Heat pumps can play a key role in climate change mitigation. They have a reversing valve that can move the heat from inside the house to the outdoors (cooling mode) or reverse the cycle and move the heat from outside the house to indoors (heating mode). The coefficient of performance (COP) is high for heat pumps. Renesas provides comprehensive solutions for heat pump control systems.

System Benefits:

  • High-performance and dedicated motor control MCU
  • Power line communication (PLC) and Wi-Fi modules provide stable wire or wireless communication
  • Multiple integrated sensors to monitor the system and optimize the operation




  • Heat pump
  • HVAC
