Mitsubishi Electric e-series chillers

Mitsubishi Electric Australia has launched a range of inverter-driven chillers to the Australian market. The e-series modular chiller range is designed to answer the need for controllable, energy-efficient cooling and heating, with reduced plant size and a host of benefits.

The e-series chiller (available in heat pump and cooling-only modules) uses two DC inverter-driven scroll compressors in each 90 kW module, taken from the VRF (variable refrigerant flow) sector, to deliver a capacity range of 8–100%. The models deliver high levels of efficiency, with the ability for units to operate on their own or in tandem with others.

The shape and modular design of the series mean that the system can be constructed with up to six individual units connected together, to provide a capacity of between 90 and 540 kW. The use of U-shaped heat exchangers offers a greater surface area and also means that the units are narrower than conventional systems.

The 90 kW modules can be positioned next to each other in a row, with up to six units using the same inbuilt internal header. For larger systems, it is also possible to have double rows of the units with a gap of only 900 mm service space.

The series achieves quiet noise levels, which is increasingly important in inner city locations. These low noise levels are achieved through both the construction and design of each unit as well as the component technology within each chiller, which is also easily integrated with new and existing systems using BMS control.
