What mode of air conditioner is refrigeration? What is the principle of air conditioning refrigerati

I believe that people should be more familiar with the household product of air conditioning, air conditioning is very common in home use, I believe that many people want to know what mode of air conditioning is refrigeration, because air conditioning in use of cooling and heating is very critical. At the same time, it is also necessary for people to understand what the principle of air conditioning and refrigeration is, because in the process of using air conditioning, only by understanding this principle can it be used better.

What mode of air conditioner is refrigeration?

1. The remote control of the air conditioner adjusts the refrigeration form, press the key point of the air conditioner against the remote control to turn on the air conditioner, and then press the form key of the air conditioner remote control. There are five forms of active, refrigeration, dehumidification, heating and air supply, press the form button to switch a form, when the remote control shows refrigeration, the air conditioner is the refrigeration form.

2. Prepare a smart phone with infrared function in the form of mobile phone refrigeration, ** an all-round remote control app, open the all-round remote control app, enter the home page of the app, and click on the Midea air conditioner.

3. Enter the remote control interface of the air conditioner, the mobile phone is facing the air conditioner, click on the key point to turn on the air conditioner, what appears at the moment is the active form, you can click the form key to switch the form, the form is active, refrigeration, heating, ventilation and dehumidification. Click the form button to switch a form, when the screen shows that the refrigeration is, the air conditioner is the refrigeration form.

What is the principle of air conditioning refrigeration?

1. Air conditioning is divided into single cold air harmonic and cold and warm air conditioning, the operating principle is the same, and most of the refrigerants used to be used in air conditioning are freon. The characteristic of Freon is that when it changes from gaseous to liquid state, it releases a lot of heat.

When the liquid state is changed to the gaseous state, it absorbs a lot of heat. (i.e., first heat absorption, gasification, and then liquefaction and heat release) air conditioning is planned 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 and becomes a liquid refrigerant at room temperature and high pressure, so the outdoor unit blows hot air.

3. Then go to the capillary tube and enter the transpirator (indoor unit), because the space of the refrigerant suddenly increases after the capillary arrives at the transpirator, the pressure decreases, and the liquid refrigerant will vaporize and become a gaseous low-temperature refrigerant, and then absorb a lot of heat, and the transpirator will become cold.

Fourth, the fan of the indoor unit blows the indoor air through the transpirator, so what the indoor unit blows out is a cool breeze. When the water vapor in the air meets the cold transpirator, it will condense into water droplets and flow out down the water pipe, which is why the air conditioner will produce water.

The above explanation is what mode of air conditioning is refrigeration, in fact, the general air conditioner has a remote control, and the remote control has two explanations of refrigeration and heating, so as long as you follow the instructions on the remote control to solve the use, it also explains what the principle of air conditioning refrigeration is, in fact, the refrigeration principle of each air conditioner is roughly the same, so after reading the above answer, you should have a detailed understanding.

What is the 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. 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, causing the high-pressure refrigerant vapor to condense 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 to absorb the surrounding heat. At the same time, the cross-flow fan continuously enters the ribs of the evaporator for heat exchange, and sends the cooled air to the room after heat release. In this way, the indoor air is constantly circulating and flowing to achieve the purpose of reducing the temperature.

Air conditioner is an air conditioner that regulates temperature and humidity, and a hanging air conditioner is a unit used to provide a space area (generally closed) to deal with changes in air temperature. Its function is to adjust the parameters such as temperature, humidity, cleanliness and air flow rate of the air in the room (or enclosed space or area) to meet the requirements of human comfort or process.

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.

Air conditioners are accompanied by dehumidification during the refrigeration process. The relative humidity of the environment where people feel comfortable should be around 40-60%, and when the relative humidity is too high above 90%, even if the temperature is within the comfortable range, the person still feels bad.

When you press and hold the refrigeration button on the remote control of the Gree air conditioner, and the word "cool" appears on the display, it usually means that the air conditioner has entered the auxiliary cooling mode.

This is a special function in Gree air conditioner, which is suitable for scenarios that quickly reduce the indoor temperature in refrigeration mode. In auxiliary cooling mode, the air conditioner will operate at a higher air velocity and a lower temperature setting to quickly reduce the ambient temperature.

This can be used when you are first entering the room, or when you need to quickly lower the indoor temperature to provide faster cooling. Normally, the auxiliary cooling mode does not last long, but is used to cool down quickly before switching to the normal cooling mode.

It is important to note that the auxiliary cooling mode consumes more energy, so it is necessary to choose according to your needs when using it. If you just need to maintain a comfortable indoor temperature, you can choose the normal cooling mode to be more energy-efficient.

If you have more questions about the specific use method or other functions of the air conditioner, it is recommended to refer to the instruction manual of the Gree air conditioner or contact the Gree after-sales service center for more accurate answers and guidance.

Precautions for using air conditioners in summer

1. Set the temperature reasonably: In the hot summer, the air conditioner can provide a comfortable indoor environment. However, too low a temperature setting may cause physical discomfort or health problems. It is recommended to set the temperature of the air conditioner within a suitable range, generally between 25-28 degrees Celsius.

2. Set a reasonable use time: try to avoid continuous use of air conditioners for a long time. Use the air conditioner intermittently and turn off the air conditioner at regular intervals to allow the air to circulate in the room to reduce the burden on the body.

3. Use energy-saving mode: Modern air conditioners are usually equipped with energy-saving mode. When using air conditioners in the summer, you can choose the energy-saving mode to reduce energy consumption, as well as reduce the environmental impact.

4. Clean the filter regularly: Due to the large amount of dust and pollutants in the air in summer, the filter of the air conditioner is easy to be blocked. Cleaning the filter regularly can maintain air circulation and purification effect, while improving the efficiency of the air conditioner.

Sleep on automatically is good.

The automatic mode of the air conditioner is that the air conditioner can automatically adjust the refrigeration temperature, refrigeration efficiency, blowing size and other parameters of the air conditioner according to the current indoor ambient temperature, humidity and other states, which is more intelligent and humanized than the fixed setting.

For example, if the temperature at night is lower than during the day, the air conditioner will detect the low temperature after turning on the automatic mode and turn up the air conditioner temperature, so that the user can use it more comfortably and not too cold.

The refrigeration mode of the air conditioner is relative to the working mode of heating, dehumidification and other functions, and the air conditioner will reduce the indoor temperature according to the set temperature value after turning on the refrigeration mode.

There is no conflict between the refrigeration mode and the automatic mode, in other words, we can use the automatic mode based on the refrigeration mode to make the air conditioner more intelligently cooled. Cooling with automatic mode has advantages over simple cooling in terms of user experience and power consumption.

There is no difference between the power consumption of the cooling mode and the automatic mode, and there is no problem of saving power in that mode.

The automatic mode automatically selects "cooling" or "heating" according to the outside temperature, and it can also automatically control the speed of the internal fan according to the indoor temperature to achieve the purpose of indoor constant temperature as much as possible. Refrigeration is a single refrigeration mode. Doesn't beat on its own and something else, the two power consumption repentances are the same.

The smoky symbol for the refrigeration mode is usually a snowflake pattern, or it can be a blue "cool" lettering.

The refrigeration mode also has different temperature settings, which can be adjusted as needed. When using the cooling mode, it is recommended to set the indoor temperature within a comfortable range to avoid wasting energy, and to ensure that the difference between the indoor temperature and the outside temperature is not too large to avoid affecting your health.

An air conditioner is an air conditioner. It refers to the equipment that uses artificial means to regulate and control the temperature, humidity, flow rate and other parameters of the ambient air in the building or structure.

Generally, it includes cold source heat source equipment, cold and hot medium transmission and distribution system, terminal ant material device and other major parts and other auxiliary equipment. It mainly includes refrigeration hosts, pumps, fans and piping systems. The terminal device is responsible for using the cold and heat from the transmission and distribution to specifically treat the air state and make the air parameters of the target environment meet certain requirements.

Air conditioning is an indispensable part of modern life, air combustion calendar provides people with coolness, but at the same time, air conditioning is always on is also easy to cause diseases, such as "air conditioning disease", etc., need to be used with caution. <>

The refrigeration mode is one of the most basic modes in an air conditioner. Refrigeration mode refers to the mode in which the air conditioning unit will absorb heat and cool the room air below the set temperature when the room temperature is higher than the set temperature. In this mode, the air conditioning unit will take the method of drainage and condensation to achieve the effect of refrigeration.

In addition to the refrigeration mode, there are many other modes of air conditioning, such as heating mode, air supply mode, dehumidification mode and so on. Although these modes are different from the refrigeration mode, they also have their own roles and effects, and can be selected according to actual needs.

When people feel the heat in the summer weather, the air-conditioned cooling mode becomes their lifesaver. With the refrigeration mode, the air conditioner can quickly reduce the indoor temperature and bring a cool feeling to people. In addition, in the hot summer, if the cooling mode of the air conditioner is not used in time, the indoor temperature will continue to rise, and people will feel uncomfortable because of the high temperature, resulting in both physical and mental consumption.

In general, the cooling mode of the air conditioner is a very practical function, especially in the summer when the weather is very hot, by using this mode, we can drop the room temperature above the set temperature of the air conditioner to a suitable range, bringing us a refreshing feeling and improving our work and quality of life. <>

The principle of refrigeration is divided into two parts:

1.The binary solution is heated and boiled by a heat source in the generator, and the resulting refrigerant vapor is condensed into a refrigerant liquid in the condenser. The liquid refrigerant enters the evaporator after being throttled through the U-shaped tube, and is ejected by the evaporator at a low disturbance pressure.

The liquid refrigerant evaporates and absorbs the heat of the refrigerant, creating a refrigeration effect.

2.The concentrate flowing out of the generator is cooled and depressurized by the heat exchanger and then flows into the absorber, where it mixes with the original solution of the absorber to form a medium concentration concentrate. The medium-concentrated solution is delivered and sprayed by an absorption pump, and the refrigerant vapor from the evaporator is absorbed into a dilute solution.

The dilute solution is pumped to the generator, and the refrigerant vapor generated by the heat source forms a concentrated solution again and enters the next cycle.

To sum up, any refrigeration equipment is composed of four parts (compressor, condenser, evaporator, throttling device), and the refrigerant absorbs or releases heat through the change of physical state in the refrigerator to achieve the effect of cooling or heating.

Its function is to regulate the temperature, humidity, cleanliness and wind speed of the indoor (or enclosed space or area) air to meet the requirements of human comfort or process flow.

In the design and manufacture of air conditioners, it is generally allowed to control the temperature between 16 -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 temperature changes when entering and exiting the room, and they are prone to colds.

In the refrigeration process of the air conditioner, it is accompanied by dehumidification. The relative humidity in a comfortable environment should be around 40-60%. When the relative humidity is too high, such as more than 90%, even if the temperature is within the comfort range, the person still does not feel good.

1. The compressor compresses the gaseous freon into a gaseous freon at high temperature and high pressure, and then sends it to the condenser (outdoor unit) to dissipate heat and becomes liquid freon at room temperature and high pressure, so the outdoor unit blows hot air. Refers to the liquid freon through the capillary, into the evaporator (indoor unit), the space suddenly increases, the pressure decreases, the liquid freon will vaporize, into gaseous low temperature freon, thereby absorbing a large amount of heat, the evaporator will become cold, the indoor unit fan will blow the indoor air from the evaporator, so the indoor unit blows out of the cold air; When the water vapor in the air meets the cold evaporator, it will condense into water droplets and flow out down the water pipe, which is why the air conditioner will produce water. Then the gaseous freon returns to the compressor to continue compressing and continuing the cycle.

2. There is a component called the four-way valve during heating, so that the flow direction of Freon in the condenser and the evaporator is opposite to that of refrigeration, so when heating, the outdoor air blows cold air, and the indoor unit blows hot air. In fact, it is the principle of expulsion of heat during liquefaction (from gas to liquid) and absorption of heat during vaporization (from liquid to gas) learned in Lao Jian's junior high school physics.

3. Lithium bromide air conditioning refrigeration principle, the lithium bromide air conditioning refrigeration principle to be specially proposed here is different from compression air conditioning, the working fluid used in absorption refrigeration is usually a binary solution, composed of two substances with different boiling points. Among them, the substances with low boiling point are refrigerants, and the substances with high boiling points are absorbents. Therefore, binary solutions are also known as refrigerant-absorbent working fluid pairs.

A binary solution is a mixture of two substances that do not chemically interact with each other. The various physical properties of this homogeneous mixture (e.g., pressure, temperature, concentration, etc.) are completely consistent throughout the mixture, and they cannot be separated into the original constituent substances by purely mechanical precipitation or centrifugation.
