FX-W-G04-Y 0551 - 2002

Water cooled chiller 93,2 - 373 kW

Indoor unit for the production of chilled water featuring semihermetic screw compressors optimized to operate with low compression ratio, refrigerant HFO R1234ze, shell and tubes evaporator designed by Mitsubishi Electric Hydronics & IT Cooling Systems S.p.A. and shell and tube condenser and electronic expansion valve. Base and supporting structure are made of polyester painted galvanized steel. Eurovent certification. The unit is extremely compact thanks to the peculiar construction layout, without base frame and panels, and extremely flexible to easily adapt itself to different thermal load conditions thanks to the precise thermoregulation. The high performance’s level is achieved thanks to the accurate sizing of all internal components.

Features

LOW GWP REFRIGERANT

4th generation refrigerant HFO 1234ze, with negligible greenhouse effect in comparison with traditional HFC refrigerants (Global Warming Potential GWP of HFO 1234ze < 1, GWP of R134a = 1300 as per IPCC rev. 5th) and zero impact on the ozone layer.

ErP READY

Thanks to the high level of efficiency at part load, the unit can meet and exceed the minimum energy efficiency threshold rated by the Seasonal Energy Performance Ratio SEPR HT and SEPR MT, in accordance with the eco-sustainable design requirements for all products using energy. The unit is already compliant with the minimum seasonal efficiency requirements that will start from 2021.

MAXIMUM COMPACTNESS

Maximum compactness offers very high flexibility in the design process and installation operations, offering a premium solution in case of reduced clearances or when retrofitting existing installations.

ADAPTABILITY

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

ELECTRONIC EXPANSION VALVE SUPPLIED STANDARD

The use of the electronic expansion valve generates considerable benefits, especially in cases of variability of the source temperature. The electronic expansion valve guarantees speed in reaching machine stability and an extension of the operating limits.

Electronic control W3000TE

The W3000TE controller offers advanced functions and algorithms. The Compact keypad features an easy-to-use interface and a complete LCD display that allows consulting and intervening on the unit by means of a multi-language menu (19 languages are available). The regulation is based on the patented “Quickmind” water temperature regulation logic uses self-adapting control to maintain flow temperatures and optimise performance even in low water content scenarios. As an alternative, the proportional or proportional-integral regulations are also available. The diagnostics comprises a complete alarm management system, with the “black-box” (via PC) and the alarm history display (via display or also PC) for enhanced analysis of the unit operation Optional proprietary devices can perform the adjustment of the 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, Bacnet-over-IP, LonWorks. Compatibility with the remote keyboard (up to 8 units). The defrosting (air source reversible unit only) follows a proprietary self-adaptive logic, which features the monitoring of several operational parameters. This allows to reduce the number and duration of the defrost cycles, with a benefit for the overall energy efficiency.
