Which is more comfortable to save electricity, air conditioning or electric heating?

Definitely the air conditioning was a bit more comfortable. The heating principle of an electric heater is actually baking, heating the copper wire or heat storage material inside, and then releasing the temperature into the air. The air conditioner starts the compressor inside the air conditioner to transfer the heat from the outdoor air to the compressor, and then blows the hot air into the room by blowing.

Generally speaking, the amount of heat generated by an air conditioner is much greater than that of an electric heater for the same amount of electricity. In addition, the air conditioner will stop when the room temperature reaches the set temperature, but the electric heater will continue to work. Of course, if you only need to warm your hands and don't need to heat the whole room, it must be that the air conditioner uses more electricity.

Haier air conditioning. The use of dual-rotor compressor and the matching inverter system, when the two rotors work at the same time when running under high load, it can easily provide energy, and when the temperature drops, it becomes a single rotor to run alternately, which is very silent and energy-saving, avoiding frequent opening, so that the compressor can maintain a stable running state, which is very energy-saving.

Air conditioning is more energy-efficient than electric heating, and the range of electric heating is relatively small, and the heat is relatively limited; Air conditioners have an advantage over electric heating because they exhaust hot air through vents, allowing heat to spread over a wider area. However, in winter, the air will become extraordinarily dry, and the throat will be easily inflamed, the best way to use the air conditioner is to put a basin of water on the ground, and then put a wet towel on the air conditioner outlet, and then drink more hot water, it will be much better.

Air conditioning uses a lot of electricity compared to electric heating.

1. Trial power.

Take, for example, the need for a 20-square-meter room.

1. Heater: suitable for heaters with a power of 1800 watts.

2. Electric heater: suitable for electric heater with a power of 2000 watts.

3. Air conditioner: suitable for 2 hp air conditioner.

Second, energy efficiency ratio:

1. The energy efficiency ratio of the heater: 1:1, consumes 1000 watts of electricity, and generates 1000 watts of heat.

2. The energy efficiency ratio of the electric heater: 1:1, consuming 1000 watts of electricity and generating 1000 watts of heat.

3. The energy efficiency ratio of fixed-speed air conditioner: 1:3, consuming 1000 watts of electricity and generating 3000 watts of heat.

3. Comparison of fixed-speed air conditioners, heaters, and electric heaters

1. The energy efficiency ratio of air conditioning is high.

The heating power of the fixed-speed 2 hp air conditioner is 3300 watts, which can generate 6900 watts of heat, which can increase the temperature of the whole room to 20 degrees, and has good comfort.

2. The energy efficiency ratio of heaters and electric heaters is low.

Even if you use a heater or electric heater that consumes 3,300 watts, it can only produce 3,300 watts of heat, which is less than half of the same power fixed-speed air conditioner and less than one-third of the same power inverter air conditioner. It is only suitable for local heating, which has little effect on raising the temperature of the whole room, and the comfort is poor.

It can be seen from this: 1. Compared with the heater and the electric heater, it is recommended to choose the heater, and it is best not to use the electric heater.

2. Compared with air conditioners, heaters and electric heaters, it is recommended to choose air conditioners, and it is best to use inverter air conditioners.

Air conditioning is more power-efficient.

Someone did an experiment in the same room, heating with electric heating and air conditioning for one hour, and the results of the experiment were as follows:

Electric heating: The operation time is 1 hour, the consumption of electricity, according to the electricity price of one kilowatt-hour for the yuan, then the staring liquid, the cost of turning on the electric heating for one hour is yuan.

Air conditioner: The running time is 1 hour, the consumption of electricity, according to the electricity price of one kilowatt-hour for the yuan, then, the cost of turning on the air conditioner for one hour is yuan.

Judging from the above results, air conditioning does save a lot of electricity compared to electric heating, and it also saves nearly half of the electricity bill.

1. Compared with the heater and the electric heater, it is recommended to choose the heater, and it is best not to use the electric heater.

2. Compared with air conditioners and heaters, it is recommended to use air conditioners, and it is best to use inverter air conditioners.

Now there are many heating products on the market, air conditioning, floor heating, fan heaters, electric heating, so many heating products, although the increase is cleared of the choice space, but it also makes it more difficult for consumers to choose, can only compare the characteristics of each heating product to choose. Naturally, power consumption is also one of the comparison parameters, so is electric heating energy-saving, and which is more energy-efficient compared to air conditioning? Let's take a look.

Electric heaters and electric heaters are equivalent to pure resistance in electrical circuits, so their input power is equal to the output power. Assuming the input power is 1000W, then the output power is also 1000W.

The power consumption of electric heater is constant, as long as you turn it on, then it will always consume power according to the gear you set. What's more, the space for heating electric heaters is very limited, which is only suitable for electric heaters to heat up at close range, and only suitable for a few people to heat together.

The air conditioner assumes that the power is 1000W, and the energy efficiency ratio of the general air conditioner is at least 2 or more, and the formula of the energy efficiency ratio is: energy efficiency ratio = output power input power. Therefore, with 1000W input power, the output power of an air conditioner with an energy efficiency ratio of 2 is 2000W.

Whether it is refrigeration or heating, the range of use of air conditioning is cooling or heating in the entire enclosed space, and its space use range is large, which can ensure that the whole space is cool or warm. In addition, once the set space temperature is reached, the air conditioner compressor will shut down, and the power consumption of the air conditioner is very low (only the electrical control circuit works), so as long as we set the temperature of the air conditioner properly, we will save a lot of electricity.

To sum up, if the input power is the same, then the effect of the air conditioner will be better; If the output power is the same, then the air conditioner is more power-efficient.

Although air conditioning is slightly better than electric heating in terms of power saving, electric heating also has the advantages of allowing consumers to choose, for example, it can easily and quickly control the temperature of electric heating by turning on and off the power supply, no indoor pipes, the product itself is delicate and beautiful, no need to decorate and package, easy to use, no noise and so on.

Therefore, which heating product is better, you can't generalize, and you can't just choose based on a certain feature. All I can say is that choosing the right one is the best.

Air conditioning heats and saves electricity.

Under the condition of raising the same room temperature, from the actual use of power consumption, air conditioners are actually more energy-efficient than electric heaters. Electric heating wire is a relatively simple and direct heating method, so the relative power consumption is also greater, so in terms of energy saving, air conditioning is better than electric heating.

Principle:

Air conditioning and electric heating are mainly distinguished by the principle of heating, the principle of general air conditioning heating is heat pump, which completes a complete heat cycle internally, while the heating principle of heater is electric heating wire, relying on high and low temperature difference circulation heat dissipation. Electric heaters are the highest if they are 100% efficient, but air conditioners can reach 280% at will, which means that 1 kilowatt-hour of electricity can be used for air conditioning heating.

The difference in heat exchange mode also determines the difference in power consumption between the two. Generally, a horsepower air conditioner can ensure the heating effect of a room of about 15 square meters, and to achieve the same heating function, the heater generally needs more than 2000W of power. Electric heating wire is a relatively simple and direct heating method, so the relative power consumption is also greater, so in terms of energy saving, air conditioning is better than electric heating.

However, many people think that it takes a lot of electricity for the air conditioner to warm up the whole room. In fact, when using air conditioning for heating in winter, in addition to compressor operation, electric auxiliary heating is also required for air conditioner heating. That is, on the basis of the power consumption of the air conditioner in summer, the power will be increased by 500 to 1000 watts, that is, it will consume more electricity than in summer when used for the same time.

However, compared to heaters, using heaters in the home actually consumes more electricity.

Everyone thinks that how can an electric heater cost more electricity than an air conditioner, it must be impossible. However, the power consumption of the electric heater is actually related to its operating power, so the higher the power of the electric heater, the more power it consumes in actual use.

Electric underfloor heating consumes the most electricity, and air heating is the most energy-saving and energy-saving.

The power consumption of the air energy heat pump when driving the fan coil unit is almost the same as that of the air conditioner, there is no difference. If the floor heating is driven by air energy, the work efficiency of air energy is higher due to the low temperature of hot water demand, and the overall power saving is relatively high.

Air energy refers to the low-grade thermal energy contained in the air. However, according to the second law of thermodynamics, it is impossible for heat to be transferred from a low-temperature heat source to a high-temperature heat source without causing other changes. Therefore, on the basis of not consuming external energy, the air cannot be used.

Heat pumps can absorb heat from the air and transfer it to high-temperature objects or environments, this technology is called air source heat pump.

The use of heat pumps requires the consumption of electricity or heat. For example, an air conditioner in your home is a typical air source heat pump when it is used to heat in the winter, but it does not heat without electricity or heat. Therefore, air source heat pumps are not driven by air energy, but by electric or thermal energy.

Air source heat pumps can be used in many fields such as heating, heating, and drying.

In contrast, the air conditioner not only saves a little electricity, but also the whole room is warm and comfortable.

Electric heaters not only consume electricity, but also tend to feel dry and uncomfortable when used for a long time.

However, the heating of hail air conditioner is greatly affected by the outdoor ambient temperature, and when the outdoor ambient temperature is high, the heating effect is particularly good, and it is also very energy-saving. However, when the outdoor ambient temperature is very low, the heating effect is obviously reduced after the opening degree of the minus five chains, and it is also very power-consuming.

Air conditioning is more energy-efficient than electric heating. The air conditioner is only a heat porter, and when heating in winter, the compressor transfers the outdoor heat to the compressor infiltration stove, and then sends the hot air to the room by blowing. Despite its high power during operation, its heating efficiency can generally reach 1:

3。The electric heater is used to heat the internal copper wire or heat storage material through the consumption of electricity, but the heat is released into the air, that is, the electrical energy is directly converted into heat energy, and the heating efficiency can reach 1:1. From the point of view of heating efficiency, electric heaters are more power-intensive.

Precautions for using air conditioners for heating.

The air outlet of the wall-mounted air conditioner is far from the ground, the density of hot air is lower than that of air, and the hot air can only float above, and the heat of the soles of the feet is low, and the body always feels unwarm. In order to make heating more efficient, many people will turn on the electric auxiliary heating function. The working mode of this function is similar to that of electric heating, which directly converts electrical energy into heat energy, which greatly reduces the original heating efficiency of the air conditioner and is bound to increase power consumption.

Therefore, as a last resort, the use of electric auxiliary heating function should be minimized.

Although winter has passed, it has now entered the Spring Festival period. But since many people have been asking before, which heating method is better? Now I'm going to summarize which one is better.

There are generally air conditioners, floor heating and radiators to keep warm, but which one is cheaper and safer?

1. Radiators.

The advantage of radiators is that they can heat up as soon as they are turned on, and sometimes they need to drain some cold water, but not much. The radiator is more comfortable to use and will not be very dry.

Radiator radiator heats up as soon as it is turned on, sometimes you need to drain some cold water, but not much. The overall comfort is good, and it won't be too dry.

If you want to install, you can plan it before you renovate. Under normal circumstances, a house of 100 yuan costs about 20,000 yuan.

The radiator is also hot water, it has to reach more than 60 degrees to evenly dissipate heat, and it needs to consume more gas to shoot the stove, take 100 room temperature to reach 20 degrees, generally 15m of gas, a month to have more than 1100 yuan.

2. Floor heating. Floor heating is mainly laid under the floor or under the tile, relatively speaking, the heat dissipation of floor heating is relatively uniform. However, one thing to note is that before the renovation of your new house, you should be prepared to lay floor heating, and do not think about this matter after the decoration is completed.

Floor heating ranges from 10,000 to tens of thousands, depending on the type of floor heating, generally 100 floor heating ** in about 25,000.

Compared with radiators, underfloor heating only needs to reach 45°C to heat the room. The conversion efficiency of floor heating is relatively high, and the gas cost is also less. Heating a 10-square-meter room by 20° is less than 1,000 yuan a month.

3. Air conditioning. In fact, the air conditioner also has the effect of providing heating, as long as the heater is turned on, and it will come immediately. In a month, it may cost six to seven hundred yuan. However, it has the advantage that it can be installed and replaced at any time. The bad thing is that it will make you feel dry and sensitive.

To sum up, it may be that the cost performance of floor heating will be better than the other two, and the comfort is also better, and friends who do not have decoration can consider it. But if your home needs floor heating for less than a month in a year's weather, it may be good to install an air conditioner, and the hot and cold effect will come.

The air conditioning is not only relatively economical, but the whole room is warm and comfortable.

Electric heaters not only consume a lot of electricity, but are prone to dryness and discomfort when used for a long time.

However, the heating effect of air conditioning is greatly affected by the outdoor ambient temperature, when the outdoor ambient temperature is very low, usually lower than minus five degrees, the heating effect is significantly reduced, and the power consumption is also very large.
