The basic functions of air conditioning: cooling, heating, dehumidification, and air purification.
1. Cool down
In the design and manufacture of air conditioners, it is generally allowed to control the temperature between 16 and 32°C. If the temperature is set too low, on the one hand, unnecessary power consumption will be increased, and on the other hand, when the temperature difference between indoor and outdoor is too large, people cannot quickly adapt to temperature changes when entering and leaving the room, and they are likely to catch a cold.
The air conditioner is accompanied by dehumidification during the refrigeration process. The relative humidity of the environment that people feel comfortable should be around 40-60%. When the relative humidity is too high, such as above 90%, even if the temperature is within the comfortable range, people still feel bad.
3. Heating up
Both heat pump type and electric heating type air conditioners have a heating function. The heating capacity gradually becomes smaller as the outdoor ambient temperature drops. If the temperature is at -5°C, it can hardly meet the heating requirements.
4. Purify the air
The air contains a certain amount of harmful gases such as NH3, SO2, etc., as well as various odors such as sweat, body odor and bathroom odor. Purification methods for air conditioners include: changing fresh air, filtering, and using activated carbon or photocatalyst to absorb and absorb.
