DAIKIN IS A global HVAC and refrigeration manufacturer and developer that produces systems that often weigh close to a ton. Creating such massive systems requires Daikin to determine ways to minimize its environmental impact by creating efficient products and reducing waste and GHG emissions.
Daikin has stepped up to the plate, offering a number of innovative products produced sustainably to limit its impact on the environment.
Energy-Efficient Inverter Technology
Daikin is pioneering an inverter-based compressor technology, which controls motor speeds to eliminate unnecessary operation. Air conditioners with compressors save 30 percent more energy than traditional air conditioners.
“They typically operate on an on-off scenario,” says Marc Bellanger, director of marketing and communications for Daikin North America. “An inverter compressor operates at variable speeds or capacities, and in doing so it only delivers the amount of cooling or heating needed based on ambient condition or load in the space.”
The compressor works using a permanent magnet with a natural magnetic force and an electromagnet. The north and south ends of the electromagnet are determined by the direction of the electric current. When the north and south ends of the magnets meet, they attract. When the north ends or south ends of the magnets meet, they repulse. Then, the inverter rotates the motor by switching the direction of the electromagnet’s electric current.
New Refrigerant to Reduce Energy
Daikin also recently released the first residential-use air conditioner using R-32, a new refrigerant that can carry heat more efficiently to minimize damage to the environment. R-32’s global warming potential is one-third lower than R-22 and R-410A, both commonly used refrigerants. It also reduces electricity consumption by 10 percent compared to R-22.
