Description

Technical Field

[0001] The present invention relates to the technical field of air purification and treatment, and more specifically, to an online filter replacement device for a clean air-conditioning unit. Background Art

[0002] Purification air conditioning units are air handling equipment assembled from various air handling functional sections, suitable for air purification systems of various clean workshops, mainly suitable for air purification systems of various clean workshops. Usually, purification air conditioning units are composed of air handling functional sections including fresh air section, filtration section, refrigeration section, heating section, maintenance section, air supply section, flow equalization section, humidification section, secondary filtration section, and air supply section, to ensure that the temperature, humidity and cleanliness of the clean workshop are maintained within the required area. After a period of use, the dust holding capacity of the filtration section of the purification air conditioning unit reaches the upper limit and cannot effectively filter dust particles, so it needs to be replaced regularly.

[0003] The existing filter replacement method is to open the chassis door of the purification air conditioning unit and then replace the filter in the filter section. This operation requires the equipment to be shut down, or affects the air supply volume of the equipment and thus affects the pressure in the room, causing periodic pressure difference disturbance, thereby affecting the stability of the clean room.
