Heat Exchanger Core Introduction

The heat exchange core is an energy-saving device used for energy recovery in air conditioning exhaust. Its main components include the housing, the heat exchange core, and the filter. Due to the use of materials with thermal conductivity in the heat exchange core, it can pre-cool and dry the incoming fresh air in summer and preheat and humidify it in winter when applied in air conditioning systems, significantly reducing the fresh air load. This, in turn, saves energy consumption of the cooling and heating systems, and is highly beneficial for small-scale systems in terms of reducing operating costs and peak electricity usage. The overall heat exchange efficiency is related to the structural characteristics of the heat exchange core, the air volume ratio of the two streams of air passing through the core, and the incoming air parameters.

Membrane-type air-to-air full heat exchanger (full heat exchange core)

The energy from indoor exhaust air can be utilized to pre-cool (or heat) the incoming outdoor fresh air, thereby reducing the energy consumption of the fresh air system. Implementing a full-heat exchanger in the central air conditioning system not only enhances indoor air quality but also effectively reduces the fresh air load, diminishes the installed capacity of cooling and heating source equipment, improves the efficiency of the air conditioning system, and saves operational costs.

To achieve both energy efficiency and comfort, a full heat exchanger that can perform heat exchange and ventilation simultaneously is highly required.

Right-angle intersecting sawtooth finned plate-to-plate air-to-air heat exchanger

A representative material for full heat exchangers, composed of specially processed partitions and spacers. The air flow paths for intake and exhaust are completely separated by partitions, ensuring that intake and exhaust air do not mix, thereby constantly maintaining the introduction of fresh external air. Through the special processing of paper in the full heat exchanger material, utilizing its thermal and moisture permeability properties, etc., heat transfer occurs during the temperature (sensible heat) exchange when exhaust and intake air pass through the full heat exchanger material; and using the vapor pressure difference of humidity (latent heat) to facilitate the full heat exchange through the specially processed paper of the partitions.
