KARIYA, Japan - Denso Corp. announced that it has begun testing industrial heat pump air conditioners using biodiesel fuel at its headquarters in Kariya, Aichi, Japan.

“Denso expects to significantly reduce carbon dioxide (CO2) emissions from industrial heat pump air conditioners by using biodiesel fuel,” said Kenji Ohya, senior managing director in charge of Denso Corp.’s Sales Group. “We aim to introduce biodiesel engine heat pump air conditioners for industrial use by 2010.”

In its testing, Denso is examining the system’s compatibility and durability when using biodiesel fuel, refined from cooking oil used at the company’s cafeterias, to power heat pump air conditioners. Denso estimates that a heat pump air conditioner using biodiesel fuel can reduce CO2 emissions by approximately 90 percent compared to the company’s conventional kerosene heat pump air conditioner, currently marketed only in Japan.

Denso said it is focusing on reducing CO2 emissions in all company activities, including product development, manufacturing, procurement, and distribution, to reduce its impact on global warming.
