Project Description

Air Cooled Condensers

Air cooled condensers are used in equipment for refrigeration, air conditioning and industrial processes. Thanks to the innovations developed, patented and tested by LU-VE, the air cooled condensers produced by the company:

• Economical to run
• Function efficiently in all environmental conditions.

HEAT EXCHANGER TURBOCOIL®

The extraordinary efficiency of the LU-VE stems from the optimum combination of new fins and tubes with special helicoidal large-surface inner grooves.
Advantages:
• High capacity with low air quantity.
• Low motor power draw.
• Quiet operation.
• Reduction of internal circuit volume and refrigerant.

COIL SUSPENSION

SAFETUBES SYSTEM
The coil suspension system (SAFETUBES SYSTEM®, LU-VE patent) ensures that the tubes are completely protected during transportation, installation and operation of the air cooled condenser.

Fan Motors

Motors (3 ~ 400 V 50 Hz) feature:
• High efficiency and low consumption.
• Lifetime lubrication with incorporated heat protection.

FAN SHROUD

The highly efficient design of the mouth of the fan shroud eliminates air recirculation and reduces noise. Every fan section is separated from the others (only for SHVSAV- EHV-EAV-XAV). Fan guards conform to the most severe safety regulations in order to guarantee maximum protection

Options

• “EC” motors.
• Motors wired to the junction box.
• ALUPAINT® in painted aluminium
• CU in copper
• Configurations with more circuits
or with subcooling circuits.
• Heat exchanger protection.

Operating principles

The fluid refrigerant at the outlet of a condenser is usually collected in a liquid receiving tank, in which the liquid and vapour phases coexist. The temperature of the condensate at the outlet of the liquid receiving tank is therefore at a temperature which coincides with the condensation temperature, excluding the effects induced by the pressure drop which the refrigerant undergoes while passing through the condenser.

refrigerant subcooler

Advantages of subcooling

Subcooling the liquid condensate before expanding it and running it to the evaporator enables increased refrigerating power and increased energy efficiency to be achieved. All the heat given up to the environment during the subcooling phase is reintroduced into the refrigeration cycle as useful work (free, from the point of view of energy consumption) in the evaporation phase. An additional advantage of subcooling is the possibility of permitting pressure drops in the line which takes the refrigerant from the condenser to the expansion valve without the formation of vapours.
