Airxcel, Inc’s Coleman-Mach brand recently developed a series of DC direct air conditioning units in 48-volt and 24-volt models. The company said 12-volt models were coming soon.
Airxcel stated the air conditioners require DC direct wiring, bypassing the need for a DC to AC inverter. Bypassing the inverter saves battery life by as much as 20%, Airxcel stated, due to the power loss incurred when converting from direct to alternating current.
“As the leader in RV air conditioners, Coleman-Mach has long been at the forefront of energy conscious design,” said David Gehlen, product manager. “In fact, that is where our products shine.”
For Airxcel’s Coleman-Mach OEM partners, DC direct air conditioner options provide opportunities to improve performance in gas, diesel or electric powered coaches, Airxcel stated, without having to make significant changes to the coach to accommodate the newest designs.
“Beyond the energy efficiency of individual products, we look holistically at energy use by considering the entirety of what being an EV friendly brand means,” Gehlen said. “While our Coleman-Mach 8 Ultra Low-Profile shroud leads in aerodynamics and our Maxxair AC model is the lightest available roof top AC in its category, we continue exploring new ways to lessen drag.”
