Heat Exchanger Core Introduction

The Heat Exchanger Core is an energy-saving device used for energy recovery in air conditioning exhaust. Its main components include the housing, heat exchange core, and filter. Due to the use of materials with thermal and permeable properties in the heat exchange core, it can pre-cool and dry fresh air in summer and preheat and humidify fresh air in winter when applied to air conditioning systems, significantly reducing the load on fresh air, thereby saving energy consumption of the cooling and heating systems. This is highly beneficial for small-scale systems in terms of saving operating costs and reducing peak electricity consumption. The total 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 Full Heat Recovery Air-to-Air Exchanger (Full Heat Recovery Core)

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

To achieve both energy efficiency and comfort, a full heat exchanger is necessary, which can perform heat exchange while also facilitating air exchange.

A representative full heat exchanger material, composed of specially processed partitions and spacers. The airflows for intake and exhaust are completely separated by the partitions, ensuring that intake and exhaust air do not mix, thereby maintaining the introduction of fresh external air. Through the special processing of paper in the full heat exchanger material, it utilizes its thermal conductivity and moisture permeability properties to facilitate heat transfer (sensible heat) exchange as the intake and exhaust air pass through the material; and utilizes the humidity difference (latent heat) through the vapor pressure difference across the specially processed paper of the partitions for full heat exchange.
