New high temperature heat pump offers even more possibilities

Mitsubishi Electric has announced the launch of a new high temperature water-to-water heat pump which reduces the global warming potential (GWP) by 56% over the previous models.

The EW-HT-G05 upgrades the popular EW-HT range and uses non-flammable refrigerant R513A (GWP100 = 573 as per AR5), which has an ASHRAE A1 safety class. The existing EW-HT uses R134a refrigerant. This new version enables customers to easily replace antiquated fossil fuel heating systems by building a complete cascade system that utilizes the same refrigerant throughout.

Available in four sizes to offer 73kW to 130kW, the units include two independent refrigerant circuits and a unique plate heat exchanger to provide water temperatures up to 78°C. The dual circuits allow customers to separate their Low Temperature Hot Water (LTHW) circuit – used for Space Heating, from the Hot Water Circuit used for Domestic Hot Water (DHW).

The EW-HT is designed with a compact footprint for indoor placement, installation is straightforward, and the independent circuits mean it can operate in part load to improve efficiency during low-demand periods. Several options are also available such as touch screen display, refrigerant leak detection and Master-Client group controls.

With a wide operating envelope, the EW-HT can support a range of commercial applications by interfacing between the LTHW circuit and the DHW circuit. Units can also be harmonised with the INTEGRA range of Simultaneous Heating & Cooling equipment (4-pipe) for residential and commercial buildings, industrial process heat recovery (including IT Cooling) and district heating systems.
