Heat exchange rate 90%! An eco-friendly ventilation system utilizing geothermal energy with excellent cost performance.
The "Sumika Eco Super Hybrid" is a central ventilation system installed under the floor that allows for healthy and efficient ventilation throughout the entire house. In summer and winter, it performs first-type total heat exchange ventilation, recovering heat and humidity through supply and exhaust air. During summer nights and the transitional seasons of spring and autumn, it automatically switches to a third-type ventilation system with low power consumption, utilizing exhaust fans and natural air supply. The ventilation method changes automatically according to the outside temperature, ensuring comfort and energy efficiency at all times! With a high-performance pollen filter that removes 99.8 percent of pollen, the air being drawn in is always clean. The dirty air expelled from indoors not only efficiently recovers heat and humidity for reuse but also effectively utilizes geothermal heat from beneath the floor, significantly reducing heating and cooling costs. It is an eco-friendly ventilation system that combines affordability, performance, and the ability to propose solutions to clients.

basic information
【Chomei Eco Super Hybrid Features】 ■ Summer Cooling Period During the day, exhaust air that has been cooled and dehumidified by the air conditioner exchanges heat and humidity with the incoming outside air. Since the incoming air is cooled and dehumidified, significant reductions in cooling costs are possible. At night, when the outside temperature is below 27°C, it automatically switches from type 1 total heat exchange to type 3 ventilation (natural intake), directly supplying cool air into the room. ■ Spring and Autumn Transitional Period During the transitional periods of spring and autumn, it maintains a comfortable living environment by utilizing type 3 ventilation to intake outside air without unnecessary heat exchange. ■ Winter Heating Period The high-performance total heat exchanger recovers heat and moisture from indoor exhaust air, warming and humidifying the cold incoming air in winter. This prevents excessive dryness indoors while reducing heating costs. 【For more details, please download the catalog or feel free to contact us】
