Which two channels should be set at the centralized isolation point?

Isolation observation points should be provided with two channels of cleaning and pollution, and the two channels should not cross to prevent cross-pollution.

According to the relevant requirements of the state for centralized isolation places and the basic points of communication control in COVID-19, there are the following six basic requirements:

1, keep a certain distance from residential areas and away from water sources and water intake points.

2. There should be reception, evacuation and transshipment channels for isolating observers.

Because central air conditioning can't be used in centralized and isolated places, it needs natural ventilation.

4. The excrement and sewage of isolated observers shall be disinfected before being discharged into the municipal pipe network.

ventilation system

1, the ventilation at the isolation point shall ensure that the airflow follows the clean area → semi-polluted area → polluted area → outdoor downstream.

2. When using natural ventilation, turn on exhaust devices such as exhaust fans when necessary to enhance indoor air flow.

3. When the central air conditioner is ventilated, the fresh air outlet should be set at a clean outdoor air point, which is lower than the exhaust outlet, and short circuit cannot occur.

Run with fresh air, running 1 hour every day before or after the air conditioner is turned off; Air purification and disinfection devices should be installed and operated effectively; The air conditioning system with fan coil and fresh air shall ensure independent ventilation in each room; Open cooling towers, filters, tuyeres, air handling devices, surface coolers, heaters (humidifiers), condensing trays and other equipment and components should be cleaned, disinfected or replaced weekly.
