Overview

Description

Heat pumps offer the most energy-efficient and environmentally friendly approach to providing heating and cooling in various applications. They extract heat from sources such as air, water, or ground to raise the temperature of water or air for domestic heating or sanitary hot water. Utilizing the energy transfer process based on the Carnot cycle (similar to a reversed refrigerator), heat pumps can achieve an electric energy efficiency of up to 400%.

This system combines a comprehensive high-power synchronous/BLDC motor design for driving air-to-water heat pump fan and compressor motors. It also integrates a robust and versatile energy management control unit with eAI processing power, offering various options for wireless connectivity, HMI, and environmental sensors. These features enable smart control and predictive maintenance capabilities.

System Benefits:

  • Complete heat pump outdoor unit.
  • Fully integrated, high-performance, and cost-optimized dual motor control system for precision compressor and fan RPM/torque control with optional AI/ML future enhancement (Reality AI)
    • raw data provided from the high-power 10.5kW motor control board,
    • eAI processing in the MCU based on the Arm® Cortex®-M85 core with Helium™ technology for acceleration ML tasks.
  • Pressure sensor in heating/cooling refrigerant to optimize the process and shut off in case of too low pressure.
  • Variety of optional value-added features, such as an air quality sensor for O3/NO2, temperature, and humidity.
  • Rich connectivity:
    • Wi-Fi, BT, and optional LTE-M/NB-IoT for IoT communication,
    • External control unit that can exchange parameters with a heat pump or control it via Digital I/Os, CAN Bus, USB2.0 I/F, Bluetooth,
    • Ethernet, Wi-Fi, and LTE-M/NB-IoT for cloud connectivity,
    • High-end GUI with MIPI DSI interface.
