NR2-FC-G06 Air Cooled Chiller PI Sheet

View & Download

Outdoor unit for the production of high temperature chilled water equipped with scroll compressors, R454B refrigerant, axial-fans, micro-channel full-aluminum condensing coils, shell and tube evaporator, and electronic expansion valves. Base, supporting structure, and panels are of galvanized epoxy powder coated steel. The free-cooling system chills the water exploiting the outdoor air cold temperatures. It consists of additional water coils, made of copper tubes and aluminum fins, and a devoted hydraulic valve system. The NG configuration complies with applications where it is not allowed or desired the use of ethylene glycol.

Features

LOW GWP REFRIGERANT

The new generation refrigerant R454B is the most eco-sustainable alternative to traditional refrigerant R410A, offering a 76% reduction in terms of GWP (Global Warming Potential GWP of R454B = 467, GWP of R410A = 1924 as per IPCC rev. 5th) and zero impact on the ozone layer.

FREE-COOLING

The generous size of the free-cooling coils allows to produce the nominal cooling capacity without the use of the compressors for many hours per year, thus cutting the annual energy consuption.

HIGH TEMPERATURE OF CHILLED WATER

Designed for the production of chilled water with high temperature and high delta T, this unit is the ideal solution for the modern IT-cooling systems, where this optimization allows great energy savings.

ELECTRICAL AND THERMAL METERING

Functions and kits for the smart metering of the electrical power consumption and the cooling capacity produced.

GROUP CONTROLS WITH DYNAMIC MASTER

Load sharing, sequencing, active redundancy, priority of resource activation, alarm management, these are only some of the LAN functions that the unit is able to manage when connected to a group of chillers. Besides, the system's stability is ensured even in case of alarm or malfunctioning thanks to the Dynamic Master logic.

HPC

This function connects the indoor units (close control) with the external group of chillers. An advanced algorithm instantaneously detects the actual indoor thermal load and conveys this information to the chillers, thus optimizing the operation of the whole system.

INTEGRATED HYDRONIC GROUP

The optional built-in hydronic module already contains the main water circuit components; available with single or twin in-line, for achieving both low or high head.

VARIABLE PRIMARY FLOW

Energy savings due to variable pump speed management based on load demand and the variable flow ensures the units also function in critical working conditions.
