How does an air conditioner work and how does an air conditioner work?

Nowadays, many people have air conditioners in their homes, which can be said to be one of the common appliances in summer. Although many people use air conditioners in their homes, most people don't know how air conditioners work. Do you know the principle of air conditioning?

Generally, air conditioners are divided into two types: cooling and heating. Today we will take a look at the working principle of air conditioning and see what principle the air conditioner we usually use works on. Friends who want to know how the air conditioner works can take a look.

How it works:1. Air conditioners are divided into single-cooling air conditioners and dual-purpose air conditioners, and the working principle is the same.

The most commonly used refrigerant in air conditioners is freon. Freon is characterized by releasing a large amount of heat when it turns from a gas to a liquid. When it changes from a liquid to a gas, it absorbs a lot of heat.

Air conditioners are designed according to this principle. 2.The compressor compresses the gaseous refrigerant into a gaseous refrigerant with high temperature and high pressure, and then sends it to the condenser (outdoor unit) to dissipate heat to become a liquid refrigerant at room temperature and high pressure, so the outdoor unit blows hot air.

Then it goes to the capillary and goes to the evaporator (indoor unit). Due to the sudden increase in space and the decrease in pressure after the refrigerant reaches the evaporator from the capillary, the liquid refrigerant will vaporize and become a gaseous cryogenic refrigerant, which will absorb a large amount of heat and the evaporator will become cold. The fan of the indoor unit blows out the indoor air from the evaporator, so the indoor unit blows out cold air.

When the water vapor in the air encounters an icy evaporator, it condenses into water droplets that flow out along the water pipes, which is why air conditioners produce water. 3.When heating, there is a component called a four-way valve that causes the refrigerant to flow in the condenser and evaporator in the opposite direction to the refrigeration.

So when heating, cold air blows outdoors and hot air blows indoors. In fact, it is the principle of liquefaction (from gas to liquid) that releases heat and absorbs heat during vaporization (from liquid to gas). 4.

The working principle of environmental protection air conditioning: the water in the water tank is continuously pumped out by the circulating water pump and evenly sprayed on the evaporation filter layer through the water distribution system. The hot air from the outside enters the evaporative cooling medium and is fully exchanged with the water in the evaporative cooling medium Celdek (a honeycomb filter layer made of a special material to make the cooling effect more ideal, a patented product of Swedish high-tech).

Cool, clean air cooled by water evaporation and heat absorption is forced into the room through a low-noise fan to create hot air in the room. The above is an introduction to the working principle of air conditioning. The working principle of air conditioning is simple.

Generally, air conditioners use external compressors and built-in compressors to produce cooling effects. Generally, air conditioners have freon. Freon is a refrigerant that is compressed and cooled by the outside unit of an air conditioner.

When we choose an air conditioner, we can choose some inverter air conditioners. The working principle of the inverter air conditioner is similar, but the inverter air conditioner has an additional inverter compressor, which saves electricity and saves energy, and is a better air conditioner.

In modern urban environments, both central cooling and individual air conditioning are designed to provide cooling and a comfortable temperature. While both serve this purpose, they operate in very different ways and cost. In this article, we'll dive into the pros and cons of central cooling and individual air conditioning, and how they affect our lives.

First of all, we need to understand how central cooling and individual air conditioning work. Central cooling refers to the use of a refrigerant water circulation system to cool air in a building or area through a large refrigeration station. Whereas, independent air conditioning is usually installed in each room or in a bent building, such as split air conditioning or ** air conditioning.

When it comes to energy efficiency and cost, district cooling has clear advantages. Since it is operated in a large area or building, energy can be used more efficiently. In contrast, each individual air conditioning unit is aware of a certain amount of wasted energy because they operate separately and have no synergistic effect.

In addition, the cost of central cooling equipment is usually lower than installing individual air conditioning in each room or building.

However, individual air conditioning may be more appropriate in some cases. For example, when a specific room or area needs to be cooled or heated quickly, individual air conditioners can reach the target temperature more quickly. In addition, the installation of individual air conditioners is more flexible and can be carried out wherever it is needed, regardless of the influence of other rooms or buildings.

Overall, central cooling and individual air conditioning have their own advantages and limitations. When deciding which system to use, we need to consider specific needs and environments. For example, for large, continuously needed cooling buildings or areas, such as office buildings or shopping malls, district cooling may be a better option because it allows for more efficient use of energy and lower overall operating costs.

However, for venues that require rapid cooling or heating, such as laboratories or restaurants, individual air conditioning may be more suitable.

In future construction, we are likely to see more large cities and regions adopting district cooling to achieve greater energy efficiency and lower environmental impact. However, for specific places and specific needs, individual air conditioning still has its important place. The final choice depends on the specific needs and environment of the burial tank, as well as the comparison of the features and benefits that the two systems can provide.

What air conditioner operators should pay attention to.

Pay attention to whether the work is normal, such as high and low pressure. The oil level, compressor suction, exhaust temperature, if there is a leak, should be found and maintained in time, whether the filter screen and condenser are dirty should be cleaned in time, and whether there is abnormal noise when the machine is working.

How does an air conditioner work?

How does an air conditioner work? --It is the use of material evaporation and evaporation to absorb heat and achieve cooling. The current material is high-pressure liquid refrigerant Freon R22) (such as the temperature of evaporation and absorption air in the evaporator after throttling is low-temperature dry balance and low-pressure steam refrigerant; The low temperature and low pressure steam refrigerant flows into the compressor and compresses, becoming the pressure of the high temperature and high refrigerant vapor.

After cooling and depressurizing by the condenser, it comes out as a high-pressure liquid refrigerant, and after throttling, it is evaporated through the evaporator and recycled. There is a fan above the evaporator that circulates air through the evaporator; Allow the air to cool. For example:

The spray is applied to your **, and when it evaporates, it absorbs your **temperature, so you feel cool. After the empty regulator is energized, the low-pressure steam of the refrigerant in the refrigeration system is sucked into the Gaoxiao compressor and compressed into high-pressure steam, which then enters the condenser. At the same time, the outdoor air drawn in by the axial fan flows through the condenser, taking away the heat released by the refrigerant and condensing the high-pressure refrigerant vapor into a high-pressure liquid.

The high-pressure liquid is sprayed into the evaporator after passing through the filter and throttling mechanism, and evaporates at the corresponding low pressure, absorbing the surrounding heat. At the same time, the cross-flow fan continuously feeds the air into the evaporator fins for heat exchange, and sends the exothermic cold air to the room. In this way, the indoor air is constantly circulating to lower the temperature.

What are the main tasks of an air conditioner?

Generally, it is the installation, commissioning and maintenance of air conditioners. Some large air conditioners also need to be checked regularly. Make sure your air conditioner is working properly.

1. Principle of air conditioning and refrigeration: After the air conditioner is energized, the low-pressure steam of the refrigerant in the refrigeration system is sucked in by the compressor and compressed into high-pressure steam and discharged to the condenser, and the indoor air is continuously circulated to achieve the purpose of reducing the temperature.

2. The principle of air conditioning heating: the shape rock is to reverse the position of the suction and exhaust pipes of the refrigeration system through electromagnetic commutation. The indoor coil of the original refrigeration evaporator becomes a condenser during heating, so that the refrigeration system absorbs heat from the outside and releases heat from the interior to achieve the purpose of heating.

3. The working principle of air conditioning: air conditioning is divided into single cooling air conditioning and cold and heating dual-purpose air conditioning, the working principle is the same, and most of the refrigerants used in air conditioning before were freon. The properties of Freon are:

When the gas stockings change from a nuclear state to a liquid state, a large amount of heat is released. When the liquid state changes from a gaseous state, it absorbs a large amount of heat. (i.e., first absorbing heat and gasification and then liquefiing and heat release) air conditioners are designed according to this principle.

The main uses of air conditioners are:

1. Cooling: In the design and manufacture of air conditioners, it is generally allowed to control the temperature between 16 and 32. If the temperature is set too low, on the one hand, it will increase unnecessary power consumption, and on the other hand, when the temperature difference between indoor and outdoor is too large, people can not quickly adapt to the temperature change in and out of the room, and they are prone to colds.

2. Dehumidification: The air conditioner is accompanied by dehumidification during the refrigeration process. The relative humidity of the environment where people feel comfortable should be around 40% to 60%, and when the relative humidity is too large and above 90%, even if the temperature is within the comfortable range, the feeling is still not good.

3. Heating: Heat pump and electric air conditioners have heating function. The heating capacity gradually decreases with the decrease of outdoor ambient temperature, and if the temperature is minus 5, it can hardly meet the heating requirements.

4. Purify the air: The air contains a certain amount of harmful gases such as NH3, SO2, etc., as well as various odors such as sweat, body odor and bathroom odor.

5. Increase the concentration of air anions: The concentration of charged particles in the air will affect the comfort of the human body. The installation of negative ion generators on air conditioners can increase the negative ion degree of the air, make the environment more comfortable, and at the same time have certain medical effects on lowering blood pressure and inhibiting asthma.
