Ductless Type 1 Ventilation System passiv Fan
Type 1 ventilation is not high.
<Resolving the Issues of Type 1 Ventilation All at Once> High-performance building materials such as insulation, resin sashes, and Type 1 ventilation are essential for energy-efficient homes, but the adoption of Type 1 ventilation has been slow. Reasons include "high electricity costs," "difficult duct installation," "limitations on space design," and "troublesome maintenance." However, with the introduction of the ductless passiv Fan, which boasts a heat exchange rate of 90%, all these issues have been resolved. ■ Electricity costs are about half of conventional Type 1 ventilation In a comparison of a 40-tsubo wooden house, the annual electricity cost for conventional Type 1 ventilation is about 8,000 yen. The passiv Fan has miniaturized the fan, significantly reducing power consumption to about 4,100 yen, which is half the cost. This is equivalent to the electricity cost of Type 3 ventilation. With a maximum heat exchange rate of 90%, the power consumption for air conditioning and other climate control systems is also greatly reduced. After deducting the savings in power consumption, maintenance costs, and utility expenses, it results in an annual net savings of 10,480 yen (according to manufacturer data). ■ Improved construction and design flexibility Since the Achilles' heel of Type 1 ventilation, "duct installation," is not required, construction and design flexibility have significantly improved. Being made in Japan, it is compatible with traditional and 2x4 construction methods. Additionally, compared to German products, it has higher quietness performance and is more compact.
