1. When did the earliest models of air conditioners appear? Icon Ancient Egypt Icon Ancient Roman The correct answer is answer A: According to research by archaeologists and historians, the most primitive model of air conditioners appeared from ancient Egypt. To cool the indoor air and avoid the hot and dry desert climate, the ancient Egyptians hung bundles of water-soaked reeds in the windows. When the wind blows through the window, it will bring water vapor into the house. Another way of cooling the ancient Romans was that they surrounded the walls of the house with plumbing, when the water circulated, it would cool the house. Water cooling was also adopted by the medieval Persians. Their system includes wind towers and water tanks that help cool the indoor air. 2. Who came up with the first idea for an air-cooling system? Icon Michael Faraday Icon John Gorrie Icon Benjamin Franklin The correct answer is answer B: Scottish physician John Gorrie (1803-1855) Scottish physician John Gorrie (1803-1855), who gave the first idea of ​​the air-cooling system. Although the model and ideas above were never realized, in 1851, Gorrie was still awarded a patent for a machine that made ice. 3. Who invented the model of air cooling by adding salt to water as it evaporates? Icon Cornelis Drebble Icon Michael Faraday Icon Benjamin Franklin The correct answer is answer A: Beginning with the inventor Cornelis Drebble (1572-1633), he invented a model for cooling the air by adding salt to water as it evaporates. They were introduced to the then king of England, James I, but were not taken seriously. In 1758, the governor of Pennsylvania, Benjamin Franklin (1785-1788) and Professor of Chemistry John Hadley (1731-1764) at Cambridge University experimented and discovered the principle of reducing heat from evaporation. This was an important invention that laid the foundation for later air conditioners. Both Franklin and Hadley realized that the evaporation of a liquid such as alcohol or ether could lower the temperature of an object below the freezing point of water. Both men successfully experimented with evaporation to reduce the temperature of a mercury thermometer tube from 18 degrees Celsius to minus 14 degrees Celsius. By 1820, the British chemist Michael Faraday (1791-1867) made it. successfully experimented with compression and liquefaction of ammonia gas. During his experiments, he realized that evaporating liquid ammonia could cool the surrounding air, and this was one of the premise for later air conditioners. 4. Who first invented the modern air conditioner? Icon Willis Carrier Icon John Gorrie Icon Benjamin Franklin The correct answer is answer A: In 1902, Willis Carrier (1875-1950) invented a model of the air conditioner while working for the Buffalo Forge mechanical company. Willis Carrier was born in New England state (USA), from a young age, she was smart and bright. After graduating from Cornell University, Mr. Carrier worked in a heat-resistant suit. His research saves the company $40,000 per year. With this invention, Carrier is known as the father of the modern air conditioner model that we are using. However, Carrier’s air conditioning system is very large, noisy, extremely expensive and very dangerous because it uses the toxic chemical ammonia to cool the air. In 1911, Carrier continued to introduce “refrigerant formulations with reasonable humidity ratio”, this method of refrigeration is still used in some areas of the refrigeration industry. 5. Where was the Willis Carrier air conditioning system first used? Icon A movie theater Icon A printing factory Icon On the bus The correct answer is B: Willis Carrier’s air conditioning system is used in a printing factory. This system helps control the temperature and also keeps the humidity in the plant. Carrier’s principle of humidifying the air is quite simple, instead of pushing air through the heating tube, the air flowing through the tube is cooled by liquefied ammonia. 6. In what year was the Carrier-built air conditioning system first installed in a home in Minneapolis? Icon 1913 Icon 1914 Icon 1915 The correct answer is B: In 1914, a Carrier-built air conditioning system was installed for the first time in a house in Minneapolis. This machine is 2.1 meters high, 1.8 meters wide and nearly 7 meters long. But this machine has never been used because no one lives in the house. However, homeowners still have to spend more than 60,000 USD per year to maintain the entire house. 7. When was the first movie theater in the US equipped with air conditioning? Icon 1917 Icon 1918 Icon 1919 The correct answer is answer A: The household air conditioner has a height of 2.1 meters, a width of 1.8 meters and a length of nearly 7 meters. However, it has never been used because no one lives in the house but, the owner is a famous gambler who is rich and spends more than $60,000 annually on maintenance. From 1917 to 1930, the cinema was a place for people to enjoy the air cooled by air conditioning. The first movie theater in the US to be equipped with air conditioning was the New Empire Theater in Montgomery, Alabama in 1917. In that year, the Central Park Theater in Chicago also installed an air-conditioning system, which was enthusiastically received by customers. . Especially on summer days, the air conditioner is even more effective. In 1922, Carrier continued to make two breakthroughs in air conditioning. The first is that he replaces the toxic condenser ammonia with another, safer compound, dielene (dichlorethylene). 8. In 1969, the cooling system was fitted in Neil Armstrong’s spacesuit when performing a Moon walk, is it true or false? Icon It’s correct Icon Wrong The correct answer is answer A: In 1969, a cooling system was fitted in the spacesuits of Neil Armstrong and Buzz Aldrin to combat the conditions in space. These two astronauts wore them while on the Moon walk. Result Please work harder! point

An important thing to keep the house cool is to make sure the windows and doors are in positions that allow good air circulation.

In the hot season, air conditioners have become indispensable items in many families. However, for families with limited economic resources, it is not easy to buy a new air conditioner for 7-10 million VND. Therefore, many people choose to buy used air conditioners to save costs. Because the price of old air conditioners is usually only 30-50% of the price of new air conditioners of the same type. Old air conditioners are usually used domestic products that are liquidated, upgraded, or broken air conditioners that are bought, repaired, and sold in the market. Besides, there are also old air conditioners introduced as imported directly from Japan. Old air conditioner is the choice of many people. According to some owners of refrigeration equipment repair facilities in Hanoi, this year’s hot season, due to the impact of the Covid-19 epidemic, the economy is difficult, old air conditioners have become very popular. The old air conditioners of well-known brands such as Daikin, Panasonic, Toshiba, … with a capacity of 1.0-12.0 HP with prices ranging from 3-5 million VND / unit are interested by many customers. Currently, it is not difficult to find ads on Facebook, forums or groups selling these items, for only 3-5 million VND, for a model of air conditioner. In the hot season, on the “web market”, old air conditioners are advertised more and receive greater attention from customers, especially students, workers, and low-income people. Products for sale often come with a commitment to original, 80-90% new. Many refrigeration repair shops also took advantage of the increased demand to buy used air conditioners and imported this product. Many shop owners buy used air conditioners to repair and then resell. Customers who buy used air conditioners are free of charge for cleaning, installation of duplex gas pumps, insulation pipes, and drainage pipes to pay like new machines. Need to consider when choosing to buy used air conditioners Buying used air conditioners has the advantage of saving initial costs. But according to many experts, this is not necessarily an effective economical solution. Because buying old air conditioners has many potential risks and is also an economic problem that users need to consider carefully. If you are not careful, you will not save much, but will cause trouble, frustration, and quarrels in the house because the air conditioner does not work as expected. The monthly cost of using an old air conditioner will be much more expensive than a new one. Because old air conditioners often have low cooling efficiency because the engine has weakened after a long time of use. To create the desired coolness, the air conditioner needs to “work” more. As a result, electricity bills also increase a lot. Buying used air conditioners carries many risks. Moreover, old air conditioners have many potential risks such as spending a lot of money to repair, even being tricked into buying poor quality products. In fact, many refrigeration equipment repair facilities have not hesitated to enchant old, broken air conditioners and put them on the market and sell them at high prices. If the old air conditioner is renewed, clean the cover without interfering with the inside, then rest assured to use. But if you have touched the outdoor unit, the indoor unit of the machine or replaced the components, it has affected the life and performance of the machine. With the machine is too old, workers often use chemicals to bleach the plastic, when purchased, it looks very new but very quickly degrades. When buying these air conditioners, users think they can buy cheap goods, but in fact, they are expensive and break down quickly. Another problem is that old air conditioners often have a fault that is not cold or cold because of problems related to gas (less gas, gas leak, out of gas) or because it has a lot of dust that has not been cleaned carefully. In addition, old air conditioners often run not smoothly, or make loud noises, which may be due to excess gas, compressor problems or loose screws that are not checked and replaced. Another common mistake in old air conditioners is water leakage due to water leakage in the pipes from the cold unit; air conditioner jump atatat; the air conditioner is not running. According to electronics experts, in case you have to buy old air conditioners, you should buy them from relatives, friends or ask acquaintances who are knowledgeable about air conditioning techniques for advice to avoid being damaged or buying air conditioners. The old one is repaired and sold by a butt-cheek mechanic. Should buy products with popular brands and models, do not buy floating air conditioners. When buying, it is also necessary to carefully check the parts of the air conditioner such as the case, the hot unit, the cold unit, the gas conduction weld, etc. Should choose to buy the air conditioner at the electronics centers, reputable stores and have the mode. guarantee. If possible, buy a new air conditioner. On the market today, electronics supermarkets often launch many attractive incentives to attract customers. Accordingly, many 1- or 2-way air conditioners with a capacity of 9,000-12,000 BTU are being discounted to only 4-10 million VND per unit. New air conditioners are cheaper and cheaper, modern technology should save more electricity. Hanh Nguyen (Synthetic)

From only 4-5 million VND, consumers can own an air conditioner with many modern features. Many cheap air conditioner models impress with their ability to save electricity due to their own technology applications. Low-priced air conditioners are becoming the choice of many consumers. In particular, the models of air conditioners priced from 4-5 million VND are very attractive to customers. These models of air conditioners are not only cheap but also advertised as saving electricity. Despite the low price, these air conditioners are still diverse in models and designs, suitable for many different users. Not only domestic air conditioners such as Midea, Nagakawa but also foreign brands such as TCL, Electrolux, LG, … also have products in this segment. The market for air conditioners today is very rich. The feature of cheap air conditioner models is that they usually have a capacity of 9,000BTU, suitable for rooms with an area of ​​​​under 15m2. These are DC models (with cooling function only), not inverter series. For example, Casper 9000BTU 1-way air conditioner LC-09TL32 costs only 4.7 million VND; Casper 1-way air conditioner 9000 BTU LC-09TL32 priced at VND 4.6 million; Casper 1 HP LC-09TL32 air conditioner costs 4.79 million VND.

Midea one-way air conditioner model 9000BTU MSAFB-10CRN8 costs 4.49 million VND. Should I buy a cheap air conditioner? Many people still think “cheap is mine”, so they don’t buy cheap air conditioners. However, according to experts, the cheap air conditioner line also has its own advantages. The immediate advantage is that users can reduce a large amount of money to buy a machine. Cheap air conditioner models are mostly one-way air conditioners. One-way air conditioners usually cost half as much as two-way air conditioners. Meanwhile, the cooling feature of one-way air conditioners is no less than two-way air conditioners. Models of one-way air conditioners often have a radiator in the “hot block” made of mainly aluminum, anti-rust paint. The advantage of this material is its low cost and fast heat dissipation. These air conditioner models usually have a capacity of about 9000 BTU, suitable for small area rooms. Cheap air conditioners are mostly one-way air conditioners that only have cooling effect, suitable for hot summer weather. In places where the climate is hot all year round like the South or in the North where “winter is not cold”, buying a two-way air conditioner may not be necessary. Moreover, the use of one-way air conditioners will help save costs. In addition, cheap one-way air conditioners also have the advantage that during use, if damage occurs, the repair and replacement of components will be easier and less expensive. One problem that many people wonder is that cheap air conditioners are not equipped with inverter technology (air conditioners with energy-saving technology). However, according to experienced people, if the daily use time is less, it is not so important to have energy-saving inverter technology, while the price of inverter air conditioners will be 2-4 million VND more expensive than the average. with conventional air conditioners (without inverter technology). Inverter air conditioners often save electricity effectively with a continuous use time of 6-8 hours. If the time to use is less, you should choose to buy a one-way air conditioner. If you have the financial ability to buy high-end air conditioners at expensive prices, it will be very good. But with a tight financial situation, cheap, energy-saving air conditioners are still the best choice for many consumers. In fact, whether the air conditioner is good or bad depends not only on the air conditioner, but also greatly depends on the installer’s technique and the consumer’s usage. Therefore, when choosing a cheap air conditioner, consumers need to pay attention to choose to buy genuine quality air conditioners, with a professional warranty system. Buyers also need to refer to the power consumption parameters on the air conditioner product label. At the same time, customers should also find products that are suitable for their finances, installation conditions and usage needs.

Some electric supermarkets display air-conditioning fans at the entrance to attract customers Translation Covd-19 has significantly affected the consumption of electrical appliances in general and air-conditioning fans in particular. Therefore, right from the beginning of the year, electronics supermarkets simultaneously launched attractive promotions, but the purchasing power has decreased significantly. Therefore, electronics experts note, when buying an air conditioner fan should pay attention to the operating time of the product. For display samples, due to being turned on continuously for a long time with maximum capacity for customers to check and test products, so the durability of the product is also significantly reduced. Customers should consider when choosing the air-con fans with strong discounts because cheap prices sometimes come with unsatisfactory quality, need to carefully check the noise level, model, cooling capacity of the device to ensure that health safety for users. Should choose to buy new, genuine fans at reputable electronics stores and supermarkets to ensure quality and have the best warranty policy. In addition, choose the right air conditioner fan that is suitable for the living room area because the bigger the fan capacity, the more power it will use when used and the noise will be louder.

GS Xiulin Ruan next to new paint The paint is capable of reflecting 98% of sunlight as well as ultraviolet (UV) rays through the atmosphere into the space. During the test, this paint makes the surface temperature 4.50C lower than ambient temperature, even in strong sunlight. It is expected that this paint can be available on the market in 1-2 years. Reflective white paints are now much better than dark roofing materials, but only reflect 80% -90% of sunlight and absorb UV. This means they cannot cool surfaces below ambient temperature. New coatings do this, resulting in fewer need for air conditioners and reduced air conditioning emissions. “Our paint can help fight global warming by helping to cool the earth, which is the coolest point,” said Professor Xiulin Ruan of the research group at Purdue University. According to Professor Xiulin Ruan, painting a roof with an area of ​​93 square meters will save 10kW of electricity consumption of the air conditioner. The substance playing an important role in this new paint is barium sulphate. Unlike conventional titanium dioxide pigments, it does not absorb UV rays. This super white paint uses standard acrylic solvents and can be manufactured like conventional paints, the researchers said. The new paint will cost the same as today’s paints, they added, because barium sulfate is actually cheaper than titanium dioxide. However, it is necessary to evaluate the durability of this paint for a longer time.
