As a means of reducing environmentally hazardous substances, we are reducing resource consumption and developing products that do not contribute to global warming. Examples of such activities include building a unified structure in every stage from production to collection and recycling of beds and reducing CO₂ through greater efficiency in GHPs. Moreover, to develop pioneering environmental technologies in energy related products, we are aiming for practical applications for residential fuel cell cogeneration systems.

Launch of GHP that reduces CO₂ emissions by approximately 16% (Aisin Seiki)

Aisin Seiki developed the E2 series GHP XAIR, the latest gas heat pump air conditioner (GHP^*1) model, jointly with Tokyo Gas Co., Ltd., Osaka Gas Co., Ltd., and Toho Gas Co., Ltd., and released it in the market in July 2011.

The product boasts high energy efficiency by an annual performance factor of 2.28^*2, and reduces CO₂ emissions by approximately 16%^*3 compared to the D series launched in 2007.

*1 Gas engine driven heat pump (GHP): An air conditioner in which the compressor is driven by a gas-fuelled engine.
*2 According to energy consumption per unit time calculation standards formulated in JIS B 8627
*3 For a 45 kW multi-type for large buildings. See below for estimation conditions.
