VRF With a Vision:
Trane^® / Mitsubishi Electric VRF and Ductless

Our VRF systems create a one-stop solution that includes Trane’s vast product portfolio, featuring Trane^® / Mitsubishi Electric VRF technology, combined with best-in-class engineering knowledge and support resources.

VRF system design does not need to be complicated. By evaluating these four design considerations, you can help ensure a successful VRF system design for any commercial building project.

Should the VRF System be a heat pump or heat recovery type?

Heat pump

A Heat Pump system provides either heating or cooling to all of the connected zones. Typically, these systems are applied to spaces that experience uniform load profiles.

Heat recovery

A Heat Recovery system can simultaneously cool or heat any connected zone by redirecting energy from one space to another.

Will the ventilation air be conditioned to a predetermined supply air temperature or to ensure adequate space humidity?

Space

Removing moisture from the ventilation air to a level that offsets both outside air and space latent loads. This strategy can decouple sensible and latent loads and allows the indoor terminals to manage sensible loads only.

Outdoor air

Removing moisture from the ventilation air to a level that only offsets the latent load from the outside air. This strategy requires the indoor terminals to manage the space latent loads.

Will the ventilation air be conditioned by an energy recovery ventilator (ERV) or a DOAS?

ERV

Passive air-to-air energy recovery. Transfers energy from the somewhat conditioned air leaving the building, to the unconditioned air entering the building.

DOAS

Active cooling, heating and dehumidifying devices that treat the outdoor air stream independently of the recirculated air stream

How will the system be controlled?

Integrated Controls

Uses one system to control and coordinate the operation of both the ventilation and VRF system.

Independent Controls

Separates ventilation system and VRF system control.
