The modular air conditioning unit is one of the primary air processing equipment, which does not include its own cooling or heating sources. It uses chilled water, hot water, or steam as the medium to complete a series of functions such as air filtration, purification, heating, cooling, humidification, dehumidification, noise reduction, and fresh air treatment, all in a combined cabinet unit.
New air enters the air conditioning unit, mixing with return air from indoors in the mixing section. The mixed air passes through the preliminary filtration section, removing dust and debris, then through the medium filtration section for secondary filtration, removing finer dust and debris. Next, it is cooled or heated through the cooling or heating section to reach the required temperature point, and then humidified to meet the system's humidity requirements in the humidification section, reaching the supply air condition point. Finally, the treated air is delivered to the indoor space through the fan section.
