11.5 Limits of use
The maximum outdoor temperature (TA) for heat pumps of type OCHSNER AIR BASIC is defined as -20°C
with a maximum flow temperature of 50°C.
The maximum flow temperature (TWV) of the heat pumps is +55°C at => -15°C outdoor temperature.
Therefore,
a max. system temperature of 50°C is recommended when designing the system!
Limits of use for outdoor temperature:
•
for heating -20°C > OT < +35°C
•
for c15°C > OT < +35°C
