Minimum volume of water admissible
in the installation (cooling mode)
The electronic control for the 30PH units incorporates an auto-adaptive control for the compressor operating time based on
the time set for anti-short-cycle.
This control reduces the number of times the compressor is started up and permanently adjusts the system’s thermal inertia,
favouring the reduction of the minimum volume of water in the installation.
The size of the buffer tank can also be decreased since the unit will be stopped for less time.

The calculation of the minimum water volume has been done for nominal EUROVENT conditions, only in cooling mode. This
value is applicable for the majority of refrigeration applications (group with fan-coil units).
Note: the buffer tan k is indispensable in installations that operate with a reduced volume of water (group with an air handling unit) or for industrial processes.
For applications with a heat pump, it is recommended that the buffer tank be used in order to maintain a stable temperature during the defrosting cycles.
