Inverter Scroll Chillers - Heat Pump - Ocean Black Fin
LG has launched a new range of air-cooled, inverter scroll chillers into the UK market. The new heat pump and cooling only options, are available in 60kW, 123kW and 185kW (cooling capacity) models. The new chiller range from LG offers superior performance and alongside industry energy efficiency in ‘part-load’ conditions, the Inverter Scroll Chillers boast an impressive EER 2.65 / COP 3.2 / ESEER 4.79. The new range is ideal for applications where space is an issue – these chillers are compact, with a foot print area of only 4.9m², ideal where space is at a premium. The LG units feature low noise - at just 68dB(A) and can offer reduced noise levels at night, simply by adjusting the fan RPM.
HVAC systems are generally sized at their peak efficiency when they are working at maximum capacity, which only occurs less than 5% of the systems operational time. This is highly inefficient when most units operate mainly at partial load. So it is important to check part-load efficiency. At part-load, when cooling output can be reduced, inverter chillers can operate linearly with a wide operational range, becoming more effective than chillers operating at a constant output. Efficiency can clearly be improved whenever the compressor speed can be reduced to more closely match the load.
Inverter Compressor
With LG’s designed and manufactured inverter scroll compressor
boasting higher energy efficiency in overall operation range
especially in part-load, this reduces operation costs for the
end user. The compressors include the implementation of LG’s own
patented HiPOR technology (High Pressure Oil Return) and vapour
injection compressor return as seen in their VRF systems. The
system effectively resolves the issue of compressor energy
wastage, providing excellent operational savings and a wide
operating range of 15 – 125Hz.
Ocean Black Fin
Equipped with LG’s exclusive Ocean Black Fin anti-corrosion
coating, the inverter scroll chillers heat exchanger is
protected to reduce the effects of corrosion normally found in
coastal and industrial environments. The 2-part coating consists
of a black epoxy resin - providing the resistance - and a
hydrophilic coating to minimise the accumulation of moisture,
which would accelerate any chemical reaction. The durability
provided from Ocean Black Fin prolongs the product’s life span
in the most challenging environments, paving the way for
exceptional, long-lasting performance and improved heating
performance.
Modular Design
The simple design of the air-cooled system allows the user to
effectively maximise space. The chiller system can be easily
extended if needed by modular design. This is a definite
advantage in remodelling or extension work. A single unit of
185kW can be added up to a maximum of 925kW operating from one
controller, or a combination of 10 units from a centralised
control.
Controls
The 5" LCD touch controller is capable of a wide array of
functions, including cycle monitoring, schedule control and
demand control. It can also be installed at a distance of 500m
from the chiller if needed. One controller can be used to
control up to 5 units of chillers, saving both time and money.
A maximum of 10 chillers can be controlled remotely by central controller and direct BMS communication, up to 1,850kW.
Reliable
Continuous heating minimises the decrease of water outlet
temperature during defrosting for multi circuit models.
The back up operating system helps the entire HVAC system to continue to operate by removing compressors or system circuits from operations until repair or diagnosis is complete.
LG MV assists engineers with commissioning, monitoring and data recording of all LG systems including the air-cooled chillers. Cycle diagrams provide an easy understanding of the product operation and coupled with built in trouble shooting guides, provides a quick and easy insight to LG’s range of products.
"The introduction of air source inverter scroll chillers equipped with our quality proven VRF technologies, compliments our current product line up, says Andrew Slater, Technical Research and Development Senior Manager at LG UK. “Moving industry leading seasonal efficiencies into a variety of applications has never been easier. With a common structure of control logic and both electrical and mechanical components, we have made the transition for service and design engineers currently working with our air conditioning products to our new chiller range a simple process."
