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 with fluorine medium, heats and pressurizes it after being compressed by the compressor, and then the water is converted into water for heating through the heat exchanger. 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 can produce the same amount of hot water, 4-6 times as much as the electric water heater, and its annual average heat efficiency ratio is 4 times as much as the electric heating, with high energy efficiency. So, what is the working principle of the air energy heat pump water heater? Next, I will tell you about the air energy heat pump water heater.

Working principle of air energy heat pump water heater

The air energy water heater works according to the principle of "inverse Carnot". Figuratively, the "outdoor unit" compresses the air like an air blower to raise the air temperature, and then transfers the heat to the indoor water storage tank through a liquid that will boil at - 17 ℃, and then transfers the heat to the water. To put it simply, it absorbs the heat in the air to heat the water temperature, and the heat absorbed air is used in the kitchen to solve the stuffy problem.

The principle of heat pump is used for heating, which is contrary to the refrigeration of air conditioner - the national refrigeration standard is 1000 watts, and the electric refrigeration standard is 2800 watts. According to the principle of heat balance, at least 2800 watts of heat will be generated at the same time. With the input of 1000 watts of electricity, the actual heat generated is 3000-4000 watts. When these heat are delivered to the insulated water tank, the power consumption is only a quarter of that of the electric water heater (even if the thermal efficiency of the electric water heater is 100%, the input of 1000 watts of electricity is only 1000 watts of heat).

Air energy water heaters do not need sunlight, so they 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 electric heating takes a long time, the air energy water heater can operate under pressure 24 hours a day as long as there is air and the temperature is above zero ℃. In this way, the air energy water heater will generate another tank of hot water in about an hour after using a tank of water. At the same time, it can also fundamentally eliminate the electric water heater leakage, dry burning, gas water heater use of harmful gases and other security risks, overcome the solar water heater can not be used in rainy days and inconvenient installation and other shortcomings, with high safety, high energy conservation, long life, no toxic gas emissions and many other advantages. The service life of air energy water heaters can generally reach 15 to 20 years.

Advantages and disadvantages of air energy heat pump water heater

1、 Advantages

1. Energy saving first

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 electric water heaters, it can save electricity to the greatest extent. The use cost is only 1/4 of that of electric water heaters, while compared with traditional gas water heaters, it does not consume any gas fuel, and the use cost is only 1/3 of that of gas water heaters. Taking air as the main body and saving energy can not only save people's use costs, but also conform to the main body of energy conservation in the world, which is one of the biggest highlights of air energy water heaters.

2. Easy to use

The selling point of air energy water heater is air. Air is everywhere and everywhere. For household products, one of the most basic needs is ease of use. Therefore, convenience has become the second highlight of air energy water heater. Because the amount of air is not affected by indoor and outdoor conditions, sunny days and cloudy days, compared with solar water heaters, air energy water heaters are very convenient. They can be easily used as long as there is air and the temperature is above zero degrees Celsius, no matter whether they are installed indoors or outdoors, or in cloudy days and sunny days. In addition, after using up a tank of water, the air energy water heater can produce another tank of hot water in less than an hour, which can be used by a family all day long.

3. Safe

The electric water heater has potential safety hazards of electric leakage, and the gas water heater has the danger of gas poisoning. Compared with the two types of water heaters, the air energy water heater exchanges heat through the medium to avoid direct contact between the electric heating element and water, which solves the potential electric leakage of the electric water heater. Secondly, because the raw material is air, it also eliminates the possibility of gas explosion or gas poisoning of the gas water heater, Let people use it more comfortably.

4. Environmental protection bonus

Energy conservation and environmental protection complement each other, and environmental protection is another point on the energy saving advantages of air energy water heaters. First of all, the air energy water heater uses air to produce heat energy, and does not discharge waste gas and toxic gases. It is not only safe, but also creates a pollution-free bathing environment. Secondly, the air energy water heater has been used for 15-20 years, and its long life can not only reduce the cost and trouble for people to replace the water heater, but also reduce garbage production in a sense, which is an important aspect of environmental protection.

As a new technology product, the air energy water heater stands out in the water heater market with many varieties. With people's increasing awareness of energy conservation and environmental protection and consumer awareness, I believe that the air energy water heater will bring a new look to the water heater market with its advantages of high efficiency, convenience, safety and environmental protection!

2、 Disadvantages

1. Environmental adaptability

The heat source of air energy water heater is the air that we all need. As an energy-saving product, its energy saving degree is closely related to COP value and energy efficiency ratio. Since most of the air energy water heaters on the market today are designed to operate normally at 0-40 ℃, air energy water heaters often perform well in the south where the ambient temperature is relatively high. However, in northern cities where the winter temperature is only - 10 ℃, it is difficult for air energy water heaters to achieve the desired effect. If the temperature is - 20 ℃, the unit cannot even be started.

2. Installation problems of air energy water heater

Domestic air energy water heaters often need a water tank to heat and store hot water. Take a family with 3-5 people as an example, 120L-150L water tank is required. Such a large water tank is not easy to coordinate with the overall household, so consumers can only install the air energy water heater on the balcony. But with the improvement of people's requirements for home environment, the big guy on the balcony is not willing to accept.

3. Consumer 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 low. Many people believe that it is impossible to obtain three parts of heat with one part 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 has been very high. People's understanding is only limited to the fact that air conditioners are large consumers of electricity, but they do not know that they are more energy efficient than coal-fired stoves. Nowadays, because some large shopping malls have no air energy water heaters for sale, consumers' awareness of air energy water heaters is still very low.
