With the continuous development of the society, people's living standards are constantly improving, and the quality of life is getting better and better. Almost every family has air conditioner installed, whether it is in summer or winter, everyone wants to use it. Electrical appliances have brought great convenience to our lives. Many consumers do not know the principle of air conditioning and refrigeration. So, what is the principle of air conditioning refrigeration ? What are the buying skills of air conditioning?
First, what is the principle of air conditioning refrigeration?
1. The binary solution is heated and boiled by the heat source in the generator, and the refrigerant vapor is condensed into a refrigerant liquid in the condenser. The liquid refrigerant enters the evaporator after being throttled by the U-shaped tube, and is sprayed under the low pressure condition by the evaporator, and the liquid refrigerant evaporates to absorb the heat of the refrigerant to generate a cooling effect.
2. The concentrated solution flowing out of the generator is cooled by the heat exchanger, depressurized, and then flows into the absorber, and is mixed with the original solution of the absorber to become a concentrated solution of intermediate concentration. The intermediate concentration solution is pumped and sprayed by the absorber pump to absorb the refrigerant vapor coming out of the evaporator into a dilute solution. The dilute solution is pumped by the generator to the generator, and the refrigerant vapor is again generated by the heat source to form a concentrated solution again, and the next cycle is entered.
3, the principle of lithium air conditioning refrigeration, and compressed air conditioning, the working medium used in absorption refrigeration is usually a binary solution, composed of two substances with different boiling points. Among them, the low boiling point substance is a refrigerant, and the high boiling point substance is an absorbent. Therefore, the binary solution is also referred to as a refrigerant-absorbent working fluid pair.
4. A binary solution refers to a mixture of two substances that do not interact with each other. The various physical properties of such a homogeneous mixture (such as pressure, temperature, concentration, etc.) are completely uniform throughout the mixture and cannot be separated into the original constituents by pure mechanical precipitation or centrifugation.
Second, the air conditioning purchase skills
1. When purchasing air conditioners, brand and word of mouth are the first to look at. The size of the brand directly determines the quality and performance of the air conditioner. Therefore, when you buy a home air conditioner, don’t look at how beautiful the appearance is. The key is to look at it. Whether the brand is domestic first-line or second-line. Foreign brands can also be considered if funding permits. Of course, you can't just look at the brand. How about the brand's reputation?
2, then look at the type of air conditioning, there are ordinary air conditioning, as well as central air conditioning. Both types of air conditioners have their advantages and disadvantages. Users can choose according to their own needs. If it is a villa, then the choice of central air conditioning is the best, the entire floor can enjoy the cool cold wind. The ordinary household air conditioner is most suitable for the mass family, economical, easy to install, and convenient for later maintenance. However, ordinary household air conditioners are divided into wall-mounted and three-dimensional, and the interior of the room can be wall-mounted. The living room can be stereoscopic. of.
3, the last is the need to look at the number of air conditioning, the average number of household air conditioning is determined according to the room area, if it is 20 square meters of room, then the choice of one is enough, you can quickly reduce 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.
The above is Xiaobian for everyone to introduce the principle of air conditioning refrigeration and air conditioning purchase skills, if you want to know the air conditioning refrigeration friends can refer to Xiaobian for everyone to introduce, I hope to help everyone, if you still want For more information on decoration, please continue to pay attention to the decoration home network.
