Can refrigeration units be used in central air conditioning systems to control indoor temperature and humidity?

Yes, refrigeration units can be used in central air conditioning systems to regulate indoor temperature and humidity. Central air conditioning systems typically rely on refrigeration units to provide cooling, reducing air temperature through processes such as compression and expansion to ensure a comfortable indoor environment. In some systems, the refrigeration unit is also combined with the air handling unit, and in addition to temperature control, humidity can be adjusted through humidification or dehumidification functions. This system is widely used in commercial buildings, office buildings, hotels and other places, which can effectively maintain indoor temperature within a comfortable range, while controlling humidity to avoid excessively dry or humid environments that affect living or working experience.
