The purpose of heat exchangers is to transfer heat from one fluid (either gas or liquid) to another. Compact heat exchangers (CHEs) have a significantly greater surface area per unit volume and more conventional types of heat exchanger. For the purposes of the ECA Scheme, a CHE is defined as a heat exchanger with a surface to volume ratio of > 200 m2/m3.
Compact heat exchangers are characterized by a high surface area per unit volume, which can result in a higher efficiency than conventional heat exchangers, in a significantly smaller volume (typically Compact heat exchangers can be achieve efficiencies of over 95% cf. 80% for non-compact heat exchangers). Compact heat exchangers transfer more energy cost-effective manner than other heat exchangers & save more energy when compared standard technology.
Three types of compact heat exchanger are covered by the ECA Scheme. These are:
1. Plate heat exchangers.
2. Plate-fin heat exchangers.
3. Compact heat exchangers with precision formed surfaces.
