Embodiment 1

[0040] A method for eliminating harmful germs inside the ventilation duct of an air conditioning system, including completing the construction of the equipment system according to the following steps: air conditioning equipment units (including central air conditioning units, fresh air system hosts or air filtration and purification equipment, referred to as "equipment units") The main exhaust duct 1 is drawn from the return air outlet of the equipment unit and drawn and arranged along the direction of the incoming wind (against the airflow direction of the duct) to each floor of the building (it can be a single floor or multiple floors) and drawn out in each room. Several exhaust branch pipes with return air outlets (several are 2-1000); a ventilation branch pipe 3 is connected to the joint between the above-mentioned main exhaust duct and the return air outlet of the equipment unit, and the control valve 5 is connected to the ventilation branch pipe 3. The ventilation branch ...

Embodiment 2

[0051] A method for eliminating harmful germs inside the ventilation duct of an air conditioning system, including completing the construction of the equipment system according to the following steps: air conditioning equipment units (including central air conditioning units, fresh air system hosts or air filtration and purification equipment, referred to as "equipment units") The main air supply duct 2 is drawn from the air outlet of the equipment unit and installed along the air supply direction (along the airflow direction of the duct) to each floor of the building (it can be a single floor or multiple floors) and inside each room Lead out several air supply branch pipes with air outlets (several are 2-1000); set a ventilation branch pipe with control valve 6 at the joint of the main air supply pipe 2 and the air outlet of the equipment unit Pipe) 4, access an ozone generator 8 through this ventilating branch pipe;

[0052] 1) The main air supply pipe, air supply branch pip...

Embodiment 3

[0059] It is basically the same as Embodiment 1 and 2, the difference is that: step 3) choose to install electric heating and electric heating appliances in the air outlet cavity of each sending (returning) air branch pipe distributed in the airtight room, and the electric heating element whose insulation performance reaches the standard (such as electrothermal alloy wires or foil strips) are set in the inner cavity of each tuyere (or in the pipe connected to the tuyere); the electric control switch of the electric heating appliance for degrading ozone can be connected to the control cabinet of the ozone generator to realize the generation of ozone The linkage of the device can also be set independently in the room.

Abstract

The invention relates to a method for eliminating harmful germs inside a ventilation pipeline of an air conditioning system. The method for eliminating the harmful germs inside the ventilation pipeline of the air conditioning system is characterized in that a ventilation branch pipe with a control valve is connected to the butt joint position of the ventilation pipeline and an air conditioning equipment unit air opening, the ventilation branch pipe is used for being connected with an ozone generator, ozone degradation devices are installed in inner cavities of air supply and return ports of the air conditioning systems in related rooms, in the running gap of the air conditioning equipment unit, an ozone generator and ozone degradation devices in the inner cavities of the air supply and return ports are started, safe and efficient mechanical elimination operation for various germs adhering to a main ventilation pipeline, and the ventilation branch pipe and the inner walls of air inlet and outlets on the main air supply pipeline and the ventilation branch pipe is achieved.

Description

technical field [0001] The invention relates to a method for eliminating harmful germs inside a ventilation duct of an air conditioning system. Background technique [0002] The central air conditioner adjusts the indoor temperature through cooling and heating. The fresh air system uses the circulation of indoor and outdoor air to ensure indoor air quality and air freshness. The fresh air system sends outdoor air into the Indoors, the indoor air is discharged outside through the tuyere, exhaust pipes and fans. Through this ventilation, the turbid indoor air is discharged, and the outdoor fresh air is introduced to realize the circulation of indoor and outdoor air. [0003] However, with the acceleration of urbanization, a variety of epidemic diseases occur frequently in spring and winter, and face-to-face, shoulder-to-shoulder, shuttling and even close contact often occur in crowd gathering places, and various germs are carried in these scenes The potential source of risk o...
