Overview

Description

The demand for 7kW+ smart heat pump systems is growing, particularly in regions with strict energy efficiency regulations and high energy costs. Consumers and businesses are seeking sustainable, cost-effective HVAC solutions. Larger-capacity systems, like those above 7kW, are ideal for multi-family homes, commercial buildings, and larger residential applications that require significant heating and cooling loads while maintaining energy and cost efficiency.

This commercial and residential smart heat pump design features a comprehensive high-power synchronous/BLDC motor for driving air-to-water heat pump fan and compressor motors, supporting up to 10.5kW of power from a 3-phase Y-connected power main. It integrates a robust energy management control unit with eAI processing power, offering various options for wireless connectivity, HMI, and environmental sensors, enabling smart control and predictive maintenance capabilities.

System Benefits:

  • Complete heat pump outdoor unit with compatible components ensures optimal performance and easy installation.
  • Fully integrated, high-performance, cost-optimized dual motor control system for precision compressor and fan RPM/torque control with optional AI/ML enhancements (Reality AI) delivers high performance, cost efficiency, and precision control while allowing for AI-driven future optimizations.
  • Pressure sensor in the heating/cooling refrigerant optimizes the process and shuts off in case of low pressure.
  • Optional value-added features include air quality sensors for O3/NO2, temperature, and humidity for scalable design.
    • Arduino Nicla Env sensor board provides a ready-to-use module integrating multiple environmental sensors.
  • Rich connectivity:
    • Wi-Fi, Bluetooth®, and optional LTE-M/NB-IoT for IoT communication.
    • External control unit exchanges parameters with the heat pump or controls it via Digital I/Os, CAN bus, USB2.0 I/F, and Bluetooth.
  • High-end variant adds additional peripheral interfaces and performance features:
    • Ethernet and I3C interfaces.
    • MIPI DSI interface for high-end displays.
    • Additional onboard flash/SRAM for higher-performance applications.
