A Sensible Heat Recovery Exchanger is an energy-efficient device designed for air-to-air heat exchange, recovering only sensible heat based on temperature difference, without any moisture or humidity transfer. It is widely used in ventilation systems, industrial exhaust air treatment, drying processes, and fresh air applications, providing effective energy recovery while maintaining complete air separation.
Sensible heat recovery exchanger
Working Principle
The exchanger utilizes a metallic or composite heat exchange core that allows high-temperature exhaust air and low-temperature fresh air to flow through separate channels. Heat is transferred through the heat exchange surfaces without air mixing, preheating or precooling the incoming air and significantly reducing heating or cooling loads.
Key Features
Sensible heat recovery only, no moisture transfer
Complete separation of air streams, no cross-contamination
High heat transfer efficiency and stable performance
Compact structure, easy system integration
Suitable for high-temperature, high-humidity, and corrosive air conditions
Materials and Structure
The heat exchange core can be manufactured from aluminum foil, stainless steel foil, or other corrosion-resistant materials. Structural configurations include cross-flow, counter-flow, or multi-pass designs, tailored to specific application requirements.
Typical Applications
Industrial fresh air and exhaust ventilation systems
Waste heat recovery from drying equipment exhaust
Spray coating, textile, and chemical process exhaust air
Energy storage cabinets and equipment cooling systems
Agricultural, livestock, and mushroom growing ventilation systems
Benefits
