In the cold winter, sometimes families have to use air conditioners to heat up, but when using air conditioners, many netizens find that they don't feel hot in a 30°C air-conditioned room in winter, and the temperature of 30°C in summer will be heated into dogs.
Is the 30°C in the air-conditioned house different from the 30°C outside, in fact, it is not, the main reason is that the temperature is not adjusted.
Great invention
For us in the cold winter, air conditioning is one of the greatest inventions, and it can improve the comfort of our lives.
As an indispensable household equipment for people nowadays, air conditioning provides people with cooling in summer and heating in winter, so that now more and more people's lives are inseparable from it.
As everyone knows, air conditioning has a history of thousands of years, and around 1700 BC, the Babylonians have invented an ancient air conditioning system.
Using the principle that hot air rises and cold air falls, the Babylonian draws the hot air out through a wind pole installed on the roof, allowing the natural wind from outside to pass through the cool water and blow into the room, making the people inside feel cool.
Our ancient emperor also had a unique way to cool down, he would use a lot of manpower and material resources to transport the ice from the north to the national capital, store it in the basement, and take it to the room to cool down in summer.
In the costume TV series "The Legend of Zhen Huan", in order to show filial piety, as long as it is summer, the big fat orange will let his subordinates take out the ice from the ice cellar, put it in a ceramic tank, and use the physical cooling method.
The royal family can use ice to cool down, and for ordinary people, although there is nothing they can do, they can use swimming, or use a fan to cool down.
In 1902, with the development of the times, the first modern air conditioner was born, and Willy Carrier, who invented the air conditioner, is also known as the father of air conditioning.
Willis Carrier didn't want to invent air conditioning at first, but to improve the printing press in his factory, so that in the summer, color printing would always fail due to wet weather, which would affect sales.
Perhaps even he didn't expect that Willy Carrier discovered a new continent, opened up a new field, and directly manufactured the first air conditioner.
In order to be able to cool down the temperature of the factory, Willis Carrier soon brought the initial improvement hair dryer to the factory, but due to the high humidity of the blowing air, it did not meet the requirements of the printing house.
Until Willis Carrier was waiting for the train at the train station, he accidentally saw the train spewing water vapor in order to cool down when it entered the station, so he quickly ran back to the studio, and added a condensing device on the basis of the original air conditioner, and since then, the first air conditioner in the real sense was born.
This feat directly changed the way people finally used artificial refrigeration to adjust the indoor temperature, and he did not expect that this feat directly made the tertiary industry flourish.
In 1928, the company launched the first generation of household air conditioners, but due to the large volume of manufacturing, as well as the high price, air conditioning has not been popularized in major families, and later with the development of technology, the company created smaller and smaller air conditioners, and later, air conditioning began to really enter the hearts of ordinary people.
It can be said that every household now has air conditioning, but with the popularization of air conditioning, some problems have appeared, such as not getting hot in winter, slow cool breeze in summer, and slow start of air conditioning in winter......
I have to say that many of the above situations have been encountered in many homes, but the air conditioner that has been used for many years still defaults to the problem of air conditioning.
For example, the air conditioner in winter does heat up slower than in summer, but if you turn on the air conditioner for a long time, you still feel that it is not too warm, and it will not be like heating, and it will be a breath when you enter the room, but then again, although the air-conditioned room does not heat up in a large area, there is always a small piece that is warm.
But if you really drive it for a long time, you still can't get hot, if you adjust the temperature to 30 degrees, the feeling is still average, and you can't get such a temperature at all, what is going on?
In fact, many netizens do not know so much about air conditioners, and if they are operated correctly, they will definitely be able to achieve the desired temperature.
First of all, it should be known that the direction of the wind blowing in the air conditioner in winter and summer is also different, in summer we are using the air conditioner, in order to cater to the airflow, the wind deflector is used upwards to avoid the cold air blowing directly on the face, and in winter, because the hot air goes up, so the hot air blown out of the air naturally goes up.
If you want the room to be warm, you should first close the roof in time, otherwise even the hot air will run away, in addition, if the air conditioning wind shield is facing up, the hot air is concentrated on the ceiling, if there is no high height, you must feel the heat of the air conditioner.
In this way, if you want to feel the temperature of the air conditioner in winter, you can turn the wind deflector of the air conditioner downwards so that the heat will come over.
If you can't feel the temperature of the air conditioner in winter, it has a lot to do with the large temperature difference.
The working principle of air conditioning is to absorb heat from the low temperature end, and transport the heat to the high temperature cushion end, due to the large temperature difference, which directly leads to the low efficiency of the air conditioner, and there is a low heat content of the outdoor high temperature end, want to absorb heat from here, the difficulty is naturally much higher than in summer.
In addition to the large indoor temperature difference, there is also a point that the power of electrical appliances is low, which is also very obvious in summer, if you use other high-power household appliances when using air conditioners, resulting in a long time to be able to use the room to become warm.
And there is another reason why the air conditioner does not feel warm, and another is the comfort of the air conditioner.
Friends in the north know that when the indoor temperature is the same, the room heated by the floor heating or radiator is warmer than the air-conditioned room, and this reason has a lot to do with the wind shield of the air conditioner and the direction of the wind.
The air conditioner is hung on the ceiling, coupled with the upward movement of the hot air of the air conditioner, and people's needs are precisely the head is afraid of heat, the feet are afraid of cold, this series of reasons will lead to the same temperature, the use of air conditioning to heat the room, will feel more comfortable.
And the temperature of the air conditioner is not just a number, set 30 degrees not to mention whether it can be reached, but I don't know the advice given by experts, as long as it is adjusted to between 20 °C and 22 °C, the indoor temperature can be optimal, and it is also suitable for the human body temperature.
In fact, the air conditioner must be cleaned in time, the filter screen must be taken out for cleaning, and the mode must be adjusted when the heater is turned on.
The tuyere is facing down, cleaned in time, the temperature is moderate, coupled with the good indoor heating effect, several conditions add up, and the air conditioner in winter can also reach the corresponding temperature and have a warm winter.
