Researchers at Saratov State Technical University (SSTU) led by Yu.A. Gagarin have developed a room ventilation device designed to cut heating costs by reclaiming heat and moisture from exhaust air. This invention, reported by TASS, focuses on enhancing the efficiency of indoor climate control while reducing energy expenses.
The core principle involves boosting the supply air with heat and moisture drawn from the building’s exhaust air. By transferring heat back into the incoming air, rooms retain warmth more effectively, enabling lower heating usage without sacrificing comfort. The inventors claim that this technology could eventually eliminate heating charges for end users in appropriate settings, provided the structure has adequate insulation, sufficient lighting, and other heat sources. Under such conditions, electricity would be the primary ongoing expense rather than gas or boiler-based heating costs.
Capability of deployment spans various building types, including residential blocks, administrative offices, and industrial facilities. If adopted on a wide scale, this system has the potential to replace or supplement conventional central heating networks, offering an alternative path to energy-efficient climate control in large-scale structures.
Beyond heat exchange, the device also facilitates moisture exchange between exhaust and supply air through capillary porous moisture pipes. This feature helps maintain comfortable humidity levels, preventing the air from drying out as ventilation cycles operate. The researchers note that optimal humidity can vary among occupants and may fluctuate within a practical range, yet the system aims to preserve a conducive indoor climate for most users.
