[0002] The central air conditioning system consists of one or more cold and heat source systems and multiple air conditioning systems. This system is different from traditional refrigerant air conditioning. It centrally processes air to meet comfort requirements and uses the principle of liquid vaporization refrigeration to provide the required cooling 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 heating and cooling loads of the indoor environment. Long-term operation of central air conditioning will cause the equipment to be clogged with scale, which will reduce efficiency, increase energy consumption, and shorten lifespan, so it needs to be cleaned regularly.

[0003] It is difficult to control the dosage of the descaling agent added to the water tank of the existing central air conditioner descaling device when descaling the interior of the air conditioner, resulting in excessive or insufficient dosage of the descaling agent affecting the cleaning of the interior of the central air conditioner. When the ground where the descaling device is located is uneven, the water tank will tilt to one side and the water in the water tank will flow out. Therefore, a central air conditioner descaling device is proposed to solve the above-mentioned problems. Utility Model Content
