Fresh Air System with Total Heat Exchange Technology

The core objective of the heat and moisture exchange technology in fresh air systems is to recover energy during the ventilation process, thereby reducing building energy consumption for temperature control. This technology utilizes total heat exchange, meaning it simultaneously recovers both sensible heat (temperature) and latent heat (humidity) from the exhaust air.

Core Principle

The physical basis is the principle of heat and mass transfer, specifically implemented through a core component called a "total heat exchange core." This component is made of a material with a specific microporous structure, forming dense, parallel, and mutually isolated tiny airflow channels. During operation, outdoor fresh air and indoor exhaust air flow through these adjacent channels in opposite directions. Due to the temperature difference, heat is conducted through the solid wall from the high-temperature side (such as exhaust air in winter) to the low-temperature side (fresh air); due to the water vapor partial pressure difference, water molecules diffuse through the material's micropores from the high-humidity side to the low-humidity side. This process is a bidirectional, simultaneous dynamic transfer; the two air streams do not mix, but energy and matter are exchanged.

Functions and Advantages of Ceramic Cores

In the total heat exchange core, the ceramic core, as a high-performance solution, demonstrates its functions and advantages through its material properties:

Efficient Mass Transfer Carrier: Its precisely controlled microporous structure provides efficient diffusion channels for water vapor, enabling effective humidity transfer.

Stable Heat Transfer Medium: Ceramic material has good thermal conductivity, ensuring efficient heat transfer.

Excellent Durability: Ceramic material is chemically stable, corrosion-resistant, and its inorganic nature makes it less susceptible to mold growth, resulting in a much longer service life than paper or polymer membrane cores.

Wide Environmental Adaptability: It can withstand harsh conditions such as high and low temperatures, high humidity, and condensation/freezing, making it suitable for extreme climate regions.

Therefore, the ceramic core is essentially a solid-state energy exchange medium that simultaneously possesses efficient heat conduction and water vapor permeability, allowing the energy from the exhaust air to be recovered and used to pre-treat the fresh air.

Main Applications and Benefits

Fresh air systems equipped with total heat exchange cores (especially ceramic cores) are mainly used in scenarios with high requirements for indoor air quality and energy efficiency:

High-end Residences and Public Buildings: While continuously providing fresh air, it significantly reduces the load of cooling in summer and heating in winter. Professional environments such as medical facilities and laboratories:  While ensuring strict ventilation rates, the system achieves energy savings, and its antibacterial properties meet hygiene requirements.

Buildings in extreme climate regions: Its weather resistance ensures stable and long-lasting operation of the system in areas with extreme cold or high temperature and humidity.

The core benefit of this system is energy saving. By recovering exhaust air energy, the temperature and humidity of the incoming fresh air can be pre-treated to closely match indoor conditions, typically reducing the energy consumption of the building's air conditioning system by more than 40%, while maintaining comfortable and stable indoor temperature and humidity.

Summary

Ceramic core total heat exchange technology efficiently recovers exhaust air energy through physical means, making it key to achieving energy-efficient ventilation in fresh air systems. Thanks to its durable, stable, and healthy properties, ceramic material is the ideal carrier for the high-end, long-life development of this technology. We are a Chinese industrial ceramics manufacturer.
