As an indispensable electrical equipment in modern home and office environments, air conditioners have a variety of functions, among which dehumidification and cooling are the two most common functions. Especially in the southern summer, the hot weather is often accompanied by ultra-high humidity, and the humid and hot weather is even more uncomfortable.
It is worth mentioning that dehumidification and refrigeration can reduce the indoor temperature and reduce the humidity of the indoor air, but they have significant differences in principle and effect. There are also some people who say that "using air conditioners to dehumidify and cool down is more energy-saving" and so on, in fact, these statements are one-sided.
So what is the difference between air conditioning dehumidification and refrigeration? Which is colder dehumidification 26 and refrigeration 26? If you don't understand, I recommend taking a look first!
1. The difference in the principle of air conditioning dehumidification and refrigeration
1. Refrigeration principle
The refrigeration function of an air conditioner is mainly achieved through the circulation of refrigerant between the compressor, condenser, expansion valve and evaporator. The compressor compresses the refrigerant into a high-temperature and high-pressure gas, which is then delivered to a condenser for heat dissipation, turning it into a high-pressure liquid.
The high-pressure liquid then enters the evaporator through the expansion valve, where it rapidly evaporates and absorbs the heat in the room, thereby reducing the room temperature. Finally, the refrigerant returns to the compressor again to complete the cycle.
2. Dehumidification principle
The dehumidification function of the air conditioner is achieved by reducing the dew point temperature of the indoor air. When the indoor air passes through the evaporator, the water vapor in the air will condense into water droplets on the surface of the evaporator, thereby reducing the humidity of the indoor air. At the same time, since the evaporator absorbs indoor heat during the refrigeration process, the dehumidification function will reduce the humidity and reduce the indoor temperature.
While dehumidification and refrigeration work similarly, they work with different goals and therefore have different results. The main purpose of the refrigeration mode is to cool down quickly, while the dehumidification mode focuses more on the rapid removal of moisture from the air.
Second, the difference between the effect of air conditioning dehumidification and refrigeration
1. Refrigeration effect
The main purpose of the refrigeration function is to lower the indoor temperature and make a person feel cool and comfortable in hot weather. When the refrigeration temperature is set to 26 degrees, the air conditioner will continue to work until the indoor temperature drops to about 26 degrees. In the process, the humidity of the indoor air may still be high, giving it a stuffy feeling.
2. Dehumidification effect
The main purpose of the dehumidification function is to reduce the humidity of the indoor air and make people feel dry and comfortable in a humid environment. When the dehumidification temperature is set to 26 degrees, the air conditioner will try to keep the indoor temperature at about 26 degrees while reducing the humidity. However, it is important to note that the room temperature in dehumidification mode may be slightly lower than in refrigeration mode because the evaporator absorbs indoor heat during dehumidification.
The experiment proves that in the dehumidification mode, the air conditioner runs in a low wind speed mode, when the room temperature is 20 °C ~ 30 °C, the dehumidification will be relatively energy-saving, and when the room temperature exceeds 30 °C, there is almost no difference in power consumption.
3. Which is colder between dehumidification 26 degrees and refrigeration 26 degrees
Before answering this question, we need to be clear: temperature is a relative physical quantity that describes the degree of thermal motion of an object. During the operation of the air conditioner, whether it is dehumidification or refrigeration mode, as long as the temperature is set to 26 degrees, the air conditioner will strive to maintain the indoor temperature at about 26 degrees.
So which is colder 26 degrees for dehumidification or 26 degrees for refrigeration? Although the temperature is 26°C, due to the difference in the working principle of the air conditioner, in the dehumidification mode, because the evaporator will absorb indoor heat during the dehumidification process, the lower the humidity, people will feel cooler at the same temperature.
Fourth, how to choose the right air conditioning mode
The choice of air conditioning mode should be based on the actual conditions of the room. In dry and high temperatures, the refrigeration mode can quickly cool the room; In a humid and stuffy environment, you can turn on the dehumidification mode to reduce the humidity first, and then switch to the refrigeration mode.
Especially at night, although the temperature may not be high, the humidity may be high, and the dehumidification mode can be used to better regulate the indoor temperature and humidity. In refrigeration mode, the air conditioner will actively reduce the temperature, which has a significant effect; In dehumidification mode, although the cooling rate is slightly slower, it performs better in removing excess moisture.
Therefore, when buying an air conditioner, try to choose an air conditioner with independent dehumidification function, which is very practical when the weather is particularly humid. Here are also recommended air conditioners with independent dehumidification function, which are cost-effective and have a recognized reputation!
1. Midea air conditioner is cool and power-saving
The Cool Energy Saving Series is one of the best-selling models of Midea's air conditioner, which adopts the latest energy-saving and power-saving strokes, reducing energy consumption by 25% and the APF energy efficiency ratio is as high as 5.30. It has many practical functions such as anti-direct blowing design, independent dehumidification function, light-off and screen-off mode, mobile phone power inquiry, and 56°C high temperature self-cleaning.
In terms of hardware configuration, Midea's cool power-saving series air conditioners are also not far behind. It is equipped with high-end components such as a Meizhi dual-rotor compressor, a 1.6-row condenser and a Sanhua electronic expansion valve to ensure the efficient and stable operation of the air conditioner.
2. Gree air conditioner Yunjia
Gree is the first brother of air conditioning, product quality and service have nothing to say, among which the Yunjia series is one of the best-selling classic models of Gree air conditioner, which has been in the forefront of the industry sales for many years. The air conditioner is equipped with a 9.8cc displacement Lingda compressor, 1.6 rows of condensed copper pipes and an electronic expansion valve, with an APF value of 5.27.
