I. Product overview
The principle and process of air conditioning and refrigeration
Air conditioning is short for air conditioning. The main content of the air conditioner is refrigeration, which is artificially made to cool. To understand the principle of air-conditioning and refrigeration, we must first understand the principle of evaporative heat absorption. For example, we have all given injections. When the nurse rubs alcohol on our skin, we immediately feel that the place being rubbed is so cool. Why? This is the result of alcohol evaporation, which absorbs the heat from our skin so we will feel cool. If you put water on your skin, it will feel cool, but it is not as effective as alcohol, because alcohol evaporates more easily than water, which means that the faster it evaporates, the better the cooling. The factors that affect the speed of evaporation are temperature. The higher the temperature, the faster the evaporation. For example, clothes washed in summer dry faster than in winter.
There is also pressure. The lower the pressure, the faster it will evaporate. For example, if you boil water in the plains, you will get 100 degrees, while in the Qinghai-Tibet Plateau, you will boil less than 90 degrees. Because the boiling point is different, water does not boil and evaporate in large quantities until it reaches 100 degrees. However, our air conditioner uses fluorine. Fluorine turns on at minus 30 degrees. When it boils, it evaporates a lot. If we pour fluorine into a water tank, it will evaporate a lot at room temperature and absorb the surrounding heat. The water tank and its surroundings will be very cold. We use a fan to blow the water tank, and the cool breeze will be blown out. But this is a hypothesis, which is not practical, because the fluorine we poured in evaporates immediately, and it is impossible for us to continue to fill it with fluorine. Then how can we reuse fluorine? First of all, we have to find a way to restore the fluorine that has become vapor to liquid fluorine. One way is to pressurize. As long as the gas is pressurized, the gas can be turned into liquid, and the higher the pressure, the easier it is to turn into liquid. For example, the liquefied gas tanks used at home are mostly liquid, which is the compressed liquid of liquefied gas. Another method is cooling. As long as the gas is cooled, the gas can be turned into liquid, and the lower the temperature, the easier it is to turn into liquid. For example, when water is boiled in a pot, there are drops of water on the lid. This is the result of condensation of water vapor in the pot on the colder lid. To solve the problem of changing gas to liquid, there is also a closed system to prevent fluorine from leaking. It becomes an air conditioning system.
