HVAC

We design custom electric motors for multiple applications

Currently HVAC is powered by fossil fuels or a number of different types of electric motors, depending on the nature of the system and the type of installation. From HVAC in buildings to HVAC in vehicles, the pressure is on to improve efficiency and minimise emissions.

Looking purely at the HVAC in buildings, market research predicts the sector is set to double in size between 2020 and 2027. At the same time, estimates suggest HVAC accounts for 40% of overall energy consumption in developed countries.

Nearly all non-fossil fuel HVAC systems rely on electric motors and controllers. Ask ETA about their new technology offering compact, efficient, price competitive solutions tailored to the needs of the HVAC sector.

Our ETA motor

Possible applications

Currently there are a number of electric motors in use in HVAC - Permanent Split Capacitor motors which only offer 65% efficiency, CSIR (Capacitor-Start Induction-Run) motor, the CSCR (Capacitor Start Capacitor Run) and Split phase motors, as well as brushless DC motors.

The ETA motor and controllers offer significant improvements for applications that currently use brushless DC motors. ETA offers 95% motor efficiency and 98% controller efficiency at a lower cost and with future-proof capabilities for smart buildings and smart cities.

Efficiency is the key to electrifying HVAC without impacting on performance. From chillers in electric vehicles to quiet heating in caravans and zero-emissions from buildings, the ETA motor and controller can be adapted to your application.

Caravans

Compact, efficient electric motors allow for small, clean AC and heating systems. No noise, no fumes and longer intervals between battery charges.

Marine

Marine HVAC typically relies on pumping air or cooled water around the vessel, or a split-gas system. Heating systems are driven by the internal combustion engine. The ETA motor and controller offer higher levels of efficiency for both heating and cooling, without fumes or noise.

RVs

Electric heaters offer an excellent alternative to propane heaters which are typically only 70% efficient. They offer a zero emission, low noise alternative and can offer greater control over the areas of the RV that get heated.

Off Highway vehicles

As cabs get bigger, more glass is used (wraparound glass, vista windows, condo sleepers) and this makes it more challenging to keep the internal climate comfortable. Switching to a highly efficient electric HVAC system lets manufacturers of OH vehicles offer their customers the best of all worlds.

Domestic and commercial property (AEC)

Demand for energy-efficient, zero-emissions HVAC is growing as countries and individual cities strive to meet their sustainability targets. Switching to electric HVAC systems, making wider use of heat pumps and reducing reliance on fossil fuels is a cornerstone to delivering improvements.

New generation electric motor

Reduce the use of rare earth materials by circa 60%, increase the cross sectional area of copper used without generating negative eddy currents and reduce the use of laminated motor iron by circa 60% to 70%.

Controller performance without compromise

ETA motors and controllers provide the opportunity to reduce the costly stored energy through a greater understanding of duty cycles. 98% motor controller efficiency allows OEM’s to choose between a smaller battery (and thus lower cost) with similar range to today’s offerings or similar battery output and extended range.
