How it works

Alfa LU-VE finned coil air heat exchangers have been designed to achieve an optimized exchange of thermal energy between air and a refrigerant or fluid. The ‘heart’ of our air heat exchangers is the finned coil, built up from a circuit of interconnected tube serpentines and fins to increase the heat exchanging surface. Thanks to the combination of key design variables (coil materials, coil geometry, casing design, fan type), air units are very versatile heat exchangers with a great variety of applications in many industries. Alfa LU-VE supplies finned coil air heat exchanger products for a wide variety of applications.

Air-cooled gas condensers

CO₂ gas coolers replace traditional air-cooled condensers in refrigerating systems that have been designed for the use of CO₂ as a single refrigerant. Such installations are getting more and more widely used. In air-cooled gas coolers the hot, compressed CO₂ gas flows through the gas cooler coil and is cooled down by the ambient air that is forced through the coil. Due to the thermodynamic properties of CO₂, there is no phase change in the gas cooler. In CO₂ refrigerant systems the refrigerant gas is not liquefied until the next system component - the expansion valve (see illustration above). Air-cooled gas coolers operate with considerably higher pressures than air-cooled condensers.
