PHOENIX Freeecooling - 1

Phoenix Free-Cooling units are the optimum solution for applications such as plastics production and any other process in which cooling is required throughout the year. By exploiting low ambient air temperatures Phoenix Free-Cooling units cool the process fluid free of charge, eliminating the energy wastage caused by running refrigerant compressors during the winter season. The total aeraulic independence of the free-cooling coils with respect to the condensing coils is achieved using dedicated fans and coils within separate compartments. This solution offers maximum efficiency in the exploitation and control of the free-cooling mode, providing a simple and reliable solution to the problems associated with conventional designs in which the free-cooling coils are positioned in front of the condensing coils and served by shared fans. In fact such conventional solutions result in a significant reduction in energy savings because of the higher power consumption of the fans and the critical conditions caused by the concurrency of conflicting requirements, namely the need to reduce the air flow for condensing pressure control and to increase it to maximise the useful free-cooling effect. As an example of the extensive energy saving potential this technology offers, for a 24 hour/day production cycle the unit could operate in free-cooling for 90% of its operating cycle, resulting in energy savings in the region of 40-50%. > Apart from managing the free-cooling parameters, the innovative software, specifically developed by MTA, controls the automatic rotation of the compressors start sequence, the unloading procedure and the management of the optional electronic thermostatic valves.The microprocessor also interfaces with peripheral systems at several levels, from user to supervision network level. GSM modem connection is offered, as is guaranteed compatibility with the most widely used BMS system communication protocols: BACnet, Lonworks, and ModBus. > C - standard; SC - low noise; SF - low noise (for high ambient temperatures); SSN - super-silent; Low ambient temperature version (min. -15 C).Е Օ Օ > Compressors cover (for C only, standard on other versions); Phoenix Free-Cooling units are generally installed in high capacity plants requiring maximum energy savings and absolute reliability. The semi-hermetic twin screw compressors ensure continuous and reliable operation thanks to the reduced number of moving parts, the absence of suction and discharge valves and the presence of oil pumps, as well as a unique patented lubrification system.
