Climaveneta - Model NX2-Q-G06 0344 - 0808 -Multi-purpose Outdoor Unit
Multi-purpose outdoor unit for use in 4-pipe systems for the simultaneous production of hot and chilled water by means of two independent hydronic circuits. These units are able to satisfy the demand for hot and cold water simultaneously through a system that does not require seasonal switching and is therefore a valid alternative to traditional plants with chiller and boiler. This unit is equipped with hermetic rotary Scroll compressors, with R454B, axial fans, shell and tube heat exchangers and electronic expansion valve. The range is composed of units equipped with four, six, and eight compressors in a multi-circuit configuration.
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.
INTEGRATED HYDRONIC GROUP
The built-in hydronic module already contains the main water circuit components; it is available with single or twin in-line pump, for achieving low or high head, available for both hot and cold water distribution systems (up to 4 pumps).
SHELL&TUBE HEAT EXCHANGER
The shell and tube exchanger provides the highest flexibility for the unit’s installation, keeping the pressure drops on the hydronic side at a minimum, thus representing the best choice for all the hydronic applications.
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.
ELECTRONIC EXPANSION VALVE SUPPLIED STANDARD
The use of the electronic expansion valve generates considerable benefits, especially in cases of variable demand and at different working conditions. It guarantees energy savings due to efficiency optimization in various different working conditions which translates into a reduction in operating consumption, a faster start-up of the unit and a wider extension of the operating limits.
WIDE OPERATING RANGE
Unit´s operation guaranteed with external air temperature down to -15°C during winter and up to 46°C during summer. Production of hot water up to 55°C without accessories.
WIDE CAPACITY RANGE
Units equipped with up to 8 scroll compressors in multi-circuits configuration for a wide capacity range, up to 800 kW of cooling capacity.
PATENTED VENTILATION SECTION LAYOUT
Technological solution patented by MEHITS to ensure the independent operation of the circuits, reduce the unit’s footprint and improve the efficiency at partial load both in heating mode and cooling mode.
