Notes
1. Desuperheater water type heat exchanger ∆T = 10K.
2. The hydraulic and/or water type heat exchanger module must be must be protected against frost (option 41 or 42A or 42B) or the loop must be protected with by an
antifreeze solution for outdoor temperatures < 0 °C.
However, the customer is responsible for protecting the desuperheater water type heat exchanger water loop at outdoor temperatures below 0 °C
3. These ranges are guidelines only. Verify the operating range with the electronic catalogue.
Key
Operating range at full load
Extension of the operating range, 30RBP/RQP unit: frost protection required (see note 2).
Heating mode: part load at inlet air temperature between -10 and -15 °C.
Cooling mode: part load at inlet air temperature above 46 °C.
Limited desuperheater power.
Operating range at part load for RQ only with limited desuperheater power.
Potential load shedding before defrosting during the frosting cycle, depending on the humidity conditions.
Limited desuperheater power. Please refer to the selection in the electronic catalogue.
