Do I still need to install HVAC after installing air conditioning, and if I already have an air cond

If you install an air conditioner, you still need to install HVAC, which is nothing to dispute.

In the north, winter temperatures are below freezing, and even the best air conditioners will not be able to do it in such climates. However, the northern region generally adopts the method of central heating, so there is basically no need to worry about the problem of heating.

However, in the area south of the Yangtze River, although the winter temperature is relatively high compared to the north, coupled with a series of factors for energy conservation and emission reduction, central heating has not been implemented. But just because it's hot doesn't mean it's hot. In winter, the south is often an indoor temperature and an outdoor temperature, and I believe that there is no powerful heating measure, and people can't stand it.

Since there is no central heating in the south, you can also surround a fire pit in the countryside, but in the city, you can only blow the air conditioner. However, winter temperatures in the south are not as pleasant as textbook descriptions, and it is normal for temperatures to fall below freezing.

It has been reported that when the outside temperature drops below five degrees, the heating capacity of the air conditioner is reduced. In the event of a cold winter, once the temperature drops below minus 7 degrees, there is basically no evaporation process for Freon, which is either ineffective or cannot be started. Therefore, it is extremely unreliable to rely on air conditioning for heating in winter.

In addition, air conditioning heating is only an auxiliary means of heating in winter, and the heating capacity is not comparable to its cooling capacity, and most of the air conditioners are purchased in midsummer, and the business propaganda only emphasizes his refrigeration, and the description of the heating capacity is very vague, and it is too late when you find a problem in winter.

Also, blowing the air conditioner for a long time is easy to get sick with air conditioning, and it will also cause dry air and cause physical discomfort.

Then consider the cost of heating. The air conditioner is still very annoyed when it is turned on 24 hours a day, and the meter is stuffy and running. It is said that the installation of HVAC will be relatively small at first, or how can it be said in the news that it is highly energy-efficient.

Therefore, it is necessary to install HVAC. These are all told to me by my friends [Shangjia HVAC], I don't dare to say it if I exaggerate, the facts are there, just think about it.

Extra points

There are many ways to heat the house, but in the long run, any country will implement sustainable building energy efficiency policies. Either way, energy saving is the first element, and comfort is the second. Because it is both energy-saving and comfortable, floor heating is widely used in developed countries such as Europe and the United States, and more than 50% of it is used for floor heating at the end of heating.

Yes, the air conditioner was on for a long time and it was uncomfortable.

It is a misunderstanding that the installation of air conditioning does not need to install heating, after all, the two specialize in different aspects, the difference between air conditioning and radiator is still quite large, the radiator is simple to use, high heating efficiency, strong comfort, is the main heating equipment of modern home, as long as the user masters the correct use and maintenance methods, you can enjoy the winter warmth comfortably and comfortably.

Air conditioning and radiators as the public's favored heating methods, how to choose, in fact, the difference between air conditioning and radiators is not small, they complement each other, one focuses on cold, one focuses on heat. If you're after a more comfortable temperature, air conditioning may not be a priority. So what is the difference between air conditioning and radiators, let's learn about it with Brother Jin's flagship.

Difference Between Radiator and Air Conditioner: The heating method is different.

The radiator adopts the convection method, which makes the indoor heat up quickly through heat transfer and heat dissipation, and the radiator can also place some decorative items, quickly bake some wet clothes, fabrics, etc.;

Air conditioning heating can comfortably send heating air, not easy to get air conditioning disease, and can achieve large-scale heating. Air conditioning** is generally more expensive.

Difference Between Radiator and Air Conditioner: Comparison of Heating Levels.

The biggest advantage of the radiator is that it heats up quickly, it can be used immediately, and the indoor temperature can be quickly increased within half an hour. Although the air conditioner has the dual functions of heating and cooling, it was first designed for refrigeration, so the heating effect in winter is not ideal, the lower the outdoor temperature, the worse the indoor effect, the air conditioner will have defrosting in winter, and the defrosting process will cause the indoor temperature to fluctuate greatly.

Difference Between Radiator and Air Conditioner: Comfort Contrast.

The radiator heating efficiency is very high, and you don't need to wait for a long time to enjoy the warmth in the cold winter, and the heat dissipation is even, and the cool head is more comfortable. Air conditioning and heating are directly blown out of hot air through mechanical power, which will not only make the indoor air relatively dry, but also not good for human health; The circulation mode of heat is from top to bottom, so that the upper space of the indoor temperature is higher and the lower space is low, which does not meet the comfort requirements of "the head should be cold and the feet should be hot".

The difference between radiator and air conditioner: comparison of heating operating life.

Radiators and air conditioners have an operating life of about 15-20 years, which is comparable.

Looking at the heating comparison between radiators and air conditioners, it is not that air conditioners can not be heated, but that considering various factors, air conditioning is not the best choice for heating. In addition, radiators and air conditioners can coexist, and there is an air conditioner at home and a radiator system. Radiators and air conditioners complement each other, one focuses on cold and the other focuses on heat.

If there is an air conditioner, you can do without radiators, and the northern compatriots will not be able to live from the cold for a long time.

If you have the money, you can fill it up, after all, it works better in the winter than the air conditioner. And with the improvement of people's living standards now, I feel that I can live as I want.

It depends on the individual's needs, the conditions and the region where it is located.

For example, in the Northeast, it is not enough to rely on air conditioning to heat in winter, so it is definitely necessary to install a central heating system or a separate heating system to achieve winter heating.

In other areas, users have clear needs for use and have the relevant economic conditions, they can use air conditioning to achieve cooling in summer and heating in transitional seasons, and use heating in winter to achieve the best comfort.

The comfort of using air conditioners for heating will be skewed, and the effect will not be too good.

Hello landlord. Personally, I recommend that you install it, the air conditioner has a limited capacity for heating and heating, and the comfort is not very high; Especially in the northern regions, it is not enough to rely on air conditioning to heat in winter. At this time, it is necessary to install special heating equipment to achieve good heating in winter, and air conditioning is used to heat in the transitional season and cool down in summer, so it is still necessary to install heating, and the above answer hopes to help you!

Install a heater. Heating is economical and practical. Turning on the air conditioner is expensive. There are elderly people and children who are not as good as heating.

Of course, it is necessary to install it.

Air conditioners and radiators are actually different.

Air conditioning in the summer and radiators in the winter.

In winter, if the air conditioner is used for heating, because the air conditioner is installed on the top of the house, and the air conditioner is a direct blowing type, our heads have felt warm, but our feet are still cold, and the air conditioner will cause the room to be very dry and easy to get "air conditioning disease".

The radiator is radiant + convection mode of heat dissipation, which meets the needs of the human body, and the radiator heats up quickly, is convenient to control, has a good heating effect, does not need to wait for preheating, and is efficient heating.

If you want to install it, you can learn about German HM

Installed ** air conditioning can also be installed with heating. We all know that air conditioners are divided into single cooling air conditioners and cold and warm air conditioners, and most of us use cold and warm air conditioners.

This type of air conditioner allows us to cool down in the summer, delivering heat from the interior to the outside and lowering the temperature indoors. In winter, the heat from the outside is transported to the interior to achieve the effect of increasing the indoor temperature. The so-called single-cooling air conditioner is an air conditioner that only cools or heats.

For example, in Sichuan and even most of the southern regions, the four seasons are distinct, the temperature in winter is relatively low, the lowest temperature is between 0 10, and the outdoor temperature is too low will cause the air conditioner to not work normally, because the outdoor temperature is already very low, we also need to make the outdoor temperature lower (the outdoor unit of the air conditioner in winter is to absorb outdoor heat indoors.

Our air conditioner is prone to frost, and the air conditioner cannot be frosted automatically, so the heating effect of the air conditioner will be greatly reduced, or even no heating. This is not because the air conditioner is of poor quality, but because it is a common problem caused by natural phenomena.

At present, the most common heating method in the south should be air conditioning heating, due to the coexistence of air conditioning and heating, for most southerners, it saves a heating cost, so many people will have such a question: "I have installed air conditioning in my home, is it necessary to install floor heating?" ”

It is true that the air conditioner has a good cooling effect and also has a certain heating function, but in fact, the user experience of the air conditioner when heating is far from that of floor heating.

At present, most air conditioners on the market will add electric auxiliary heating, which increases power consumption. At the same time, when the outdoor temperature is too low in winter, the outdoor unit of the air conditioner is prone to frost, and the defrosting process is not only time-consuming but also consumes electricity.

Air conditioning belongs to thermal convection heating, which is to drive the hot air circulation of the air in the whole room by heating the air above, because it has been blowing hot air on the head, it will make people dizzy and hot, and it is easy to stir up indoor dust or textile fibers, etc., and it will affect the health of the human respiratory tract in such an environment for a long time. At the same time, the hot air circulates indoors for a long time, which is easy to take away indoor moisture and human body moisture, and people will feel dry and bored.

Compressor operation, defrosting process, convection air circulation, and even the sound of water droplets can all affect the lives of some users. Especially in modern people's work and life, the pressure is high, and the sound of water droplets alone can torment people who can't sleep all night. Although most brands of air conditioners have different degrees of sound insulation and sound insulation design, after long-term use, the sound insulation and sound insulation effect will gradually decline.

The floor heating is to use the whole ground as a radiator, through different heat media, evenly heat the whole ground to achieve the purpose of heating, in terms of comfort is far better than air conditioning, and about energy saving, the floor heating effect of different heating sources is not the same, but the whole is better than air conditioning. Therefore, although the cooling effect of air conditioning is very good, in the case of conditions, it is best to choose floor heating for heating.

With the improvement of people's living standards, the use rate of floor heating is also increasing year by year, in addition to the widespread use of floor heating in the northern region of China, the relatively mild temperature of the south has gradually joined the army of floor heating; As early as 2016, the overall growth of the floor heating retail market in the south was 15%, except for a few southern provinces and regions such as South China, Shanghai, Yunnan, etc., floor heating accounted for more than 90% of the share, and most other southern provincial markets, floor heating accounted for about 60% of the new house heating system. It can be seen that floor heating as the best heating method is being recognized by more and more people.

**Air conditioning in the refrigeration technology is not comparable to other products, but heating or heating is more comfortable, because the heat is rising, so you can choose **air conditioning and heating are installed if your conditions permit, I don't know if you are in that city, if you are in Wuhan, you can go to Junda Guanghua to see.

Conditionally, it is recommended to install heating or underfloor heating:

1. The heating effect of air conditioning in winter will be affected by the outdoor temperature, and the lower the outdoor temperature in winter, the worse the indoor effect;

2. In winter, the air conditioner will have a defrosting phenomenon, and the defrosting process will cause large fluctuations in indoor temperature;

3. Air conditioning heating will cause the air to be drier, and the indoor temperature will drop rapidly when the air conditioner is turned off;

4. The indoor temperature of heating or floor heating is relatively uniform, and the comfort is higher.

**If the air conditioner is multi-linked, it is generally heated. The air duct machine is single cooling, and it is generally necessary to add heating, if needed.

It is recommended to use multi-online ** air conditioner, which has good stability. Think about it in the future, if you repair it, it will ruin your renovation.

Need. 1. The warm air should be lighter, it should go up, the air outlet of the air conditioner is originally on the ceiling, the warm air can not sink, no matter how long you stay in the house, the socks are always cold, medically speaking: cold starts from the feet, the normal heat cycle in the human body is from the feet to the head, think about it, if you can be comfortable from head to toe?

2. As long as the air conditioner is on, the window cannot be opened, if the window is opened, it is equivalent to not turning on the air conditioner, and the indoor air quality is poor and very stuffy. Coupled with an unworked tuyere in the fall, a lot of dust and bacteria were blown out, which could easily cause upper respiratory tract infections. Some friends come out of the air-conditioned room and find that their faces are flushed, dizzy, chest tightness, and discomfort, all of which are caused by the above two reasons.

3. Floor heating is different, it is the warm air that rises from the underground heating, and the warm air rises to the height of the meter, which is the most suitable for the human body, and the window can be opened appropriately will not affect the use effect, which not only warms the home but also keeps the indoor air fresh. If there are children in the house, you can also let him crawl around on the ground wantonly, which will not hinder him from finding his own happiness and the mystery of the whole house!

4. Relatively speaking, air conditioning energy is a high-consumption product, with high usage costs and large average volume.

5. Air conditioning is easy to make some people suffer from air conditioning disease, mainly when the air conditioner blows, it stirs the air, so that some flying dust and bacteria on the ground and the wall are stirred into the Zenhu air, and then let people breathe in it and cause respiratory diseases.

6. Air conditioners are prone to the situation that it is difficult to meet the appropriate temperature of people, such as a large space and other reasons.
