Air conditioning is a more common household appliance nowadays, because it can be cooled or heated, so its usage rate is relatively high. Almost every household will install air conditioners, but air conditioners also have many people working on it. The principle is not very well understood, so what are the working principles of air conditioning? What are the purchasing skills of air conditioning? The following is a small series of decoration home network to introduce to you.
First, the working principle of air conditioning
1. The air conditioner is divided into a single-cooled air conditioner and a dual-purpose air conditioner. The working principle is the same. Most of the refrigerants used in air conditioners beforehand are freon. The characteristic of Freon is that a large amount of heat is released when it changes from a gaseous state to a liquid state. When it changes from a liquid to a gaseous state, it absorbs a lot of heat. (ie, first heat absorption gasification and then liquefaction heat release) air conditioning is designed according to this principle.
2. The compressor compresses the gaseous Freon into a high-temperature and high-pressure gaseous Freon, and then sends it to the condenser (outdoor unit) to become a normal-temperature high-pressure liquid freon, so the outdoor unit blows out hot air.
3. When the water vapor in the air encounters a cold evaporator, it will condense into water droplets and flow out along the water pipe. This is the reason why the air conditioner will discharge water. The gaseous Freon then returns to the compressor to continue compression and continues to circulate.
Second, the air conditioning purchase skills
1. If the area inside the home is relatively small, there is no need to install cabinet air conditioners. The desktop air conditioner can fully meet the needs. Therefore, when installing the air conditioner, we should pay attention to the actual area inside the home and calculate a cost-effective purchase method. It is the way to save money.
2. Compared with other types of household central air conditioners, although the introduction of fresh air in the central air conditioning system of the air duct system can effectively improve the indoor air quality, the air distribution system of the air duct system requires a large construction space, and generally requires a higher housing. At the same time, it is relatively noisy and runs at a high cost. Therefore, the central air conditioner of the duct system is generally not recommended for the family.
3. The number of household air conditioners is determined according to the room area. If it is a 20 square meter room, then choosing one is enough to quickly lower the temperature inside the room. However, if it is 30-40 square meters, then you need to choose 2 air conditioners, so that the temperature in the room can be quickly reduced. By analogy, the larger the housing area, the more natural the number of horses needs to choose.
Air conditioning is now favored by people. It is a dual-purpose one that can be cooled or heated. So what are the working principles and purchasing skills of air conditioners? I want to see the introduction of the above small series. Everyone knows about these. Well, if you still want to know more about the decoration, please continue to pay attention to the decoration home Internet cafe.
