What is the difference between the structure of an air energy water heater and an electric water hea

Electric water heater is our very commonly used water heater, air energy water heater due to **, environmental and other factors are not commonly used, what is the area between the two, I believe that most people are still more curious, and then through the advantages and disadvantages of electric water heaters and air energy water heaters to see the difference between the two.

The air energy water heater absorbs the heat in the air and compresses the air through the work of the compressor to generate high temperature and high pressure, so as to heat the water. Because it absorbs heat from the air, the ambient temperature has a greater impact on the air energy water heater. In summer, the air temperature is relatively high, and its energy efficiency ratio (COP) is relatively high, which can reach 1:

6。In winter, the ambient temperature is low, and it may be only 1:.

Advantages of Air Energy Water Heaters:

The water storage capacity of the air energy water heater is relatively large, the power consumption per unit water is relatively small, and the use is safe and reliable, and it has the characteristics of conservation, green environmental protection and low maintenance rate.

Disadvantages of Air Energy Water Heaters:

It is not suitable for use in a low temperature state, usually the temperature is below 0 degrees, it is not easy to heat, the purchase is high, and there are certain requirements for the installation environment. The shape is large, the temperature difference dependence is large, the one-time cost is high, the maintenance is difficult, and the heat exchanger and casing heat exchanger are easy to scale and break.

Advantages of electric water heaters:

Instantaneous heating is instantaneous, no need to wait, small size, constant water temperature. **Cheap and easy to install. Because it is installed indoors, there is no problem of low temperature and no heating.

It can adapt to any weather changes, ordinary families can be directly installed and used, and long-term power can provide a large flow of hot water. At present, most of the electric water heaters on the market are also equipped with anti-electric shock devices.

Disadvantages of electric water heaters:

The water storage is small, and the power consumption is relatively high. It is large in size, occupies a large amount of indoor space, is easy to form scale, and wastes a lot of electrical energy. The new electric water heater has a built-in anode magnesium rod descaling device, which solves the problem that the product is easy to scale.

However, the anode magnesium rod must be replaced once every two years, which brings trouble to maintenance.

I believe that after reading the above content, everyone has a certain understanding of electric water heaters and air energy water heaters, and I personally think that electric water heaters are still very durable and easy to use.

Air energy water heaters, also known as "air source heat pump water heaters". The "air energy water heater" absorbs the low-temperature heat in the air, vaporizes it through fluorine medium, and then pressurizes and heats it up after compression through the compressor, and then converts it into water for heating through a heat exchanger, and the compressed high-temperature heat energy is used to heat the water temperature.

Air energy water heaters have the characteristics of high efficiency and energy saving[1], making the same amount of hot water, which is 4-6 times that of general electric water heaters, and its annual average thermal efficiency ratio is 4 times that of electric heating, and the utilization energy efficiency is high.

The electric energy of the electric water heater is converted into heat energy through the resistive thermal device, which acts directly on the water.

Air energy water heaters and general electric water heaters are different in the way they heat water

1. The electric water heater uses a heating pipe to directly heat the water.

2. The air source water heater uses the principle of air conditioning, in short, the air conditioner does not have a heating function, this heating function is to transfer heat to the water, so that the water can absorb heat, so as to achieve the purpose of hot water, and then store the heated water in the water storage bucket for our use.

The structure of the air source water heater is an air conditioner and a water storage and insulation tank, which works to circulate and heat water, which is relatively energy-saving.

The shortcomings of the air source water heater are that it covers a large area, because it is generally 150-200 liters, and there is an external unit, and due to the limitations of installation, it may be far away from the place of use, and it takes a while to release hot water.

The advantage is that it is more energy-saving, because its principle is the same as that of air conditioning, not to use electricity to make hot water, but to use the process of electric heat exchange, and move the heat from the outside to the water heater, so the energy efficiency is relatively high.

Considering investment and other factors, if you use a lot of hot water and use it for a long time for several years, it is more cost-effective to use an air source water heater.

Electric water heater, the advantages and disadvantages of the air source is just the opposite, occupies a small area, can be hidden in the bathroom or kitchen ceiling, close, cheap, simple structure is almost not bad, disadvantages, electric energy consumption is large.

Electric water heaters cost electricity, if the bath is not frequent, about 20 yuan of electricity is used a month, 15 years is 5400 yuan, love bathing, the family electricity bill with a large population will be more, and there is also the situation of electrocution, which is quite scary.

Air energy water heaters are the most energy-efficient water heaters available. The average household consumes 20 to 28 degrees of energy in a month. One ton of hot water is equal to 1000 liters.

Adults need about 30 litres of hot water per day. One ton of water a month is enough. The monthly energy consumption is 7 kWh.

According to the domestic electricity price of yuan, a person may need 5 6 yuan per month, and the electricity bill of an ordinary household is 12 18 yuan per month.

<> family retrofitted and charged a set of triple air conditioners, and used garbage heat** for domestic hot water. In summer, the air conditioner is turned on, the waste heat **, hot water reservation, and the air conditioning is more sufficient. In winter and summer, there is no need to turn on the air conditioner, but you can only turn on the heating and stop the internal fan from rotating, resulting in a shortage of refrigerant and can only be replenished.

The duo had to wait a long time, so they had to add a water heater to the gas for the winter. In the summer, when the air conditioner is turned on, there are several types of snow. Domestic water heaters currently come in a variety of forms.

For example, from previous gas water heaters, solar water heaters, and electric water heaters to air heating systems, electromagnetic water heaters, etc. Every water heater has its advantages and disadvantages. How do we choose?

Let's take an air water heater as an example and give a brief overview of the issues associated with water heaters.

During the cold winter months, due to the lack of a strong and effective insulation, the ends of the owner's water can sometimes cause frost cracking. Once the water supply is interrupted, it will not be able to supply water to the gated energy heater (direct thermal cycle type). The water heater itself has a lot of sensors with self-protection features, but the auxiliary electric heater is a stupid thing, its detection instructions are simple and crude, and if there is a lack of water, it can cause dry burning and burn out the auxiliary electric heater!

Therefore, it is recommended to vigorously strengthen the insulation measures of the owner's water supply during the installation works! Generally speaking, the only common water heaters in the market are electric water heaters and gas water heaters. Do you use gas heaters that don't have electric heaters?

Did you know that there is an air heater in addition to these two water heaters?

1. Air energy water heater, also known as "air source heat pump water heater", its working principle is very similar to that of air conditioner, using a small amount of electric energy to drive the compressor to run, and the high-pressure liquid working fluid evaporates into a gaseous state in the evaporator after passing through the expansion valve, and absorbs a large amount of heat energy from the air; The gaseous working fluid is compressed by the compressor into a liquid state at high temperature and high pressure, and then enters the condenser to release heat and heat the water. By circulating the water to 50°C to 65°C, the water can be heated. In this process, one part of the electrical energy is consumed to drive the compressor to operate, and about four parts of the heat from the ambient air are absorbed and transferred to the water.

Therefore, compared to electric water heaters, air energy water heaters can save nearly 3 4 of electricity energy. That is, the electric water heater consumes 4kw h of electric energy to produce hot water, and the use of air energy water heater only needs 1 kilowatt-hour of electricity.

2. Electric water heater refers to a water heater that uses electricity as an energy source for heating. Electric water heaters can be divided into three types: water storage type (also known as volumetric type or heat storage type), instant heating type, and rapid heat type (also known as semi-water storage type) according to the heating power.

3. Gas water heater, also known as gas water heater, refers to a gas appliance that uses gas as fuel to transfer heat to the cold water flowing through the heat exchanger through combustion and heating to achieve the purpose of preparing hot water.

There are many styles of water heaters, including air energy water heaters and electric water heaters, however, what are the main differences between the two? PChouse will take you to find out.

There are differences between air energy water heaters and electric water heaters, mainly as follows:

First, the principle is different.

Air energy water heater: The air energy water heater works according to the "reverse Carnot" principle, specifically, the "outdoor unit" acts as a heat exchanger to absorb heat from the outdoor air, heat the low boiling point working fluid (refrigerant) and evaporate it, and the refrigerant steam is compressed and heated into the water tank by the compressor, and the heat is released to the water in it and condensed and liquefied, and then the throttle and depressurization are cooled back to the outdoor heat exchanger to enter the next cycle.

Electric Water Heater: Uses an electric heating rod to heat directly in the water.

Second, the energy consumption is different.

Air energy water heater: Air energy water heater has the characteristics of high efficiency and energy saving, manufacturing the same amount of hot water, which is 4 6 times that of general electric water heaters, and its average annual thermal efficiency ratio is 4 times that of electric heating, and the utilization energy efficiency is high.

General electric water heater: The electricity consumption increases with the increase of power, and the energy consumption is higher.

3. Security.

The biggest difference between air energy water heaters and electric water heaters is safety, electric water heaters directly rely on electricity to heat the water temperature, which is dangerous; The air energy water heater is by absorbing the heat in the air, heating the water temperature, and the water and electricity are not in contact during operation, and the safety is high. Safety vs. air energy water heaters win.

Air energy water heater and electric water heater are completely different in heating form, the traditional electric water heater mainly relies on electric energy heating, in the internal structure of the water heater, there is a special heating element, which can assist the water in the water heater tank to complete the heating. The heating method of the air energy water heater is completely different, it does not have a fixed heating element, the reason why the hot water can be heated quickly, and the efficient heating is mainly due to the compressor in the operation, the heat energy in the air is rapidly compressed and transformed, and finally the heating of the hot water is completed. The air energy water heater consumes the heat energy in the air, while the electric energy water heater consumes electricity, and the two are completely different planning principles.

Secondly, electric water heaters and air energy water heaters are also very different in terms of safety factor, as everyone knows, traditional electric water heaters in the process of use, water and heating elements are each other, so in the process of heating operation, the probability of electric water heater leakage is very large. The air energy water heater does not have a heating element, and it is also very advanced in safety planning, separating water and electricity for planning, and the biggest advantage of this planning method is that it has a high safety factor. This is also the main manifestation of the difference in principle between the two types of water heaters, and for consumers, the advantages of air energy water heaters in the safety factor have also been recognized by consumers.

In addition, there is a big difference in the environmental protection index of the two kinds of water heaters, the first thing we know about efficient heating, the electric energy water heater consumes electricity, and the consumption of electric energy will not only form a waste of power, but also form environmental pollution, because the electric energy is consumed, various harmful gases will be discharged, and these harmful gases have a great impact on the environment. The air energy water heater will not be discharged any gas when it is running and heating, because its heating form is only a change process, only the compressed cold air discharged can be directly discharged into the room for recycling. On the whole, I personally think that air energy water heaters are more suitable for the green life needs of modern people.

1. Different heating methods: electric water heaters mainly rely on electric energy heating, gas water heaters are heated by burning gas (natural gas, liquefied petroleum gas or coal gas), and air energy water heaters also use electricity, but they do not directly use electricity to heat, but use a small amount of electric drive compressor to work and absorb heat in the air for heating.

2. The safety factor is different: electric water heater and gas water heater will leak electricity and air leakage, while the air energy water heater has no heating element, and it is also greatly advanced in safety design, and the water and electricity are separated from the design, and the biggest advantage of this design method is that the safety factor is high.

3. The environmental protection index is different: the air energy water heater is the most environmentally friendly, it does not use electricity and does not produce exhaust gas during the heating process, and the energy consumption rate is the lowest and the most environmentally friendly.
