Indoor Unit Branch
Joint Assembly
On the choice of branch joints, refer to section "4.3.3
Selecting piping diameters".
3.3 Recommended Outdoor Unit
Combination
CAUTION
The total capacity of the IDU shall be
between
50%–130%
capacity of the ODU.
In the system where all indoor units are
running at the same time, the total capacity of
the indoor units should be less than or equal
to the combined capacity of the outdoor unit
to prevent overloading in poor operating
conditions or narrow operating space.
The total capacity of the indoor units can be
up to a maximum of 130% of the combined
capacity of the outdoor unit for a system
where not all the indoor units are operating at
the same time.
If the system is being used in a cold region
(ambient temperature is -10°C or below) or a
very hot, heavy-load environment, the total
capacity of the indoor units should be less
than the combined capacity of the outdoor
unit.
The heating capacity of the heat pump will
reduce
when
the
temperature is lowered. Therefore, when
installing a heat pump in an area with low
temperatures, it is recommended to use the
IDU with an auxiliary heater.
