Air-to-Air Heat Exchanger

Toshiba’s VN model uses exhaust air to pre-condition the incoming air, thus reducing the cooling or heating load on the system. This allows the overall capacity size of the system to be reduced.

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 air fl ow 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.


  • 9 models are available with airflow ranges from 150 to 2000 m3/h.
  • Air balance volume rate can be varied to suit the usage environment and location.
  • Horizontal or upside-down installations.

Fully integrated

  • Air conditioners and heat exchangers are controlled with the same main bus system (TCC-LINK).
