Note:

The above is the combination method for single heat exchanger, when multiple heat exchangers need to be

matched according to the capacity of each heat exchanger

Length

Pipe length between outdoot unit& AHU VALVE Min5m，max.50m

Pipe length between AHU valve & AHU Max.5m

Drop between outdoor unit & AHU valve ±30m

Drop between AHU & AHU valve ±5m

Note:

• Non-mixing connection: AHU connection rate 90 ~ 110%

• When mixing:

1. The total indoor unit connection rate is 50 ~ 110%, of which the air conditioner

internal unit is not less than 50%

2. A system can only be connected to an AHU and an AHU valve box
