VN-U_S-E

Indoor‑side air heat exchanger designed to expand Toshiba VRF system flexibility and application scope
The Toshiba VN‑U_S‑E IDU Side Air Heat Exchanger is engineered to integrate seamlessly with Toshiba VRF indoor unit systems, enabling efficient air‑to‑refrigerant heat exchange for specialized and extended applications. Compact, reliable, and fully compatible with Toshiba VRF architecture, it enhances system adaptability while maintaining performance and control integrity.

Features

  • Energy Savings

    Recovers air suction heat and humidity up to 75% and transfers them to the outdoor fresh air. The unit has the ability to automatically change the operation mode of the airflow between heat exchanger mode (energy recovery) to normal standard ventilation mode (free cooling), based on the outdoor temperatures. Free cooling - Provides fresh outdoor cool air to reduce the indoor air temperature, when the outdoor temperature is lower than the indoor air-conditioned temperature.
  • Multi Application

    9 models available with air fl ow ranges from 150 to 2000 m3 /h. Air balance volume rate can be varied to suit the usage environment and location. Version with humidifi er is available for applications where humidity levels need to be controlled.
  • Fully Integrated

    Air conditioners and heat exchangers are controlled with the same main bus system (TCC-LINK).
  • Efficient Air‑to‑Refrigerant Heat Exchange

    Optimized heat exchanger construction supports effective thermal transfer while maintaining system efficiency.
