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.
Set-up for remote connectivity with protocols: ModBus, ModBus over IP (TCP/IP), Echelon, BacNet MS/TP RS485, Bacnet over IP, Konnex, SNMP
Traditional coils with copper tubes and alluminium fins, also available with prepainted fins or Fin Guard Silver protective treatment.
Night mode to limit the maximum noise level of the unit.
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.
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.
Can adapt to the building’s heating request thanks to the continuous capacity regulation, assured by the control’s sophisticated logic.
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.
HOT WATER SUPPLY
Supply of hot water in use up to 60°C, offering maximum versatility with respect to different plant engineering solutions.
