500-word composition on air conditioning

Article 1: air conditioning

I am an air conditioner. I'm dressed in white, as white as winter snow, and I look square. The most prominent thing is my mouth, which is big and long with a narrow tongue in the middle.

I am also a treasure, and everyone wants it, because my long mouth has "magic power" in winter. When people get cold, they start to "exert their strength" when they get home. Warm air comes out of my mouth, making the room warm as spring. In summer, people run in the hot sun, and sweat flows on their bodies like running water from a stream. When I got home, I began to "exert myself" to spit out the cold in my mouth and make the room cool as autumn. I can't change the time. When I can change the "season", the place with me must be a "land of feng shui" with warm winter and cool summer and pleasant climate.

Once, the young master was playing football in the community, and the sweat on his head was bigger than that of soybeans. He blushed like a ripe red apple and opened me at once. "Di" I started, full horsepower, cold wind blowing in my mouth. It was just a cold wind. The little host shouted coolly: "Ah! Ah! How cool! That's right. It's so comfortable The air conditioner is so powerful! " After listening to the young master's praise, I couldn't help feeling proud and beginning to feel complacent. The little master's sweat gradually dried up and his face was no longer red. Then he picked up the remote control and let me rest. I blew a breeze casually to keep cool without getting sick, but it was a very difficult task! But I did it for my career-to make people happy. I've been doing my duty.

This is me, an air conditioner that can change seasons and make people happy.

Chapter two: Dialogue between air conditioner and cattail leaf fan.

Air conditioners and cattail fans are used in summer, and people will use them when the weather is very hot.

One day after dinner, the hostess of a family was using a cattail fan to fan the wind, and the man of that family was enjoying it in his room with the air conditioner on. They all have their own ways. At this time, the air conditioner smiled and said, "You are really useless. When people are hot, they have to fan themselves to cool down, and I just need the owner to press the button, and I will bring coolness to the owner. You see how powerful I am! " Pufan was not angry, but said modestly, "Air conditioning is certainly good for you, but you will also bring air conditioning disease to people!" " Although I am inconvenient, I will not bring diseases to mankind! When people stay in the room with you for a while, then go out of the room to the scorching sun, and then go back to the room, it is easy to get air conditioning disease when walking back and forth. As long as you have air-conditioning disease, you will catch a cold every day, which is difficult to treat. And I'm cheap, and I won't let humans get strange diseases. "

The air conditioner seemed to understand what Pu Fan said and said to Pu Fan, "I take back what I said just now, and I apologize to you. If there is a power outage, you will naturally be indispensable. "

Pupan and air conditioning have reconciled. Pu Fan said, "We are friends and we shouldn't haggle over every ounce. We should see our own shortcomings and learn from each other in the future. "

Since then, air conditioner and cattail leaf fan have become best friends.

Article 3: I am an "air conditioner"

I am like the air conditioner at home. Blow "cold air" for a while and "hot air" for a while. Take the following as an example.

When I was in the first grade, my mother would give me some homework every night. Once, because I wanted to play quickly, I just wrote a letter and went to play. At this moment, I am not like an air conditioner that blows heating. Not only do I feel warm in my heart, but the air outside is also warm. At this time, I just think you are heating and air conditioning. The next day, my mother began to correct homework. After she finished correcting her oral calculation book. Mom seems to have learned the "widespread indignation and discontent" in "Ma Jing Warrior"! Shouting angrily: "Look, look! Ah! This is your homework! ! How many of the forty questions are correct? " He gave me a slap in the face. "Copy a question one hundred times! Go to sleep after copying! " Say that finish and listen to "bang!" Mom slammed the door. At this time, I seem to be walking in the ice and snow, and I still "blow the cool breeze" from time to time. Why did you hurry at that time?

You all say, am I hot and cold like an air conditioner?

Chapter 4: Turn on the air conditioner

In the hot summer, we kept asking the teacher in the dormitory, "Teacher, if there are eyes in the sky, will you turn on the air conditioner once?" It seems that our honesty has really touched the sky. The teacher turned on the air conditioner yesterday, so we must enjoy it today.

After lunch at noon, I walked into the corridor of the dormitory, which was full of hot air. I'm sweating all over, I'm wet and I smell of sweat. When I walked to the door of the dormitory, a little coolness floated out from the door. I think I must have turned on the air conditioner, otherwise it wouldn't be so cold.

I went to my room and asked Extraordinary, "Is the air conditioner on?" Nodding exceptionally, I ran to the air conditioner and reached out to feel the cool breeze blowing. "Oh, how cool!" "I can't help but exclaim. And Fan Ao was very dissatisfied. "Why can't I blow this? "Strong, lift the blade!" I walked under the air conditioner and lifted the blades with my hands. "Well, that's cool!" Fan Ao also expressed admiration.

We lay in bed, the wind gently blowing us, and gradually entered a sweet dream.

Chapter 5: Earth Air Conditioning

The weather is getting hotter and hotter. I looked up out of the window and saw the scorching sun burning the earth mercilessly, and the earth was smoked straight. Pedestrians on the road scurried around without masks, leaning in the shade. Several people sat under a small tree in the sun and fanned their fans impatiently.

It's 2030. Due to the greenhouse effect caused by air pollution and the attack of El Ni? o phenomenon, the global temperature is warming, the ice layer in the North and South poles is melting, the sea level is rising, and coastal cities are threatened ... This has become an important issue for countries to study and solve.

I'm studying a chemical that changes from a liquid to a transparent film when it enters the air. It not only has the function of adjusting temperature, but also has excellent high temperature and cold resistance. It can not only absorb all kinds of rays, but also adjust the contents of oxygen and carbon dioxide in the air. Soon after, the research was successful, and I named it "Earth Protector 1".

Factories in various countries began to mass-produce "Earth Protector I", and since then, the global temperature has begun to normalize.

Article 6: Self-report of air conditioner

I am a split air conditioner. He is short and fat, and his figure ratio is similar to my little master's pencil case. He wears a white striped shirt and likes to stand on high places. I naturally like to stick my big square head out of the house, which is the habit of our air conditioners.

My little master likes me very much and puts me in his little room. We always care about each other. On a hot summer day, as long as I stand on tiptoe and press my fingers, I will emit air-conditioning or air-conditioning from my body; In the cold winter, I will give off hot air. Young master will often wipe the dust off my body with a clean dry towel. Whenever I get sick, my young master always sends me to the hospital for examination in time.

Young master is always proud of having a friend like me who is warm in winter and cool in summer. I am also very happy to be welcomed by people.

Do you know that?/You know what? Do you know that?/You know what? I can not only keep warm and cool down, but also do good deeds! For example, take a breath! Just when the indoor air is poor or very poor, close the empty door, I will inhale stale air and spit out fresh air, so that the air in a room will always be fresh.

Chapter 7: Air Conditioning in Summer

In summer, the cicadas in the trees are too hot to call out, and the ground is also very hot. People cover their heads with towels and try their best to avoid the vicious sunshine.

The host crossed his legs, smoked a cigarette, leaned on the cane chair and blew the wind leisurely under the fan. The wind blown by the electric fan is really comfortable. It shook its head proudly like a rattle. He glanced sideways at the cattail leaf fan and saw that it was left out in the dark corner, as happy as eating honey. This thing is really ungrateful, it thought. With you? ! Don't try to ascend my throne, no one can match me! It wanted to satirize the cattail leaf fan deliberately, so it said contemptuously, "Hey, you outdated things are useless, get out!" " Stay in a cool place! What do you mean? I've been here, trying to drag me back "

Pufan didn't get angry after listening to the fans. It said calmly, "Dude, I can still exist, so I must have my own use!" " Don't underestimate me! "

"What? Did I hear you wrong? Are you ... are you useful? God, this world is wonderful, and there are many strange things! "

Pufan sighed and said nothing.

But this craze didn't last long. One day, the host moved in a monster, which scared the fans. Later, I learned from the conversation between the owner and others that this behemoth was originally called air conditioning. Since having this air conditioner, the fan has been left out in the cold and moved to the corner by the owner. Fan and Pufan, look at me, I look at you, I cry and hug. The fans blushed and said, "I'm sorry, I really shouldn't say that about you!" " Pufan shook his head vigorously and said, "Never mind, I don't mind. "They are in the same boat!

The air conditioner blows cool air, which makes the owner intoxicated and want to sleep. The air conditioner shook its mouth and proudly said to the fan and the cattail leaf fan, "You two really can't keep up with the pace of technology." However, before the words were finished, the power went out. I still want to blow the air conditioner, but I can't move with my mouth open. The host was so hot that he was sweating all over and was anxious to walk around the room. He scratched his head, glanced around the room, patted his head, and remembered! He ran to the corner of the room, took out the dusty cattail leaf fan, dusted it and fanned it hard. After watching it, the fans muttered guiltily, "Yes! Everything in the past has its own uses.

Chapter 8: Future Air Conditioning

Nowadays, air conditioning takes up a lot of space and is often the privilege of parents. How can children enjoy the taste of "cold world"? With the "oblique angle" air conditioner, there will be no problem.

"Oblique angle" air conditioner is a flat and very thin air conditioner. This kind of plastic is soft, it won't hurt your head, it's not easy to be damaged, and it's light. His color is not fixed, but changes according to the environment of the four seasons, such as turning green in spring and blue in summer, which adds a little comfort to the house.

To say that the structure of this kind of air conditioner is very complicated is to compress the functions of ordinary air conditioners and then put them in. If you think it is still powered by electricity, you are all wet. This high-tech air conditioner uses solar energy. If there is no sunshine in this area, his assistant, the electric search plane, will help her find the sunshine, transmit it and convert it into electricity, which is very convenient.

As this kind of air conditioner is very thin, it can be installed as long as it is stuck somewhere. This kind of air conditioner is best installed in the middle of the room, with a ventilator inside. The changing airflow wind and the wind generated by the air conditioner are mixed together and blown to every room, so that every room has a cool feeling. Because the changing airflow wind will change the hot air that stays into the fast-moving cold air, which will save some electricity.

Its magical function goes far beyond these, and it can also blow out strange winds. Because it is equipped with human body sensor, when you are bored, it will blow out exciting wind, as if to take you to the "adventure island"; When you can't sleep, it will use soft wind to urge you to sleep, and when you fall asleep, it will automatically shut down.

The operation method of this air conditioner is very simple. Give an order to the microphone and the air conditioner will "do it".

It's not enough to enjoy this air conditioner now. I'll contact you when I grow up!

Article 9: I want to invent air-conditioned clothes.

Today, the weather is very hot and sweaty. Therefore, I invented an air-conditioning suit with special functions.

The appearance of air-conditioned clothes is no different from ordinary clothes, but it has great functions. You must ask, "What function does it have?" Let me explain it to you one by one! Its first function is very practical. You must feel very hot in summer! Never mind, there are air-conditioned clothes! You will feel very cold in winter, right? Air-conditioned clothes will help you. You may wonder how the air-conditioning suit knows the temperature. The secret is in the button of the air-conditioning suit. The button of the air-conditioning suit is a thermometer that can measure the temperature. Once the thermometer senses that the temperature has changed, it will automatically send instructions to the air-conditioned clothes to make the temperature of the clothes suitable for the human body.

In addition, the second feature of air-conditioned clothes is that they will be automatically dry-cleaned. Those who are tired from work have no time to wash clothes. As long as you take off your air-conditioned suit at work, it will be dry-cleaned automatically. In this way, it saves time for those who are busy with work to wash clothes. If you are tired from work, there is a massager in the air-conditioned suit, which can make you get rid of the fatigue of the day and relax your whole body. If you feel bored after working for a long time, you can also listen to the music released from the air-conditioned suit to relax.

Ah! I really hope that in the hot summer, I can enjoy working while working. How nice it would be!
