Why can't you open the windows when the air conditioner is on?

On hot summer days, many strive to provide a comfortable atmosphere in their homes and offices.One of the most popular ways to beat the heat is by using air conditioning. But it is important to study the rules for operating the device so that it lasts a long time. It’s worth figuring out whether it’s possible to open the windows when the air conditioner is on or whether this will disrupt its operation.

How an air conditioner works - a brief description of the operating principle

Air conditioner is a device designed for cooling, heating, ventilation and dehumidification of indoor air. It works on the principle of a thermodynamic cycle, which allows heat to be transferred from one place to another. The table describes the characteristics and operating principle of its main elements.

When the air conditioner is turned on, it circulates refrigerant, which cyclically changes its state from gaseous to liquid and back. This allows heat to be transferred from indoors to the surrounding environment, cooling and dehumidifying the air inside the home.

If necessary, the unit can also perform a heating function. For this, a reverse operating cycle is used when the device operates in heat pump mode.

In this case, the compressor compresses the refrigerant. It then passes through a capacitor. Here the refrigerant gives off heat to the environment, increasing its temperature. After this, it passes in a hot state through the expansion valve and evaporator, where it absorbs heat from the environment. Cold air begins to warm up.

When the air conditioner is turned on, it also ventilates, circulating fresh air. This is achieved using a fan. It provides air movement, transfers it through filters to remove dust and other contaminants.

The operation of the device is controlled by a thermostat, which regulates the temperature in the room. A person can set the required temperature indicators. When the set temperature is reached, the thermostat temporarily turns off the compressor and fan.

Refrigerants are usually fluorinated hydrocarbons such as CFCs. However, some types of CFCs can be harmful to the environment because they contribute to the destruction of the ozone layer. In this regard, in recent years there has been an active transition to environmentally safer and energy-efficient alternatives.

What happens if you open a window while the air conditioner is on?

If you open a window while the air conditioner is on, this can lead to inefficient operation of the system and increased energy consumption. Causes:

1. Reverse air flow. When the air conditioner is turned on, it operates on the principle of air circulation. If you open the window, a person will create a reverse flow of air coming from outside. This disrupts the normal operation of the device when it is turned on. This can result in warm air mixing with cooled or heated air. Open windows reduce the efficiency of the unit.
2. Loss of cold or heat. If you open the window when the air conditioner is on, a person allows heat from the street to penetrate while this electric machine is operating in cooling mode. The same thing happens when heated. In this case, an open window allows heat to escape from the house. As a result, the turned on air conditioner must work more intensely. It needs to compensate for the loss of heat or cold, which leads to increased energy consumption and higher energy bills.
3. Loss of drying effect. When the air conditioner is turned on, it also performs the function of drying and removing excess moisture. If you open the window, moisture from outside enters the room, which can reduce the effectiveness of the drying function of the switched on device.
4. System load. If the window is open, there is a constant flow of air from outside. This can create additional load on the fan or compressor. All elements of the device will wear out faster, which will reduce its service life. As a result, the equipment may break down.

If you open the window while the air conditioner is running, a person risks reducing the efficiency of the system and increasing energy consumption.It is better to close windows and doors to prevent drafts. This will ensure more efficient operation of the equipment and maintain comfortable conditions.

So is it possible or not to open the window?

The decision whether to turn on the air conditioner when the windows are open in the room or not is made by the owner of the house or office. But experts advise taking into account several factors:

1. Purpose of use. If the device is used for cooling or maintaining a certain temperature, it is not recommended to open the window. This will allow heat from the street to penetrate, which will complicate the operation of the air conditioner.
2. External conditions. If it is very hot or humid outside, you should also not open the windows. This will allow heat or moisture to enter. In such cases, closing the window is recommended to maintain comfortable conditions.
3. Ventilation. If air circulation is necessary, opening a window may be worthwhile, especially if the unit is not equipped with a ventilation system. In this case, you can open the window for a short time to ventilate the room. But it is better to do this not with the air conditioner on.
4. Energy saving. If you open the window while the device is turned on, this may lead to increased energy consumption. If a person wants to save energy, it is recommended to close the window to keep cooled or heated air inside the room.

Having figured out why it is impossible to turn on the air conditioner when the windows are open, the person himself must decide whether to open the window or not. It all depends on the specific needs, external conditions, and purposes of using the technology. If you want to get the most out of your appliances, experts recommend keeping your windows closed.
