What is air energy?

Question 1: What do you mean by air energy? Air energy is a kind of low-grade energy, which exists widely, is given equally and can be used freely. Using heat pump cycle to improve its energy grade is used to heat domestic hot water. Because 1 part of electric energy can absorb 3 parts of air energy and supply 4 parts of heat energy to heat the hot water system, it is a new energy-saving and environmental protection technology with great development and application potential and great practical value.

Recently, a new product named "air energy water heater", known as the fifth generation water heater, has been hyped in major media, boasting that it can save energy by more than 70%, which is really extraordinary.

The economic and social value of "air energy water heater" in terms of high efficiency, energy saving, popularization and use has been widely publicized and reported in major newspapers, networks and other media. The report claims that "air energy water heaters will replace gas water heaters and electric water heaters in the near future" and that "the popularization and use of air energy water heaters will save a Three Gorges power station".

According to reports, the air energy water heater adopts the principle of inverse Carnot cycle, which is driven by electric energy. Through the work of compressor, the heat-absorbing working medium produces physical cycle phase change, and the cold water is heated to produce hot water by the process of heat absorption and heat release of heat exchanger. But how much electricity is really consumed? How much heat energy is absorbed from the air? Do you really save so much? Whether the air energy water heater is really so energy-saving remains to be studied.

Question 2: What is the so-called "air energy"? At present, there are two technologies that claim "air energy" in society: one is pseudoscience, and the other is true science, which can save energy.

The former actually uses compressed air to do work.

Originally, this is just a way to store energy, because it is necessary to consume energy to compress air first, and then the output work may actually be less than before. But propagandists lie that they can "get energy from the air" and output more work (so they call it "air energy"). This kind of propaganda is a "perpetual motion machine" scam. Such as Tian Xiang's "Aerodynamic Core Energy", Beijing Huada Brother Kangbu Aerodynamic Generator and so on.

The latter (so-called air heating) is not used for doing work, but for heating.

It uses the principle of heat pump to extract some heat from the ambient air while consuming energy (electricity), and deliver it to the users who need heat together with the heat converted by electricity. Compared with the simple "burning electricity to generate heat" in the past, this technology greatly reduces the waste of energy and has the significance of energy saving.

Although the latter is real science and technology, its propaganda also has a defect, that is, the term "air energy" is easily misunderstood and used by swindlers like the former as "evidence" for their propaganda of pseudoscience.

Refer to the post of Air Energy: The so-called "Tian Xiang Air Energy" is a pseudo-scientific scam. It has nothing to do with the air heating technology in this bar.

Question 3: What is the main function of air energy? "Air energy", which is often said now, is the abbreviation of a product. In fact, it refers to air energy water heaters, also known as air energy water heaters, air source water heaters, air source heat pump water heaters, air source heat pump water heaters, and heat pump water heaters. Please refer to: air energy water heater, energy-saving water heater, central water heater. This new type of water heater consists of a heat pump host similar to the outdoor unit of an air conditioner and a large-capacity pressure-bearing thermal insulation water tank. Its installation is not limited by buildings or floors, and its use is not limited by climatic conditions. It can be used as a hot water supply center for families or as a centralized hot water supply for units. Due to the adoption of new patented technology in all aspects of the environment, this product is not only safe and comfortable, but also environmentally friendly and energy-saving. The actual usage fee is only equivalent to 1/4 of electric water heater and 1/3 of gas water heater. To heat the water in the 150 liter water tank to 65℃, it takes 2 kwh of electricity in spring and autumn. If the low electricity price is adopted, only 0.6 yuan money is needed, and the hot water stored in this water tank is enough for a family. If you take a bath with a faucet, the water heater can continuously supply hot water. Experienced users can set the hot water temperature at 45℃, and the operation of the water heater will be more energy-saving! Air energy is a kind of low-grade energy that exists widely, is given equally and can be used freely. After the energy level is improved by heat pump circulation, it can be used to heat domestic hot water. Because one electric energy can absorb three parts of air energy and supply four parts of heat energy to heat the hot water system, it is a new energy-saving and environmental protection technology with great development and application potential and great practical value. In addition, the air energy heat pump water heater fundamentally eliminates the potential safety hazards such as electric water heater leakage, dry burning, harmful gas generated when gas water heater works, overcomes the shortcoming that solar water heater can not work in rainy days, and has many advantages such as high efficiency, energy saving, safety and environmental protection, all-weather operation, convenient use and so on. In line with the strategic policy of sustainable development of energy, society and environment in China, it will become the most competitive new generation water heater product in China, providing safe, convenient and cheap sanitary hot water for urban and rural residents. How does the air (heat pump) water heater work? Through the operation of the compressor system, the heat in the air is absorbed to make hot water. The specific process is: the compressor compresses the refrigerant, and the compressed refrigerant with increased temperature passes through the condenser in the water tank to make hot water. The refrigerant after heat exchange returns to the compressor for the next cycle. In this process, the heat of the air is absorbed by the evaporator and introduced into the water to produce hot water. This new generation of water heater heated by compressor air is air (heat pump) water heater. Air (heat pump) water heater is such a product. This is the working principle of air (heat pump) water heater. When the air energy heat pump is running, the evaporator absorbs heat from the environmental heat energy in the air and evaporates the heat transfer working medium. After the working medium steam is compressed by the compressor, the pressure and temperature rise. When the high-temperature steam is condensed into liquid by a special annular tube condenser permanently bonded to the outer surface of the water storage tank, the released heat is transferred to the water in the water storage tank of the air source heat pump. The condensed heat transfer working medium returns to the evaporator through the expansion valve, and then is evaporated, and so on. The heat transfer working medium of air source heat pump is a special substance, whose boiling point is -40℃ and freezing point is below-100℃ under normal pressure. This substance is liquid when it is cold, but it easily evaporates into gas, and vice versa. In actual operation, the evaporation limit temperature of heat transfer medium in air source heat pump is about -20℃, so the ambient temperature of 5℃ is "hot" for such a low temperature, even the snowy temperature, such as 0℃, is hot by comparison, so some heat energy can still be exchanged. Edit the characteristics of air energy in this paragraph. What are the advantages of air (heat pump) water heaters? "Safety+saving money+comfort+environmental protection": 1. Safety: no gas is used, no waste gas will be generated, and "gas poisoning" will not occur; There is no need to use an electric heating rod for heating, so there is no danger of electric leakage, which protects the health and safety of family members. Air energy 2, saving money: COP value greater than 3, high energy efficiency ratio, absolutely saving electricity and money. It can save 2/3~3/4 of the electricity fee, or 1/2~2/3 of the gas fee and the auxiliary heating fee of the solar water heater. 3. Comfort: patented technology-indirect over-current heating, automatic constant temperature and constant pressure water supply, and hot water is never cold or cold. & gt

Question 4: What can air do to generate electricity? If it is helpful, please adopt it, or click on the top right corner to be satisfied, thank you! !

Question 5: What is air energy? Air energy can be summarized as energy contained in air, that is, low-grade heat energy contained in air, also known as air source.

"Air energy", which is often said now, is the abbreviation of a product. In fact, Fa refers to air energy water heater, also known as air energy water heater, air source water heater, air source heat pump water heater, air source heat pump water heater and heat pump water heater.

Question 6: What does air energy water heater mean? Is it different from ordinary electric water heaters? The working principle of gas-fired energy water heater is "Inverse Carnot" principle, that is, the "outdoor unit" compresses the air like a pump to raise the air temperature, and then conducts the heat to the indoor water storage tank through a liquid boiling at-17℃, and then releases the heat to the water. Using the working principle of heat pump to heat is contrary to air conditioning refrigeration-the national refrigeration standard is 1000 watt, and the electric refrigeration is 2800 watt. According to the principle of heat balance, at least 2800 watts of heat is generated at the same time, and the actual heat generated is 3000-4000 watts with 0,000 watts of power input. When the heat is delivered to the insulated water tank, the power consumption is only one quarter of that of the electric water heater (even if the thermal efficiency of the electric water heater is 1 1,000%, the input of 1 1,000 watts is only 1 1,000 watts). Air energy water heaters do not need sunlight, and can be placed at home or outdoors. It is difficult to produce hot water immediately after the water stored in the solar water heater is used up. If the electric heating takes a long time, and the air energy water heater can run under pressure for 24 hours as long as there is air and the temperature is above zero degrees Celsius. In this way, even if one box of water is used up, another box of hot water will be produced in an hour or so. At the same time, it can fundamentally eliminate the potential safety hazards such as electric water heater leakage, dry burning, harmful gas generated when gas water heater is used, overcome the shortcomings of solar water heater that it can not be used in rainy days and is inconvenient to install, and has many advantages such as high safety, high energy saving, long service life and no toxic gas emission. The service life of air energy water heaters can generally reach 15 to 20 years.

Question 7: What is air energy air conditioning? Whether it is cooling or heating, the working hours of air conditioners are generally longer every day, and the space for cooling/heating is relatively large, so the cold/hot air produced is easy to lose, and the working power of air conditioners is higher than that of air energy.

Although the power supply of the air energy water heater is always energized, when the heating is completed, the unit will stop working and automatically keep warm. There is no need to consume electricity in the heat preservation process, and the heat preservation effect of high-quality water tank can reach more than 72 hours. Generally, the working hours of household machines will not exceed 2 hours a day, so air can save more energy than air conditioning, protect the compressor better and have a longer service life.

You can plug in air every day, which consumes electricity when you work, and you don't need to consume electricity when you keep warm. The purpose of plugging in electricity at any time is to keep the water temperature of the air energy tank between 45-55℃ and ensure that there is hot water for 24 hours.

Generally, air conditioners, whether cooling or heating, have long working hours every day, and the space for cooling/heating is also relatively large, so the cold/hot air produced is easy to be lost, and the working power of air conditioners is higher than that of air energy.

Question 8: What are the advantages and disadvantages of air? Advantages 1: Safe and reliable.

Compared with electric water heaters and gas water heaters, air energy water heaters completely eliminate the potential safety hazards of electric water heaters and carbon monoxide poisoning of gas water heaters. The water temperature is constant, unlike the solar water heater, where the water temperature reaches the boiling point in summer, and scalding accidents will occur if it is not used carefully.

Advantage 2: energy saving and environmental protection

The heating efficiency of air energy water heater is twice that of solar water heater and four times that of electric water heater. According to estimates, a family of three using air energy water heaters can save 2000 yuan a year, which is the most efficient water heater at present and has obvious energy-saving characteristics. The air energy water heater will not produce any toxic gas that pollutes the environment during its operation.

Advantage 3: Comfortable and convenient.

The air energy water heater has a strong adaptability to the environment, and it needs air to heat, which really realizes 24-hour hot water. The air energy water heater has a large water output, which can be used by multiple water points at home at the same time, and is comfortable and convenient to use.

Advantage 4: kitchen air conditioning

The cold air discharged by the air energy water heater can be collected and used in the kitchen, which can alleviate the sweltering heat in the kitchen in summer and be used for ventilation and dehumidification in the rainy season, so as to achieve the effect of multi-purpose and make life easier.

Advantage 5: WeChat control

Air energy water heater is the most intelligent water heater, such as Fanny air energy water heater. As long as WeChat pays attention to an official WeChat account, it can realize remote control and control the air energy water heater at home anytime and anywhere.

Advantage 6: Long service life

The electric water heater must be replaced after 10 years. Solar water heaters are subjected to wind and rain all the year round, and their operation is unstable. The design life of air energy water heaters is generally 15 years, and some even reach 20 years. Moreover, with the continuous maturity of air energy water heater technology, the warranty period provided by manufacturers is getting longer and longer (the highest warranty period in the whole finney air energy water heater industry is 6.5 years), which brings more protection to users.

Disadvantages 1: environmental adaptability

Solar water heaters use air as heat energy. Although air can be used for heating, there are still certain requirements for the ambient temperature, which is generally between 0℃ and 40℃. The winter temperature in northern China is generally below 0℃, so it is difficult for air energy water heaters to achieve their due heating effect, or even to start. Therefore, the air energy water heater installed in northern families can only be installed indoors to ensure the normal work of the machine.

Disadvantage 2: huge volume

Huge volume is one of the main disadvantages of air energy water heater, which is only suitable for installation on the ground (balcony or roof), resulting in some units not being installed, and some users can't accept such huge volume and give up air energy water heater and switch to other water heaters.

Disadvantage 3: technical shortcomings

Air energy water heater is a new thing in China, but there are still some shortcomings in technology: for example, frosting is the main reason that restricts the air energy water heater industry from crossing the Yellow River and fighting in the North; If the compressor is easy to be damaged, some compressors with circulating heating system in the market run at high temperature and high pressure for a long time, which accelerates the aging and carbonization of the compressor and leads to the easy burning of the compressor.

Question 9: What is an air energy water heater and pictures? For a simple example, a car can transport several tons of goods from one place to another with several liters of gasoline. Air energy units can absorb heat from nature, and through the "handling" of heat pumps (electric power works to drive heat pumps), they can obtain heat energy that can be used for production and life. Its biggest feature is energy saving.

Question 10: What brand of air can be returned to the landlord? The primary criteria for judging the quality of air energy water heaters are:

First of all, look at the brand, you can refer to the top ten rankings of 20 14 air energy.

Second, look at the compressor. At present, Panasonic compressor in Japan is the best compressor in China. Of course, Asia's air energy industry is also at the forefront of Japan. Midea, which ranks first, uses 1P small compressor (Midea and joint venture), Gree, solar rain and air.

Third, look at cop, energy efficiency ratio = heating capacity ÷ rated power. Here, we compare the cop of the top ten products, conduct a sampling survey, and extract product data from official website.

1, Gree Water Love, heating capacity 3 100W, power 886W, COP 3.49, reference price 5220 yuan,

2. Midea KF66 has a heating capacity of 3 100 W, and the power supply cannot be found. Directly bidding for the country 1 energy efficiency (), the reference price of 5480 yuan is also drunk;

3. Benefiting from the sun and rain, the heating capacity is 3500W, the power is 920W, the COP is 3.8, and the reference price is 5470. Under the same conditions, the higher the energy efficiency, the better the overall operation of the whole machine. Of course, the technical difficulty and research and development cost will be higher.

Fourth, listening to the noise can judge the stability of the compressor operation, and the noise of the main engine will also affect the normal rest.

Fifth, look at the insulation effect/insulation technology in winter. At present, the air energy water heater is very intelligent. As long as it reaches the set temperature, it will automatically stop heating, and as long as it drops to a specific temperature, it will automatically start heating. So heat preservation is the key to saving electricity and comfort. It is not recommended to buy too small air energy, such as wall-mounted air energy. The smaller the water quantity, the faster the heat dissipation (what is the physical principle? ) It will be a bit embarrassing to keep warm badly in winter. Water tanks in the sun rain have insulation walls, which can achieve long-term insulation.

Sixth, looking at the water tank is actually looking at the leak-proof performance and thermal insulation performance of the water tank. If it is leak-proof, it depends on the water quality. If the water quality is not good, it is recommended to buy a water tank with an enamel liner. There is still a difference between north and south. At present, most domestic manufacturers have begun to eliminate stainless steel liners and replace them with enamel liners. As long as the porcelain is not exploded (in layman's terms, the enamel on the liner falls off due to violent collision), there is no problem in using the enamel liners for more than 15 years.

Above, I hope I can help you.
