Fig.2 is the combination view of the ODU of Modular DC Inverter Multi VRF System and the IDU

of Multi VRF System. IDU can be cassette type, one-way cassette type, wall-mounted type, duct type,

etc. When any one IDU receives operation signal, ODU will start to work according to the capacity;

when all IDUs stop, ODU will also stop.

2.4 The Range of Production Working Temperature

Cooling Ambient temperature: -5 ~52

Heating Ambient temperature: -20 ~24

When the indoor units are all VRF fresh air processor, the unit operating range is as follows:

Cooling Ambient temperature: 16°C~45°C

Heating Ambient temperature: -7°C~16°C

If the temperature is beyond the range, the safety protection measure of the unit may take effect,

and the air conditioning unit will stop.
