Advantages
1, energy saving
Undoubtedly, the biggest advantage of air water heater is energy saving. The low-temperature heat energy in the air is converted into high-temperature heat energy through the compressor, with the same amount of hot water manufacturing as the benchmark, compared with the electric heater water heater, maximize the savings of electricity, the use of the cost of only 1/4 of the electric water heater, and compared with the traditional gas water heater, do not have to use any gas fuel, the use of the cost of gas water heater is only 1/3 of the air as the main body, energy saving, not only can save people's The air as the main body, saving energy, not only can save people's cost of use, but also comply with the main body of the world's energy saving, which is one of the biggest highlights of the air water heater.
2. Convenience
The selling point of the air water heater is air, and one of the most basic needs of people for household goods is ease of use, so convenience has become the second major highlight of the air water heater. Because the amount of air is not affected by indoor and outdoor, sunny and cloudy days, compared with solar water heaters, air water heaters are very convenient, whether they are installed indoors or outdoors, moreover, regardless of cloudy and sunny days, the temperature is above zero degrees Celsius, can be used. In addition, after using up a tank of water, the air water heater only needs no more than an hour to create another tank of hot water, which can be used by the family around the clock.
3, safety
Electric water heaters exist in the leakage of security risks, gas water heaters exist in the worry of gas poisoning, and the two water heaters, compared to air water heaters through the medium of heat transfer, avoiding direct contact between the electric heating element and the water, which solves the leakage of electric water heaters exist in the hidden danger, and secondly, because the raw material is the air, and therefore also ruled out the gas water heater! Gas explosion or the possibility of gas poisoning, so that people use more comfortable and worry-free.
4, environmental
Energy saving and environmental protection are complementary, and environmental protection is the air water heater in the energy-saving advantage of another plus point. First of all, the air water heater utilizes electrical energy to compress air to create heat, without emitting exhaust and toxic gases, which is not only safe, but also creates a pollution-free bathing environment. Secondly, the air water heater can be used for up to 15-20 years, high life expectancy not only reduces the cost and trouble of replacing the water heater, but in a sense reduces the amount of waste produced, which is also an important aspect of environmental protection.
Air energy water heater as a new technology products, in the many varieties of water heater market stand out. In people's energy saving and environmental protection consciousness and consumer awareness is getting higher and higher today, I believe that the air water heater with high efficiency, convenience, safety, environmental protection advantages will be able to bring a new face to the water heater market!
Disadvantages
1, environmental adaptability
The source of heat of the air water heater is the air we must have, and as an energy-saving products, the degree of energy saving is closely related to the COP value of energy efficiency ratio. As most of the air water heaters on the market today are designed to operate at a normal temperature of 0-40 degrees Celsius, air water heaters tend to perform well in the south where the ambient temperature is relatively high.
And in winter temperatures of only -10 ℃ in northern cities, air water heaters are difficult to achieve the design of the expected results. If the temperature is -20 ℃ unit can not even start. Basically, only electric heating in winter (large electric kettle, and the temperature is low will be automatically heated)
2, air water heater installation problems
Domestic air water heaters often need a tank to heat and store hot water. For example, a family of 3-5 people needs a 120L-150L tank. Such a large size tank is not easy to coordinate with the overall home, so consumers can only install the air water heater on the balcony. But with the improvement of people's home environment requirements, the balcony of this big guy consumers are not willing to accept.
3, the degree of consumer awareness of the heat pump water heater
Heat pump water heater in the domestic market is a new thing, the degree of consumer awareness of it is still very low. There are a lot of people think that with a share of heat can get three shares of heat is impossible to achieve, and other products about the application of heat extraction technology is the same, although the popularity of heat pump air conditioner has been very high. People's awareness is limited only to the air conditioner is a big consumer of electricity, but do not know that it is more energy-efficient than burning briquette stoves. Today, because some of the larger shopping malls do not yet have air water heaters for sale, so consumer awareness of air water heaters is still very low.
4, the purchase cost is very high
An air water heater can buy a lot of gas water heaters. Although a little energy saving, but this cost can be used to pay the electricity or gas bill for a good seven or eight years.
With the development of the Industrial Revolution, in the early 19th century, there was a strong interest in the question of whether heat could be "pumped" from a medium of lower temperature to a medium of higher temperature. British physicist J.P. Joule proposed "by changing the pressure of the compressible fluid can make its temperature change" principle.
In the development of heat pump technology to date, there are also newer electromagnetic energy water heater technology, to a large extent, to improve the heat pump water heater due to low temperature and can not be used properly, greatly improving the full use of electricity. The phenomenon of hot water interruption during bathing has been alleviated.
Extended information:
Air energy water heaters, also known as air energy water heaters, are used to heat water from the atmosphere. p>Air energy water heater, also known as "air source heat pump water heater". "Air water heater" to the air in the low-temperature heat absorption, through the fluorine medium gasification, and then through the compressor compression pressure heating, and then through the heat exchanger into the water heating, compressed high temperature heat energy to heat the water temperature.
The air water heater is characterized by high efficiency and energy saving, making the same amount of hot water, is generally 4-6 times the electric water heater, its average annual thermal efficiency ratio is 4 times that of electric heating, the use of high energy efficiency.
The new product overcomes the shortcomings of solar water heaters that rely on sunlight for heat and inconvenient installation. Because the air water heater works through the medium of heat transfer, so it does not require electric heating element and water direct contact, to avoid the danger of electric water heater leakage, but also to prevent the gas water heater is likely to explode and the risk of poisoning, and more effective control of gas water heater exhaust emissions caused by air pollution.
Air water heaters don't need sunlight, so they can be placed at home or outdoors. Solar water heater storage water is used up, it is difficult to immediately produce hot water, if the electric heating and need a long time, while the air can be hot water at minus 20 degrees Celsius or more, you can 24 hours a day pressure operation. In this way, that is, after using a tank of water, an hour or so air water heater or even shorter time will produce another tank of hot water. At the same time it can also fundamentally eliminate the electric water heater leakage, dry burning and gas water heater use of harmful gases and other safety hazards,
Air-source heat pump water heater as the name suggests is the heat in the air through the refrigerant transported to the water, the traditional electric water heater and gas water heater is through the consumption of gas and electricity to obtain heat, while the air water heater is through the absorption of heat in the air to achieve the purpose of heating water. The purpose of heating water, in the case of consuming the same electrical energy can absorb heat energy equivalent to about three times the electrical energy to heat water.
Features
1, there is no restriction on installation conditions.
2, the use of safety, because there is no electrical components in direct contact with the water, so there is no danger of leakage.
3, energy saving and power saving, its power consumption is only 1/4 of the ordinary electric water heater, 1/3 of the gas water heater and 1/2 of the solar water heater.
