The main modules and functions of combined air conditioning units

Combined air conditioning unit it is a master of modern air conditioning technology. It is composed of multiple functional segments, each of which has its own unique role and works together to achieve comprehensive air treatment. The following are the main modules of combined air conditioning units and their functions:

Fresh air section:

Function: Responsible for introducing fresh air from the outside, providing sufficient fresh air volume indoors, and ensuring the freshness and quality of indoor air.

Features: The fresh air outlet is usually equipped with an air volume regulating valve to adjust the fresh air volume as needed.

Return air section:

Function: Used to connect the air duct and recover part of the air in the room. This part of the air is processed and then returned to the room to achieve air recycling and improve energy efficiency.

Features: The return air section is also equipped with an air volume regulating valve to control the return air volume.

Mixed air section:

Function: Mix fresh air and return air in a certain proportion. This function is particularly important in scenarios where both fresh air and return air need to be used to adjust indoor temperature and humidity.

Features: The mixed air section usually has two air inlets, fresh air and return air, and is equipped with an air volume regulating valve to achieve flexible adjustment.

Filtration section (including primary filter section and medium and high efficiency filter section):

Function: Use filters of different levels to effectively remove dust, particles, bacteria, viruses and other impurities in the air, providing clean air indoors. The primary filter section mainly filters out large particles of dust, while the medium and high-efficiency filter sections can further filter out smaller impurities.

Features: The filter needs to be replaced or cleaned regularly to maintain its filtration effect.

Heating section and cooling section (or surface cooling section):

Function: Used for heating and cooling of air respectively to adjust indoor temperature. The heating section usually uses hot water, steam or electricity as the heat source; the cooling section reduces the air temperature through refrigerant circulation.

Features: These functional sections are usually equipped with automatic control systems to achieve precise temperature regulation.

Humidification section:

Function: Increase air humidity in dry environments and improve the comfort of indoor environments. Humidification methods can be dry steam humidification, high-pressure spray humidification or wet film humidification.

Features: The humidification amount can be adjusted according to indoor humidity needs.

To sum up, the various modules of the combined air conditioning unit work together to achieve comprehensive control of air temperature, humidity, cleanliness and freshness, thereby providing a comfortable and healthy indoor environment.
