Which is better, air conditioning or electric heating, and which is better heating, air conditioning

1. Air conditioning for heating.

Air conditioning heating is to absorb a lot of heat from the outdoor ambient air and transfer it to the indoor while consuming a certain amount of electricity, on average, every 1 kWh of air conditioning heating consumed can transfer the equivalent of 2 kWh of heat from the outdoors to the interior; The heater only consumes electricity to convert electricity into heat, and the power consumption of the heater is greater than that of air conditioning heating under the premise of achieving the same heating effect.

2. Electric heater for heating.

Compared with air conditioners, electric heaters are quieter to run, easy to use, and can be moved at will. Air conditioners are more energy-efficient than electric heaters, so they don't need to be added, which is more space-saving and safer. If you often need to move or heat in a small area, you can add a heater.

If you like the overall heating of the home and stay at home for a long time in winter, use air conditioning for heating.

3. How to choose.

Consumers choose different heating methods, often starting from their own winter heating needs, and most consumers will consider the safety and comfort of heating, as well as the timeliness of portable operation and heating in winter, which are the reasons why we choose different heating methods in winter. The air conditioner shows obvious advantages in terms of convenient operation, temperature control, safety and rapid temperature adjustment. Friends who choose electric heaters may choose electric heaters because of their limited budget, the elderly at home, and specific needs such as local warmth, so they will choose electric heaters as their winter heating appliances.

Air conditioners are better than electric heaters, and the heating of air conditioners is about 800 watts per hour, which is nearly one kilowatt-hour of electricity per hour. The electric heater is also about 800 watts, and the power is about the same as that of an air conditioner. In addition, the air conditioner can warm the whole house, while the electric heater only covers a small area in front of it.

So, it is better to have an air conditioner for heating.

The air conditioning and electric heating are very good, and I feel that the convenience that suits me is the best.

The air conditioner can adjust the temperature.

For students in the south who do not have central heating, winter is not so friendly. The damp and cold weather, the cold room, the cold bed that I dare not lie on. A lot of heating equipment has also come into being.

In the south, the most common heating device in winter should be air conditioning. In the past two years, more and more people have learned about electric heaters and set their sights on electric heaters, especially water and electricity heating. But at the same time, it comes with a lot of questions.

Does electric heating consume electricity? Is it safe? Which consumes less energy than an air conditioner?

Let's follow the golden flagship flag brother to find out.

Today's electric radiator is not the traditional kind of "electric oil tin", and there are many ways to heat it, such as metal heating elements, quartz tubes, ceramic electric heating pipes, etc. Nowadays, however, antifreeze is injected inside, electricity is used to heat the water, and then the heat is dissipated and the room temperature is raised by using the continuous circulation between hot and cold water. Anyone who has used it knows that it has a lot of advantages.

1. Intelligent heating, a variety of configurations: one key to start a comfortable life;

Smart heating, multiple configurations.

2. Newly upgraded graphene heating black technology: the thermal conductivity of graphene coating is 5300W mk, and the thermal conductivity efficiency exceeds that of copper and aluminum materials by more than 10 times, making heating more efficient;

3. High-quality materials: high-quality low-carbon steel double waterway front and rear double pipe heating, super heat dissipation capacity, fast heating speed, safer use;

4. Quadruple protection: Quadruple safety protection, sleep with peace of mind.

5. The use of electricity, a clean energy, so convection electric heating has no emissions, no pollution, no noise, and outstanding environmental protection.

6. It is easy to use, it is heated when the power is turned on, and the power is stopped when the power is off, even in the north where there is central heating, the electric heater can also assist in heating. Some smart models can also be timed and temperature-fixed, and can be freely moved and adjusted in each room.

7. Its purchase and running costs are relatively low.

So compared with air conditioners, which is more practical and more energy-saving?

Usually a 100-square-meter house, the required air-conditioning power is basically about 2400w, open the air conditioning for heating, the speed is slow, the power consumption is large, 1 hour will probably consume electricity, 8 hours a day non-stop heating, a day's electricity consumption is about 19. However, when the air conditioner is heating, the electricity consumption will be greatly affected by the low temperature! If the indoor and outdoor temperatures are low, the air conditioner will be defrosted after the heating is turned on, and the electricity consumption will be greatly increased at this time.

In order to meet the heating needs of different people, the power range of electric radiators is large, ranging from 800W to more than 3000W. The higher the power, the faster the room will heat up, but the corresponding power consumption will be greater. Specifically, power consumption = power use time 1000, taking a 2000w electric radiator as an example, according to the formula, the power consumption of the electric radiator is 2 degrees in one hour.

However, this value is theoretical, because there is a question of efficiency involved. Generally, the energy efficiency ratio of electric radiators is less than 1, the longer the electric radiator is turned on, the electricity consumed will be saved, according to the calculation, the electricity consumption of a day is less than 19 degrees, which is more energy-saving than air conditioning.

Electric water radiators are more recommended, heat dissipation is more comfortable, the air conditioner will be very dry after a while, which is not good for the body, Rubens heating hopes to help you.

Most of the time, the heating effect of air conditioning is better than that of electric heating, but this effect will be affected by many factors, such as outdoor temperature, room sealing, etc., so sometimes the heating efficiency of air conditioning is not necessarily better than that of electric heating, and the main reasons are the following two points:

First, the air conditioner is generally installed in the upper part of the house, and the person is in the lower position, and the hot air is relatively light, which causes the upper part of the house to be very warm, but the height of the person is still cold. The electric heater is generally placed on the ground, which is more likely to produce heat convection, so that the house heats up more evenly.

Second, the air conditioner has wind, the electric heater has no wind, the same temperature environment, the wind will make people feel colder, that is to say, the air conditioner wants to achieve the same effect as the electric heater, then it must create a higher room temperature. The colder the outdoor temperature, the more obvious this defect of the air conditioner, because the air conditioner takes more time to defrost the outdoor unit, and the indoor unit only blows air and does not heat. Of course, the air conditioner can turn on the electric auxiliary heat, but the thermal efficiency is the same as that of the electric heater, and the above factors still suffer.

The humidity of the air will also affect the cooling effect of the air conditioner, when the ambient temperature is below 12 degrees and the humidity is above 70%, the frost of the air conditioner will be more serious, and the heating effect will be worse. It is better to turn on the air conditioner for heating or to turn on the heater for heating, the effect of using the air conditioner completely depends on the local ambient temperature and the air humidity at that time, while the heating or electric heating is not limited by the ambient temperature.

Personally, I think that the effect of electric heating is better than that of air conditioning, air conditioning cannot work normally below minus 7 degrees, and the air outlet of air conditioning is relatively dry in winter. Although electric heaters consume some electricity, they are not limited by the use environment, and they are purely disturbed, and the current electric heaters have the function of humidification, so if you want to be comfortable, it is recommended to consider electric heating. When the ambient temperature is above 12 degrees, it is more energy-saving to use air conditioning.

If the ambient temperature is below 12 degrees, the air conditioner can only work normally if it is defrosted, so the heating efficiency of the air conditioner is relatively low when the ambient temperature pants are low, and the heating effect of heating with the heating system or electric heater is still better.

Although winter has passed, it has now entered the Pibi period when the Spring Festival rolls down. 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 relatively comfortable to use, and it 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, not 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, it needs to consume more gas, 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.

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.

Compared with electric heating, air conditioning has one more cooling function! If it is only heating, the air conditioning effect is definitely not as good as the electric heating effect!

The electric heater was comfortable, the air conditioner was too uncomfortable.
