In winter, heating is provided from under the floor, and in summer, cooling is provided from the ceiling, maintaining a comfortable indoor thermal environment year-round! Whole-house air conditioning and floor heating with a single air conditioner!
The "Passive Air Conditioner" is an air conditioning system that creates a comfortable thermal environment without being troubled by unpleasant drafts or indoor temperature differences. Installed in the attic of a house that incorporates elements of passive design, it maintains a comfortable indoor thermal environment year-round by providing heating from the floor in winter and cooling from the ceiling in summer through ducting. By planning the architecture and air conditioning equipment as a cohesive unit, both indoor and outdoor spaces are neatly integrated, and the hassle of daily maintenance is reduced to just one unit. This leads to a simpler and more comfortable lifestyle. 【Features】 ■ Insulation ■ Sunlight shading ■ Daylight utilization ■ Utilization of solar heat and natural wind ■ 24-hour operation to reduce temperature differences * For more details, please download the PDF or feel free to contact us.
