Descriptions:

1 — Stirring fan;                                                                            2 — Circulating fan;

3 — Test prototype;                                                                       4 — Pollutant detection device;

5 — Pollutant generation device;                                                 6 — Air filter;

7 — Air supply valve of test chamber;                                         8 — Air supply of constant temperature and constant humidity                                                                                                            air conditioner (air supply in air exhaust) for test chamber;

9 — Air duct reversing valve (for converting                             10 — Air return of constant temperature and constant humidity

       the air return paths 10 and 11);                                                  air conditioner for test chamber;

11 — Test chamber exhausting air to the                                   12 — Exhaust valve of test chamber; 

         outside (including air filter);             

13 — Door of test chamber;                                                           14 — Air inlet of constant temperature air conditioner for outer                                                                                                                 chamber;

15 — Air return opening of constant temperature                       16 — Door of outer chamber; 

         air conditioner for outer chamber;

17 — Sampling outlet and sample sending opening of test        18 — Regulated power supply. 

        chamber;

Placement of 30m³ purifier CADR test chamber:

Central position: ground type (on the ground), desktop type (on 700mm tabletop), wall mounted type (1800 mm from lower edge to ground), ceiling type (on 700mm tabletop).

If not specified, the placement type is classified according to the height of the air outlet: place the test prototype on the tabletop if the height of the air outlet is less than 700 mm; place the test prototype on the ground if the height of the air outlet is more than or equal to 700 mm.

 

Note: If the cleaning function is the auxiliary function, for air conditioner, the dehumidifier, the fresh air unit etc., it shall be tested in complete-product level, however, the relevant components with the cleaning properties are only required to be started, and other components are not required to be started.

Recommended cleaning methods of 30m³  CADR test chamber and equipment

Daily or frequently clean the optical instruments as required.

Daily clean all horizontal surfaces.

Mop the floor with the wet mop after use for 5 days.

Clean the inner wall of the chamber after use for 20 days.

If necessary, spray antistatic agent every 5 days or frequently to ensure good sensor grounding and data record.

If the detection of particulates, gaseous pollutants and microbes cannot be performed continuously, firstly clean the test chamber and then detect the pollutants, so as to prevent the cross-effect.
