How does an air conditioner cool and how does it heat?

To put it simply, Freon changes from a low-pressure liquid state to a gaseous state in the indoor unit, and because the liquid state becomes a gaseous state to absorb heat, the indoor greenhouse will fall, which is why we are refrigerating, on the contrary, Freon will be exothermic from a gaseous state to a liquid state, so the temperature will be raised.

Air conditioning refrigeration The low-temperature liquid refrigerant evaporates into a gaseous state on the heat exchanger of the indoor unit and absorbs heat, cools the surrounding air, and the gaseous refrigerant is compressed into a high-temperature and high-pressure gas by the compressor and cooled by the outdoor condenser to release heat into a liquid, and then the liquid refrigerant flows into the indoor unit after throttling and evaporates, so as to achieve the purpose of refrigeration. Air conditioning heating The heating process of air conditioning and the refrigeration process are just opposite, the high temperature and high pressure refrigerant is cooled in the indoor unit to release heat, heat the air around the indoor unit, and the cooled refrigerant is evaporated and absorbed in the heat exchanger of the outdoor unit after throttling, and then compressed into a high temperature and high pressure gas by the compressor to flow into the indoor unit, so that the cycle achieves the purpose of heating.

Air conditioners use the principle of heat exchange (evaporation takes away heat) When cooling, refrigerants are used to evaporate and absorb indoor heat in the indoor evaporator. Then use the compressor ** to evaporate the gas, (by the throttle valve to separate the high pressure and low pressure) compressed into a liquid and then dissipated in the condenser of the outdoor unit, is the liquid after heat dissipation through the throttle valve by the high-pressure liquid, immediately evaporated into gas, continue to take away the heat. Heating is the use of a four-way valve to change the direction of circulation (that is, the reverse flow of refrigerant) for heating.

The compressor circulates to absorb hot air and release cold air. Heating means that there is an electric furnace wire blown out by a fan.

This is the cooling and heating principle of air conditioners! The dotted line is heating, and the solid line is refrigerating!

How does an air conditioner cool and heat? When the compressor converts the gaseous freon into liquid freon at high temperature and high pressure, it is sent to the indoor unit, so as to collect a large amount of heat.

How does an air conditioner heat up, and what is its heating principle?

First of all, let's understand what air conditioning is. An air conditioner is a unit that is used to provide a space area with the ability to handle changes in air temperature. Its function is through the process of liquefaction and gasification of freon, the heat is absorbed at the evaporator and transferred to the condenser for release, so as to realize the transfer of heat and achieve the purpose of heating and refrigeration to meet the requirements of human comfort or process.

The principle of air conditioning heating: When the air conditioner is heating, the fluorine oxygen is pressurized by the compressor to become a high-temperature and high-pressure gas, which enters the condenser of the indoor unit, and the condensation is liquefied and exothermic to become a liquid, and the indoor air is heated at the same time, so as to achieve the purpose of increasing the indoor temperature. The liquid freon is depressurized by the throttling device, enters the heat exchanger of the outdoor unit (at this time, the evaporator), evaporates and vaporizes and absorbs heat to become a gas, and at the same time absorbs the heat of the outdoor air, and the fluoro-oxygen that becomes a gas enters the compressor again to start the next cycle.

So. The air conditioner heating started working. Your winters aren't cold anymore either.

So, how many degrees is the right air conditioner to set in winter? 20°C is the optimal temperature setting point for the human body。Originally, there were more clothes to wear in winter, and the problem of setting too high would cause the human body to sweat, and the large difference between indoor and outdoor temperatures would easily lead to colds, and the right temperature could also save energy.

Extension material. Disadvantages of air conditioning and heating

It can't be heated quickly. If there is frost, it must be defrosted first, and this process has to wait about 10 to 20 minutes. If the outdoor temperature is lower than -5°, the air conditioner will not work, and the heating effect will not be good.

The current standard working temperature of the air conditioner is 7°, so it is better to choose the inverter air conditioner when you choose, and the minimum temperature can be -15°.

There are a few reasons why the air conditioner doesn't heat up:

There is a large temperature difference between indoor and outdoor. When the outdoor temperature is very low, remember to close the doors and windows of the room, and wait for ten or twenty minutes.

After a long spring, summer and autumn, a lot of dust will accumulate inside the air conditioner, so clean it first after winter to help the air conditioner run normally. Many people think that it is not necessary, but in fact it is completely wrong.

Check for freon. It is not only the need for fluorooxygen for refrigeration, but also the lack of freon will also affect the heating of air conditioners. Before winter, you can check whether there is a lack of freon and replenish it in time.

Voltage. Voltage issues are also very common. Winter and summer are the peak of electricity consumption, and unstable voltage is also one of the factors that cause the abnormal operation of air conditioners. When troubleshooting the heating problem of the air conditioner, you can consider whether the voltage meets the standard.

Connect the power supply of the air conditioner and click the Switch button on the remote control to turn on the air conditioner. Click the Mode button on the remote control to adjust the air conditioning mode and switch between refrigeration, heating, dehumidification, and automatic. Adjust to the heating mode, and you will see a small arrow pointing to "Heating" on the remote control display.

The air conditioner will also display an icon corresponding to the heating.

Adjust the " button on the panel to adjust the temperature.

Adjust the temperature, the maximum can be adjusted to 30, generally to 25 is appropriate, too high for the long-term operation of the air conditioner, damage to the air conditioner;

Turn down the temperature, it is low outside in winter, it must not be lower than the room temperature, otherwise the air conditioner will not work.

Note: The panel will continue to display the room temperature for a few seconds after the temperature is set.

Adjust the "Wind Speed" button to adjust the speed at which the air conditioner blows.

Description: The wind speed is divided into low, medium, high and super strong, the faster the wind speed, the faster the heating effect; Sometimes, we find that the heating effect is not very obvious, so we have to consider whether to adjust the wind speed to the minimum.

Adjust the "Environment" button and select the environment mode: Dining Room, Meeting Office, Bedroom, Normal.

Adjustments" function"button to select functions such as timing, auxiliary heat, and blowing direction.

Adjust the air outlet:

Although the wind of the air conditioner is hot in winter, it cannot be blown directly on the person's body to prevent cold. Therefore, if you find that the air conditioner blows to people, especially babies, you should adjust the air outlet.

Note: The air outlet can be automatically swept or fixed, and the most convenient is to control it with a remote control.

It takes a certain amount of time for the air conditioner to heat up, and when the room temperature rises, the temperature of the air conditioner panel also changes. When the air conditioner is heating, the plug-in will freeze and frost, so the air conditioner will stop blowing during the partition time, enter the automatic defrost state, and the panel light will keep flashing, don't think it's broken! Don't even turn it off!

Question: The bull's head is not the horse's mouth.

What I asked was how KEPCO air conditioners make heat.

It's not any other air conditioner.

It's cold wind when the question comes out.

The method of adjusting the cold air of the air conditioner to the hot air is as follows:

1. Click the "Mode" button on the remote control to adjust the air conditioning mode to the heating mode. At the same time, the display screen of the remote limb closure control will see the prompt graphic of the heating mode, and the corresponding heating icon will also be displayed on the air conditioner.

2. Adjust to the required temperature, and then wait patiently for the air conditioner to run. In heating mode, the initial preparation time is longer, so don't worry about how hot air hasn't come out yet.

3. If the air conditioner still does not produce hot air or the wind is small after a period of time, you can use the remote control board to adjust the wind speed and the swing of the fan blades.

The air-conditioning mode generally has refrigeration, heating, automatic, dehumidification, air supply and other modes, and the air-conditioning mode is set to the heating mode by pressing several times.

After the air conditioner is turned on, select the mode button or function key button, and Guansheng has insight into the pattern change on the remote control screen, when the pattern is displayed as the sun, it is the function of heating, that is, the function of heat control.

When the air conditioner is heating, the compressor will pressurize the gas freon to make it a high-temperature and high-pressure gas, and then condense and liquefy it through the heat exchanger of the indoor unit, release a large amount of heat, and increase the temperature of the indoor air.

The air conditioner has two kinds of filial piety functions: cooling and heating, which can be adjusted according to the needs of the indoor temperature. The following are the steps for an air conditioner to modulate heat from refrigeration:

Air conditioner on: Turn the air conditioner on and select the heating mode.

Switch back air vents: Switch the air outlet of the air conditioner to the room so that air can enter the air conditioner.

Indoor unit reversing: Different brands and types of air conditioners, the reversing mode of the indoor unit is also different, and it is necessary to operate according to the specific operation manual, and the indoor unit is reversed to the heating mode.

Compressor start: During refrigeration, the compressor of the air conditioner is turned off, and the compressor needs to be started to make it start working when heating.

Heater heating: The heating mode of the air conditioner needs to heat the indoor air through the heater to increase its temperature and achieve the purpose of heating up.

Temperature setting: Adjust the temperature setting value of the air conditioner according to actual needs.

Timer switch: If you need to heat up within a certain time, you can set a timer switch to achieve automatic power on/off.

Precautions: Cooling and heating need to be cleaned and maintained regularly to ensure their normal operation.

When heating, the doors and windows should be kept closed as much as possible to avoid heat loss and affect the indoor temperature.

When using a heater for heating, you should pay attention to safety, clean up and remove dust in time to prevent fire.

1. Align the remote control with the air conditioner, 2. Press the mode to switch to heating mode.

Air conditioning heating isIt refers to the process of using the heating function of an air conditioner to increase the indoor temperature。In most cases, air conditioning heating will increase the temperature in the room, but sometimes it will also decrease the indoor temperature.

The following are the basic principles of air conditioning heating and how to achieve heating::

Air conditioning heating is mainly achieved through components such as compressors, heat exchangers, and condensers in outdoor units. When the outside temperature is low, the compressor in the outdoor unit of the air conditioner will start to run, causing the refrigerant to circulate and bring heat from the outside into the room. When the outdoor temperature gradually rises, the heating effect of the air conditioner will gradually improve.

There are several ways to achieve air conditioning heating, including:

Turn on the heating function of the air conditioner.

Use the remote control or the heating button on the control panel.

Use the room controller on the indoor unit to manually set the heating mode.

Open the air inlet or outlet of the indoor unit to improve the heating efficiency.

Manually setting the heating mode is the most convenient method. After turning on the heating function of the air conditioner, you can select the desired mode through the remote control or the heating button on the control panel, and then wait for the air conditioner to heat up. In addition, the heating mode can also be easily set manually by using the indoor controller on the indoor unit.

Suppose you want to enjoy a warm room in winter, you can turn on the heating function of the air conditioner by following these steps:

Turn on the heating function of the air conditioner and select the desired mode (usually auxiliary heating) - Generally, the default is the refrigeration cavity source mode, so you need to manually select the auxiliary heating.

Open the air inlet or outlet of the indoor unit - improve heating efficiency.

Wait for the air conditioner to heat up - it will take about 20-30 minutes, depending on the room size and the type of air conditioner.

Turn off the power to the air conditioner - to be safe.

In this way, you can enjoy a warm room in the winter.

The principle of air conditioning heating:

When the air conditioner is heating, the gas freon is pressurized by the compressor to become a high-temperature and high-pressure gas, which enters the heat exchanger of the indoor unit (condenser at this time), condenses and liquefies heat to become a liquid, and at the same time heats the indoor air, so as to achieve the purpose of increasing the indoor temperature.

The liquid freon is depressurized by the throttling device, enters the heat exchanger of the outdoor unit (in this case, the evaporator), evaporates and vaporizes to absorb heat and become a gas, and at the same time absorbs the heat of the outdoor air (the outdoor air becomes colder). Freon, which becomes a gas, enters the compressor again to start the next cycle.

The heating principle of air conditioning is mainly a method of using the basic working principle of the refrigeration cycle, which discharges the heat in the room to the outside by running in the reverse direction in the refrigeration cycle, and at the same time conveys a high-temperature and dry airflow to the room to increase the room temperature. The following is a detailed introduction to the principle and operation process of air conditioning heating.

Air conditioners employ a mechanism called a heat pump through which half of the heat in the room comes from the high-temperature process of the outdoor air. The higher the air temperature, the more additional heat is provided for indoor heating, so heating can vary depending on the time of day and temperature. The details are as follows:

1.The refrigerant flowing in the evaporator absorbs heat from the air to form low-temperature, low-pressure vapors.

2.Next, the compressor compresses these low-temperature and low-pressure vapors into high-temperature and high-pressure vapors.

3.At the same time, these high-temperature and high-pressure vapors pass through the pipes in the condenser and enter the pipes through the water pump, cooling and releasing the heat, reducing the indoor temperature.

4.The heat from the high-temperature and high-pressure steam then sends hot air to the room through ducts and fans in the evaporator, which in turn raises the room temperature.

In some harsh cold environments, heat pumps or other heat sources (such as electrically assisted heat sources) need to be added to support the indoor heating effect. Due to the influence of heavy haze areas, the use of air as the only heating source is unstable. Therefore, in some areas, people are more inclined to choose underfloor heating as a home heater, and only use air conditioning in summer to cool down.

Air conditioning heating is based on the refrigeration cycle mechanism, through reverse transportation, the heat in the room is discharged to the outside, and then the hot and dry air flow is delivered to the room to increase the room temperature. The higher the temperature, the higher the heating output, so the heating varies depending on the time of day and temperature. It is important to note that in order to make the air conditioner work effectively for a long time and the cooling and heating effect is better, people should also regularly clean the air conditioner and replace the filter element, and regularly evaluate the wear and tear of the cooling and heating units and machines for maintenance and replacement.
