Air Conditioning Mode Classification
At present, there are several main modes of air conditioners on the market:
Refrigeration mode: As the name suggests, refrigeration mode is the most commonly used mode of air conditioners to lower the indoor temperature and bring coolness to the hot summer months.
Heating mode: The heating mode, as opposed to the cooling mode, is used to raise the indoor temperature and provide warmth to the room during the cold winter months.
Dehumidification mode: The dehumidification mode is mainly used to reduce indoor humidity, which is suitable for humid and stuffy environments, which can effectively improve air quality and prevent mold growth.
Air supply mode: The air supply mode does not cool or heat, but simply blows indoor air, which can play the role of air circulation.
Automatic mode: Automatic mode is the intelligent mode of the air conditioner, which can automatically adjust the cooling or heating mode according to the temperature difference between indoor and outdoor, without manual switching.
The principle of different modes
Refrigeration mode: In refrigeration mode, the air conditioner compresses the refrigerant into a high-pressure gas through a compressor, and then dissipates heat through the condenser to turn it into a high-pressure liquid. After the high-pressure liquid enters the evaporator, it absorbs the heat in the indoor air and becomes a low-pressure gas, and finally returns to the compressor through the expansion valve to complete a refrigeration cycle.
Heating mode: The heating mode is similar to the cooling mode, but the refrigerant flows in opposite directions. The compressor compresses the refrigerant into a high-pressure gas, which is then dissipated through the condenser and turned into a high-pressure liquid. After the high-pressure liquid enters the evaporator, it releases heat and turns into a low-pressure gas, and finally returns to the compressor through the expansion valve to complete a heating cycle.
Dehumidification mode: In dehumidification mode, the air conditioner absorbs the moisture in the indoor air through the evaporator, condenses into water droplets, and then discharges it outdoors through the drain pipe. At the same time, the air conditioner will send out dry air and reduce the humidity in the room.
Air supply mode: In air supply mode, the air conditioner simply blows indoor air and does not participate in the cooling or heating process.
Automatic mode: In automatic mode, the air conditioner will automatically adjust the cooling or heating mode according to the temperature difference between indoor and outdoor. When the indoor temperature is higher than the set temperature, the air conditioner enters the refrigeration mode; When the indoor temperature is lower than the set temperature, the air conditioner enters heating mode.
Advantages and disadvantages of different modes
Refrigeration mode: advantages: good refrigeration effect, can quickly reduce the indoor temperature; Disadvantages: large power consumption, long-term use can easily lead to air conditioning disease.
Heating mode: Advantages: good heating effect, can quickly increase the indoor temperature; Disadvantages: large power consumption, long-term use can easily lead to air conditioning disease.
Dehumidification mode: advantages: can effectively reduce indoor humidity and improve air quality; Disadvantages: Poor refrigeration effect and large power consumption.
Air supply mode: advantages: no power consumption, can play the role of air circulation; Disadvantages: Inability to regulate the indoor temperature.
Automatic mode: advantages: intelligent and convenient, no need to manually switch modes; Disadvantages: High power consumption and may not meet special needs.
Specific usage scenarios
Hot summer: The first choice is the cooling mode, set the temperature to 26-28, which can not only achieve the cooling effect, but also avoid air conditioning diseases.
Cold winter: the first heating mode, set the temperature to 18-20, which can not only achieve the heating effect, but also avoid too much drying indoors.
Humid and stuffy environment: The first choice is the dehumidification mode, which can effectively reduce the indoor humidity and improve the air quality when used with the air supply mode.
Spring and autumn transition season: the preferred air supply mode, which can play the role of air circulation and avoid indoor air pollution.
Special needs: If you need to cool down or heat up quickly, you can use the automatic mode temporarily, but be aware of the high power consumption.
Precautions
Avoid using the air conditioner for a long time: Using the air conditioner for a long time can easily lead to air conditioning sickness, so it is recommended to open the windows for ventilation every once in a while.
Regular cleaning of the air conditioner: The air conditioner filter and evaporator are prone to accumulate dust and bacteria, and regular cleaning can ensure the cooling or heating effect of the air conditioner and avoid indoor air pollution.
Choose the right number of air conditioners: If the number of air conditioners is too small, the cooling or heating effect is poor; The number of air conditioners is too large, which is easy to cause waste. Generally speaking, a 10-square-meter room can choose 1 HP air conditioner.
Reasonable use of timer function: The timer function can avoid the long-term operation of the air conditioner and save electricity.
Conclusion
The right choice of air conditioning setting mode has an important impact on comfort, health and energy saving. By understanding the principles, advantages and disadvantages of different modes and specific usage scenarios, we can choose the right mode according to our actual needs and enjoy the coolness or warmth brought by the air conditioner, while avoiding unnecessary health problems and energy waste.
