With the development of technology, air conditioning is no longer just a tool for adjusting room temperature, but integrates more functions. But when using it, you still need to pay attention.

      Why do I need to open a window for ventilation when I turn on the air conditioner?

           Not long ago, the topic of "Why do you need to open the window for ventilation when turning on the air conditioner" became a hot topic, and many netizens also expressed that it is not very comfortable to blow the air conditioner for a long time without opening the window. Why is this?
Let's start with the principle of air conditioning.
      Simply put, the interior of an air conditioner can be viewed as a circulating structure, in which the refrigerant flows continuously. We take the compressor as the starting point, and the refrigerant is first compressed into a liquid by the compressor. During this process, the refrigerant becomes in a high-temperature and high-pressure state, and then passes through the fan of the outdoor unit to cool the condenser. Then, the temperature drops rapidly through the expansion valve, and the evaporator absorbs a large amount of heat from the air and blows out cold air through the fan of the indoor unit. Heating reverses the system, with the outdoor unit absorbing heat and the outdoor unit dissipating heat.

       Do you understand? Unlike many people's first impressions, air conditioning is actually a closed system that can blow out cold air, but it cannot provide ventilation during operation. The copper pipe connecting the indoor and outdoor units is actually filled with refrigerant.
          When we turn on the air conditioner, we often close the doors and windows tightly for cooling purposes, which not only prevents air circulation, but also prevents the accumulation of toxic and harmful substances such as formaldehyde, benzene, TVOC, and carbon dioxide in the room from dispersing. If we do not pay attention to the hygiene of the room and the cleanliness of the air conditioner, the dust, mold, and other pollutants on the air conditioner filter can also affect human health.
         So, it is still necessary to open windows for ventilation when turning on the air conditioner.
Of course, opening windows for ventilation can affect the efficiency of air conditioning after all. It's okay in summer, but if it's winter for heating, the feeling of cold air pouring into the house is indeed quite uncomfortable. Here, it is recommended that families with conditions can open the window's up/down hanging function, only opening a small gap to achieve ventilation without affecting the air conditioning. For those without installing up and down hanging windows, they can open the window every few hours for 10-15 minutes, which can also improve air circulation.

In response to consumers' demand for air exchange during air conditioning, manufacturers have now introduced fresh air air air conditioners. As the name suggests, fresh air conditioning is a product that combines the effects of fresh air and air conditioning. When the air conditioning and fresh air are turned on simultaneously, it can not only blow cold air but also enjoy fresh outdoor air, which can be said to kill two birds with one stone.

As the most popular air conditioning category at present, most brands on the market have launched new air conditioning products, and the price has not significantly increased compared to traditional air conditioning. At present, the fresh air volume for hanging the machine is between 30-60m ³/ h. The fresh air volume of the cabinet can reach 100-200 meters ³/ h. The air exchange rate of the wall mounted fresh air fan isapproaching, and consumers can choose according to their needs.

The body temperature of newborns is already slightly higher than that of adults. For newborns, the most comfortable temperature is around 26 ℃ to 28 ℃. If the weather is too hot or too cold, it is easy to get sick. Adjusting the temperature through air conditioning can not only maintain the baby's physical health, but also help relieve emotions, making the mood more peaceful, and avoiding crying due to too cold or too hot. In addition, the noise caused by air conditioning operation is considered white noise for children, which can help them fall asleep quickly and smoothly.

Firstly, it is important to open windows in a timely manner for ventilation. Due to the fact that during air conditioning refrigeration, the indoor unit evaporator condenses the water vapor in the air to form air conditioning water (condensate) during heat absorption, the air will also become very dry if the air conditioning is kept on. And if the baby is in a too dry environment for a long time, it is easy to grow dander, rash, and even Nosebleed.

However, this feature of air conditioning can also be utilized. The weather in summer often becomes very humid, and when it warms up slightly, it becomes stuffy. Children with sensitive skin can also develop eczema. At this time, by turning on the dehumidification function of the air conditioner, it can quickly remove a large amount of moisture from the air through evaporation and condensation, allowing babies to stay away from the troubles of stuffiness and eczema.

Most importantly, if there are babies at home, it is important to pay attention to the daily cleanliness of the air conditioning. The evaporator and condenser of an air conditioner can produce water droplets, which can easily breed bacteria, such as Legionella, when mixed with dust and mold in the air, making it even more dangerous for children. Generally speaking, professional air conditioner cleaning personnel need to carefully clean the indoor unit before starting the air conditioner in summer and winter before it can be used.

In addition, many air conditioners now have self-cleaning functions, which are based on the principle of rapidly cooling the evaporator to frost, and then defrosting and rinsing off the dust and dirt attached to the evaporator fins. If equipped with the self-cleaning function of the outdoor unit, it is necessary to flush the fins of the evaporator (condenser) of the outdoor unit in the heating mode to improve the working efficiency of the air conditioning.

If consumers pursue healthy ventilation, they can also choose air conditioners with UV ultraviolet sterilization function. This type of air conditioner is equipped with an ultraviolet lamp next to the evaporator to disinfect the air and effectively prevent bacterial growth. It should be noted that UV sterilization cannot prevent dust accumulation, and it should still be used in conjunction with self-cleaning function.
