagnetic energy water heater, which greatly improves the shortcoming that the heat pump water heater can not be used normally because of the low temperature, and greatly improves the full use of electricity. Relieves the phenomenon of hot water interruption during bathing.
Extended information:
Air energy water heater, also known as "air source heat pump water heater". The "air energy water heater" absorbs the low-temperature heat in the air, gasifies it by fluorine medium, then pressurizes and heats it by compressor, and then converts it into water heating by heat exchanger, and the compressed high-temperature heat energy is used to heat the water temperature.
The air energy water heater has the characteristics of high efficiency and energy saving. It produces the same amount of hot water, which is 4-6 times that of ordinary electric water heaters, and its annual average thermal efficiency ratio is 4 times that of electric heating, so it has high utilization efficiency.
this new product overcomes the disadvantage that the solar water heater relies on sunlight to collect heat and is inconvenient to install. As the work of air energy water heater is to exchange heat through medium, it does not need direct contact between electric heating elements and water, thus avoiding the danger of electric leakage of electric water heater, preventing the danger of explosion and poisoning of gas water heater, and more effectively controlling the air pollution caused by exhaust gas discharged by gas water heater.
the air energy water heater does not need sunlight, so it can be placed at home or outdoors. After the water stored in the solar water heater is used up, it is difficult to generate hot water immediately. If the electric heating takes a long time, and the air can heat water above MINUS 2 degrees Celsius, it can operate under pressure 24 hours a day. In this way, even if a box of water is used up, the air energy water heater will generate another box of hot water in an hour or so or even less. At the same time, it can also fundamentally eliminate the potential safety hazards such as electric water heater leakage, dry burning and harmful gas generated when gas water heater is used.
Air source heat pump water heater, as its name implies, transports the heat in the air to water. Traditional electric water heaters and gas water heaters obtain heat energy by consuming gas and electric energy, while air energy water heaters achieve the purpose of heating water by absorbing the heat in the air, which can absorb heat energy equivalent to about three times of electric energy when consuming the same electric energy.
Features
