Chiller Feature
Features added to e-series inverter range
MITSUBISHI ELECTRIC AUSTRALIA has ex- panded its ‘off-the-shelf” high efficiency, inverter driven e-series modular chiller line-up by adding new 150 and 180kW modules.
The new top discharge air-cooled modular chillers offer exceptional part load efficiencies, improved energy savings, reduced footprint and a host of advanced features and benefits.
“THE UPDATES MADE TO THE E-SERIES CHILLER RANGE ALLOW BUSINESSES TO MEET NEW ENERGY EFFICIENCY REQUIREMENTS.”
These modules are available as both heat pump and cooling only option. With four high ef- ficiency inverter scroll compressors operating as two pairs in each module and the ability to con- nect up to six individual modules into one sys- tem, the additions make for exceptional part load efficiencies.
This means that the e-series expansion is likely to be of particular interest to building designers, manufacturers, managers and own- ers who are aiming to comply with govern- ment energy legislation while balancing the requirement to provide comfortable, produc- tive environments for occupants or for process cooling applications.
Mitsubishi Electric Australia’s national product manager, Atesh Mani, said the Aus- tralian Government is focused on a 26-28 per cent reduction in greenhouse gas emissions from 2005 levels by 2030.
“This means that legislation and initiatives they are putting in place, such as minimum en- ergy performance for new buildings or major re- furbishment, are impacting how businesses build,” he said.
“The updates made to the e-series chiller range allow businesses to meet these efficiency requirements and create a comfortable work environment.”
Another key feature of the range is optimum frequency control. The embedded logic will max-

imise overall efficiency of the system by operat- ing the compressors in high efficiency operating range under part load conditions.
This feature in the e-series chiller line-up is beneficial to improve overall efficiency of the me- chanical plant whether it comprises a single module or even up to 24 modules.
These new units have an even smaller foot- print than the existing 90kW e-series modules and each slim unit can be positioned in a bank of up to six connected units using the same inter- nal header, saving on piping space and equip- ment costs.
Available as a cooling only or heat pump ver- sion, the chiller is suitable for both comfort and process cooling applications.

Company fined for HCFC imports
A VICTORIA BASED company that imports, manufactures and supplies air conditioning equipment has been fined $12,600 for importing bulk hydrochlorofluorocarbon (HCFC) without a controlled substances licence.
The fine was issued by the Department of Ag- riculture, Water and the Environment.
Importing HCFC without a licence is an of- fence under the Ozone Protection and Synthetic Greenhouse Gas Management Act 1989 (the Act), which is in place to protect the environ- ment by reducing emissions of ozone depleting substances and synthetic greenhouse gases.
Importers and exporters of bulk HCFC who hold a controlled substances li- cence, must comply with a
HCFC quota.
The substance, identified as
HCFC-22/R-22, was supplied by an overseas equipment manufac- turer to fill uncharged equip- ment it had shipped to the com- pany. The company holds an equipment licence to import equipment charged with sched- uled substances. However, a con- trolled substances licence and HCFC quota must be held to im-

port or export bulk quantities of HCFC. The company was also fined for using dispos-
able cylinders for storing R-22.
This was in contravention of the company’s
Refrigerant Trading Authorisation conditions – an offence under the Ozone Protection and Syn- thetic Greenhouse Gas Management Regula- tions 1995.
Disposable cylinders containing scheduled substances such as R-22 are banned in Australia. These types of cylinders cannot be refilled, which means a residual ‘heel’ amount of gas can remain in the containers and can enter the at- mosphere once disposal of the cylinder occurs.
A priority compliance focus for the depart- ment is to reduce emissions of synthetic greenhouse gases and ozone depleting substances. The company has paid the infringement notices and is now complying with licensing requirements and conditions.
Since January 1, 2020, importers can no longer import HCFC equipment, or equipment de- signed to operate solely on HCFCs, unless an ex- emption is held.
