Trane presents free-cooling as RTAD range’s coolest thing

Trane offers a wide portfolio of environmentally responsible and fully integrated HVAC products, systems and services that enable Trane customers to create and develop sustainable buildings for now and for the future. As part of this, the specialist company has launched the free-cooling option on its RTAD chiller range.

Environmental concerns at the heart of Trane’s strategy
Owing to this option, which enables energy to be recovered via the ambient cold and the use of the refrigerant fluid R 134a (ODP = 0, GDP = low), Trane complies with current environmental requirements with regard to confining refrigerants to industrial and tertiary-sector buildings, and also with regard to contributing to the worldwide reduction in the greenhouse effect.

Considerable savings made possible by free-cooling option
The machine, fitted with the free-cooling option, is adaptable since it offers the possibility of switching from compressor mode to free-cooling mode via a built-in, three-way control valve. In this way, when the outside temperature is sufficiently low, it enables the ambient cold to be used to cool the heat transfer fluid and to limit the compressor mode so as to reduce the user’s energy bill. It is thus possible to save up to 34% of normal energy consumption, depending on the cooling load required and the number of hours during which ambient temperatures are relatively low.

This machine is especially suited to industrial processes as well as to those applications requiring a year-round cooling load. Indeed, using the free-cooling mode is especially recommended for the markets of northern Europe, due to the sizeable number of hours at low ambient temperature.

This option, built in as early as the machine's design phase, makes it possible to obtain a unit which remains compact — accessibility to the coils as well as maintenance are greatly simplified. As is the case with Trane's Series RTM chillers, and owing to its Trane helical-rotary compressors — direct drive, low speed and semi-hermetic — this machine also has the highest reliability rate on the market.
