How to keep the room cool without an air-conditioning fan?

How to effectively cool the room in summer without air conditioning? In the absence of air conditioning in summer, how can we effectively cool the room? Summer has arrived. It is very hot at this time, and it is too hot in summer. For example, when the temperature reaches 40 degrees Celsius, many people often suffer from heatstroke, so it is necessary to cool down. The following describes how to effectively cool rooms without air conditioning in summer and related information. How to effectively cool the room in summer without air conditioning? 1. Indoor air circulation cleans the whole room, making the layout in the room as clean and bright as possible, reducing the accumulation of chores, which is conducive to the circulation of indoor space. In addition, indoor and outdoor ventilation should also pay attention to the time period. Due to the high outdoor temperature in summer, if the indoor doors and windows are wide open, the outside sunlight and heat will directly attack the room, resulting in a rapid increase in indoor temperature. Therefore, try to open the doors and windows for ventilation when it is cool in the morning and evening. 2. Replace it with furniture with simple shape and cool color. Then, furniture is also a factor that affects room temperature. Furniture such as fabrics and leather can make people feel stuffy in summer. If you want to make your home cooler, you might as well change some wrought iron, rattan and glass furniture with simple shapes and cold colors. It not only makes people feel cool visually and tactilely, but also absorbs some indoor heat to help cool down. 3. The choice of sleeping mat It is a traditional way to cool down by laying a sleeping mat on the bed. The optional materials of summer sleeping mat and pillow are grass, flax, bamboo fiber and so on. It is easy to sweat in summer. Bedroom bedding should try to choose those natural, breathable and environmentally friendly textiles, such as pure cotton, flax, bamboo fiber, modal and other materials, which have strong hygroscopicity, comfortable and soft feel and can keep refreshing after long-term use. Stick insulating paper on the window in the western sun. Generally speaking, the room temperature of the west sun is high in the afternoon, and it can be said that it is sultry in summer. If you turn on the air conditioner from the afternoon sun time, the accumulated electricity bill in a summer is quite amazing! At present, there is a kind of heat insulation paper on the market, which can block ultraviolet rays and thermal radiation. Sticking it on the window surface of the western window can reduce the indoor temperature by 2 to 3 degrees. After installation, it is estimated that it can save 20% of the air-conditioning electricity bill. 5. Install heat insulation curtain. Thermal insulation curtains can effectively block heat and adjust light. Conditional families can install an extra layer of thermal insulation curtains on their windows. Draw curtains in summer to prevent outside heat from entering the room. Curtains can effectively resist heat, and white curtains or shutters can block 40.50% of the heat in the sun; Thick curtains or bamboo curtains can block 60.80% of the heat, although it will affect the line of sight. Most importantly, a room with dark light will feel colder than the actual temperature after curtains are installed. 6, light color makes cool. To make your residence look cool, you can use white as the main color. White can not only increase the sense of space, but also create a bright and quiet atmosphere, making people emotionally stable. In addition, consciously adding a little cool color can also make people feel carefree visually. It is the most economical and effective way to buy some cool decorations in summer, such as changing a white lampshade for the desk lamp and putting a set of ice-blue bathing utensils in the bathroom. 7. Avoid using multiple electrical appliances at the same time. Many electrical appliances will generate heat, such as refrigerators and electric lights. If you are still using the air conditioner, you'd better not put large electrical appliances such as TV and computer next to the air conditioner. Because the heat emitted by these appliances will cause the air conditioner to run for a long time. These appliances are the key to make your house hot. So people in the industry suggest turning them off unless you really need them. 8. Replace the cold light energy-saving lamp with low wattage. If the indoor light is too bright, especially some families choose warm lights, it will make people feel hot and irritable indoors. On the premise of ensuring the necessary reading brightness, local lighting desk lamps and floor lamps are used to replace the warm lamps with low wattage electroluminescence. Soft lighting can bring a cool feeling in summer and save electricity. How to effectively cool the room in summer without air conditioning 2 1. Wear sunscreen curtains: When the weather is hot in summer, you can consider wearing sunscreen curtains to isolate strong ultraviolet radiation and prevent the room from being exposed to the sun. Open the doors and windows to ventilate when you come back. This kind of curtain can effectively resist heat. White curtains or blinds can block 40-50% of the heat in the sun; Thick curtains or bamboo curtains can block 60-80% of the heat, although it will affect the line of sight. 2. Use a fan and water evaporation: If you want to cool the room quickly without air conditioning, you can make your own air conditioning. That is, using fans and water evaporation to cool down indoors. Method: Take a basin of cold water, or add ice cubes, and then blow a fan against the cold water to let the wind blow through the cold water and then blow it out, which can help the room to cool down quickly. Or wipe the floor indoors with a wet mop, and turn on the ceiling fan to evaporate the moisture on the ground to absorb heat. 3. Pave a new mat: Paving a mat on the bed is a traditional way to cool down. The optional materials of summer sleeping mat and pillow are grass, flax, bamboo fiber and so on. It is easy to sweat in summer. Bedroom bedding should try to choose those natural, breathable and environmentally friendly textiles, such as pure cotton, flax, bamboo fiber, modal and other materials, which have strong hygroscopicity, comfortable and soft feel and can keep refreshing after long-term use. 4. Stick insulating paper on the sunny window: In summer, in the sunny house, the room temperature will be very high in the afternoon. In order to save electricity, you might as well buy a piece of insulation paper in the market and stick it on the window surface exposed to the sun. It can not only block ultraviolet rays and thermal radiation, but also reduce the indoor temperature by 2 to 3 degrees. How to effectively cool the room in summer without air conditioning 3 1. How to escape the heat in summer? 1. Hang wet curtains or towels. When the outdoor air is dry, you can soak the curtains at home or hang a wet towel by the window. After the water evaporates, the wind blowing into the house will cool down, so try to choose the color of the curtains. Light color, strong reflectivity, can block nearly half of the heat out of the window. 2. Put the ice in front of the fan. When the room is too hot, the wind of the electric fan is very hot, very hot, not hot at all. Try to put a big bowl of ice in front of the electric fan. As ice melts and evaporates, it will explode. The wind can be much cooler. 3. Green Plants If you live on the roof of a building, you might as well use greening to reduce the heat absorbed by the roof from the sun, thus effectively reducing the indoor temperature. Under the scorching sun, planting plants can even reduce the temperature on the roof surface and the temperature difference between the roof and plants. It reaches 20 degrees. Even if the family doesn't live on the top floor, they can plant some plants in the house to purify the air in the house. At the same time, they can block the sunlight in the house and cool the house in summer. 4. Putting water indoors and putting a pot of clean water at home will help to adjust the indoor temperature. In addition, it can increase the humidity in the air and reduce the phenomenon of heat. In addition, the air conditioner can remove some moisture in the air during the refrigeration process and stay in the air for a long time. Feeling a little dry, you can put a pot of water in the air conditioner to increase the air humidity. 5. Don't use multiple devices at the same time. Electrical appliances will heat up during use. These appliances are also the key to make your house hot. So in order to avoid using multiple appliances at the same time, it is best not to put everyone's electricity together. For example, it is not recommended to put the refrigerator next to the TV, because the heat generated by the TV when using the refrigerator will cause the refrigerator to run for a long time. Second, what are the skills to buy air conditioners in summer? China has a vast territory, and the climate in many places is very different, so there are some differences in the demand for air conditioning in different regions and families. Therefore, you should pay attention to your own needs when purchasing air conditioners. If you really don't know how to buy it, stick to the principle of buying a large air conditioner instead of a small air conditioner, because different air conditioners have different energy-saving effects, and the energy efficiency ratio of air conditioners = refrigeration capacity ÷ refrigeration power. According to the formula, under the same figure, the air conditioner with high energy efficiency ratio is more energy efficient than the air conditioner with low energy efficiency ratio. Generally speaking, the cooling effect of air conditioning is higher than that of heating, and the applicable area of air conditioning in winter is smaller than that in summer. Therefore, when purchasing air conditioners, the heating index of air conditioners shall prevail, and it is best to choose air conditioners according to the applicable area in winter. According to the size of the room area, the sealing and thermal insulation conditions of the room, the floor, orientation, height and other factors, the size of the air conditioner can be calculated. For cooling, the cooling capacity per square meter can be 130- 180W. If air conditioning is needed for heating in winter, it can be calculated at per square meter 150-200W, and the cooling capacity is 2500w W, so try to buy it. The indoor unit of wall-mounted air conditioner is installed on the wall, and the energy efficiency ratio of cabinet unit is poor. 3. What should I pay attention to when using air conditioner in summer? 1. The air conditioner is always on and off. Unlike other electrical appliances, air conditioners can work continuously for a long time, and there is no need to shut down and rest in the middle. The longer it takes, the less electricity it uses, and the more frequently it is switched on and off, the more electricity it uses. According to the normal use of the main components of the air conditioner, the service life of the compressor is about 72,000 hours, that is, 3,000 days, which is equivalent to 8 years of working time, that is, continuous working time. If useless time is eliminated, serious accidents will not happen. Theoretically, it can be used for more than 30 years, but with aging, it will take at least 15 years. In order to be cool in summer, many people can't wait to turn on the air conditioner as soon as they enter the room, and even stand in front of the air conditioner to blow air. This is a very dangerous behavior, because when we first entered the house, we were all sweaty and the sweat pores on our skin were open. If we catch a cold suddenly, the sweat pores will shrink and the heat in our body can't be discharged, then we are likely to catch a cold and even have serious facial paralysis. When we use the air conditioner, we can blow the air outlet of the air conditioner upward. Because cold air circulates downward, hot air circulates upward. In this way, hot and cold air circulates quickly and evenly, which makes people feel comfortable and the indoor temperature drops the fastest. Don't close the window before turning on the air conditioner. Turn on the air conditioner before closing the window. Many people have made this mistake and are always afraid that air conditioning will waste resources. Closing the rear window makes it easier to discharge harmful gases such as bacteria and mites from the air conditioner indoors, which will make the indoor air cleaner. Don't turn on the indoor air conditioner for too long. It is best to open the window for ventilation in about 3 hours, reduce the indoor toxic gas concentration, and inject fresh air regularly. For friends who don't have air conditioning in the bedroom, if they feel too hot at night, they can choose the above methods to cool down in summer, so that their families can sleep comfortably. In addition, if you want to buy an air conditioner, you should also pay attention to the purchase method and choose an air conditioner with the right power according to the size of your house.
