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.
