i-FX-N-G05-Y 0472 - 1152

Reversible unit, air source, VSD screw compressors and EC fans, for outdoor installation. 444 - 1154 kW

Outdoor heat pump unit for the production of chilled/hot water with semi-hermetic variable-speed screw compressors optimized for R513A, EC fans, external coil with copper tubes and aluminium fines, shell and tubes heat exchanger designed by Mitsubishi Electric Hydronics & IT Cooling Systems S.p.A. and electronic expansion valve. The screw compressors feature the variable speed technology thanks to the integrated refrigerant cooled inverter, for the maximum compactness and operating flexibility. Moreover, they feature the Variable Vi (compression ratio) technology, to change the internal geometry according to the operating conditions. Thanks to the accurate sizing of all internal components and the use of variable speed technology, the unit ensures flexibility, reliability and maximum efficiency in every operating condition. These units are designed for two-pipes systems and are able to produce hot or cold water, according to the selected operation mode.

Features

HIGH EFFICIENCY

High full load and partial load efficiency in both heating and cooling, using inverter technology to continuously modulate compressors operation and EC fans as standard, in order to deliver the exact amount of energy based on the actual needs of the plant. High efficiency means reduced energy consumption throughout the entire year, for any operation mode and any outdoor condition.

ErP COMPLIANT 2021

Thanks to the inverter technology and the accurate design, the units already comply and exceed the minimum seasonal energy efficiency requirements that will start from 2021, imposed by the eco-sustainable design Directive 2009/125/EC.

LOW GWP REFRIGERANT

New generation refrigerant R513A, with reduced greenhouse effect in comparison with traditional HFC refrigerants (Global Warming Potential GWP of R513A = 572, GWP of R134a = 1300 as per IPCC rev. 5) and zero impact on the ozone layer. Non-flammable (ASHRAE 34, ISO 817: class A1).

COMPACTNESS

Compactness in terms of overall size and weight, improving installation and on-site maintenance.

HOT WATER SUPPLY

Supply of hot water in use up to 60°C, offering maximum versatility with respect to different plant engineering solutions.

ADAPTABILITY

Can adapt to the building’s heating request thanks to the continuous capacity regulation, assured by the control’s sophisticated logic.

UNIT AND PLANT HARMONY

Low inrush current and a higher power factor than similar fixed speed units, provide an easy electrical installation which is not stressed during start-up nor are extra devices for power factor correction needed. The use of VSD technology allows the unit to partialize in a stepless way, with consequent lower leaving water temperature fluctuations.

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.

WIDE OPERATING RANGE

Unit´s operation guaranteed with external air temperature down to -12°C during winter and up to 50°C during summer. Production of hot water up to 60°C without accessories and chilled water from -8°C to +20°C in order to suit any possible application.

Electronic control W3000+

W3000+ features an easy-to-use interface and a complete LCD display that allows one to consult and intervene by means of a multi-language menu (19 languages are available). The diagnostics includes a complete alarm management, with the “black-box” and the alarm history display for enhanced analysis of the unit operation. The programmable timer manages a weekly schedule organized into time bands to optimize unit performance by minimizing power consumption during periods of inactivity. Up to 10 daily time bands can be associated with different operating set points. As option, KIPlink is available - Keyboard In Your Pocket. KIPlink is the innovative user interface based on WiFi technology that allows one to operate on the unit directly from the smartphone or tablet. The regulation is based on the patented “Quickmind” water temperature regulation logic uses self-adapting control to maintain flow temperatures and optimize performance even in low water content scenarios. As an alternative, the proportional or proportional-integral regulations are also available. Optional proprietary devices can perform the adjustment of resources in systems made of several units. Consumption metering and performance measurement are possible as well. Supervision can be easily developed via proprietary devices or the integration in third party systems by means of the most common protocols as ModBus, Bacnet-over-IP, Bacnet MS/TP RS485, Konnex, ModBus TCP/IP, SNMP. Compatibility with the remote keyboard (up to 8 units).
