Technical Field

[0001] The utility model relates to the technical field of central air conditioners, in particular to a central air conditioner fresh air duct cleaning device. Background Art

[0002] The central air conditioning system consists of one or more cold and heat source systems and multiple air conditioning systems. It uses the principle of liquid vaporization refrigeration to provide the required cooling capacity for the air conditioning system to offset the heat load of the indoor environment. The heating system provides the required heat for the air conditioning system to offset the cooling and heating loads of the indoor environment.

[0003] Central air conditioners will accumulate dust in the air during daily use. Over time, a layer of dust will adhere to the fresh air duct. In subsequent use, the exhaust gas will carry some dust, causing floating dust in the limited space. This will not only affect the breathing safety of people in the space, but also reduce the quality of oxygen in the space. In addition, existing technology requires manual cleaning with ladders and cleaning equipment. Workers will quickly feel tired if they hold the cleaning equipment for a long time, thereby reducing the cleaning efficiency.

[0004] To this end, we have designed a central air conditioning fresh air duct cleaning device. Utility Model Content
