Daikin covers all phases of cold chain
DAIKIN AUSTRALIA HAS launched its commercial refrigeration condensing units in conjunction with the launch of a new strategic business unit.
“The new refrigeration business unit aims to provide solutions in all phases of the cold chain, introducing a wide line of refrigeration equipment from industrial to commercial use,” according to Gaurav Malik, general manager for the company’s applied and solutions business.
The condensing units are manufactured by J&E Hall, a worldwide member of the Daikin Group and one of the world’s foremost refrigeration solution providers.
Combining design innovation and energy efficient technology, the J&E Hall condensing units have a number of advanced features and functions.
Microchannel heat exchanger (on selected models) technology reduces the refrigerant
volume in the system more efficiently than traditional fin and tube heat exchangers to provide savings on installation costs.
A new adjustable fan speed and pressure switch* provide added flexibility to deliver optimal operation for the chosen refrigerant.
Better energy efficiency and the top-quality components will improve reliability and longevity. Low fan speeds and the acoustically lined condensing unit casing will ensure quiet operation.
These condensing units will offer a smaller footprint unit taking up less space, a better
“INSTALLATION AND MAINTENANCE ARE SIMPLE AND EASY.”
solution for noise sensitive projects, whilst reducing energy costs. Available in Medium Temperature (0.9 – 15.5kW) and Low Temperature (0.8 – 12.8kW).
Installation and maintenance are simple and easy. J&E Hall has a full range of reciprocating and scroll condensing units in various casing sizes with multi-refrigerant options, providing installation flexibility.
Access to major components is available through the front and side via hinged doors (on selected models) for trouble-free maintenance. The condensing unit casing is powder coated to enhance resistance to corrosion, offering longer term reliability.
Daikin Group is taking steps to integrate its commercial refrigeration operations in Australia further. With 100 years of experience in the refrigeration business, Daikin has extensive expertise in refrigerants, controls, and compressors.
Sixth generation VRV hits sweet spot
DAIKIN AUSTRALIA HAS launched the newest addition to its VRV range – the VRV R Series (REYQ-BYM).
The sixth-generation model enables simultaneous cooling and heating operation in a single VRV system and boasts a number of improvements over previous generations.
The new system was designed for both single and multi-module combinations that help to reduce the overall space required for mechanical equipment and the number of electrical and piping connections.
Single modules starting at 8HP capacity are now available in three sizes thanks to the addition of a large-capacity XL chassis with 22 and 24HP (67.0kW) capacity that sits at 1,750mm wide x 765mm deep x 1,660mm tall.
This represents a four per cent reduction in total footprint and 11 per cent reduction in weight compared to the fifth-generation VRV Series.
The new VRV R is equipped with hardware and software innovations designed to improve the energy efficiency of the system.
The patented High Efficiency P-Type Compressor is optimised for part-load performance and delivers a part load EER (at 50 per cent load) of up to 7.82.
This represents an efficiency improvement of 25 per cent.
Refrigerant piping lengths of up to 165m are possible and the maximum height difference between the indoor unit and the outdoor unit has been extended to 110m, an improvement of 20m from the fifth-generation model.
The new system was designed for both single and multi‐module combinations.
