Hybrid battery heat exchanger (chiller)
Heat exchanger for heat pump operation with refrigerant receiver
Refrigerant pressure/temperature sender
The hybrid battery heat exchanger is a plate heat exchanger within
which the refrigerant evaporates. The component is used for
cooling the battery circuit and for extracting heat from the low-
temperature circuit during heat pump operation.
The heat exchanger for heat pump operation transfers heat from
the refrigerant circuit or the cooling circuit to the heating circuit.
This means that the hot, gaseous refrigerant condenses within the
plate heat exchanger and dissipates its heat to the heating circuit.
The sensors for refrigerant pressure and refrigerant temperature
(G395, G826 and G827) are used for regulating the cooling and
heat pump systems. The sensors evaluate the pressure and tem-
perature in the refrigerant circuit.

Note
The sensors for refrigerant pressure and refrigerant temperature currently have a fixed address. All three sensors are identi-
cal in design, but must not be interchanged. The part number, address and service component designation can be found on
the label marking the electrical connection.
