Free Cooling Line - Summer Mode Free Cooling System (built-in Plate Heat Exchanger)

Using outdoor air for cooling!

When air conditioning is requested all year long, even in cold seasons, it is a shame to waste energy to produce cooling capacity when it would be just sufficient to get it from the environment. For free, for high energy saving, for a green approach to air conditioning.

With a traditional chiller technology this is not possible because of its basic design that uses compressors even in cold seasons. Switching the compressors off and chilling the hydraulic circuit with the air is today's challenge number one: maximum output, minimum input.

RELIABILITY!

When air conditioning is needed not only for comfort, but also for datacenter, mobile telecommunication or industrial applications, system’s reliability is the first and most important prerequisite. A unit failure in units with more than 8000 hours/year of working time could cause enormous damages to the entire structure. For this reason redundancy is a common, even if expensive, practice that offers reliable systems with minimized risks. As alternative a simple unit has to be installed, minimizing the number of critical components.

LOW OPERATING COSTS!

A low energy bill is more than desired when a unit is supposed to work for most of the year. A unit’s efficiency increase of only 1% in a 1 MW plant entails up to potential operating cost saving of 5.000€ per years.

What about if the entire plant could more than double its efficiency?

The energy bill will cut by half, and the money saved could put it towards the building itself, adding more value to it.

In a datacenter with 1MW cooling capacity, energy bill can rise up to 1000€/day. Thanks to the advantages offered by free-cooling technology, the operating costs can be cut down to 50€/day during winter months, adding up to a 60% saving over the whole year, depending on the location and climate profile.

HIGHEST USE OF RENEWABLE ENERGY!

More and more sustainability is the main issue that really add value to buildings. The use of green technology, in this sense, helps to gain points with the most known protocols of sustainability and moreover ensure high energy savings.

When air conditioning is a constant request all year long, even during cold seasons, the air source for a chiller operation can be considered a renewable source, available wherever, with no limitations. Design a unit, capable to chill the water with the simple and direct heat exchange between the plant hydraulic circuit and the outdoor air, is the target to achieve to comply with modern requests of green technology use.
