A water-cooled condenser is part of a specific hot loop/cold loop thermal management architecture. It connects the cooling loop to the air conditioning system. This innovative condensers use coolant rather than air to liquefy air conditioning refrigerant vapour.
Battery cooling needs are increasing and require higher condensation performance. But a condenser needs also to work as an evaporator to recover heat from air at cold temperatures to avoid too much impact on the vehicle range.
It is a key exchanger in a heat pump loop to heat up the cabin. However, when the heat pump cannot provide enough heat, a High Voltage Coolant Heater is required.
