to quickly sense a rise in temperature and call for compressor operation.
This leads to short cycling of the unit, poor temperature control and a greatly reduced unit
life span.
Due to this scenario we recommend that you DO NOT install any capacity of Mini Split
in rooms of less than 100 Sq Ft in Size
Unit Location
Ensure that no obstacles to the air flow from the Indoor unit are within 10 feet of the unit,
be especially aware that Computer server units create an airflow baffle and can have the
same effect on airflow to and from the unit as a small room size.
In Computer room application the
DuctlessAire
Mini Split units must be installed a
MINIMUM of 6ft from the floor so that the airflow from the unit is unimpeded.
Sensible Heat and Humidity
DuctlessAire
units are designed to provide an approximate SHR of 0.66. Be aware that
low humidity conditions will further reduce unit performance, requiring either additional
higher fan speeds to be programmed into the unit, or introduction of some latent load into
the room, e.g. Use of a humidifier.
Compressor Run Times
To ensure compressor longevity it is paramount that the compressor run time be longer
than 5 minutes at all times throughout the year . This will allow oil return to the
compressor, and will ensure that the max number of starts per hour is not exceeded.
If the compressor runtime is less than 5 minutes, especially at design ambient temperature
it is very likely that the unit is oversized.

The other major issue with Computer or Data rooms is that they are designed to operate
